NWS STORM PREDICTION CENTER NORMAN OK
0143 AM CST SUN JAN 02 2011
VALID 041200Z - 051200Z
...SYNOPSIS...
ASIDE FROM SHALLOW CONVECTION AND A FEW THUNDERSTORMS BENEATH A
SEWD-DRIFTING UPPER TROUGH ALONG THE SRN CA COAST...THE FOCUS FOR
POTENTIAL CONVECTION WILL BEGIN TO SHIFT DOWNSTREAM INTO PARTS OF
SRN/CNTRL TX. PERSISTENT LOW LEVEL WARM ADVECTION ALONG BACK SIDE
OF A RETREATING SFC ANTICYCLONE WILL ALLOW A PLUME OF MODIFIED GOM
BOUNDARY LAYER MOISTURE TO RETURN TO DEEP SOUTH TX. THOUGH LAPSE
RATES ARE NOT EXPECTED TO BE THAT STEEP IT APPEARS INSTABILITY MAY
PROVE SUFFICIENT FOR ISOLATED THUNDERSTORMS ACROSS THIS
REGION...PRIMARILY DURING THE LATTER HALF OF THE PERIOD. AT THIS
TIME WILL NOT INTRODUCE SEVERE PROBABILITIES DUE TO WEAK INSTABILITY
WITHIN A NONDESCRIPT VERTICAL MOTION FIELD.
