Area Forecast Discussion National Weather Service Peachtree City GA 723 PM EST Tue Dec 10 2019
. EVENING UPDATE AND 00Z AVIATION DISCUSSION .
Evening and overnight forecasts were updated with latest observation and model trends. Overall, however, the forecast picture hasn't changed much with two bands of scattered light rain showers across the forecast area, with the northern band producing a mix of light rain and snow as temps fall into the low- to mid- 30s. MPing is also showing some reports of sleet earlier today, but as temperatures above 3000 ft continue to cool this evening, we expect this to be much less prevalent as the night goes on. With very warm temperatures in place prior to the frontal, no accumulations of any winter precip are expected outside far north Georgia, and even up there, no more than a 0.25 is forecast outside the highest elevations over 2000ft where locally higher amounts could be possible. For other areas north of the Atlanta perimeter, i.e. areas around Rome and the North and northwest ATL suburbs, some light flurries may mix in with lighter rain as temperatures drop in the early morning before sunrise.
PREV DISCUSSION. /Issued 248 PM EST Tue Dec 10 2019/
SHORT TERM /Tonight through Wednesday Night/ .
Current radar loop shows approaching frontal system pushing showers across the region. This frontal system is expected to continue pushing east through Wednesday afternoon and finally clear the area Wed night. As this front moves through tonight temps are expected to fall and we may see some freezing or frozen precipitation along the back side of the system. Currently we are seeing temps across N GA in the upper 30s to near 40 as this rain moves in. Temps are beginning to fall and will continue to through daybreak into the lower to middle 30s. The only locations that will see temps low enough for a possible rain/snow mix or even all snow will be mainly across N GA especially the NW GA mountains. These areas will see a rain/snow mix before a possible brief transition to all snow on the backside of the system. Overall, accumulations are expected to be light, (A half and inch or less in most locations) so little to no impacts are expected.
Through the afternoon on Wednesday, precipitation is expected to come to an end as drier air moves into the area and high pressure filters in at the surface. As a result, temperatures on Wednesday are expected to be close to but just slightly below seasonal norms, with temps in the 40s across far northern Georgia with 50s across the rest of the area. Wed night lows are expected to get down into the upper 20s across N GA and near 40 across central.
LONG TERM /Thursday through Tuesday/ .
No significant changes made to the general trends through the extended forecast period. Period starts out dry early Thursday, but precipitation begins spreading northeast across the area by late in the day as the next in a series of short waves approaches in the active, progressive pattern across the U.S. Models continue to slowly trend warmer for the onset of the precipitation associated with this system. Model surface wet bulb temperatures at or above 32 degrees across the entire area by 03-09Z. May still see some wintry mix at the onset across the northeast, but it is not looking like we are likely to see any significant accumulations. Some lingering precipitation into early Saturday with a brief break Saturday night into Sunday before the next system sweeps into the area Monday/Tuesday.
AVIATION. 00Z Update .
SHRA will continue across the region through the overnight hours with models showing uncertainty as to exact placement and timing, but higher certainty as to dissipation around 8-12Z tomorrow morning as dry air moves into the area. Any SHRA could bring MVFR CIGS/VSBYs but overall, confidence is increasing that primarily low-VFR could return to all TAF sites by 06Z. Gusty NNW winds expected for all sites except AHN tonight and tomorrow with speeds around 8-15kts and gusts up to 20-25kts, turning out of the NE after 00Z tomorrow night.
//ATL Confidence . 00Z Update .
Low to medium on CIGS through 12-15Z. Medium on Pops through 12-15Z. Medium to High on all other elements through 18Z. High confidence beyond 18Z.

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.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
