&& .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
-- Changed Discussion --
A dry first half of the weekend is expected as surface high pressure passes south of the area during the day, then over the western Atlantic Saturday night. Near normal temperatures in the upper 70s to lower 80s once again, with Saturday night lows a bit milder - in the low to mid 60s. A weak cold front looks to cross the area Sunday, bringing the next chance for showers and a few thunderstorms. Rain chances will be around 30-40pct, though any showers/storms look to remain isolated to scattered given the system lacks deep moisture. Highs Sunday afternoon reach the low to mid 80s, with 70s in the mountains. Dry conditions return Sunday night.

&& .LONG TERM /MONDAY THROUGH THURSDAY/...
-- Changed Discussion --
High pressure will build briefly into the region on Monday. There is a slight chance of a shower or thunderstorm, mainly during the afternoon or early evening, as a front will not be too far to the east of the region. Highs middle 70s in the west and lower 80s in the east. Shower and thunderstorm chances will gradually increase Tuesday and into Wednesday as high pressure moves east and the front nearby becomes a warm front and connects to an approaching low pressure system from the southwest. This low is expected to move northeast into the mid-Atlantic later Tuesday into Tuesday night. An associated cold front trailing this low could bring a reinforcement of showers and thunderstorms Wednesday into Wednesday evening. Highs Tuesday middle to upper 70s. Highs Wednesday near 80 to lower 80s. By Thursday, the low pressure system and its associated cold front move east. This will allow for high pressure to develop and build in from the west. Dry conditions should ensue with high temperatures lower to middle 80s.
