Discussion
A powerful cold front will come barreling towards the east coast from tomorrow night into early Friday and it’ll bring some wild weather with it to the Mid-Atlantic region for the night of Christmas Eve. Ahead of the front, there will be heavy rain, possible thunderstorms, and potentially damaging wind gusts which, unfortunately, raises the prospects of power outages. It’ll become much milder as well on Thursday with temperatures likely flirting with the 60 degree mark for late day highs. The combination of heavy rainfall and already wet grounds will likely lead to localized flooding in areas of poor drainage. On the back side of the front, temperatures will drop rapidly in the wee hours of the morning on Friday and hold in the low-to-mid 30's during Christmas Day. The cold air mass will stick around as we begin the upcoming weekend with temperatures on Saturday struggling to pass the 30 degree mark.
