NWS STORM PREDICTION CENTER NORMAN OK

AREAS AFFECTED...SERN LA/FAR SRN MS/FAR SWRN AL

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 130103Z - 130200Z

ISOLATED STORMS WITH STRONG GUSTY WINDS SHOULD BE THE PRIMARY THREAT
THROUGH 03Z ACROSS FAR SERN LA TO FAR SWRN AL. ACTIVITY WILL EITHER
MOVE OFF THE LA COAST BY THAT TIME OR WEAKEN EWD INTO STABILIZING
AIR MASS ACROSS SWRN AL.

THUNDERSTORMS CONTINUE TO DEVELOP ALONG TWO COLD POOL OUTFLOW
BOUNDARIES WHICH CURRENTLY EXTENDED FROM SWRN AL SWWD TO NRN
JEFFERSON PARISH LA THEN WWD TO NEAR LCH.  ENHANCED LOW-LEVEL
CONVERGENCE ALONG THESE SSEWD MOVING BOUNDARIES IS AIDING IN
SUSTAINED CONVECTIVE DEVELOPMENT ALONG AND JUST N OF OUTFLOW
BOUNDARIES.  AIR MASS ALONG AND SOUTH OF THE ACTIVITY IS STABILIZING
WITH TIME...BUT REMAINS MODERATELY UNSTABLE TO SUPPORT SOME STORM
ORGANIZATION.  MOIST LOW-MID LEVEL ADIABATIC LAPSE RATES SHOULD
SUPPORT WET MICROBURSTS...THOUGH GENERALLY WEAK LOW-MID LEVEL WINDS
SHOULD LIMIT THE WIND GUSTS TO MARGINALLY SEVERE ALONG 15-20 KT
MOVING OUTFLOW BOUNDARIES.
