AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 230 PM EDT THU APR 19 2012 .UPDATE... /ISSUED 1142 AM EDT THU APR 19 2012/ HAVE ADJUSTED HIGH TEMPERATURES FOR TODAY. AMPLE CLOUD COVER HAS HINDERED INSOLATION THIS MORNING...AND TEMPERATURES ARE GENERALLY STILL IN THE 50S TO LOW 60S. AS A RESULT...HAVE LOWERED AFTERNOON HIGHS...AND ADJUSTED THE HOURLY TEMPS. HAVE ALSO MADE MINOR CHANGES TO DEW POINTS. ALL OTHER CHANGES WILL OCCUR WITH THE AFTERNOON PACKAGE. 31 && .UPDATE... /ISSUED 929 AM EDT THU APR 19 2012/ HAVE MADE A FEW ADJUSTMENTS TO THE GRIDS THIS MORNING. BASED ON THE LATEST TRENDS...HAVE ADJUSTED HOURLY TEMPERATURES AND DEWPOINTS. HAVE ADDED SPRINKLES TO THE FORECAST FOR AREAS GENERALLY SOUTH OF I-20 TO ACCOUNT FOR CURRENT RADAR TRENDS. HAVE UPDATED HWO TO REFLECT SLIGHT CHANCE THUNDER ACROSS THE FAR SE CWA THIS AFTERNOON AS PER FORECAST. ALTHOUGH BEST MOISTURE AND INSTABILITY REMAINS JUST SOUTH AND EAST OF THE CWA BORDER...ENOUGH OF IT DOES NOSE INTO THE SE CORNER FOR POSSIBLE ISOLATED THUNDERSTORMS THIS AFTERNOON. WILL MAKE ADDITIONAL FORECAST CHANGES AS NEEDED THROUGH THE MORNING...ALTHOUGH NO ADDITIONAL UPDATES ARE ANTICIPATED AT THIS TIME. 31 && .SHORT TERM /TODAY THROUGH FRIDAY NIGHT/... /ISSUED 410 AM EDT THU APR 19 2012/ CURRENT SATELLITE LOOP SHOWS SOME SCATTERED SHOWERS OVER CENTRAL GEORGIA THIS MORNING. THESE SHOWERS ARE ROTATING NORTHWARD AROUND THE SURFACE LOW CENTERED OVER THE FL PANHANDLE. THESE SHOWERS ARE LIGHT WITH NO THUNDERSTORMS PRESENT. EXPECTING THESE SHOWERS TO DISSIPATE BEFORE SUNRISE AS THE LOW CENTER CONTINUES TO MOVE EAST MAIN FRONTAL SYSTEM HAS MOVES SOUTH AND EAST OF THE CWA AND SHOULD BE COMPLETELY OFFSHORE BY 14-18Z TODAY. THIS WILL ALSO KEEP THE LARGE MOISTURE PLUME EXTENDING FROM THE NEW ENGLAND STATES...DOWN TO THE YUCATAN PENINSULA OFF THE EASTERN SEABOARD AS WELL. THERE WILL STILL BE SOME RESIDUAL MOISTURE ACROSS THE STAT THROUGH THE SHORT TERM SO HAVE KEPT IN A SLIGHT CHANCE FRO PORTIONS OF EAST GEORGIA THROUGH THE SHORT TERM. INSTABILITY INDICES SPIKE EVERYDAY AT 18Z SO HAVE ALSO KEPT THUNDERS IN THE FORECAST AS WELL. TEMPS WILL BE NEAR SEASONAL NORMS TODAY WITH SLIGHTLY ABOVE FRIDAY AND SAT. 01 .LONG TERM /SATURDAY THROUGH WEDNESDAY/... /ISSUED 410 AM EDT THU APR 19 2012/ CHALLENGING EXTENDED PERIOD IN STORE AS WE SEE A SIGNIFICANT STORM SYSTEM DEVELOP OVER THE DEEP SOUTH WITH SIGNIFICANT DIFFERENCES AMONG THE MODELS. LOOKING AT THE UPPER LEVEL FEATURES...ACTUALLY SEE