AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 157 PM EDT THU MAY 3 2012 .PREV DISCUSSION... /ISSUED 745 AM EDT THU MAY 3 2012/ SHORT TERM /TODAY THROUGH FRIDAY/... GULF MOISTURE STREAMING OVER ALABAMA AND MISSISSIPPI WILL SLOWLY WORK ITS WAY EAST TODAY AS THE SURFACE AND UPPER LEVEL RIDGES WEAKEN SLIGHTLY. SHORTWAVE ASSOCIATED WITH THE MOISTURE ACROSS ALABAMA WILL DAMP AS IT MOVES NORTHEAST. OVERALL THE SHORT-TERM MODELS ARE IN REASONABLE AGREEMENT WITH GENERAL TIMING AND LOCATION OF THE MOISTURE...BUT AS WE HAVE SEEN FOR THE PAST COUPLE OF DAYS THE GFS IS OVERDONE WITH CONVECTIVE FEEDBACK AND THUS IS PUTTING MUCH HIGHER QPF AMOUNTS THAN ARE NECESSARY. EXPECT ENOUGH CAPE TODAY...GENERALLY BETWEEN 1000-1500 J/KG...THAT THUNDERSTORMS WILL CERTAINLY BE POSSIBLE. HAVE STARTED THUNDER WORDING AT 15Z AND CARRIED IT THROUGH 06Z FRIDAY. SPC DOES HAVE PORTIONS OF THE AREA IN GENERAL THUNDER FOR TODAY THOUGH THEY DO NOT INCLUDE ANY OF OUR AREA IN THE 5 PERCENT REGION. FRIDAY IS A BIT MORE DIFFICULT BECAUSE YESTERDAY/S 12Z ECMWF REALLY PULLED BACK ON PRECIP...EVEN WITH PLENTIFUL SURFACE MOISTURE AND THE SHORTWAVE MOVING ACROSS THE AREA. HAVE KEPT SLIGHT CHANCE IN FOR FRIDAY...CHANCE NORTH. OVERALL QPF VALUES EXPECTED TO GENERALLY REMAIN BELOW A HALF INCH EXCEPT POSSIBLY IN NORTHWEST GEORGIA IN CLOSER PROXIMITY TO THE SHORTWAVE. WITH INCREASING CLOUD COVER TODAY...TEMPS ESPECIALLY IN WEST AND NORTHWEST GEORGIA WILL BE A LITTLE MORE REASONABLE FOR EARLY MAY... THOUGH THE SOUTHEAST 2/3 OF THE AREA WILL STILL BE WELL ABOVE AVERAGE THIS AFTERNOON. IF CLOUDS MOVE IN EARLIER OR LATER THAN PROGGED TEMPS COULD DEFINITELY BUST. AS IT IS...MAV IS AT LEAST A FEW DEGREES WARMER THAN THE MET ACROSS THE AREA OF INTEREST. HAVE TAKEN A GENERAL BLEND BUT BECAUSE OF THE CONVECTIVE FEEDBACK IN THE GFS...HAVE LEANED SLIGHTLY TOWARD THE COOLER MET. TDP LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... REMNANTS OF GULF SHORTWAVE DRIFT ACROSS GEORGIA BY FRIDAY NIGHT AND THEN OFF THE ATLANTIC COAST. THIS LEAVES THE CWA IN A GENERAL NORTHWEST FLOW ALOFT INTO THE FIRST OF THE WEEK AS SEVERAL IMPULSES SLIDE SOUTHEAST ACROSS THE AREA. UPPER RIDGE BEGINS TO FLATTEN AFTER MONDAY AS A TROUGH MOVES ACROSS SOUTHERN CANADA. SOME DIFFERENCE IN GFS AND ECMWF ON LOCATION OF THIS FEATURE BY MID WEEK AS IT BEGINS TO PUSH A COLD FRONT TOWARD THE STATE. ECMWF SEEMS A BIT FASTER AND FARTHER SOUTH WITH THE FRONT...PUSHING IT INTO THE STATE ON WEDNESDAY. IN GENERAL...THERE SEEMS TO BE ENOUGH MOISTURE AND DYNAMICS ASSOCIATED WITH VARIOUS IMPULSES TO LEAVE CHANCE OR SLIGHT CHANCE IN MOST AREAS THROUGH THE PERIOD. 41 && .AVIATION... 18Z UPDATE... VFR CONDITION WILL PREVAIL INITIALLY...WITH MVFR POSSIBLE AFTER DAYBREAK TOMORROW. WIND WILL CONTINUE TO BE LIGHT AND VARIABLE AHEAD OF A LINE OF SHOWERS AND ISOLATED THUNDERSTORMS TO THE WEST. CONVECTION IS LOW TO SPREAD EAST AND MODELS ARE NOW INDICATING THE IT MAY DISSIPATE BEFORE REACHING MOST OF THE TAF SITES EXCEPT CSG. WINDS WILL GENERALLY BE SW AT 5 KTS OR LESS...ALTHOUGH MAY BRIEFLY BE SE EARLY THIS AFTERNOON. WIND SPEEDS SHOULD INCREASE TOMORROW AFTERNOON TO 5-8KTS. //ATL CONFIDENCE...18Z UPDATE...
