    We have just a few high level clouds today with below normal temperatures topping out in the low to mid 70s. Upper level low pressure trough will graze PA, MD & the north zones of WV. Low level moisture does not look sufficient to enough squeeze out anything more than some drizzle or maybe some virga this afternoon in those northern zones & some of the mountain counties. Virga is rain that does not reach the ground. Otherwise, high pressure over the Great Lakes contributes to somewhat clear and calm weather today and tonight. Lows will again fall into the low 50s, upper 40s and conditions will be calm enough for fog to develop early Wednesday.

    Warm front will push through Wednesday night into Thursday. Ahead of the front we can expect increasing cloudiness & warmer temperatures as a result of a southwesterly air flow. Showers and thunderstorms are expected Wednesday night/Thursday AM. Plenty of available moisture along with that system could produce locally heavy  downpours given the right conditions. Lows will be in the upper 50s, low 60s.

    We'll see a gradual clearing Thursday from southwest to northeast. Low pressure system will exit to the northeast. The passing of this front will mark a more seasonal temperature trend. This will  put daytime highs in the low to mid 80s, then closer to 90 by next week. We'll keep slight chances for rain and thunder Friday and Saturday. Skies will clear out late Saturday. Rain returns late Sunday.

Map shows HPC depiction of predicted 5-day rainfall totals. We'll get our fair share.
