DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0218 AM CDT THU OCT 27 2011
VALID 291200Z - 301200Z
...SYNOPSIS...
A VERY QUIET SATURDAY WITH RESPECT TO DEEP CONVECTIVE POTENTIAL IS
EXPECTED OVER THE CONUS AS GENERALLY ATTRIBUTABLE TO THE PREVALENCE
OF COOL/STABLE CONDITIONS EAST OF THE ROCKIES. AN UPPER TROUGH WILL
LIKELY SHIFT EAST-NORTHEASTWARD FROM THE APPALACHIANS VICINITY TO
THE WESTERN ATLANTIC...WHILE A SECONDARY SHORTWAVE TROUGH
AMPLIFIES/DIGS SOUTHEASTWARD TOWARD THE NORTHERN PLAINS/UPPER
MIDWEST THROUGH SATURDAY NIGHT. SOME TSTM POTENTIAL...PROBABLY
LIMITED/ISOLATED AT BEST...MAY EXIST ACROSS SOUTH FL ALONG/SOUTH OF
A COLD FRONT. HERE...A RISK FOR SEVERE TSTMS IS UNLIKELY ESPECIALLY
GIVEN THE TREND/FORECAST EXPECTATIONS FOR RINA AS IT APPROACHES THE
FAR SOUTHEAST GULF OF MEXICO/WESTERN CUBA...REFERENCE NHC FORECASTS
FOR THE LATEST DETAILS. ADDITIONALLY...A FEW STRAY LIGHTNING STRIKES
CANNOT BE RULED OUT IN VICINITY OF THE LOWER GREAT LAKES AND/OR
PERHAPS NEAR THE NC OUTER BANKS/ADJACENT OFFSHORE WATERS.
