Area Forecast Discussion National Weather Service Peachtree City GA 249 PM EST Sat Jan 25 2020
SHORT TERM /Tonight through Sunday Night/. Wrap around clouds associated with the Great Lakes upper low continue to drift across north Ga Satellite showing some thinning. but patches of stratocu may linger into the late afternoon or early evening across the far north. The flow becomes more westerly overnight into early Sunday . but moisture returns rapidly into GA late Sunday afternoon ahead of the next system. A lower MS Valley upper trough and surface low tracking across the northern Gulf will spread showers back over the forecast area . with pops increasing into the overnight hours Sunday. At this time no winter precipitation is expected as temperatures should remain above freezing Also. the air mass remains too stable to mention thunder.
LONG TERM /Monday through Saturday/. No major changes made to the extended forecast. Cool/wet pattern still expected for the bulk of the long term period. Cutoff low over NW Mexico now progged for Thurs so forecast uncertainty expected to increase only very late in the period.
First round of rain Sun night/Mon with broad shortwave moving through in strong mean flow. Not a ton of lift but enough for light rain with up to 0.10 inch rainfall. Temps in far NE GA remain above 37F so no mention of rain/snow mix attm. Will need to monitor this in later forecasts.
NW flow for 36-48hrs before next more compact wave moves east along strong southern branch flow. There is some indication of an out-of-phase, fast moving wave in the northern branch that should be far enough ahead to set up cold air damming pattern favorable for light mixed precip in far northeast Wed morning. Have mention of rain/snow mix in higher elevations. QPF overall with this wave very low as low levels will be dry. Could just be sprinkles.
A relatively brief period of sunny weather expected Thurs before next wave from ejected cutoff low arrives. Timing and intensity quite a bit different between model guidance, but should be the strongest of the three with heavier rain. Still no evidence of any instability or a threat of severe storms with this system. Most likely timing is Friday. Again, some indication that temp in far northeast may be cold enough for some light mixed precip so continued with rain/snow mix in higher elevations for Fri morning.
AVIATION. 18Z Update . MVFR stratocu lingering this afternoon. Satellite showing some thinning but patches of clouds could hold on over the KATL taf sites until 22z.

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.
