Area Forecast Discussion National Weather Service Peachtree City GA 255 PM EDT Tue Aug 4 2020 .SHORT TERM /Today through Thursday/... Synoptic setup shows a longwave trough over much of the eastern US with southwesterly winds aloft across the local forecast area. A bit drier across the area today in the mid levels in the wake of Isaias, but there is enough moisture to still allow for pop up showers and thunderstorms already ongoing this afternoon. Biggest difference from yesterday will be coverage and intensity of storms where we should see more typical summertime activity today as strong daytime heating and instability combine to support scattered showers and thunderstorms. In addition with southwesterly flow aloft, weak perturbations moving through the flow may help to enhance storms, leading to chances for some strong to isolated severe storms, like most typical summer days. Fairly similar setup for Wednesday as this afternoon with the same longwave trough and a weak boundary lingering across the area, allowing for showers and thunderstorms in the afternoon and evening. Otherwise, high temperatures for today and Wednesday are expected to be just around seasonal norms with temps in the upper 80s across northern Georgia and getting into the 90s elsewhere. Overnight low temps are expected to be in the 60s and 70s, just a degree or so above average. Reaves .LONG TERM /Thursday Night through Monday/... A deep trough will remain in place over the eastern part of the country with a cold front that's really more of moisture gradient then a temperature boundary. Southerly flow will keep mid level moisture in place fueling afternoon thunderstorms each day this week continuing uninterrupted through the weekend. As the upper level low exits to the northeast, the flow breaks down and we go to a more zonal pattern. The lack of upper level flow and weak steering will allow for the heat to build again going into the weekend. We remain around seasonal in terms of temperatures to start off the long term. With upper 80s and lower 90s across most of the area. Temperatures begin to edge up again going into the weekend with widespread low to mid 90s as the flow breaks down and ridging returns to the area. Heat indices will begin to climb as well with widespread low 100s across the CWA, although cooler conditions are expected at higher elevations. Vaughn && .AVIATION... 18Z Update... VFR cigs across the area are expected to continue into the overnight period. SHRA/TSRA expected today mainly isold in nature and have included a VCSH. Overnight, some patchy fog will be possible but should mostly remain outside of the taf sites. Otherwise slightly increased coverage in SHRA/TSRA possible for Wed afternoon and have included a VCSH at the end of the taf cycle. Winds are currently on the west side but will be light and variable through the rest of the taf cycle. //ATL Confidence...18Z Update... Medium to high on all elements.