GOOD SIMILARITIES IN THE GFS AND ECMWF WITH A CLOSED 500MB LOW DIVING SOUTH OF THE FLORIDA PANHANDLE LATE SATURDAY BUT THIS IS WHERE SIMILARITIES END. MAIN DIFFERENCE BETWEEN THE MODELS WHICH IS A SIGNIFICANT ONE IS HOW MUCH MOISTURE IS TRANSPORTED NORTHWARD AS THE ECMWF IS MUCH WETTER. THIS LOOKS TO BE THE RESULT OF A MORE DIFFLUENT PATTERN AT 200 MB FOR THE ECMWF VERSUS THE GFS. STILL NOT A GOOD FEEL ONE WAY OR THE OTHER AND PLAN TO TEMPER CURRENT POPS A BIT FOR THE NORTH BUT KEEP HIGHEST CHANCES FOR SOUTHERN ZONES. IF GFS AND ENSEMBLE MEMBERS VERIFY...THERE WOULD BE VERY LITTLE PRECIP ACROSS THE AREA FOR THE WEEKEND BUT NOT READY TO BITE OFF COMPLETELY YET GIVEN OTHER LONG RANGE MODEL DIFFERENCES. SYSTEM CLEARS OUT LATE IN THE WEEKEND WITH A DRY REMAINDER OF THE EXTENDED PERIOD ANTICIPATED. DEESE && .AVIATION... 18Z UPDATE...

ISOLATED THUNDERSTORMS POSSIBLE ACROSS PORTIONS OF EASTERN AND CENTRAL GEORGIA. .SYNOPSIS... A SURFACE LOW WILL CONTINUE TO MOVE EAST OFF THE CAROLINA COAST THROUGH THIS AFTERNOON...ALLOWING WEAK HIGH PRESSURE TO BUILD IN FROM THE WEST. THIS SETUP WILL ALLOW THUNDERSTORM DEVELOPMENT IN PORTIONS OF EASTERN AND CENTRAL GEORGIA. .PRIMARY HAZARDS... THE PRIMARY HAZARDS WILL BE LIGHTNING...GUSTY WINDS TO 30 MPH...AND SMALL HAIL. .DISCUSSION... WITH MOISTURE REMAINING ACROSS SOUTHEAST GEORGIA...LOW PRESSURE EXITING OFF THE CAROLINA COAST WILL TRIGGER THUNDERSTORM DEVELOPMENT THIS AFTERNOON. ALTHOUGH MUCH OF THE CONVECTION IS EXPECTED CLOSER TO THE GEORGIA COAST AND OVER THE CAROLINAS...THE ENVIRONMENT OVER PORTIONS OF EASTERN AND CENTRAL GEORGIA COULD SUPPORT ISOLATED THUNDERSTORMS. CAPE VALUES IN THE 700-900 J/KG RANGE...AND LIFTED INDEX VALUES BELOW -2 WILL SUPPORT ISOLATED CONVECTION. IN GENERAL...ACTIVITY SHOULD BE SOUTH AND EAST OF A LINE FROM HAWKINSVILLE TO WARRENTON. AT THIS TIME...ANY DEVELOPING THUNDERSTORMS SHOULD REMAIN BELOW SEVERE LIMITS. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY... THERE IS A CHANCE OF THUNDERSTORMS ACROSS PORTIONS NORTH GEORGIA ON FRIDAY. A MORE ORGANIZED SYSTEM WILL TAKE SHAPE OVER THE WEEKEND AS LOW PRESSURE DEVELOPS ALONG THE NORTHERN GULF COAST. BASED ON THIS POSITION...ALTHOUGH THUNDERSTORMS WILL BE POSSIBLE OVER THE AREA...THE STRENGTH OF THE STORMS SHOULD BE LIMITED IF CURRENT TRENDS CONTINUE. NO HAZARDOUS WEATHER IS ANTICIPATED MONDAY THROUGH WEDNESDAY OF NEXT WEEK. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION IS NOT EXPECTED THROUGH TONIGHT.
