The gusty winds will eventually slow down tonight. Once they do, conditions will be ideal for radiational cooling under mostly clear skies. We'll all end up in the 30s overnight, with the Lehigh Valley in the lower half of the 30s and Philadelphia in the upper half.
Monday will start off with bright sunshine before clouds slowly increase throughout the course of the afternoon. It will still breezy, but not as breezy as Sunday. High temperatures won't be all that bad, especially if you look at the rest of the seven day forecast, as they top out in the mid 50s for most locations.
An arctic cold front will slide through the region on Tuesday, bringing with it clouds, colder temperatures, and the threat for a rain or snow shower. Now by snow shower I don't mean accumulating snow, but don't be surprised if you see a few flakes out there, especially in the morning on Tuesday.
The chilly weather will persist on Wednesday before a warmer area of high pressure arrives for the remainder of the week and through the weekend. Thursday through Sunday look very nice with high temperatures recovering to the low to mid 50s.
