Increasing cloud cover and spotty rain showers are already creeping into southernmost parts of our forecast area today as deeper moisture lifts north. Temperatures are expected to reach the mid & upper 70s this afternoon despite the increasing cloud cover. Radar depicts spotty light showers across much of our area but odds are that a good deal of that is not actually reaching the ground. More widespread rain showers are expected to break out tonight. Generally cloudy skies and occasional showers are expected during the day Wednesday. A few showers & even a rumble of thunder are possible again on Thursday. Model guidance shows general agreement on much of the heaviest rainfall occurring in our eastern slopes along the Potomac Highlands and into central Pennsylvania into the end of the work week. 

Daytime temps will range in the mid 60s to near 70. Nighttime temps will stay on the mild side with persistent cloud cover providing a fair amount of insulation. So lows will stay in the low to mid 50s. Overall, temps will be trending a few degrees cooler each day. Then a cold front and associated trough will progress eastward outta the Great Lakes Thursday night/Friday. We'll likely see some measurable precip from that system as well. Much of the forecast area will pick up around 1.5 inches. While points east will see rainfall amounts closer to 2 inches before things dry out sometime Friday.

Your typical Fall weather pattern will unfold this weekend. Things will be a bit breezy with the passing of that cold front. Friday & Saturday, daytime highs will only reach the low 60s. While overnight lows fall into the low to mid 40s. High pressure behind the front will bring clearing skies, lots of daytime sunshine & a few cool, crisp nights into the weekend...Have a great day & thanks for reading!
