We will cap off 2020 exactly how you would expect – with a mess on Christmas Eve that will result in scattered power outages in eastern PA and some accumulating snow in western PA. A warm front will bring one to two inches of rain Christmas Eve across much of the state. And with temperatures soaring to 55 – 60 degrees in the eastern half of Pennsylvania, flooding concerns will exist as snow on the ground will quickly melt. Only a few hours later, an Arctic front will move through, dropping temperatures 20-30 degrees in three hours, and changing rain to snow in western PA. Watch for icy roads late evening Thursday into early morning Friday, as a flash freeze will occur especially in central PA.
