DAY 2 CONVECTIVE OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK
1223 AM CST MON NOV 20 2006

VALID 211200Z - 221200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
UPPER TROUGH WILL PERSIST OFF THE WRN CANADA/PAC NW COASTS...WHILE
RIDGE SHIFTS SLOWLY EWD ACROSS THE SWRN AND INTO THE S CENTRAL
CONUS. BETWEEN THESE TWO FEATURES...A BROAD FETCH OF WSWLY FLOW
WILL REMAIN IN PLACE ACROSS THE WRN AND N CENTRAL CONUS...WHILE
SPREADING EWD ACROSS THE GREAT LAKES REGION.  OTHER FEATURE OF
INTEREST ALOFT WILL BE A CLOSED LOW WHICH SHOULD DEEPEN WHILE MOVING
SLOWLY EWD ACROSS FL THROUGH THE END OF THE PERIOD.

...PAC NW...
FAST FETCH OF WSWLY FLOW ALOFT AHEAD OF UPPER TROUGH SHOULD RESULT
IN SHOWERS -- AND PERHAPS A FEW LIGHTNING STRIKES -- ACROSS UPSLOPE
FAVORED AREAS OF THE NWRN CONUS. 

...COASTAL CAROLINAS SWD ALONG THE FL ATLANTIC COAST...
COLD MID-LEVEL TEMPERATURES ASSOCIATED WITH UPPER LOW SHOULD
CONTRIBUTE TO MINIMAL INSTABILITY -- AND ASSOCIATED POTENTIAL FOR
MAINLY OFFSHORE THUNDER.  BEST CHANCE FOR ONSHORE LIGHTNING WILL
LIKELY EXIST ACROSS THE COASTAL CAROLINAS...WHERE ELY FETCH OF
LOW-LEVEL MOISTURE OFF THE GULF STREAM N OF DEVELOPING SURFACE LOW
MAY CONTRIBUTE TO WEAK ELEVATED INSTABILITY.
