... A strong area of high pressure will build and settle over the region resulting in well-above normal temperatures and limited rainfall for the rest of this week and through into early next week, with near- record temperatures expected for Memorial Day weekend.
NEAR TERM /THROUGH TONIGHT/... As of 640 am: Some fog and/or low stratus is observed in thew valleys draining into TN this morning per derived satellite imagery products. This should burn off quickly after sunrise. Otherwise, drier air (in the form of 50s dewpoints) in the wake of a weak cold front will continue to trickle into the forecast area this morning. This will lead to very little in the way of diurnal destabilization, and with a short wave ridge approaching/progressing across the area today, no deep convection is expected through the short term. Max temps are expected to be very similar to yesterday, perhaps a degree or so cooler in some spots.
Inverted ridging will develop/strengthen along the Eastern Seaboard tonight, as a 1020+ mb surface high settles into the northern Mid-Atlantic and New England. S to SE flow above this area of shallow high pressure may result in expansion of low clouds across the forecast area toward daybreak Wed. Otherwise, min temps will be about 5 degrees above normal.
SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... As of 340 AM EDT Tuesday: Latest guidance continues to prog an upper ridge extending roughly from the Great Lakes region down through the Southeast on Wednesday morning, while a negatively tilted trough is expected to be situated back across the northern Plains. With a recently passed cold front south of the FA, sfc high pressure across the area will continue build in from the north and wedge in place across the FA into Thursday as the center of the high gradually shifts eastward offshore. As this happens, the parent sfc low back to the west will allow for the front to the south to lift as a warm front, and curl around the wedge before dissipating.
With the anticipated low level moisture streaming in off the Atlantic as well as available instability, showers and thunderstorms will be possible on both Wednesday and Thursday, but will isolated in nature given the sfc high/ridging aloft in place. Of the two days, the higher of the low end PoPs are expected to be Thursday afternoon, confined to mainly the mountains and northern foothills, as piece of s/w energy rounds the upper ridge and moves over the area. Aside from the isolated convection and passing clouds, temperatures are expected to remain above normal through the short term forecast period, with Thursday being the hottest of the two days, setting the stage for the near-record temperature stretch on tap for the extended forecast period.
LONG TERM /FRIDAY THROUGH MONDAY/... As of 400 AM EDT Tuesday: As alluded to in the short term forecast discussion, the well above high temperatures are going to be the main story for the end of the week and through into early next week, with the all-time max temperature records for Charlotte, Greenville, and Asheville, listed in the Climate section of the AFD below.
By Friday morning, the aforementioned wedge is gone, and amplified upper ridging dominates the weather pattern through into the weekend, though guidance does suggest this feature becoming more dampened, with nearly zonal flow aloft Sunday night. Into Monday, broad upper longwave troughing will pass well to the north as upper ridge remains in place, with another upper trough slowly churning into the western portions of the CONUS. These two features will allow for the ridge to re-amplify over the area into next week, as the west coast trough propagates eastward into the central part of the country, with it's trailing cold front slowly approaching from the west.
Friday through into early next week, a few showers or thunderstorms cannot be entirely ruled out each day, with weak passing waves of s/w energy. Otherwise, with a mix of some passing clouds from time to time and plenty of sunshine, temperatures will remain in the 90s Friday through Tuesday, nearing the upper 90s in the weekend, across the Upstate and NW Piedmont, remaining cooler across the mountains. With the hottest temperatures so far this year anticipated for this weekend, it'll be important for anyone outside to stay hydrated and take necessary precautions to avoid heat-related illnesses.
