368 FXUS62 KFFC 201948 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 248 PM EST Thu Nov 20 2025 ...Afternoon Area Forecast Discussion... .KEY MESSAGES... Updated at 233 PM EST Thu Nov 20 2025 - Above-normal temperatures will persist through the middle of next week. A few record highs may be met or broken over the coming days at our four main climate sites. - A few rounds of rainfall and thunderstorms are expected through next week, but it is unlikely that much drought improvement will occur. && .SHORT TERM... (This afternoon through Friday) Issued at 233 PM EST Thu Nov 20 2025 Light to moderate rain and embedded thunderstorms are occurring across the Mid-South along a stationary front and ahead of a shortwave trough slowly lifting out of the Four Corners region. As this shortwave exits to the northeast and another shortwave drops south along the California coast tomorrow (Friday), the ridge over much of the Southeast will be reinforced. The result will be continued warmer-than-average temperatures (by as much as 15-17 degrees for highs and 22-24 degrees for lows). Now back to the rain occurring across the Mid-South -- this activity will shift eastward through the rest of the afternoon, pushing across far north Georgia this evening and overnight. Embedded storms will remain a possibility, but severe storms are not expected given very limited instability. Forecast soundings and model guidance suggest areas of fog (and low clouds) overnight into tomorrow morning, but current thinking is that coverage will be less widespread than last night/this morning`s fog and low clouds, perhaps due at least in part to increased mid-/upper- level cloud cover. Another push of rain and isolated storms is expected Friday afternoon into Saturday, with activity spreading in from northwest to southeast. Again, severe storms are not expected given overall limited instability. That said, an uptick in storm coverage (and perhaps a couple strong storms) will be possible Friday overnight into early Saturday morning as hi-res guidance shows CAPE increasing ahead of a surface low that will be tracking across the Tennessee River Valley. Rainfall from this evening through early Saturday morning is forecast to total as little as a trace to as much as 0.75 inch. Portions of central Georgia will have to wait until the systems talked about in the long term discussion to get any rainfall. && .LONG TERM... (Saturday morning through next Wednesday) Issued at 233 PM EST Thu Nov 20 2025 The extended period starts off with the frontal boundary that moved into the area Friday night laying across central GA. We will still see some light showers and isolated thunderstorms Sat but a drier airmass begins to push into NW GA shortly after sunrise. The actual front moves into S GA/N FL by Sat afternoon but there will still be some lingering showers across central GA. This drier airmass pushes into the state from NW to SE with decreasing clouds across the area Sat. Will see some cloud cover across N GA Sat night with some backside moisture sweeping through the area but not expecting any precipitation High pressure centered over western KY/TN builds slowly SE Sun into Mon keeping things warm and dry through Mon evening. The ridge center moves NE into the New England states through Monday night allowing the next frontal boundary to push into the area. The next frontal boundary begins developing across NM/TX Sunday evening with its deepening closed low center over western KS by daybreak Mon. The low center continues moving NE into the western great lake states by early Tue morning. Its associated cold front begins pushing showers into North GA Monday night with the frontal boundary swinging slowly through the region Tue/Wed. This front does look like it should clear the CWA by Thu morning. && .AVIATION... (18Z TAFS) Issued at 107 PM EST Thu Nov 20 2025 CIGs have gradually improved through the morning, with mainly VFR CONDs expected through the remainder of the afternoon and evening. CIGs and VIS will be forecast challenges overnight into tomorrow (Friday) morning, as at this time, coverage of low clouds and reduced VIS looks to be lower/patchier than what occurred this morning. Given this uncertainty, have FEW/SCT IFR/MVFR clouds and reduced VIS in most of the TAFs overnight into tomorrow morning. Winds will be light out of the SW at ATL today, becoming light/VRB to calm this evening. //ATL Confidence...18Z Update... Low confidence on coverage/evolution of low clouds and reduced VIS overnight into tomorrow morning. Martin && .PRELIMINARY POINT TEMPS/POPS...
