AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE PEACHTREE CITY GA 1106 AM EDT WED AUG 20 2014 .UPDATE... DEFINITELY INCREASING CONCERN ABOUT CONVECTIVE POTENTIAL TODAY. TO START...12Z SOUNDING WAS A BIT MORE MOIST THAN EARLIER ANTICIPATED. WHEN MIXED OUT...THE WEAK CAP AT ABOUT 750MB IS EASILY OVERCOME WITH OVER 2700 J/KG CAPE LEFT. ADD TO THIS A DISTURBANCE IN THE NORTHWEST FLOW ALOFT AND AS A RESULT HI-RES GUIDANCE IS DEVELOPING QUITE A BIT OF CONVECTION...AND EVEN HINTING AT A CONVECTIVE COMPLEX MOVING OUT OF TENNESSEE LATE THIS AFTERNOON/EARLY EVENING INTO NORTH GEORGIA. HAVE INCREASED POPS STARTING NOW AS WE ARE ALREADY SEEING LITTLE PINPRICK SHOWERS DEVELOPING AND INCREASING COVERAGE OF TCU. DCAPE VALUES ARE ON THE RISE ACROSS NORTH GEORGIA AS WELL AND SPC HAS EXTENDED THE 5 PERCENT WIND/HAIL THREAT A LITTLE FARTHER SOUTH THAN THE PREVIOUS OUTLOOK HAD. HAVE BEEFED UP WORDING IN HWO TO INDICATE ISOLATED SEVERE POSSIBLE. RIGHT NOW TEMPERATURE TRENDS ARE LOOKING OKAY FOR THE MOST PART. UPDATED PRODUCTS GOING OUT NOW. TDP && .PREV DISCUSSION... /ISSUED 735 AM EDT WED AUG 20 2014/ SHORT TERM /TODAY THROUGH THURSDAY/... /ISSUED AT 340 AM EDT WED AUG 20 2014/ LATEST SATELLITE IR IMAGERY SHOWS AN UPPER LOW SPINNING OVER THE GREAT LAKES REGION WITH SHORT WAVE DISTURBANCE TRAVERSING THE OHIO VALLEY AND SPARKING CONVECTION FROM KENTUCKY NORTHWARD. IN THE WAKE OF THIS DISTURBANCE... SHORT TERM MODELS AGREE ON AN ACTIVE NORTHWEST MID AND UPPER LEVEL FLOW BECOMING ESTABLISHED OVER THE OHIO AND TN VALLEYS BY THIS AFTERNOON AS STRONG HIGH PRESSURE BUILDS INTO THE LOWER MS VALLEY REGION. THE RIDGING INFLUENCE WILL HELP PUSH TEMPERATURES WELL INTO THE LOWER TO MID 90S FOR MOST AREAS TODAY... PRODUCING 2500+ J/KG OF SURFACE BASED CAPE DURING THE AFTERNOON. THIS COUPLED WITH AN ACTIVE NORTHWEST FLOW ACROSS TN AND NORTH GA SUGGEST THE POTENTIAL FOR STORMS TO DEVELOP ACROSS TN DURING DAYTIME HEATING... AND THEN PROPAGATING SOUTHWARD INTO NORTH AND POTENTIALLY CENTRAL GA ALONG OUTFLOWS. THE LOCAL ARW AND WRF HIRES MODELS... ALONG WITH THE NAM12 ARE ALL SUGGESTING THIS POTENTIAL LATER THIS AFTERNOON. ALTHOUGH NOT EXPECTING WIDESPREAD COVERAGE DUE TO SOME UPPER RIDGE INFLUENCE TO THE SOUTH AND SOUTHWEST... A CHANCE OF CONVECTION FOR ALL AREAS IS WARRANTED DURING THE AFTERNOON AND EARLY EVENING HOURS. SOME MID LEVEL DRY AIR IS NOTED ON LATEST SATELLITE WATER VAPOR LOOP TO THE NORTHWEST AND SHOULD SPREAD IN OVER THE AREA THIS AFTERNOON. THIS WOULD SERVE TO ENHANCE STORM DOWNBURST... SUGGESTING THE GREATER STORM THREAT TODAY WILL BE STRONG TO POTENTIALLY DAMAGING WINDS WITH THE STRONGER STORMS. SPC HAS PUSHED A FIVE PERCENT CHANCE OF DAMAGING WINDS INTO FAR NORTH GA TODAY... BUT