|This section is for storm chases done in the central / Midwestern United States during the year of 2010 that were not part of the main chase log (mainly for my home state of Florida) and also not part of any dedicated chase expeditions in 2010 (such as the one for May 18 through June 1). Here you should find many pictures of lightning, possible tornadoes, along with many severe thunderstorm elements. Keep in mind that this chase log is scientific evidence and portrays my on-going storm chasing research. It has been placed on this page for easy reference and meteorological interests.

1). April 22, 3:30 PM - Interception and observation of an extremely severe thunderstorm between Guymon, Oklahoma and Liberal, Kanasas from along Highway 54 (Near Hooker / Tyrone) mainly in Texas County, Oklahoma and Seward County, Kansas. The storm was a classic supercell thunderstorm, and produced at least one weak tornado during its observed life-cycle of a couple of hours. A possible view of the brief tornado was made from a distance of about 5 miles. The storm core was not penetrated, but winds (inflow) of about 35 MPH were experienced, along with frequent lightning. The storm core also had hail at least golfball sized. Conditions causing the storm were a dryline / frontal boundary interaction (triple point), surface heating, a low pressure area, and strong winds (divergence) aloft / wind shear. A 2009 Kia Forte was used to chase the storms. Documentation was still digital photos and HD video. A tornado watch was also in effect for the area until 10 PM CDT.
2). April 22, 6:30 PM - Interception and observation of an extremely severe thunderstorm near Perryton, Texas in Ochiltree County from along Highway 83. The storm was a classic supercell thunderstorm with a possible tornado (not directly observed). The main core of the storm (also with 60 MPH+ winds and frequent lightning) was not penetrated, however, a region of large hail (1") covering the ground was encountered with inflow winds to near 50 MPH roughly 5 miles from the storm core (hail was falling from storm anvil). Conditions causing the storm were a dryline / frontal boundary interaction (triple point), surface heating, a low pressure area, and strong winds (divergence) aloft / wind shear. A 2009 Kia Forte was used to chase the storms. Documentation was still digital photos and HD video. A tornado watch was also in effect for the area until 10 PM CDT.
3). April 23, 4:00 PM - Observation of an very severe thunderstorm near Perryville, Arkansas in Perry County near Highways 9 and 10. The storm was a multicell storm cluster with an embedded and intense HP supercell. The storm was also tornado warned (radar indicated). The of this storm was not penetrated, but the chase path came across hail fig and a hail accumulation on the ground behind the storm near Harris Brake reservoir. The storm core contained winds to about 60 MPH and hail up to 1". The storm was followed to near I-40 and the town of Morrilton (where tornado sirens were activated). Conditions causing the storm were surface heating, a low strong pressure area, and strong winds / cold air aloft. A 2009 Kia Forte was used to chase the storms. Documentation was still digital photos and HD video. A tornado watch was also in effect for the area until 8 PM CDT.
4). April 23, 6:00 PM - Observation and penetration of a strong to severe thunderstorm near Lonoke, Arkansas in Lonoke County along and near Highway 70. The storm was a multicell storm and contained winds near 60 MPH, small hail, torrential rains, and frequent lightning. Conditions causing the storm were surface heating, a low strong pressure area, and strong winds / cold air aloft. A 2009 Kia Forte was used to chase the storms. Documentation was still digital photos. A tornado watch was also in effect for the area until 8 PM CDT.
5). April 23, 9:00 PM - Observation and penetration of a very severe thunderstorm near Prescott, Arkansas in Nevada County along and near Interstate 30 and southward along Highway 371 (eventually to near Stamps). The storm was a supercell storm (possibly tornadic) and contained winds over 70 MPH, large hail to about 1", torrential rains, and frequent lightning with some close hits. The tornado (if any) was not observed once in the rain-free region of the storm. Conditions causing the storm were surface heating, a low strong pressure area, and strong winds / cold air aloft. A 2009 Kia Forte was used to chase the storms. Documentation was still digital photos and HD video. A tornado watch was also in effect for the area until 3 AM CDT the next day.
6). April 24, 4:30 AM - Observation of a very severe thunderstorm at a motel off exit 223 of Interstate 30 in Texarcana, Arkansas in miller County. The storm was an intense multicell storm that pushed through the area, and the observation was made right at where I was staying for the night. Winds over 60 MPH, hail up to 1", some covering the ground and entering the room of the motel when the door was opened, torrential rains, and very frequent lightning with close hits. Conditions causing the storm were surface convergence, an approaching area of strong low pressure, and strong winds / cold air aloft in a highly sheared environment. A 2009 Kia Forte was used to chase the storms. Documentation was HD video. A tornado watch was also in effect for the area until 8 AM CDT.
