NWS STORM PREDICTION CENTER NORMAN OK
1114 PM CST WED NOV 14 2012

VALID 151200Z - 161200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
AN EXPANSIVE SURFACE HIGH WILL AFFECT THE MAJORITY OF THE CONUS FROM
THE ROCKIES TO THE E COAST AS A WEAK UPPER TROUGH MOVES ACROSS THE
CNTRL STATES. EARLY IN THE DAY...A SHORTWAVE TROUGH WILL AFFECT THE
SERN STATES...AND A FEW ISOLATED ELEVATED CONVECTIVE SHOWERS MAY BE
ONGOING. THIS THUNDER THREAT SHOULD GENERALLY WANE DURING THE
AFTERNOON AS THE WAVE MOVES OFFSHORE AND DRY AIR ALOFT OVERSPREADS
THE AREA.

TO THE W...AN UPPER JET AND LOW AMPLITUDE SHORTWAVE TROUGH WILL NOSE
INTO CA AND INTO THE GREAT BASIN LATE. COOLING ALOFT WITH THIS
FEATURE...AS WELL AS MIDLEVEL MOISTURE COULD RESULT IN VERY LIGHT
SHOWERS...AND ONLY AN OUTSIDE CHANCE OF ANY LIGHTNING STRIKES ACROSS
CNTRL CA.
