Area forecast discussion, Jun 15, 2:56 PM EDT, 3 hours 56 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 256 PM EDT Fri Jun 15 2018 .SHORT TERM /Tonight through Saturday Night/... Another hot and humid day across north/central GA as a weak boundary is currently draped in the SE. Aloft, very weak flow continues with mid/upper level ridging across much of the south. This will result in widely scattered showers and thunderstorm development this afternoon/early evening. Feel the best coverage for precipitation will be south of I-20 and across the higher terrain in NE GA with slightly better PWATs and instability. With these storms we can expect gusty winds and heavy rain. Given the weak flow in place, the storm motion will be minimal with localized flooding a possibility. Any thunderstorm activity may linger into the evening, but should diminish overnight. Some fog and stratus is possible in the morning, especially in areas that received precipitation this afternoon/evening. Clear and calm conditions expected through most of the overnight. A similar set up for tomorrow, although with the boundary across the region becoming more washed out, we anticipate coverage of storms to be more widespread. Convection will again diminish during the evening hours. Temperatures are expected to be AOA climo through the period. Saturday highs will top out in the upper 80s to low 90s area wide, apart from cooler temperatures in the higher terrain. 26 .LONG TERM /Sunday through Friday/... Looks like we are in a continued pattern of diurnally driven convection through day 7. The extended starts off Sunday with decent afternoon storm potential given a lingering weakening upper low centered across AL. By Sun this low/wave and associated enhanced Gulf moisture is expected to move a bit further Northward across AL and western portions of GA. This will be definitely help to enhance convective potential across the southeastern U.S. The fly in the ointment is still the broad upper ridge which looks to build in from the west and should help to limit overall coverage of showers and storms Sunday through Thursday. This ridge will not completely suppress development as there will be enough daytime heating and available instability to still trigger some isolated to scattered convection. Have generally continued some slight to chance pops for portions of the area through day 7. High temps expected to stay in the low 90s across the area with lows in the 70s through the extended. 01 && .AVIATION... 18Z Update... VFR conditions to start the TAF period as CU decks develop this afternoon around 4Kft. Scattered thunderstorms possible, mainly across MCN/CSG. Winds while light will be out of the east across the northern TAF sites; occasionally becoming westerly. Clear skies overnight and calm conditions. Some fog/stratus possible across CSG Saturday morning. CU development again by late morning around 4Kft with scattered thunderstorms possible area wide for Saturday. Winds will back to the SE. //ATL Confidence...18Z Update... Low confidence on wind direction this afternoon. Medium to High confidence on all elements. 26 && .PRELIMINARY POINT TEMPS/POPS...