7). April 24, 11:30 AM - Observation and indirect penetration of an extremely severe and violent tornadic thunderstorm from northwest of, and to near Yazoo City, Mississippi in Yazoo County from highways 49 and 61 with the chase coming to and end near Highways 49 and 16. This storm was a violent, and long-track HP supercells storm, that originated in northeastern Louisiana, crossed the ENTIRE state of Mississippi, then weakened in western Alabama. The storm was also a very fast-moving storm, so getting in front of the storm was difficult. The storm core had large hail and very strong winds. The most tragic aspect of this supercell was the large long-track tornado it produced, with a 100-mile long path, and a width of 1.75 miles! A brief view of this tornado, although rain-wrapped, was encountered in the storm core, about 3-5 miles northwest of Yazoo City. Tress / other small debris was also noted falling OUT of the sky in this area. A path was chosen to divert to the northeast and around the storm because of the danger, coming back around to 49 and heading south into Yazoo City. Winds at least 70-75 MPH were encountered in this area, from the east and southeast. The damage path was encountered behind the storm, still in strong winds and rain, and much of the area south of town, near Highway 49 and 16, had catastrophic EF-4 tornado damage. The chase had to be aborted to help with clearing roads / assisting emergency personnel in Yazoo City. The storm containued to the NE out of sight thereafter, as I was helping with the victims of the storm. Unfortunately, 4 people were killed in Yazoo city, so this is NOT a happy chase log. Conditions causing the storm were surface convergence, an approaching area of strong low pressure, and strong winds / cold air aloft in a highly sheared environment (divergence aloft and strong veering of winds with height). Helicity in this area was also a staggering 1000 with CAPE near 3,000 (and EHI of near 19)! A 2009 Kia Forte was used to chase the storms. Documentation was digital stills HD video of the damage / emergency efforts. A PDS tornado watch was also in effect for the area until 1 PM CDT (and extended to 8 PM CDT).
This concludes the Chase Log for the US Great Plains, Midwest, and deep south tornado chase trip from April 21 through April 25, 2010. This chase summary includes a total of 7 strong / severe thunderstorms, out of which, 2 tornadoes were observed. One of the tornadoes was a violent long-track (EF-4) tornado that struck Yazoo City, Mississippi on April 24 with devastating, and fatal results. The main chase vehicle conducting all chases was a 2009 Kia Forte. This information was prepared exclusively for the National Weather service and the team of Skywarn storm spotters.
|Here is all my chase gear, clothes, and electronics packed tightly into a mere two carry-on bags for the 5 day chase trip. Packing light and in a carry on saved time and threat of equipment damage. I always love the expressions on the TSA people at the airport when the bags go through the X-Ray machine!|
|Here is a picture of the chase rental vehicle, a 2009 Kia Forte, ready to go with equipment mounted and running. The electronics are all powered by a long cable that clips to the battery terminal, protected by its own fuses, and runs to the invertor, laptop, radio, and such in a simple and quick setup.|
|Here is a picture of the first developing supercell storm southwest of Liberal, Kansas (near and northeast of Guymon, Oklahoma at the time (view is southwest). Note the "turkey tower" of cumulus in the foreground billowing upwards, then getting toppled over by the directional (and bulk) shear.|
|Approaching the supercell storm near Hooker, Oklahoma. Nice rain-free base becomes evident.|
|Here is a radar image (base reflectivity) of the supercell storm as it was southwest of Hooker, Oklahoma. The view is to the southwest.|
|Looking closely at the wall cloud and updraft region of the supercell, a funnel / possible weak tornado is visible (center). The view is also to the southwest.|
|Here is another funnel that developed as the storm drew a bit closer, with a rotating wall cloud (center). The view is to the west.|
|Here is another picture of the rapidly rotating wall cloud / funnel just before the storm became occluded and weakened. This was near Hooker, oklahoma along Highway 54. The view is to the northwest.|
|This is a picture of the anvil blowoff at high altitudes near Perryton, Texas just east of another supercell storm. The view is to the south, and the interesting thing is the upper-level divergence (difluence) can be seen as the anvils (one from the supercell out of frame to the right, and from the storms farther away) get farther apart as one proceeds eastwards (to the left in this picture).|
|This picture appears to be far away from the Paerryton, Texas supercell storm to be concerned (it's updraft is far to the right to the southwest in this picture). However, hail up to 1" is falling from the anvil of the storm and into the "clear blue" air, and actually covered the ground at one point!|
|Interesting shelf cloud associated with a multicell / HP storm north of Pampa, Texas while headed south along Highway 70. The view is to the south, and the inflow can easily be seen going from left to right.|
