FXUS62 KFFC 191844 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 244 PM EDT Tue May 19 2026 ...Afternoon Area Forecast Discussion... .KEY MESSAGES... - Warm temperatures continue through with highs in the upper 80s to low 90s. - Increased rain chances return tomorrow through the weekend, especially across northern and western Georgia. && .SHORT TERM... (This afternoon through Wednesday) Issued at 241 PM EDT Tue May 19 2026 Warm and Dry Today: Another pleasant weather afternoon across north and central Georgia with high temperatures climbing to the upper 80s to low 90s, and some fair weather cumulus clouds. A lingering dry airmass with PWAT values under 1" across the area will prevent the cumulus from having much vertical growth. Rain Chances Return Wednesday: Winds turn out of the southwest tonight into Wednesday, bringing moisture back into the region and leading to a return of rain chances. Skies will start off mostly clear, with cumulus building and becoming widespread during the afternoon as PWAT values climb to around 1.2-1.4" in west/northwest GA. This area will likely see isolated to scattered showers and storms developing during the late afternoon and evening as instability peaks. Elsewhere, instability and moisture will be too low to result in anything more than brief isolated showers. Any storms that develop across northwest GA will be garden-variety due to low shear (<20kts) and meager instability (<1000 J/kg), with brief gusty winds and lightning being the primary threats. High temperatures will again climb to the upper 80s to low 90s across the area. && .LONG TERM... (Thursday morning through next Monday) Issued at 241 PM EDT Tue May 19 2026 Not much change in the extended periods. A weakening cold front will have entered the far northern tier by the time the long term period picks up on Thursday. Scattered showers and isolated thunderstorms will linger across north and west Georgia from Wed night with precip spreading further south through the day Thu. As ridging over the Atlantic Coast and west Atlantic continues to flatten, the front will make slow progress southward Thu, eventually stalling north of I-20 amid southwesterly flow aloft. Temperatures and dewpoints will start the morning on Thursday in the mid to upper 60s across the area. High temperatures will be slightly cooler across far north Georgia (in the low to mid 80s) behind the front compared to upper 80s elsewhere across north Georgia and low 90s over central Georgia. Hot and humid conditions will support diurnally enhanced convection, with PoPs of 60-80% for North GA, and 20-40% across central GA. The front will become less defined and begin to lift back northward Friday within southwest mid-level flow along the western periphery of the Atlantic ridge. This southwesterly flow will intensify as a second ridge approaches from the Great Plains, giving the front an additional push away to the north. While this ridge sets up over the eastern CONUS during the weekend, the aforementioned southwesterly flow will continue to spread ample moisture into the forecast area. Temperatures rising into the 80s and low 90s each day along with ample moisture will lead to scattered to numerous diurnal convection each day through the beginning of next week. Coverage of storms will be greatest during the afternoon and evening. At this time, the deepest moisture and highest PWATs across our area will remain across portions of North and West GA. will keep the most consistent heavy rainfall west of Georgia. Some locations across North GA could see 2 to 3 inch 7 day totals. This will be very welcomed precip to help with our current drought situation. && .AVIATION...
