A FRONTAL SYSTEM OVER NORTHWEST GEORGIA WILL MOVE SOUTHEAST TO THE GEORGIA COAST BY FRIDAY. TROPICAL STORM BONNIE WILL MOVE ONSHORE TO THE FLORIDA PANHANDLE AROUND NOON AND WEAKEN. IT WILL THEN MOVE NORTHEAST UP THE FRONT AS A LOW PRESSURE AREA. .PRIMARY HAZARD...THE PRIMARY HAZARD FROM THE THUNDERSTORMS WILL BE STRONG GUSTY WINDS...HEAVY RAIN AND LIGHTNING. .DISCUSSION... ISOLATED THUNDERSTORMS ARE POSSIBLE TODAY AND TONIGHT. THE THREAT WILL MAINLY STEM FROM THE INTERACTION OF THE MOIST...TROPICAL AIR ASSOCIATED WITH TROPICAL STORM BONNIE AND THE FRONT MOVING ACROSS THE STATE. MOISTURE WILL CONTINUE TO BE ON THE INCREASE IN THE SOUTHERLY FLOW AHEAD OF THE TROPICAL SYSTEM. THIS WILL BE REFLECTED IN DEWPOINTS INCREASING INTO THE 70S ACROSS ALL OF THE STATE EXCEPT BEHIND THE FRONT IN THE EXTREME NORTHWEST CORNER. ALOFT A SHORT WAVE WILL ROTATE THROUGH THE TROUGH THAT WILL MOVE OVER GEORGIA TODAY. AN ASSOCIATED 100 KNOT JET THAT WILL BE MOVING WILL CREATE AN AREA OF UPPER LEVEL DIFFLUENCE IN THE RIGHT REAR EXIT QUADRANT. THIS WILL ENHANCE ANY CONVECTION THAT DEVELOPS BY CREATING UPDRAFT POTENTIAL. A 30 KNOT PLUS LOW LEVEL JET WILL MOVE ACROSS SOUTH GEORGIA TODAY AHEAD OF THE REMAINS OF TROPICAL STORM BONNIE. THIS WILL ENHANCE ANY CONVECTIVE DEVELOPMENT IN CENTRAL AND SOUTH GEORGIA. CAPE WILL BE INCREASING TO AROUND 500 TO 1000 CENTRAL AND SOUTH GEORGIA. LIFTED INDICES WILL DECREASE TO MINUS 2 TO MINUS 3. HELICITIES WILL INCREASE TO AROUND 100. LOW-LEVEL SHEAR ASSOCIATED WITH TROPICAL SYSTEM WILL BE SUFFICIENT TO SUPPORT RISK OF ISOLATED TORNADOES. THE UPPER LEVEL DIFFLUENCE ASSOCIATED WITH THE UPPER JET AND THE LOW LEVEL INFLOW ASSOCIATED WITH THE LOW LEVEL JET PLUS THE REMAINS OF TROPICAL STORM BONNIE MAY COMBINE TO PRODUCE THE NECESSARY CONDITIONS FOR VERY SEVERE THUNDERSTORMS OR POSSIBLY TORNADOES. THE BEST CHANCE OF THUNDERSTORM DEVELOPMENT WILL BE SOUTH AND EAST OF A LINE FROM WASHINGTON TO EATONTON TO COLUMBUS FROM NOON ON...BUT ISOLATED STORMS WILL DEVELOP THIS MORNING. IN ADDITION TO THE ABOVE THREATS...WITH A MOIST..TROPICAL ATMOSPHERE OVER THE STATE...THERE IS THE THREAT OF LOCALIZED FLOODING. PRECIPITABLE WATER IS AT TWO INCHES. THUS ANY SUSTAINED CONVECTIVE ACTIVITY OVER AN AREA SUCH AS TRAINING OR NEARLY STATIONARY THUNDERSTORMS COULD PRODUCE 3 TO 4 INCHES OF RAINFALL IN A RELATIVELY SHORT PERIOD OF TIME. THIS COULD RESULT IN SOME LOCALIZED FLOODING. ALL RESIDENT OF PORTIONS OF NORTH AND CENTRAL GEORGIA ARE URGED TO REMAIN ALERT TO THESE POTENTIALLY DANGEROUS WEATHER DEVELOPMENTS BY LISTENING TO NOAA WEATHER RADIO OR LOCAL MEDIA AND TO TAKE APPROPRIATE PRECAUTIONARY ACTION AS NECESSARY. .SPOTTER INFORMATION STATEMENT... SPOTTER GROUPS AND EMERGENCY MANAGEMENT PERSONNEL SHOULD MONITOR WEATHER CONDITIONS...AND BE READY FOR POSSIBLE ACTIVATION. .DAY TWO THROUGH DAY SEVEN...FRIDAY THROUGH WEDNESDAY. THERE WILL BE A CHANCE OF THUNDERSTORMS FRIDAY...SOME OF THE STORMS MAY BE SEVERE. THUNDERSTORMS ARE ALSO POSSIBLE ON WEDNESDAY.
