Area Forecast Discussion National Weather Service Peachtree City GA 1055 AM EDT Sat Jul 11 2020
Dry NW flow keeping an abnormally mostly clear summertime regime trending today. Expect daytime radiational heating getting most areas near normal in the low to mid 90s for highs this afternoon. Little change made to forecast as it looks on track. Previous discussion follows .
PREV DISCUSSION. /Issued 742 AM EDT Sat Jul 11 2020/

SHORT TERM /Today through Sunday/ . Drier air mass will set up over the area today, keeping rain chances to a welcomed minimum. Expect generally clear skies through the day and into the overnight period. Cooler morning temperatures are anticipated Sunday as a result of the drier dew points, but the clear skies will promote ample daytime warming, with highs generally 1 to 4 degrees above normal today and Sunday. Even with highs in the mid to upper 90s over middle Georgia, the lower humidity will mitigate any Heat Advisory concerns.
Models continue to show northwest flow ushering in a MCS late Sunday and early Monday morning, which is captured in the increasing pops Sunday afternoon. At this time, SPC does have the northeastern half of the CWA in a Marginal Risk for severe storms given modeled mid- level lapse rates and strong daytime heating. More on this in the extended period discussion.
LONG TERM /Sunday Night through Friday/. A cold front and upper trough/short wave will move to the area Sunday night with an MCS in the NW flow aloft. This will give the possibility for severe thunderstorms, favoring north and west GA.
Except for maybe Monday, the rest of the long term will be highly characterized by diurnal showers and thunderstorms, favoring central GA Monday through Wednesday and the entire area Thursday and Friday.
High temperatures in the 90s for much of the area away from the mountains can be expected. This will allow heat indices in the 95 to 105 degree range through the long term.
AVIATION. 12Z Update . VFR conditions expected through the period, with SKC or FEW high clouds prevailing. Winds will remain on the west side, at 10-12kt during the day, and 8kt or less overnight. Low end gusts are possible in the afternoon.
//ATL Confidence . 12Z Update . High on all elements.

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.