|These interesting wave / rotor clouds (looks like mid-level HCR's) were encountered in the mid-levels over eastern oklahoma / western Arkansas. Most likely this is a result of directional shear in the atmosphere.|
|This is the visibility out the front windshield during one of the severe storm penetrations near Lonoke, Arksansas.|
|This is a base reflectivity radar of the supercell storm not far from Prescott, Arkansas. Notice the white circle of my GPS position (heading was SW along I-30 and into the core and rain-free area) - Yikes!|
|A poor-visibility view from inside the supercell core near Prescott while it was producing 70 MPH+ winds and hail up to 1".|
|Cloud to earth lightning strike on the backside of the thunderstorm complex from near Beck, Arkansas.|
|Here is a picture of the door of my motel room and hail coming into the door in Texarkana, Arkansas in the early morning hours of April 24. This night-time severe storm was the very start of a tragic day of severe weather.|
|Here is a view of the back-sheared anvil of the violent HP supercell storm about 30 minutes before it struck the town of Yazoo City, Mississippi. The view is to the south, and taken from near Hollandale.|
|This is another view, looking to the southwest, when closer to the soon-to-be Yazoo City supercell. The dry-punch of air creates a clear slot that pushes into the unstable air in a highly sheared environment (not the blow-off in the top of the picture, and cumulus line).|
|Destroyed church in Yazoo City, Mississippi near the junction of Highway 49 and 16.|
|Major structural damage in Yazoo City, Mississippi just west of Highway 49.|
|High end EF-3 to EF-4 damage in Yazoo City, Mississippi.|
|Dazed - But otherwise OK - Yazoo City locals stand outside a building that was nearly completely destroyed by the tornado.|
|Locals wandering unscathed out of the hardest hit area of Yazoo city, along Old Benton Road. These people were very lucky, most likely because timely warnings were given for the storm, and they sought shelter in their basement / closet. Note the live downed powerlines in the foreground.|
|Freshly destroyed home on the south side of Old Benton Road, Note the ruptured water pipe creating a fountain.|
|Some Yazoo City locals, also lucky to be uninjured, standing aside an overturned (and mangled) pickup truck, as the first heavy equipment clears the way for emergency crews to enter the hard-hit areas off Old Benton Road.|
|The TVN (Tornado Videos) group of storm chasers was also on this storm, and also stopped to assist. Storm chasers do not like to meet one another in such dire places. It's a sad thing. The "Domonator" vehicle, very similar to the TIV, is also designed to penetrate tornadoes, but not ones as stong as this.|
|This is a chain-link fence after the tornado. The air flowing through this fence was filled with debris and "projectiles", which became trapped in the fence ... Try to imagine what would happen to anyone standing in this place during the tornado.|
|My part of the stop-and-help work was to help with clearing the roads of tree and other debris. Here a few locals were cutting up the fallen trees so they can be moved by a group of men. Each cut log section weighed hundreds of pounds ... But the tornado moved these as they were whole trees (along with vehicles, roofs, etc) as if they were blowing dust.|
|this road sign, all twisted and mangled, was no match for the 170 MPH+ core winds of the Yazoo City tornado. This was also one of many "objects" that moved around the tornado's debris field at aircraft speeds during the storm.|
|Destroyed bill board sign on the south side of Yazoo City near Highway 16 and along Highway 49.|
|The painful reminder of the Yazoo City tornado disaster is mirrored on CN on one of the televisions at the Dallas Airport as I wait for my flight back to Florida. Going home with this in the back of my mind (having experienced the event first hand) is quite humbling.|
|The distinct signature of a thunderstorm updraft peeks above the turbulent high-altitude cirrus deck while flying over the northern Gulf coast and encountering the line of severe thunderstorms (near eastern Alabama at this point) on April 25. The white "dome" (lower-center) is the top of a thunderstorm updraft, probably 50 to 100 miles away. We were flying at about 38,000 feet.|

1). May 10, 4:30 PM - Observation of an extremely severe and violent tornadic thunderstorm in Grant County, Oklahoma from near Highway 81 and the town of Renfrow. The storm was a classic supercell thunderstorm that evolved to a violent HP storm that produced at least two tornadoes, both multi-vortex in nature, and one a wedge tornado west of Renfrow, Oklahoma. Both tornadoes were observed, one (near Wakita, Oklahoma) from a distance, and the multi-vortex / wedge from a few miles directly in its path. Large hail was also observed falling from the anvil of the storm, up to 1", with 50-60 MPH inflow winds. The main core of the storm was not penetrated. Light rain and frequent lightning was also noted with the supercell. Damage was anywhere from downed trees to major damage to homes in the tornados path, particularly near the town of Renfrow. The storms were caused by an intense (Colorado) low-pressure system, upper-level low, dryline and warm-front (triple-point) interactions, and surface heating. Documentation was digital stills and HD video. A 2009 Kia Forte was used to chase the storm. A PDS tornado watch was also valid for the area until 10 PM CDT.
