Area Forecast Discussion . UPDATED National Weather Service Peachtree City GA 923 PM EST Mon Dec 9 2019
UPDATE. No changes to the forecast for the overnight.
PREV DISCUSSION . /Issued 600 PM EST Mon Dec 9 2019/
SHORT TERM /Tonight through Tuesday Night/ .
Current satellite loop shows low to mid level clouds lifting and scattering out from SW to NE. The wedge is still keeping the clouds over NE GA but it is diminishing and so are the clouds. There are still a few light showers and areas of drizzle across the state as well but they are diminishing also. Moist Southwesterly flow is setting up ahead of the approaching/developing frontal system now over the Mid MS river valley. This frontal system will bring rain to NW GA beginning tonight . then spreading rain across the rest of the state through Tuesday Night. There is a little instability associated with this system for Tuesday afternoon mainly across west central Georgia, but being so low have just included chances for rain . no thunder. As this system begins to exit our area Tuesday night. We may see some freezing or frozen precipitation mainly across North GA. Right now we are only looking at accumulations of up to an inch or less with the highest accumulation mainly on surfaces above 2000ft.
Lows tonight expected in the upper 40s to near 60 with highs Tuesday generally in the 60s and 70s. Lows Tuesday night will get down into the lower 30s across N GA with lows in the 40s across central portions of the state.
LONG TERM /Wednesday through Monday/ .
Models continue in generally good agreement on the larger scale patterns through the majority of the forecast period. Some noticeable divergence beginning to develop concerning the speed and strength of the long wave trough at the end of the period.
Period starts as the precipitation is exiting with the short wave that is approaching the region tonight. Still some uncertainty concerning how well the back edge of the precipitation will line up with the deeper cold air and how much lingering precipitation we will see going into Wednesday morning. Still looks like any wintry mix in the far north will be ending quickly as the precipitation pushes east.
Next short wave digs into the mid/lower Mississippi Valley late Thursday through Friday. May have enough lingering cold air in the far northeast for the precipitation to start out as a light mix across that area, but temperatures are forecast to rebound nicely Friday and any accumulations are still looking to be limited at this time. Precipitation chances stretch into the first half of the weekend with drying for the latter half. Fairly progressive upper pattern brings another chance for precipitation into the region early next week.
AVIATION . Increasing potential for MVFR-IFR ceilings to develop overnight, improving to MVFR-VFR Tuesday. Some MVFR vsbys possible. Increasing rain chances later tonight and Tuesday. Surface winds varying E-SSW less than 10 kts, becoming SW then WNW during the day Tuesday 10-15 kts with some gusts.
//ATL Confidence . 00Z Update . Low to medium confidence for all elements. Once the winds go to the west side then medium to high confidence for winds.

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.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. 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.
