369 FXUS62 KGSP 111724 AFDGSP Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 124 PM EDT Fri Jul 11 2025 .SYNOPSIS... Active summertime weather will continue thru the weekend with scattered to numerous showers and thunderstorms each day. High temperatures will increase each day through Monday, trending back to around normal for the middle of next week behind a weak cold front. && .NEAR TERM /THROUGH SATURDAY/... As of 130 PM EDT Friday: Mountain deep convection has been struggling to strengthen early this afternoon, perhaps thanks to the drying as per the wv loops or the developing weak upper anticyclonic flow. Nonetheless, the sensible wx into the early evening will feature scattered, mainly garden variety storms developing into the Piedmont. Fair weather is on tap for later tonight as a weak westerly flow and drier blyr is progged, limiting shallow fog potential to the mtn valleys and locales who receive rainfall today. Upper ridge axis will continue to poke north into the region through Saturday. Expect another afternoon of typical scattered, diurnally fired, deep convective chances regionwide. Coincident with rising mid/upper level heights, afternoon maximums are progged to reach a category above persistence. && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/... As of 1200 PM Friday: Mid level heights will rise slightly during the Saturday night through Monday timeframe. This will lead to high temperatures climbing back into the middle 90s Sunday and Monday outside the mountains, with highs near 90 in the mountain valleys. Heat indices will also be climbing with some Piedmont locations getting into the lower 100s each day. Right now, we do not anticipate that a heat advisory will be needed in our area. An active convective pattern will continue during this period with mainly afternoon and evening showers and thunderstorms each day, with the highest chance in the mountains. && .LONG TERM /MONDAY NIGHT THROUGH THURSDAY/... As of 1210 PM Fri: A weakening cold front will push into the area on Tuesday. This will act to lower high temperatures just a couple degrees for the Tuesday through Thursday timeframe, but they will still be near normal to slightly above normal. The dissipating front will help to keep the chance of showers and thunderstorms above climo each day. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... At KCLT and elsewhere: Typical summertime, scattered, disorganized diurnally fired deep convection will continue to develop in the high terrain and expand into the Piedmont as the afternoon wears on. The potential cvrg is of high enough probability to maintain mention of mainly garden variety tstm threat all terminal locations this afternoon. After storms ash out this evening, unlike the past two nights, with a drier and weak westerly blyr flow, low cloud development probability is low and vsby restrictions should be limited to where it rains today and the usual mountain valleys. A pretty similar weather day is expected for Saturday. Outlook: Typical summertime weather is expected into early next week, with scattered to numerous thunderstorms mainly in the afternoon/evening and fog and/or low stratus possible each morning. && .GSP WATCHES/WARNINGS/ADVISORIES...