2). May 10, 6:30 PM - Observation of an extremely severe and tornadic thunderstorm in Osage County, Oklahoma from near Highway 60 and from Ponca City to near Pawhuska. The storm was a large classic supercell thunderstorm with multiple areas of rotation. An indirect penetration was executed across the storm core and rain hook, and into the rain-free (mesocyclone) of the storm. Hail up to 2" was observed, with very heavy rains, lightning, and 60-70 MPH wind gusts. A possible tornado, although rain wrapped but weak, was encountered west of Burbank, Oklahoma. Leaves / tree debris was also noted falling from the sky. Farther east, two tornadoes were observed, one at a distance, to the east near Pawhuska, and another closer to the north of Highway 60 near Shidler. Tree damage and downed powerlines were encountered with this storm. The storms were caused by a strong low-pressure system, upper-level low, approaching dryline, and surface heating. Documentation was digital stills and HD video. A 2009 Kia Forte was used to chase the storm. A PDS tornado watch was also valid for the area until 10 PM CDT.
3). May 10, 7:30 PM - Observation and penetration of a very severe thunderstorm in Chautauqua County, Kansas from near Highway 99 and Highway 166 near the town of Sedan and eastward to southeast of Havana. The storm was a supercell storm, possibly formerly tornadic, evolving to an intense line segment as the dryline boundary surged in from the west. The storm had winds gusting near 60-65 MPH, torrential rains, lightning, and small hail. The storms were caused by a strong low-pressure system, upper-level low, dryline, and surface heating. Documentation was digital stills. A 2009 Kia Forte was used to chase the storm. A PDS tornado watch was also valid for the area until 10 PM CDT.
4). May 11, 5:30 PM - Observation of a short-lived but severe thunderstorm southwest of Cordell, Oklahoma along Highway 55 and towards Carter in Beckham county. The storm was an LP supercell developing ahead of a dryline bulge. During its high point, it probably had dime-sized hail and strong inflow winds (over 35 MPH). The core of the storm was not penetrated. The strong capping inversion, and lack of substantial forcing to over come it, caused the storm to quickly dissipate, leaving only an orphan anvil behind. The storm was caused by a dryline, upper trough, surface trough, and surface heating. Documentation was digital stills and HD video. A 2009 Kia Forte was used to chase the storm. A tornado watch was also valid for the area until 10 PM CDT.
5). May 11, 8:30 PM - Observation of an extremely severe and tornadic thunderstorm west of Vici, Oklahoma along Highway 60 in Ellis and Woodward counties. The storm was a supercell thunderstorm, starting out as classic (or even HP), and weakening to LP before dissipation. The core of the storm contained hail to 2", but was not penetrated. A tornado was observed in the rain-free area as well as a large RFD clear slot northwest of Harmon. Frequent lightning and 40+ MPH inflow winds were encountered as well. The storm had a very striking visual appearance (BWER "vault" and "barber pole" updraft striations) during its LP phase near dusk. The storm was explosively developing on the intersection of the dryline and warm-front boundaries, and was supported by strong winds aloft, an upper trough, a low pressure trough, and surface heating. Documentation was digital stills and HD video. A 2009 Kia Forte was used to chase the storm. A tornado watch was also valid for the area until 10 PM CDT.
6). May 12, 4:30 PM - Observation of a very severe and possibly tornadic thunderstorm near Kingman, Kansas in Kingman County near Highways 400 / 54 and east of Highway 14. The storm was an HP supercell storm, developing in a broken line / cluster of severe storms. The core of the storm, containing hail up to 3" was not penetrated, but hail ahead of the storm to golf-ball size was observed. Heavy rains, 60 MPH winds, and frequent lightning were encountered. A large wall cloud was observed near Kingman before the storm became outflow dominant. The storm was caused by a low pressure system / trough, upper trough, surface heating, and a frontal boundary / gravity-wave interaction. Documentation was still photos and HD video. The chase vehicle was a 2009 Kia Forte. A tornado watch was in effect for the area until 10 PM CDT.
