The D.C. region is facing wet and windy conditions Thursday, and temperatures are expected to plummet overnight into early Friday.
That could mean some areas seeing passing flurries Christmas Day.
A flash flood watch is in effect until 4 a.m. Friday.
Flooding will continue to be an issue Thursday night as rain continues. Storm Team4 Meteorologist Mike Stinneford said the atmosphere over the region is “unstable,” and the severe weather threat will continue until the cold front moves through the area after midnight.
Here’s what you need to know:
- Powerful gusts. With gusts potentially going over 50 mph at times overnight, Anne Arundel, Calvert and St. Mary’s counties in Maryland are under a wind advisory until 2 a.m. Friday.
- Possible tornado threat further south. Along with the stormy weather, Storm Team 4 meteorologist Chuck Bell said there is a tornado threat from Norfolk, Virginia, into the eastern half of North Carolina.
- Falling temperatures. Temperatures will be steady or falling throughout Christmas Day, going down well below freezing Friday night.
Bell said you may need to prepare your home as well before windy conditions really hit the area.
“This will be problematic for any holiday decorations on your home or lawn,” Bell said. “Secure loose items early today, or risk losing them to the wind.”

A powerful storm system and an arctic front are coming together, bringing rain throughout the evening with a risk of “strong to severe thunderstorms” until early Christmas morning, Stinneford said.
The strong front will start passing through the D.C. area, and as it goes through the region, temperatures will plummet through early Friday morning.
