Cooling Down Significantly By Mid Week.

It is Monday, but the weekend was fantastic weather-wise. A chance of an isolated shower is not out of the question for western PA today before most of western PA dries out on Tuesday but NW PA could continue to see a chance of wet weather. Wednesday will bring a better chance of showers back into the region. Highs will rise into the mid to upper 70s today before upper 60s to low 70s track in on Tuesday. Wednesday will drop highs into the mid 60s to low 70s. Lows will bottom out in the 50s tonight before low to mid 50s settle in on Tuesday night. 50s will hold into Wednesday night. The DC Region will see a threat of showers and storms later tonight before partly cloudy skies track in on Tuesday and Wednesday. Highs in the upper 80s to low 90s today will drop into the low to mid 80s on Tuesday before Wednesday brings mid 80s into the area. Lows will dip into the upper 60s to low 70s tonight before mid to upper 60s roll in on Tuesday night and Wednesday night. Hope you all have a great day!
