SHORT TERM /Today through Friday/ .
Mainly clear skies and dry conditions will prevail through at least the first half of the day today. In addition, high pressure building down the Appalachians will lead to a wedge in portions of north and eastern Georgia. Meanwhile, a shortwave trough currently moving through the southern plains will be approaching the local forecast area later tonight. As moisture is advected into the area from south to north this afternoon and evening, cloud cover will increase in addition to chances for showers and an isolated thunderstorm. Showers are expected to become more widespread by the evening and continue through the overnight hours into Friday. Late tonight, there is a small window where the potential exists for isolated areas of the northeastern mountains to see brief, light freezing rain. At this point, little to no impacts are expected as significant accumulations aren't expected before any freezing rain transitions to all rain.
Friday is expected to be a cloudy and rainy day as showers are expected continue through the afternoon and evening. Mainly showers are expected across the area as instability is limited, but an isolated thunderstorm still isn't out of the question during the day on Friday as the surface low in the Gulf quickly pushes northeast across the area any thunderstorms that do occur may have periods of heavy rainfall and gusty winds. Overall, rainfall amounts from this evening through early Saturday are around 1 to 2 inches across central and eastern Georgia, with totals under an inch across the rest of the area.
With mostly clear skies expected through much of the day today, high temperatures will warm to the 40s across the northeast mountains with 50s elsewhere. Lows overnight tonight will be in the lower 30s in on the mountain ridges with 30s and lower 40s across the rest of the area. As precipitation continues with overcast skies on Friday, high temperatures will be just a couple degrees cooler than today with highs in the 40s across northern Georgia with 50s across central Georgia.
LONG TERM /Friday Night through Wednesday/ .
The primary trough will be pushing into the forecast area Friday night into Saturday morning as the northern Gulf of Mexico surface low lifts northeast across southern/southeastern Georgia. Widespread rainfall can be expected at least through the first half of the night, though coverage should diminish form west to east through Saturday morning as the trough axis swings northeastward. Based on the expected track of the surface low, slight chance thunder was introduced for the southern reaches of the CWA where sufficient instability will be relegated. At this time, the warm sector will likely primarily be limited south and east of the CWA where SPC has introduced a Day 3 Marginal Risk that brushes our far southeast counties. However, an isolated strong thunderstorm with gusty winds cannot be ruled out in these far southeast counties. Rain will largely come to an end for most of the area Saturday with the exception of a few lingering showers possible in far north Georgia.
Sunday will be bring dry and mild conditions as upper flow becomes zonal ahead of the next wave that will be swinging eastward into the Plains by Monday morning. This will lead to the development of the next surface low and associated cold front that will begin to approach the area by Monday. The ECMWF supports earlier precip arrival with showers increasing especially for north Georgia through Monday afternoon and evening. The cold front will push through the area through the day Tuesday with with high PoPs concentrated as the front progresses southeastward. As PWs increase to around/over 1.5", healthy rainfall totals over 1-1.5" are forecast, specifically in north Georgia.
The cold front will sweep east of the area by Tuesday night with surface high pressure bringing dry and cooler conditions midweek next week.
AVIATION. 12Z Update .
VFR cigs or clear skies across northern portions of the area will prevail through much of the daytime hours of the taf cycle with mid level clouds returning to MCN/CSG after about 13Z. MVFR cigs should reach MCN/CSG by 16-20Z and around 22-00Z Friday for atl taf sites. IFR cigs should arrive at MCN/CSG around 3-4Z and at atl metro sites around 5-6Z with potential for LIFR across the area through Friday. Sct SHRA should begin from the south at MCN/CSG near 18/19Z and atl taf sites around 22/23Z and continue with RA through the taf cycle. Winds will be E through the taf cycle around 7-13kts with gusts around 18-20kts through this evening.

I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them. If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
