Wednesday looks insane on the current Models with a 45% hatched for Severe, looking like a dryline play further south and Triple Point further North. At this time due to the early start from DFW Will be playing the Dryline in Central Oklahoma through C Kansas

Interesting MD for Oklahoma, Kansas and Colorado Panhandles - SPC talking of possible 'Cold Core Tornadogenesis' - not often you hear that!:

MESOSCALE DISCUSSION 0735

NWS STORM PREDICTION CENTER NORMAN OK

0151 PM CDT WED MAY 11 2011

AREAS AFFECTED...SERN CO...WRN KS...FAR NWRN OK

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 111851Z - 112015Z

THE THREAT FOR SVR STORMS INCLUDING SUPERCELLS IS EXPECTED TO

DEVELOP BETWEEN 19 AND 21Z.

SFC ANALYSIS AT 18Z DEPICTS A WARM FRONT DRAPED ACROSS NWRN KS INTO

SERN CO EXTENDING TO A SFC LOW 45 S LHX. A COLD FRONT EXTENDS SOUTH

FROM THE LOW INTO THE CNTRL TX PANHANDLE. MEANWHILE...A DRYLINE

INTERSECTS THE COLD FRONT AT A TRIPLE POINT 20 E LHX EXTENDING SEWD

TO 45 ESE GUY AND FARTHER SSE ACROSS THE ERN TX PANHANDLE. THE AIR

MASS BETWEEN THE WARM FRONT AND DRYLINE CONTINUES TO RECOVER IN THE

WAKE OF MORNING CONVECTIVE ACTIVITY...AS DEBRIS CLOUDINESS IS

ERODING IN MANY AREAS YIELDING FULL INSOLATION. THIS HAS ALLOWED

TEMPERATURES TO WARM INTO THE MIDDLE/UPPER 70S IN THE WARM

SECTOR...AMIDST DEWPOINTS IN THE 50S E/NE OF THE DRYLINE. WITHIN

THIS AREA...MODEST LOW-LEVEL MOISTURE COMBINED WITH STEEP LAPSE

RATES /DUE TO THE PROXIMITY OF THE DEEP-LAYER TROUGH CENTERED OVER

THE SRN/CNTRL ROCKIES/ HAS ALLOWED SURFACE-BASED INSTABILITY TO

INCREASE TO AOA 500 J/KG. CONVECTION IS EXPECTED TO DEVELOP DURING

THE NEXT FEW HOURS OVER SWRN KS AND SERN CO AS A MID-LEVEL VORT MAX

SWINGING THROUGH THE ERN PERIPHERY OF THE AFOREMENTIONED TROUGH

IMPACTS THE AREA. EFFECTIVE BULK SHEAR MAGNITUDES AOA 50 KT WILL

YIELD A RISK FOR SUPERCELLS...WITH AN ATTENDANT THREAT FOR DMGG

WINDS AND LARGE HAIL. TORNADOES WILL BE POSSIBLE...ESPECIALLY WHERE

THE LOW-LEVEL FLOW REMAINS RELATIVELY BACKED INVOF THE WARM FRONT

AND TRIPLE POINT. THE THREAT FOR TORNADOES COULD ALSO EVOLVE BETWEEN

THE TRIPLE POINT AND SFC LOW...WHERE THE JUXTAPOSITION OF STRONG

LOW-LEVEL VORTICITY AND BUOYANCY WILL CREATE A FAVORABLE SET-UP FOR

COLD CORE TORNADOGENESIS.

..COHEN.. 05/11/2011

Nice squall line moving through Nern/Central Texas too atm, including DFW area, MD for bow echo with damagine winds out also:

heading north of woodward now hunting down some tops 45 miles to our north glad to hear the chase is going well in DFW

Ian.

The two of us are happily sat in the airport lounge in DFW, with the camera aimed across the runway taking lightning shots and drinking Chardonnay.

Flight is delayed :aggressive:

DUE TO BAD weather, so why did you guys leave DFW area, it's been great and another cell is set to hit us soon, window seat in the lounge camera armed and ready, but will I be sober by the time I board the flight?

Next area of storms is just to the south of us right now

The BBC weather forecast at 10.30 tonight was ramping up the tornado risk later in the week.

Good luck guys. Looks like it could be special. :drinks:

Yep, can see the cell just SW/W of Dodge City, sat shows nice line of cu/cb firing along DL west of Greensburg:

Best place to be today, away from the squall line further E and SE moving through Texas, Oklahoma and eastern Kansas, certaintly for a discrete supercell with chance of a tornado.

Squall line is doing us fine, some great lightning and torrential rain, something we have searched 10days for :whistling:

Next cell has gone to our SE, and the rain has eased.

Watching the cell over Dodge, I'm seeing some characteristic wrap on the radar, fingers crossed for tour 2, hope you get more than we did :cray:
