MESOSCALE DISCUSSION 0138
NWS STORM PREDICTION CENTER NORMAN OK
0333 AM CST FRI FEB 21 2014

AREAS AFFECTED...SERN AL...FL PANHANDLE...SWRN THROUGH CNTRL AND
NERN GA

CONCERNING...SEVERE THUNDERSTORM WATCH 21...

VALID 210933Z - 211100Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 21
CONTINUES.

SUMMARY...THREAT FOR MAINLY DAMAGING WIND SHOULD PERSIST NEXT COUPLE
HOURS FROM THE FL PANHANDLE THROUGH SERN AL...SWRN...CNTRL AND NERN
GA.

DISCUSSION...EXTENSIVE SQUALL LINE PERSISTS FROM THE WRN FL
PANHANDLE NEWD THROUGH NRN GA AND IS MOVING EAST AT 30-35 KT.
NUMEROUS BUT MOSTLY UNORGANIZED SEMI-DISCRETE AND CLUSTERS OF STORMS
HAVE DEVELOPED WITHIN ZONE OF WARM ADVECTION AHEAD OF THE MAIN LINE.
WITH TIME SOME OF THE LEADING ACTIVITY COULD EVENTUALLY CONSOLIDATE
INTO THE PRIMARY LINE AS IT DEVELOPS EWD. LATEST OBJECTIVE ANALYSIS
SHOWS A RELATIVE MINIMUM IN MUCAPE FROM ERN GA INTO WRN SC. THIS
SUGGESTS THE STORMS MIGHT EVENTUALLY UNDERGO TEMPORARY WEAKENING
BEFORE RE-STRENGTHENING AFTER COMING UNDER THE INFLUENCE OF
TRAJECTORIES OFF THE GULF STREAM LATER THIS MORNING. THE STRONG /60
KT/ EWD MIGRATING SLY LLJ WILL CONTINUE TO AUGMENT CONVERGENCE ALONG
THE ADVANCING COLD POOL...HELPING TO SUSTAIN ACTIVITY NEXT FEW
HOURS. LIMITING FACTORS FOR A MORE ROBUST SEVERE THREAT INCLUDE
PRESENCE OF NEAR-SFC STABLE LAYER AND WEAK INSTABILITY.
NEVERTHELESS...ISOLATED DAMAGING WIND WILL REMAIN PROBABLE THROUGH
THE EARLY MORNING.
