Introduction to the Winter Weather
A surge of cold air is set to arrive in the D.C. region on Thursday night, setting the stage for measurable snowfall in the area early Friday. This cold front is expected to bring temperatures down to just the upper 10s and lower 20s, which is low enough to allow any drizzle or rain to fall as snow. According to 7News First Alert meteorologists, a low-pressure system will arrive in the mid-Atlantic after it moves across North Carolina and southern Virginia, making it cold enough for snow to fall in the D.C. region.
Snowfall Expectations
The potential for snowfall in the D.C. region is significant, with a dusting of snow expected in D.C. and slightly higher snowfall expected in areas south and east of the District. Around 2 inches of snowfall is forecast from Culpeper, Virginia, to Waldorf, Maryland. It’s worth noting that the last measurable snowfall in D.C. in the month of December was back in 2017, with 2 inches at Reagan National Airport, according to 7News. This snowfall is expected to start between 4 a.m. and 7 a.m. on Friday, with steady activity between 7 a.m. and 1 p.m., and is expected to taper off in the afternoon.
Temperature and Road Conditions
The steep temperature drop means any snow that falls will stick around until temperatures warm back to the 40s on Saturday afternoon. Snow or no snow, it will be very cold on Friday, with wind chills pushing temperatures down into the 10s and 20s all day. Road conditions could be slick on Friday morning, according to the National Weather Service, and the District Snow Team will be salting streets on major D.C. roadways beginning Thursday night.
