Area forecast discussion, Aug 29, 2:43 PM EDT, 1 hour 22 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 243 PM EDT Wed Aug 29 2018 .SHORT TERM /Tonight through Thursday Night/... As deep moisture continues to return to the area, scattered convection will be the rule this afternoon and evening. A couple of strong thunderstorms with brief gusty winds and frequent lightning remain possible, though downdraft CAPE is limited this afternoon. Given weak steering flow, slow-moving/near-stationary thunderstorms will drop locally heavy rainfall. Coverage will quickly diminish in overnight with the loss of heating. Similar to today, scattered convection can be expected on Thursday, primarily during the afternoon and evening hours. Coverage may be enhanced slightly in north Georgia as compared to today given weak upper troughing and a bit more upper support. While a few briefly strong thunderstorms will once again be possible during peak heating, severe thunderstorms are not anticipated. Temperatures will remain near normal through the period. RW .LONG TERM /Friday through Wednesday/... No major changes made to the extended forecast. A weak upper trough will be located just west of the forecast area to start the long term along with weak but deep southerly flow. The upper trough will weaken over the weekend as high pressure aloft builds over the mid-southern Appalachians. This will provide a more easterly upper flow through Tuesday with potential for weak waves to move across. The European has picked up one of these waves and looks to turn it into a tropical low that moves across central FL late Tuesday. For now this will be a watch and see. Otherwise there will be plenty of moisture to fuel highly diurnal showers and storms across the area. Overall forecast instability is rather so so at this point. The GFS is the wettest with rain amounts and the NAM/European less so. Forecast high temperatures will be close to normal throughout the long term and forecast low temperatures will be near to slightly below normal. 01 && .AVIATION... 18Z Update... SCT/BKN cumulus in the VFR range will characterize this afternoon and evening along with scattered shra/tsra. Expect shra/tsra coverage to diminish after sunset. VFR conditions will largely persist with the exception of patchy fog early Thursday morning, especially in CSG/MCN vicinity. Expect additional scattered convection Thursday afternoon. Winds today are light at around 4-6 kts and will diminish to less than 5 kts overnight. Wind direction has been largely variable, though predominant direction is expected to remain SW/SSW through the TAF period at most sites. //ATL Confidence...18Z Update... Medium confidence on wind direction. High confidence on other elements. RW && .PRELIMINARY POINT TEMPS/POPS...
