Area forecast discussion, May 29, 3:19 PM EDT, 3 hours 30 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 319 PM EDT SUN MAY 29 2016 .SHORT TERM /Tonight through Monday Night/... Tropical Depression Bonnie is now inland, just northwest of Charleston SC. Light rain and associated cirrus shield has eroded across east-central GA this afternoon, but has left a fairly well- defined north-south oriented differential heating zone across the area. Within this zone...low level convergence helping to generate and support scattered showers, especially between Covington and Macon. Expect this to continue through the afternoon with ongoing surface heating. Not expecting any major impacts with convection aside from occasional cloud to ground lightning, locally heavy rain, and brief wind gusts to 35 mph. Tonight...Loss of heating should taper any convection across the area as TD Bonnie meanders north/east, just inland along the SC coast. Temps will gradually cool back into the 70s this evening with overnight lows similar to this morning /generally in the 60s/. Memorial Day...the area remains sandwiched between "Bonnie" and a weak upr ridge extending from the Lower MS Valley to the Ohio Valley. Daytime heating and weak energy rotating south/west from the upr low associated with Bonnie could spark a few afternoon showers/storms, but most areas will remain dry and warm. Abundant sunshine expected for the first part of the day will allow temps to warm quickly into the lwr-mid 80s by midday. DJN.83 .LONG TERM /Tuesday through Sunday/... Extended forecast trends look good with best rain chances Friday and through the weekend. Have made minor adjustments to late extended QPF (Day 7) to account for latest model trends. Have also gone ahead and drawn far north Georgia in the likely pop region for Friday afternoon which now has better neighbor consistency. Model uncertainty for Day 6 (Friday) is relatively low, and confidence is fairly high likely pops are necessary for the pattern. Otherwise only small adjustments were made to temperatures and dew points. 31 && .AVIATION... 18Z Update...Mainly VFR conditions expected to prevail through tomorrow /Monday/ morning at all TAF sites in north/central GA. Watching a few -SHRA develop between Covington and Macon, moving south. Could influnce MCN in the next few hours, hence the TEMPO. Otherwise, pop-up showers/isold tstms expected through sunset this evening. Outflow from rain shield associated with TD Bonnie, plus developing convection will likely swing winds around to NE over ATL between 22-02z. Winds expected to shift back around to NW tomorrow mrng. Few-Sct cumulus develop by 17z but little to no convection expected. //ATL Confidence...18Z Update... Medium on wind direction. High all other elements. DJN.83 && .PRELIMINARY POINT TEMPS/POPS...
