Area Forecast Discussion National Weather Service Peachtree City GA 243 PM EDT Fri Jul 13 2018 .SHORT TERM /Tonight through Saturday Night/... The Weak cold front that pushed into the area yesterday has all but washed out across central GA today. This front did allow a weak surface high pressure ridge/wedge to build into NE GA last night which brought in the lowered ceilings and cooler temps today. Most areas across North and portions of central GA were running about 5 to 7 deg lower than yesterday because of the overcast clouds. This wedge is expected to continue building into the area through Sat so should see another morning with low clouds again. Showers and thunderstorms have begun to pop across the area and will continue through about 10pm or so. Will see another round of showers and thunderstorms Sat afternoon as well. With this wedge building in the airmass across North GA is fairly stable for this time of year so not expecting much in the way of severe storms today or Sat. This falls right in line with the general thunderstorm risk the entire southeastern U.S. is under through the weekend. 01 .LONG TERM /Sunday through Friday/... Extended period model solutions remain in fairly good agreement, and have continued higher than seasonal pops through day 7 with the region remaining in an unsettled and moist pattern. Models diverge in handling low pressure late next week, but agree enough to keep likely pops headed into next weekend. Previous forecast discussion follows. 31 /Issued 354 AM EDT Fri Jul 13 2018/ Medium-range models are in fairly good agreement through the majority of the Long-Term Forecast period. Region starts out under the eastern edge of the persistent weak, flat, upper ridge with warm temperatures and scattered, mainly diurnal, convection continuing through the end of the weekend. Upper pattern undergoes a significant shift through the upcoming workweek as the upper ridge retreats westward and amplifies with a correspondent deepening trough over the eastern U.S. Sharp frontal boundary enters the region as we head into the middle of the week and sags into the forecast area through the latter half of the week. All-in-all we should see increased precipitation chances and temperatures closer to seasonal normals. 20 && .AVIATION... 18Z Update... Ceilings have finally come up into the VFR range but expecting them to go back down again over night into the MVFR and IFR range through Sat morning. Ceilings will lift again through late Sat morning back into the VFR range. VSBYs should Stay mainly VFR with some brief periods of MVFR readings in and around SHRA/TSRA this afternoon and again Sat. Winds will be mainly out of the East with speeds 10kt or less with some higher gust associated with thunderstorms. //ATL Confidence...18Z Update...
