...TX PANHANDLE INTO W CENTRAL TX THIS AFTERNOON/TONIGHT...

WEAK LEE TROUGHING IS EXPECTED TODAY ACROSS W TX BENEATH 20-35 KT

WLY FLOW ALOFT. LARGE SCALE FORCING FOR ASCENT WILL REMAIN RATHER

WEAK OVER W TX IN ASSOCIATION WITH SUBTLE SPEED MAXIMA PROGRESSING

THROUGH SHORTWAVE RIDGING BETWEEN THE UPSTREAM TROUGH IN THE

SUBTROPICAL JET OVER THE LOWER CO RIVER VALLEY...AND THE DOWNSTREAM

TROUGH OVER THE MS VALLEY. STILL...SURFACE HEATING/MIXING AND

LOW-LEVEL CONVERGENCE ALONG THE LEE TROUGH SHOULD ALLOW THE

DEVELOPMENT OF ISOLATED THUNDERSTORMS THIS AFTERNOON. THE STORM

ENVIRONMENT WILL BE CHARACTERIZED BY MLCAPE VALUES OF 1000-1500 J/KG

AND TEMPERATURE-DEW POINT SPREADS GENERALLY AOA 25 F.

MEANWHILE...LOW-MID LEVEL VERTICAL SHEAR WILL BE MARGINALLY

FAVORABLE FOR SUPERCELL STRUCTURES...THOUGH HIGH-LEVEL FLOW WILL BE

RELATIVELY WEAK AND LONG-LIVED SUPERCELLS ARE UNLIKELY. THE PRIMARY

SEVERE THREATS WILL BE ISOLATED LARGE HAIL/DAMAGING OUTFLOW WINDS

GIVEN THE MODEST VERTICAL SHEAR AND LOW-LEVEL MOISTURE...AND THESE

FACTORS ALONG WITH LIMITED STORM COVERAGE WILL LIMIT THE OVERALL

SEVERE THREAT DURING THE AFTERNOON. OVERNIGHT...A FEW ELEVATED

STORMS WITH A MARGINAL HAIL THREAT SHOULD DEVELOP/PERSIST ACROSS NW

TX/WRN OK IN CONJUNCTION WITH WAA WITH A DEVELOPING 30 KT LLJ.

Going to target the South East side of the Caprock today and hope the Magic occurs

For some strange reason you seem to like being east of the Caprock.

At least if they end up heading NE they are guaranteed of a good reception from one hotel at the end of the day's chase! Hope they manage to get a storm like ours that night. :lol:

Wind does seem to be playing havoc with the kick-up competition. I counted about 15 there from Aaron :lazy: :lol: Still a great effort in what looks like a gale force wind.

So, the winner is Paul with 20 plus kick-ups :wacko:

Cells on the Dryline are just not getting Going, looks like the 2 Supes to be on are near Pampa and Elk City today. Essentially unless we haul butt about 150 miles we aint seeing nowt today.

2 Options now, go for it or position for better chance tomorrow, how I hate missed Opportunities!

Not Happy

If you read the SPC - Looks like there could be an Upgrade to a Slight Risk for Supercells so not all bad, some Models showing 4,000jkg of Cape but SPC Going with 1,500 to 2,500jkg of Cape.

Could be a good day in SW Oklahoma or NW Texas today.
