DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1026 AM CST WED FEB 08 2012

VALID 081630Z - 091200Z

...NO TSTM AREAS FORECAST...

...SE FL COAST TODAY...
PERSISTENT STRATUS WILL BE SLOW TO CLEAR ACROSS SE FL IN A WEAK NLY
FLOW REGIME. THE CLOUDS WILL LIMIT SURFACE HEATING AND
INSTABILITY...AND THERE IS LITTLE FOCUS FOR STORM DEVELOPMENT.
THUS...IT APPEARS THE RISK FOR TSTMS IS TOO MARGINAL TO MAINTAIN AN
OUTLOOK AREA.

...S TX TODAY...
WEAK MIDLEVEL CONVECTION PERSISTS OVER S TX...THOUGH 12Z SOUNDINGS
REVEALED THAT THE BUOYANCY IN THE 700-500 MB LAYER WAS TOO SMALL AND
EQUILIBRIUM LEVEL HEIGHTS WERE TOO LOW/WARM TO SUPPORT MUCH OF A
LIGHTNING RISK. THIS...COMBINED WITH GRADUAL LOW-LEVEL DRYING FROM
N-S AND WEAKENING ASCENT ALL SUGGEST THAT AN OUTLOOK AREA IS
UNNECESSARY.
