An area of high pressure over New England will continue to promote pleasant conditions this evening and overnight with low temperatures in the low-to-mid 50s. It will then shift into the western Atlantic during the middle of the week, with south- southwesterly winds ushering noticeably warmer and slightly more humid air into the Commonwealth. As a result, Wednesday will turn out mostly sunny with high temperatures around 10 degrees above average. After a mainly clear and mild Wednesday night, clouds will increase on Thursday in advance of a weak cold front. Ahead of the front, it will remain unseasonably warm and humid with high temperatures in the upper 80s and dewpoints in the mid-to-upper 60s. In addition, an isolated shower or thunderstorm may erupt Thursday afternoon and evening. In the wake of the cold front, northerly winds of 10-20 mph will direct cooler and less humid air into northern MD and southeastern PA on Friday. As a result, Friday afternoon should turn out mostly sunny and cooler with highs in the low 80s with dewpoints falling into the low-to-mid 50s.
