...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
A LONGWAVE TROUGH...CENTERED OVER CENTRAL CANADA AND THE
NORTH-CENTRAL CONUS...WILL CONTINUE TO SLOWLY SHIFT EASTWARD ON
FRIDAY...WITH A SECONDARY/SOUTHERN PORTION OF THIS TROUGH EXPECTED
TO SPREAD EAST-NORTHEASTWARD OVER THE CENTRAL PLAINS/MIDWEST THROUGH
FRIDAY NIGHT. AS THIS OCCURS...A COLD FRONT WILL CONTINUE TO MOVE
EAST-SOUTHEASTWARD OVER THE GREAT LAKES REGION...TN VALLEY...AND
LOWER MS VALLEY/COASTAL TX.

...FL...
REFERENCE THE NATIONAL HURRICANE CENTER REGARDING THE LATEST
FORECASTS FOR SANDY. PER LATEST NHC TRACK/INTENSITY
GUIDANCE...NORTHERN/EVENTUAL WESTERN PERIPHERAL BANDS WILL LIKELY
IMPACT PARTS OF THE FL PENINSULA ON FRIDAY. WHILE THE FORECAST TRACK
WILL NOT BE CONDUCIVE FOR TORNADO POTENTIAL...SOME CONVECTIVELY
ENHANCED WIND GUSTS MAY BE POSSIBLE WITH ANY INLAND MOVING
LOW-TOPPED TSTMS IN THE PRESENCE OF A VERY STRONG SANDY-PERIPHERAL
WIND FIELD.

...TN VALLEY/LOWER MS VALLEY TO TX...
SOME TSTMS WILL BE POSSIBLE FOR AREAS NEAR A SOUTHEASTWARD MOVING
COLD FRONT FROM THE TN RIVER VALLEY TO TX. A COMBINATION OF WEAK
INSTABILITY/POOR MID LEVEL LAPSE RATES AND/OR WEAKENING MASS
CONVERGENCE SHOULD LIMIT THE LIKELIHOOD/COVERAGE OF TSTMS...WITH
SEVERE TSTMS NOT EXPECTED.