7). May 12, 6:00 PM - Observation and penetration of another very severe thunderstorm near Spivey, Kansas in Kingman County near Highways 42 and 14. The storm was an HP supercell storm, embedded in a broken line / cluster of severe storms. The storm was indirectly penetrated, and a wall cloud / large rain-free base was observed. The storm quickly became outflow dominant, and produced winds to 70 MPH (blowing dust / gustnadoes were observed ahead of the storm gust front). Small hail, torrential rains, and frequent lightning with some close hits were also observed. The storm was caused by a low pressure system / trough, upper trough, surface heating, and a frontal boundary. Documentation was still photos and HD video. The chase vehicle was a 2009 Kia Forte. A tornado watch was in effect for the area until 10 PM CDT.
8). May 12, 11:30 PM - Observation of a very severe thunderstorm from a hotel along Interstate 29 and just east / south of Interstate 435 in the northern sections of Kansas City, Missouri in Platte County. This severe storm was observed from a motel while wrapping up the chase trip, and was an intense blow / squall line segment. Winds over 70 MPH with sideways torrential rains, small hail, and frequent lightning with some close hits were observed. A Mc Donalds sign was damaged across the parking lot during the storm. The storm was caused by a cold front and attendant low-pressure system, upper level low, and warm air advection (low-level jet aloft). Documentation was HD video. A 2009 Kia Forte was used in this storm chase. A tornado watch was also valid for the area until 12 AM CDT.
This concludes the Chase Log for the US Great Plains and Midwest storm chasing trip from May 8 through May 13, 2010. This chase summary includes a total of 8 interceptions with 8 severe thunderstorms observed. As many as 7 tornadoes (5 confirmed) were observed, two of which were very destructive. The main chase vehicle conducting all chases was a 2009 Kia Forte. is TBD. This information was prepared exclusively for the National Weather service and the team of Skywarn storm spotters.
|Here is a picture of an intense multicell cluster of strong and severe storms north of the Florida / Alabama coast while flying from Orlando, Florida to Kansas City, Missouri. The airliner is circumnavigating the severe storms at an altitude of 34,000 feet, providing this great view of the storms (and lightning visible in broad daylight) from the right side of the aircraft (view is to the north).|
|Here is the SAME chase vehicle (a red Kia Forte) I used on my previous chase trip - Same color too - Ready to start chasing and equipment installed.|
|Interesting sign on the eastern part of Greensburg, Kansas. This was a town that was devastated in early May of 2007 from an EF-5 tornado. The entire town was rebuilt with energy efficiency in mind ... And a sense of humor too!|
|Although not a very active chase day, with gloomy and grungy weather most of the day, some fast moving elevated storms managed to show up on radar by early evening on May 9 in extreme north-central Oklahoma near I-35.|
|Here is a picture of the first major supercell storm during its very early stages of initiation. This storm was southwest of Vance, Air Force Base in northern Oklahoma. Beleive it or not, this small and innocent looking storm will eventually grow to a violent supercell and produce multiple tornadoes, including a multi-vortex / wedge tornado later on near the town of Rentrow.|
|This is the same supercell storm's updraft and anvil blow-off as it approached Wakita, Oklahoma and just when it started producing tornadoes. The view is to the southwest and I am about 10 miles WSW of Rentrow.|
|The supercell storm intensifies explosively and this dusty and wide wedge tornado develops to the southwest of Rentrow, Oklahoma. Getting this shot was literally a few minutes before the tornado, moving to the ENE at 60-MPH, would have reached my position.|
|Here is a view of the multi-vortex / wedge tornado just before it beared down on Rentrow, Oklahoma. At least two sub-vortices (smaller tornadoes) can be seen "dancing" within the main tornado circulation.|
|Doppler radar reflectivity image from Vance Air Force Base of the Wakita / Medford supercell during maximum intensity. This is got to be one of the most impressive radar images of a violent supercell I have ever seen. Note the "eye" like feature in the hook "knob" to the lower-left of the supercell!|
|Another violent supercell produces hail over 2 inches in diameter east of Ponca City, Oklahoma along highway 60. This storm also produced tornadoes, one near Pawhuska and another south of Shidler.|
