AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 317 PM EDT MON APR 22 2013 .SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/... LATEST SURFACE ANALYSIS SHOWS A COOL DOME OF HIGH PRESSURE ALONG THE MID ATLANTIC COAST...RESULTING IN A GUSTY EASTERLY WIND FLOW TODAY. THE NAM MODEL SEEMS TO HAVE THE BETTER HANDLE ON MID LEVEL MOISTURE SPREADING MAINLY SOUTH AND WEST OF THE FORECAST AREA TONIGHT... THEN SPREADING INTO THE AREA ON TUESDAY AS MID LEVEL FLOW GOES MORE SOUTHERLY BY TUESDAY MORNING. AS A RESULT... COULD SEE SOME MID LEVEL CLOUDINESS SPREAD INTO THE ATLANTA METRO AREA BY LATE TUESDAY MORNING... THEN LIKELY SCATTER BY EARLY EVENING WITH LOSS OF DAYTIME HEATING. MOSTLY CLEAR SKIES AND DIMINISHING WINDS SUPPORT LEANING TOWARD THE COOLER GUIDANCE FOR LOWS TONIGHT... EXCEPT A BLEND AT ATLANTA AND OTHER WARMER SPOTS. THE COOL SURFACE RIDGE WEAKENS AND SETTLES OVER SOUTHEAST GA ON TUESDAY...RESULTING IN A WARMER SOUTHEAST WIND FLOW BY MID TUESDAY AFTERNOON. THIS COUPLED WITH INCREASING CLOUDS SUGGEST A CONTINUED MAV AND MET BLEND FOR HIGHS ON TUESDAY. A SOUTHERLY FLOW FROM SURFACE THROUGH MID LEVELS WILL RESULT IN MUCH WARMER LOWS TUESDAY NIGHT... WITH MOST AREAS IN THE 50S. RAIN CHANCES MIGHT BEGIN TO CREEP INTO FAR NORTHWEST GA LATE TUESDAY NIGHT AS BOTH GFS AND NAM SHOW A COLD FRONT PUSH INTO FAR WEST TN SOMETIME AFTER MIDNIGHT TUESDAY NIGHT. 39 && .LONG TERM /WEDNESDAY THROUGH MONDAY/... GUIDANCE IS STILL WEAKENING THE COLD FRONTAL PASSAGE WEDNESDAY INTO THURSDAY WITH FRONTOGENESIS AND QPF ON THE DECREASE AS IT PUSHES INTO THE AREA. HAVE CONTINUED PREVIOUS FORECAST OF DECREASE IN POPS. WITH DECENT DEEP LAYER SHEAR FORECAST...THOUGH WEAK LOW LEVEL SHEAR AND MARGINAL INSTABILITY OF 500-1000 J/KG...THE SEVERE POTENTIAL REMAINS LOW WITH THIS SYSTEM AS IT LOOKS TO HAVE A WEAKENING TREND IN FORCING FOR ASCENT. AN ISOLATED SEVERE STORM WOULD NOT BE OUT OF THE QUESTION HOWEVER AS STATED IN THE PREVIOUS DISCUSSION BELOW. THERE IS STILL MUCH DISCREPANCY IN THE MODEL SOLUTIONS ON THE INFLUENCE OF A SHORTWAVE FOR THE WEEKEND...THEREFORE HAVE MAINTAINED CURRENT FORECAST OF CHANCE POPS FOR SHOWERS AND THUNDERSTORMS. ALL CONSIDERED...HAVE MAINLY ADJUSTED TEMPS PER RECENT GUIDANCE AND A FEW TWEAKS TO OTHER ELEMENTS. PREVIOUS DISCUSSION FOLLOWS... BAKER PREV DISCUSSION... /ISSUED 400 AM EDT MON APR 22 2013/ .LONG TERM /TUESDAY THROUGH SUNDAY/... WEDGE IN PLACE AT THE BEGINNING OF THE LONG TERM BUT BREAKS DOWN AS NEXT FRONT APPROACHES. GFS AND ECMWF ARE A LITTLE SLOWER TONIGHT WITH BRINGING THE FRONT IN AS COMPARED TO LAST NIGHT. IN ADDITION...THE ECMWF AND SREF ARE SLOWER WITH PUSHING THE FRONT INTO CENTRAL GEORGIA. FOR THE FORECAST...WENT WITH CATEGORICAL/LIKELY POPS FOR WEDNESDAY AFTERNOON AND NIGHT ACROSS NORTH GEORGIA AND THEN CHANCE POPS ACROSS CENTRAL GEORGIA LATE WEDNESDAY NIGHT INTO THURSDAY. NAM AND GFS WEAKEN THE FRONT AS THEY BRING IT INTO CENTRAL GEORGIA WITH BASICALLY NO ACCUMULATED PRECIP. ALTHOUGH WEAKENING TREND IS POSSIBLE...STILL LEFT CHANCE POPS IN THE FORECAST. DECENT INSTABILITY WITH THIS SYSTEM WITH AROUND 1000 J/KG OF MUCAPE ACROSS NORTH GEORGIA. BETTER LOW LEVEL SHEAR THOUGH WITH THE SYSTEM IS LAGGING THE BETTER INSTABILITY. ALTHOUGH WIDESPREAD SEVERE IS NOT EXPECTED...AN ISOLATED SEVERE STORM IS POSSIBLE WITH THE MAIN THREAT BEING DAMAGING WINDS. FRONT CLEARS THE CWA BY THURSDAY EVENING WITH SFC RIDGE BUILDING ACROSS THE AREA. STILL TIMING AND STRENGTH DIFFERENCES WITH SAT/SUN SYSTEM AS A SHORTWAVE AND SFC LOW MOVE ACROSS THE SOUTHEAST. GFS IS STILL THE FASTER AND WEAKER SOLUTION. DESPITE DIFFERENCES...BOTH SOLUTIONS POINT AT PRECIPITATION MID-DAY SATURDAY THROUGH THE REMAINDER OF THE WEEKEND. WILL CONTINUE WITH CHANCE POPS. INSTABILITY SUPPORTS MENTION OF THUNDER...WITH BETTER CHANCES ON SUNDAY WITH HIGHER MUCAPE VALUES /1500 J/KG/. 11 && .AVIATION... 18Z UPDATE... A COOL DOME OF HIGH PRESSURE CONTINUES TO BUILD DOWN THE LEE SIDE OF THE APPALACHIANS... RESULTING IN A GUSTY EASTERLY WIND FLOW. THE RIDGE SHOULD GUIDE MID LEVEL MOISTURE/CIGS SOUTH AND WEST OF ATL OVERNIGHT. MID LEVEL FLOW GOES MORE SOUTHERLY LATER TONIGHT AND SHOULD INCREASE MID LEVEL CIGS BY 15-16Z TUE INTO ATL. WILL SHOW BKN050 BY 15Z TUE WITH WINDS ALSO VEERING FROM EAST TO MORE ESE BY THAT TIME...THE SE LATER TUE AFTN. MID LEVEL CIGS WILL SCT BY 22-23Z TUE. WIND SPEEDS DIMINISH TUE AFTN AS SFC RIDGE SETTLES OVER SE GA. //ATL CONFIDENCE...18Z UPDATE... MEDIUM CONFIDENCE ON CIGS...HIGH CONFIDENCE ALL OTHER ELEMENTS. 39 && .PRELIMINARY POINT TEMPS/POPS...
