SHORT TERM /Today through Sunday/ .
A lingering secondary weak upper impulse is allowing for some isolated light rain/drizzle potential mainly in portions of central GA early this morning, otherwise should transition to NW flow aloft and dry Saturday on tap. Some continued mid level moisture especially in central GA could keep some cloud coverage hanging around today. Should be a fairly pleasant start to the weekend with afternoon highs mostly in the low to mid 60s.
Sfc high center sliding into New England this evening will result in a CAD wedge building in for Sunday across the area. We can expect a shift to cooler temps (about 10 degrees lower than Saturday across north GA), increased easterly gradient winds, and some low level moisture overrunning/isentropic upglide causing increased cloud coverage and some return of afternoon shower potential in parts of the south and west. Ascent and late shower potential could also be aided by a weak upper shortwave.
LONG TERM /Sunday Night through Friday/ .
The long term period begins on Sunday night with a wedge still in place across northeast Georgia. As southwest flow advects moisture over the wedge, chances for showers will continue into the early hours on Monday. Have included slight chance pops for Sunday afternoon with increasing chances Sunday night into Monday afternoon, as the wedge breaks down. A large longwave trough will push a strong cold front towards the area on Tuesday into Wednesday with the arrival of the front during the day on Wednesday. Have included chance pops across much of the area with likely pops across portions of northern Georgia in addition to the mountains. The highest QPF amounts for Monday through Wednesday look to be across far northern Georgia, around 1 to 2 inches with around a half inch or less further south. In addition, models are showing some slight differences on the backside of this system with the GFS showing another shortwave trough developing and crossing the local forecast area late Wednesday into Thursday and the ECMWF, while still showing the shortwave trough, clears precip from the local forecast area by Thursday and takes the trough much further south of the area. Overall, decided to trend on the drier side for pops in this time period, with slight chance to chance pops Wednesday afternoon and clearing across the area on Thursday.
Post frontal passage, high pressure will build into the area at the surface, providing dry weather for Thursday. By Friday, chances for precipitation will increase again as models show a developing surface low in the Gulf moving towards the local forecast area on Friday and Saturday. Although models are showing some differences in timing, have included chance pops for Friday through the early weekend.
High temperatures on Monday and Tuesday will be about 5 to 15 degrees above average in the 60s and 70s, returning to the 40s and 50s through the rest of the extended. Overnight lows Tuesday morning will be very warm in the 50s and 60s, around 20 to 25 degrees above average. Otherwise, lows through the rest of the extended are expected to be in the 30s and 40s.
AVIATION. 18Z Update . BKN VFR cigs in the 050-070 range will prevail at TAF sites through the 21-23z time frame before scattering more appreciably. Borderline VFR/MVFR cigs in the 025-040 range will increase by 09-11z Sunday, though confidence in persistent MVFR cigs is marginal at this time. Winds will remain from the east, initially 5-8kts and increasing to 8-12kts overnight.
//ATL Confidence . 18Z Update . Medium confidence on Sunday morning cigs. High confidence on other elements.

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.
