Area Forecast Discussion . UPDATED for Aviation National Weather Service Peachtree City GA 138 AM EDT Sat Jul 4 2020
.Have updated the pops across north GA based on radar. Cluster of showers and isolated thunderstorms persist over the far northern counties . but shows some decrease in intensity.
PREV DISCUSSION . /Issued 409 AM EDT Sat Jul 4 2020/
SHORT TERM /Today through Sunday/ .
.Happy Independence Day.
A fairly typical summertime environment and airmass for today with increasing instability that will lead to highly diurnal showers and thunderstorms. The best forecast instability looks to be over portions of north and w central GA and this is where the best chances for showers and thunderstorms will be maximizing this afternoon and diminishing this evening.
The main difference for Sunday is the the models are consistent with increasing deep moisture over S GA. The GFS is the most Gun Ho with bringing that moisture into central GA and the NAM and European are less so. There will be higher pops for central GA in general with the highest S of CSG and MCN. There will still be a highly diurnal nature to the shower and thunderstorm chances.
Forecast high temperatures are running near to as much as 7 degrees above normal across the area today and within 5 degrees of normal for Sunday. Forecast low temperatures are running near to as much as 8 degrees above normal for tonight. Heat indices are running in the 95 to 102 range across much of the area away from the mountains this afternoon and about 92 to 100 for Sunday.
Overall confidence is medium
LONG TERM /Sunday Night through Friday/ .
Fcst period dominated by broad low pressure advecting slowly NEWD off the northern Gulf and with it abundant enhanced moisture setting up and stagnating across the southeast CONUS. Should have high 2 plus inch PWATs across the majority of the CWA Monday through Friday and the GFS is trending even wetter for the end of the week. Have raised pops and am advertising likely to categorical for most of the area through Thursday, then a bit lower for Friday given some model discrepancy on the eastward progression of the low but still decently high chance. Most days with expected numerous to widespread convective coverage maximized in the afternoon and evening with diurnal forcing and given the high PWATs, they will be very efficient precip makers so will need to watch for localized abnormally heavy rainfall and flooding threat. This setup is more of a daily local threat rather than a more organized system over concentrated period so not planning any flood watch products.
Given the increased expected precip/cloud coverage, temps will have a limited diurnal range with below normal highs generally in the 80s and near normal lows.
AVIATION. 182Z Update . VFR conditions are expected to predominate outside of showers and thunderstorms. Potential for after/evening showers and thunderstorms today. Surface winds highly variable less than 10 kts, but generally favoring south southeast.
//ATL Confidence . 18Z Update . Medium to high confidence for 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.
