... High pressure will build from the Tennessee Valley toward the region through the end of the week. A cold front may approach from Pennsylvania this weekend.
NEAR TERM /THROUGH 6 AM WEDNESDAY MORNING/... Most locations have reached the 70s as temperatures continue to drop this evening. A ridge of high pressure will keep us dry and quiet the rest of the night with dewpoint temperatures lowering into the upper 50s to lower 60s.
SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... A large high pressure ridge will provide quiet and seasonably warm conditions Wednesday. A westerly flow Wednesday will keep dewpoints from rising. Heat indices will be close to actual temperatures during the day. Any chance of showers or thunderstorms would be mainly along the Maryland border.
Wednesday night will be quiet. Any showers or thunderstorms along the Maryland border early will dissipate with loss of daytime heating and sunset.
By Thursday, flow backs slightly to the southwest, so the humidity may rise slightly by then.
Subsidence should mostly inhibit convection Thursday too. The forecast will remain dry.
LONG TERM /FRIDAY THROUGH TUESDAY/... Mid-upper level ridge will be at its maximum amplitude over our CWA Thu and Fri with continued hot and dry conditions. Hottest temperatures are expected Fri and possibly into Sat too. Digging upper level closed low from James Bay into northern New England Sunday will help push a weak cold front through the area Sunday and bring a slight reprieve to the hot weather (highs around 90 as opposed to mid 90s) along with a chance of showers and thunderstorms mainly to northern areas Sat afternoon and Sunday. Saturday could turn out to be the hottest day just ahead of the frontal passage and also when humidity is expected to be highest. It could be close to heat advisory criteria in some areas Sat especially in the south. Ridge tries to build from the west toward the middle of next week with temperatures climbing back well into the 90s.
