Temperatures To Drop 20+ Degrees By This Afternoon. Watch Out For Icy Roads This Morning From Refreezing Rain/Melted Snow. Ned Ryerson Says So.

Posted on
The front is starting to push into western PA as temperatures will start to drop dramatically throughout the morning and into the afternoon. These temperatures will drop to below freezing, allowing for ice to form on untreated surfaces. Temperatures drop into the 10s this afternoon, making road treatments less effective by then. A chance of snow is possible on the back edge of the system, but accumulations should be light. Conditions will dry out into Tuesday as partly sunny skies are expected. Another risk of snow will move in on Wednesday. Afternoon highs today will only be in the 10s while lows overnight drop into the single digits and low 10s. Highs in the low to mid 20s are expected on Tuesday before 30s push in on Wednesday. Lows will hold steady in the low to mid 20s on Tuesday night before single digits push in on Wednesday night. The DC Region will see the chance of rain continue today before mostly sunny skies push in on Tuesday. Partly sunny skies are expected on Wednesday. Highs in the low to mid 40s today will drop into the 30s tomorrow before mid to upper 40s push in on Wednesday. Lows in the upper 10s/low 20s tonight will rise into the mid to upper 20s tomorrow night before Wednesday night brings mid to upper 20s in. Drive safely today and take care folks! Stay warm and Happy Groundhog Day!
