Discussion
The month of December has gotten off to a cold start across much of the nation and it’ll stay colder-than-normal in the DC-to-Philly-to-NYC corridor right through the upcoming weekend. Strong and strengthening low pressure will pass by to our north on Thursday and its trailing cold front will push through during the morning hours. This low pressure system and its associated cold front will have many weather impacts on the region from later tomorrow into the day on Friday.
Ahead of the system, winds will increase from a southwesterly direction later tomorrow and tomorrow night and then can gust to 50 mph or so from a northwesterly direction later Thursday and Thursday night on the backside of the front. Also, there is a good chance of snow and/or rain showers on Wednesday night and snow showers are possible on Thursday morning - perhaps even a heavier snow squall - as the strong front comes through the area with small accumulations on the table. Finally, the passage of the cold front will flood the Mid-Atlantic region with another Arctic air mass that will keep temperatures around here well below-normal on Thursday night and Friday and we’ll experience the lowest wind chills so far this season.
