Area Forecast Discussion . Updated for Aviation National Weather Service Peachtree City GA 645 AM EST Mon Nov 30 2020


SHORT TERM /Today through Tuesday/. A short wave will continue crossing the southern Appalachians this morning . moving northeast to the mid Atlantic states. A cold front was moving through the forecast area this morning also . currently pushing east of Athens to Macon with some strong gusts along the boundary. The front was moving steadily and should be out of east central GA before sunrise. There have been a few gusts to over 45kts with the front and some strong gusts in its wake . so a wind advisory has been issued for this morning. The main upper trough will deepen over the southeast through tonight . then push eastward. Wrap around moisture will affect much of north GA through tonight. A mix of rain and snow can be expected today for much of north GA (north of Atlanta to Athens) . with precipitation becoming mainly light snow this evening. Snow accumulations should be around an inch or less except locally higher amounts in the higher elevations and on west and northwest facing slopes.

Temperatures should be falling during the day and overnight lows will range below freezing area wide. Gusty northwest winds will continue tonight into Tuesday with wind chills in the teens and 20s tonight into Tuesday morning.

LONG TERM /Tuesday Night through Sunday/. The extended periods begin with the coldest temps we've seen so far this season. Low temps Tuesday night/Wed Morning will be in the 20s for all of north and central GA. Temps do begin to rebound Wed as they get up into the 50s across the area and then into the 50s and 60s Thu. These temps begin to warm ahead of the next frontal system to approach the area by the end of the work week.

Extended models are in agreement that there will be an end of the week system but that is all they agree on. Timing, location, intensity, and movement of the system are all different from model to model. The only thing I can say for sure is we will be seeing some precip Thu or Fri but exactly when where or how much is out of the question. Will continue with low chance pops for now and Im sure they will have a better handle on things over the next few runs. The one thing to mention though is the GFS has been the most consistent with this system showing a single low pressure center that weakens as it moves east.

01

AVIATION . 12Z Update . IFR conditions will continue to improve in the wake of a cold front. Light showers may be possible at the KATL area taf sites but pops too low to include at this time. Ceilings should remain near MVFR for most of today and into tonight. Winds west to northwest 12 to 15 kts with higher gusts persisting through today . diminishing somewhat overnight.

//ATL Confidence . 12Z Update . Medium to high on all elements.

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.
