SLIGHTLY COOLER 500 MB TEMPS AND MORE SFC HEATING SHOULD ALLOW SE GA TO FILL IN WITH SHOWERS AND STORMS OVER THE NEXT COUPLE OF HOURS. GREATEST THREATS FROM THESE STORMS ARE GUSTY WINDS TO NEAR 50 MPH...VERY HEAVY RAINFALL...AND FREQUENT TO CONTINUOUS LIGHTNING. RAINFALL THREAT APPEARS TO BE INCREASING AS STORMS REACH THE COAST AND ENCOUNTER S TO SE LOW-LEVEL WINDS.