SUSPECT THIS POTENTIAL WILL EXTEND MUCH FURTHER SOUTH. WILL WORD FOR A FEW STRONG TO POSSIBLY SEVERE STORMS IN THE HAZARDOUS WEATHER OUTLOOK FOR TODAY. NO STORM THREAT TONIGHT WITH LOSS OF DAYTIME HEATING AND CONTINUED RIDGE INFLUENCE. EXPECT SOME PATCHY FOG AND WARMER LOW TEMPS... WITH MOST AREA LOWS HOLDING IN THE 70S. THE THUNDERSTORM THREAT IS EXPECTED TO DIMINISH TO JUST SLIGHT CHANCE AT BEST ON THURSDAY AS THE UPPER RIDGE BUILDS INTO THE STATE FROM THE WEST. THIS WILL PUSH DAYTIME HIGHS WILL INTO THE MID AND UPPER 90S FOR MANY AREAS... AND COULD HELP PUSH SOME HEAT INDEX VALUES ACROSS PARTS OF CENTRAL GA CLOSE TO THE CRITICAL 105 DEGREE MARK THURSDAY AFTERNOON. WILL MONITOR THIS POTENTIAL CLOSELY WITH LATER FORECAST. 39 LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... /ISSUED AT 340 AM EDT WED AUG 20 2014/ MEDIUM RANGE MODELS CONTINUE TO SHOW THE FORECAST AREA DOMINATED BY STRONG UPPER-LEVEL RIDGING THROUGH THE MAJORITY OF THE EXTENDED FORECAST PERIOD. GFS AND ECMWF REMAIN IN GOOD AGREEMENT THROUGH THE WEEKEND BUT DIVERGE SOMEWHAT GOING INTO EARLY NEXT WEEK WITH THE ECMWF FLATTEN THE RIDGE OVER US WHILE THE GFS...ALTHOUGH SHOWING SOME WEAKENING... KEEPS THE RIDGE OVER THE REGION THROUGH WEDNESDAY. STILL...THESE DIFFERENCES DO NOT ALTER THE GENERAL TREND OF HOT AND MOSTLY DRY THROUGH THE WEEKEND WITH MODERATING TEMPERATURES AND INCREASING PRECIPITATION CHANCES EARLY NEXT WEEK...WHICH IS WHAT WE HAVE BEEN CARRYING IN THE EXTENDED FORECAST FOR THE PAST SEVERAL DAYS NOW. WITH THIS IN MIND I DO NOT PLAN ON DEVIATING TOO MUCH FROM PREVIOUS TRENDS IN THE FORECAST GRIDS. THROUGH THE WEEKEND THE GFS/ECMWF KEEP THE CENTER OF THE UPPER RIDGE WEST OF THE STATE WITH THE BEST SUBSIDENCE REMAINING WEST OF US AS WELL. WITH THIS IN MIND I WILL KEEP THE SLIGHT CHANCE POPS INTO THE WEEKEND WITH CHANCE POPS AS WE HEAD INTO THE FIRST HALF OF THE NEW WEEK. 20 AVIATION... 12Z UPDATE... LATEST AREA OBS SHOW LIFR CIGS FROM NEWNAN TO HAMPTON AND GRIFFIN THIS MORNING. THE WESTERLY FLOW IS SPREADING THESE CIGS DUE EAST... AND SATELLITE LOOP ALONG WITH AREA OBS SUGGEST THESE LOW CIGS SHOULD STAY SOUTH OF ATL THIS MORNING. PLAN TO SHOW VFR CONDITIONS THROUGH THE TAF PERIOD AS LATEST TRENDS AND MODEL GUIDANCE SUPPORT THIS. GFS AND NAM MODELS SHOW AN ACTIVE NW FLOW ALOFT THIS AFTERNOON... WHICH WOULD SUPPORT DIURNAL CONVECTION BETWEEN 18-24Z TODAY. WILL SHOW TEMPO -TSRA 19-23Z IN ALL TAFS. LIGHT WEST WINDS THIS MORNING WILL MIX DOWN MORE WNW BY 15Z AND INCREASE TO AROUND 8-10KTS. EXPECT LIGHT WNW WINDS TONIGHT AND NO LOW CIG THREAT. EXPECT SCT MID LEVEL CU AND ONLY AN ISOLATED CONVECTIVE THREAT ON THU AS HIGH PRESSURE BUILDS IN FROM THE WEST. //ATL CONFIDENCE...12Z UPDATE...
