877 FXUS62 KFFC 161737 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 137 PM EDT Tue Jul 16 2024 ...New 18Z Aviation Discussion... .SHORT TERM... (Today through Wednesday) Issued at 326 AM EDT Tue Jul 16 2024 Temps are running about 3-7F degrees cooler than this time last night thanks to the storms that covered a good portion of north and central GA yesterday afternoon/evening. The upper level pattern remains rather unchanged in the last 24-hours with moisture and remnant boundaries re-circulating around a nearly stationary low-to- mid lvl high along the AL/FL Gulf coast. Daytime heating will trigger another round of showers/storms this afternoon within moist/unstable airmass. Max temps will be a few degrees lower than Monday but dewpts are up a few degrees resulting in fairly similar peak Heat Index values today in the 98-105F range with isolated values as high as 108F possible. By tomorrow (Wednesday), we begin to see the affects of a deeper longwave upr trough digging across the Upper Midwest/Great Lakes regions. Better synoptic-scale forcing enters the area as remnant low-lvl cold pools/boundaries from upstream MCS`s become more of a focus for convection across north/central GA. Overall severe threat remains low but cannot rule out isolated stronger wind gusts as MUCAPE gets up into the 1500-2000 J/KG range and low to mid-lvl winds increase ahead of upr trough. DJN.83 && .LONG TERM... (Wednesday night through Monday) Issued at 326 AM EDT Tue Jul 16 2024 At a glance: -We begin our much needed heat break. -Showers and thunderstorms will be likely every afternoon. The long term kicks off on Wednesday and temps are still expected to climb into the mid 90s, but by Thursday the front will have worked it`s way far enough south that we should see temps fall back into the low 90s and upper 80s; with some high 70s in our mountain areas. Drought conditions may get some relief as we head into this rainy period. Precipitable waters will range from the 2 to 2.5 inch range Wed through Fri so depending on where the strongest bands set up, we could see some significant rain totals. 7 day QPF totals are in the 2 inch range with locally higher amounts expected for isolated areas. Widespread severe weather is not expected, but a few afternoon storms could warrant a SVR warning with winds being the primary concern. Given MU CAPE values in the vicinity of 2000+ J/KG most of our afternoon convection will likely have strong winds, periods of heavy rain, and frequent lightning. Vaughn && .AVIATION... (18Z TAFS) Issued at 131 PM EDT Tue Jul 16 2024 Broken line of thunderstorms moving east may affect the ATL metro in the next hour. An abundant cu field is becoming SCT- BKN at 4kft currently and expecting scattered convection to pop up across the area in the next hour or two. Winds stay from the west through the TAF period. Thunderstorms are expected to be more widespread in coverage tomorrow beginning ~17z and lasting through 23-00z. //ATL Confidence...18Z Update... Medium confidence on TS coverage and timing.
