DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0130 AM CST WED NOV 05 2008
VALID 071200Z - 081200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
SHORT TO MEDIUM RANGE FORECAST GUIDANCE INDICATES THAT THE LARGE-
SCALE POLAR TROUGH WILL BECOME MORE PROGRESSIVE DURING THIS FORECAST
PERIOD...LIKELY SHIFTING EAST OF THE MISSISSIPPI VALLEY... AS THE
NEXT STRONG UPSTREAM JET STREAK APPROACHES THE NORTH CENTRAL PACIFIC
COAST. AS THIS OCCURS...A BROAD FAIRLY DEEP OCCLUDED CYCLONE IS
PROGGED TO MIGRATE ACROSS THE GREAT LAKES...WHILE AN ASSOCIATED COLD
FRONT ADVANCES INTO AND ACROSS THE APPALACHIANS BY 12Z SATURDAY.
HOWEVER...IN THE WAKE OF THE PERSISTENT LOW/MID-LEVEL CYCLONE THAT
IS FINALLY EXPECTED TO SHIFT AWAY FROM THE SOUTHERN/MID ATLANTIC
COAST...MODELS CONTINUE TO SUGGEST LITTLE POTENTIAL FOR APPRECIABLE
DESTABILIZATION. THUS...CONVECTIVE POTENTIAL ACROSS THE EAST...AND
THE REMAINDER OF THE U.S. APPEARS LOW FRIDAY/FRIDAY NIGHT.
..KERR.. 11/05/2008
