AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
1031 AM EDT WED MAR 30 2011

.UPDATE...EXPANSIVE AREA OF SHOWERS AND THUNDERSTORMS HAS SPREAD
OVER THE REGION THIS MORNING AS A PASSING SHORTWAVE INTERACTS WITH
THE SYNOPTIC WARM FRONT. THE FRONT CURRENTLY EXTENDS FROM LOW
PRESSURE OVER THE NORTH CENTRAL GULF THROUGH PANAMA CITY AND THEN
INTO SOUTHEAST GEORGIA. THE RAINFALL NORTH OF THE BOUNDARY IS
CURRENTLY INHIBITING ANY FURTHER INLAND PROGRESS OF THE FRONT WITH
THE WARM SECTOR CONFINED SOUTH OF A LINE FROM PANAMA CITY TO
TALLAHASSEE TO VALDOSTA. THIS HAS KEPT THE STRONGER STORMS
CONFINED TO THE COASTAL WATERS THUS FAR THIS MORNING...DESPITE THE
FAVORABLE DEEP LAYER SHEAR AND MID-LEVEL LAPSE RATES.

THROUGH THE REST OF THE AFTERNOON...EXPECT MORE OF THE SAME WITH
THE PRIMARY SEVERE THREAT REMAINING OFFSHORE AND ALONG THE
IMMEDIATE COAST...FOCUSING TOWARDS THE EASTERN BIG BEND LATER THIS
AFTERNOON. EXPECT A BREAK IN THE ACTION SPREADING FROM WEST TO
EAST THIS AFTERNOON BEFORE ADDITIONAL SHOWERS AND THUNDERSTORMS
DEVELOP TONIGHT WITH THE APPROACH OF THE MAIN TROUGH AXIS.

HAVE ADJUSTED THE TEMPERATURES GRIDS ACROSS GEORGIA/ALABAMA THIS
MORNING TO LOWER MAX TEMPS FOR THIS AFTERNOON. ALSO ADJUSTED THE
SEVERE WORDING TO ACCOUNT FOR LATEST THREAT ANALYSIS.

&&

.AVIATION...PREVAILING MVFR/IFR CONDITIONS TODAY IN WIDESPREAD
CONVECTION. RAIN WILL BE HEAVY AT TIMES AND ISOLATED SEVERE
THUNDERSTORMS ARE POSSIBLE. CONDITIONS WILL GRADUALLY IMPROVE
TOWARD THE END OF THE PERIOD AND BEYOND INTO THURSDAY. LOW-LEVEL
WINDS WILL GRADUALLY SHIFT FROM SOUTHEAST TO SOUTHWEST THIS
AFTERNOON...THEN TO NORTHWEST LATER TONIGHT INTO THURSDAY AS THE
FRONT MOVES THROUGH. WINDS WILL BECOME GUSTY IN AND AROUND HEAVY
SHOWERS/STORMS.

&&

.MARINE...MODERATE SOUTHERLY TO SOUTHWESTERLY FLOW WILL CONTINUE
TODAY AHEAD OF A COLD FRONT. STRONG TO OCCASIONALLY SEVERE
THUNDERSTORMS WILL CONTINUE TO PROGRESS ACROSS THE WATERS THROUGH
