Area Forecast Discussion National Weather Service Greenville-Spartanburg SC 133 AM EDT Wed Jul 3 2024
SYNOPSIS
As dry and cooler high pressure moves off the East Coast tonight and Wednesday, the heat wave will again become established for the second half of the week. Hot and humid conditions are expected over the weekend with Scattered afternoon showers and thunderstorms from Thursday through Sunday, especially over the mountains.
NEAR TERM /THROUGH TODAY/
As of 124 AM EDT Wednesday: Another quiet night, with only some thin cirrus streaming down from the north and a few patches of high-based stratocu. No changes necessary.
Otherwise, dry sfc high will move off the coast through daybreak, allowing low- level flow to reorient to SE. This may allow some low clouds to possibly develop mainly west of I-26 toward dawn. No fog is expected though. Near-normal temperatures and more seasonable humidity look to return Wednesday; vertical profiles are still subsident but more cumulus can be expected, and a few showers can't be ruled out over the southwest NC ridges. This warrants a small area of 20%-ish PoPs there.
SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/
As of 115 PM EDT Tuesday: The mid to upper level ridging across the southeastern states will weaken over the short range period. This will unfortunately re-orient the surface high pressure pattern, which will shift the pleasant northeasterly flow of today around to the southwest by Independence Day Thursday. This change in flow will bring the higher heat and humidity back to the area. Temperatures will be warming each day with readings in the Piedmont reaching the mid 90s Thursday and mid to upper 90s Friday. With dewpoints climbing back into the lower 70s in the Piedmont, heat index readings will approach 105 on Friday afternoon and thus a Heat Advisory may be needed particularly for the lower Piedmont and Charlotte areas.
Heat and humidity will return to the mountains also. However, this should lead to early development of convection each day keeping temperatures in check.
LONG TERM /SATURDAY THROUGH TUESDAY/
As of 130 PM EDT Tuesday: A system in the Ohio Valley will push a weak cold front toward the area and bring a more active convective pattern with it on Saturday. Storms should develop in the mountains and push into the Piedmont in the afternoon. However, conditions will be hot and humid prior to any storm develop with heat index values again around 105 degrees in the lower Piedmont and Charlotte areas.
With more moisture in the area due to the front lingering across the area, expect temperatures to be slightly less hot and there to be an active convective pattern Sunday into early next week.
AVIATION /06Z WEDNESDAY THROUGH SUNDAY/
At KCLT and elsewhere: VFR at all terminals thru the period. Calm or light/variable wind through mid-morning, with only a few high clouds expected. Once we mix a bit, the wind is expected to come up from the SE to S based on the location of the sfc high moving off the Mid-Atlantic Coast. Moisture will be a bit more available today, so a few stratocu should be expected. As we lose daytime heating, the clouds should dissipate and wind should go light S or perhaps variable/calm once again.
Outlook: A return of more typical mid-summer humidity and diurnal convection returns Thursday into the weekend leading to possible restrictions each afternoon/early evening. Fog and/or low stratus may develop each morning, especially for areas that received rain the previous day.