|First view of a tornado on the ground near Pawhuska, Oklahoma off in the distance (image is enhanced, and the tornado silhouette is in the center of the image) from the supercell storm east of Ponca City. The view is to the east.|
|Another tornado from the supercell storm east of Ponca City and south of Shidler, Oklahoma. The view is to the north, and this tornado is NOT the one near Pawhuska above (this supercell had multiple mesocyclones / tornadoes).|
|Another view of the tornado in its later stages and becoming slightly rain-wrapped south of Shidler, Oklahoma.|
|Large wall cloud associated with the older mesocyclone to the west of Shidler, Oklahoma just as the tornado south of that area formed from the new meso.|
|Beautiful line of heavy cumulus, illuminated by the setting hazy sun to the west, associated with the passage of the potent dryline looking east north of Tulsa, Oklahoma.|
|Here are two of the University of Massachusetts DOW (doppler on wheels vehicles) headed down Highway 183 to an initiating LP supercell southwest of Cordell, Oklahoma.|
|This is a picture of an LP supercell storm that has initiated along a bulge in the dryline southwest of Cordell, Oklahoma. The small single updraft has an impressive anvil "crown" spreading overhead. The supercell updraft region is to the lower right. The view is to the west.|
|About an hour later, the LP supercell southwest of Cordell, Oklahoma basically evaporated into nothing. Convective inhibition / lack of forcing was the culprit leading to the demise of the LP storm. The view is northeast.|
|One of the storm chasing tour groups, with storm chaser Brian Morganti, second from right, scratching his head and deciding to go north after the LP storm southwest of Cordell "vanished".|
|Farther north into nortwestern / west-central Oklahoma, a triple point (warm front and dryline intersection) causes initiation of more storms in a focused region. Once developing supercell breaches the "cap" and explosively develops west of Leedey, Oklahoma. The view is to the west.|
|Here is a view of the same supercell undergoing explosive intensification near the dryline / triple-point. The view is to the west and northwest, and was taken a mere 15 minutes after the previous photo above.|
|The supercell storm moves northeast away from west of Leedey and northwest of Vici. This brief tornado was caught from along Highway 60 between Vici and Harmon, Oklahoma. The storm weakend to LP and dissipated about an hour later.|
|Here is the same supercell, still "anchored" on the triple-point, weakening to LP (low precipitation) with a spectacular "barber pole" updraft column at dusk about 10 miles south of Woodward, Oklahoma.|
|Damage to a farm stead near Wakita, Oklahoma. This damage was done by the edges of the circulation of the large tornado that went through the area on May 10.|
|Here are some of the TVN (TornadoVideos.Net) group headed north on I-35 into Wichita, Kansas. The "Dominator" vehicle, with Reed Timmer, is in the lead.|
|Here is a picture of my dewpoint / temperature sensor console, showing a dewpoint of at least 70 degrees F (lower left). Such high dewpoints indicate that moisture from the Caribbean / Gulf of Mexico has advected into the central US.|
|Severe storms, with embeeded HP supercells, explosively develop along a slow-moving cold front west of Wichita, Kansas. The anvil / mammatus can be seen overhead with agitated cumulus in the lower levels.|
|This is the inflow notch into an HP supercell storm, developing in the severe storm cluster, near Kingman, Kansas. A possible funnel is in the center of the picture.|
|The same storm, now northeast of Kingman, Kansas, during evolution to an outflow dominant MCS. The mescocyclone is still present in the dark area in the center of the picture, but cold outflow is undercutting it, precluding the development of any tornadoes.|
|The gust front and shelf cloud of the now outflow-dominant storm northeast of Kingman, Kansas.|
|The storms become outflow dominant, creating a large gust front and a microburst can be seen here kicking up a dust plume. This is near Kingman and west of Wichita, Kansas.|
|This feature, looking east towards Wichita from near Kingman, shows a possible gustnado (swirling dust picked up by a strong gust front).|
|Interesting RFD cleat slot on the "rotating head" cell on the north side of the outflow-dominant bow segment. The view is to the north.|
|A severe thunderstorm, associated with a bow-segment of severe thunderstorms, blasts through the area north of Kansas City near the airport (near my motel) during the late night of May 12. Some signs, including the Mc Donalds sign here, were damaged by the storm, with winds exceeding 70-MPH.|
|First light the next morning on May 13, after severe storms rolled through late at night, north of Kansas City and a damaged Mc Donalds sign.|
