Special weather statement, Nov 1, 10:20 AM CST, 3 hours 48 minutes before
ALZ065>069-FLZ007>019-026>029-034-GAZ121>131-142>148-155>161-011900- HAZARDOUS WEATHER OUTLOOK...UPDATED NATIONAL WEATHER SERVICE TALLAHASSEE FL 1120 AM EST SAT NOV 1 1997 THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EVENING ACROSS EXTREME SOUTHEAST ALABAMA...SOUTHWEST AND SOUTH CENTRAL GEORGIA...THE FLORIDA PANHANDLE...AND BIG BEND. PLENTY OF SUNSHINE ACROSS MOST OF THE AREA THIS MORNING WILL ALLOW TEMPERATURES TO RISE INTO THE UPPER 70S TO LOWER 80S DURING THE EARLY AFTERNOON. AS A RESULT...THE ATMOSPHERE WILL BECOME INCREASINGLY UNSTABLE IN ADVANCE OF A COLD FRONT RAPIDLY APPROACHING FROM THE LOWER MISSISSIPPI VALLEY DURING THE EARLY AFTERNOON. IN ADDITION...WIND SHEAR WILL ALSO INCREASE ACROSS THE REGION. THIS COMBINATION OF INSTABILITY AND WIND SHEAR WILL ALLOW SOME THUNDERSTORMS TO BECOME SEVERE ACROSS THE REGION...DURING THE MID AFTERNOON OVER THE PANHANDLE AND SOUTHEAST ALABAMA AND EXTENDING THROUGH THE EARLY EVENING OVER SOUTH CENTRAL GEORGIA AND THE EASTERN PART OF THE FLORIDA BIG BEND. THE PRIMARY THREATS WILL BE DAMAGING WINDS AND LARGE HAIL. HOWEVER...A FEW TORNADOES ARE POSSIBLE ACROSS SOUTHEAST ALABAMA....SOUTHWEST AND SOUTH CENTRAL GEORGIA...THE FLORIDA PANHANDLE AND BIG BEND...WHERE INSTABILITY WILL BE GREATEST DURING THE MID TO LATE AFTERNOON HOURS. THE THREAT FOR SEVERE WEATHER SHOULD END BY MID TO LATE EVENING AS THE COLD FRONT MOVES ACROSS THE REGION. STORMZ SPOTTERS SHOULD BE PREPARED FOR ACTIVATION THIS AFTERNOON SINCE SEVERE WEATHER WATCHES WILL LIKELY BE ISSUED ACROSS PORTIONS OF THE REGION.
