Discussion

The main weather event this week will be the passage of a strong cold front late Thursday night that will usher in a cold air mass for Christmas Day (Friday). This strong front will be preceded by heavy rain from later Thursday into Thursday night and it’ll turn quite mild on Christmas Eve with late day temperatures flirting with the 60 degree mark in the DC-to-Philly-to-NYC corridor. Winds will become an important factor as well later on Thursday and Thursday night with gusts past 40 mph possible and there can be a thunderstorm mixed in. On the backside of the front, temperatures will drop quickly early Friday, any standing water will freeze, and there can be a brief period of snow and/or sleet after the heavy rain event. The much colder air that arrives on Friday will stick around into the upcoming weekend and temperatures on Saturday will struggle to pass the 30 degree mark for highs.
