Well it is going to get cold and there will be some accumulating snow in western PA. The picture is of snow totals through Tuesday night. Didn’t have much time to draw this, so I apologize if this verifies terribly. The precipitation will start as rain before changing over to snow later tonight. This chance of snow will continue into Tuesday, especially near the lakes. Conditions will clear out on Wednesday. Highs will reach into the 40s today before lows drop into the 20s and low 30s. Highs in the 30s will persist through Monday while lows dive into the 20s. For DC, a chance of flurries are possible late tonight and tomorrow morning before dry conditions stick until Wednesday. Highs in the mid to upper 50s to low 60s today will give way to 40s Tuesday and Wednesday. Overnight temperatures in the 40s tonight will give way to 30s tomorrow night. Anyways, have a fantastic day!
