DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1011 AM CST FRI JAN 06 2012
VALID 061630Z - 071200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
A WEAK SRN STREAM SHORTWAVE TROUGH WILL CONTINUE EWD OVER THE NW AND
N CENTRAL GULF OF MEXICO. LOW-LEVEL MOISTURE RETURN IN RESPONSE TO
THIS TROUGH...AND A SEPARATE NRN STREAM WAVE THAT WILL MOVE FROM THE
NRN PLAINS TO THE GREAT LAKES BY TONIGHT...HAS LED TO WEAK
DESTABILIZATION ACROSS SE TX AND W/SW LA. LOW-MIDLEVEL FORCING FOR
ASCENT WILL BE WEAK AT BEST INLAND OVER SE TX/LA THIS
AFTERNOON...BUT MINIMAL CONVECTIVE INHIBITION SUGGESTS THAT ISOLATED
THUNDERSTORMS MAY FORM WITH DAYTIME HEATING IN CLOUD BREAKS.
OTHERWISE...A LOW END TSTM RISK HAS BEEN ADDED FOR THE SE AR/NRN MS
AREA TONIGHT. AN INCREASE IN LOW-LEVEL MOISTURE AND THE APPROACHING
INFLUENCE OF A NRN STREAM TROUGH WILL CONTRIBUTE TO A WAA REGIME
WITH WEAK INSTABILITY ROOTED JUST ABOVE THE SURFACE AFTER ABOUT 06Z.
