WEATHER BLOG: A Drenching Rain
While the week got off to a dry start Monday, moisture is already starting to take over what’s left of this dry air that was provided by a ridge of high pressure.
We will continue to monitor light precipitation drifting north and east throughout the afternoon and we will still have to account for the possibility of some frozen precipitation along the Mason Dixon line and in western Maryland where winter weather advisories are still in effect through the afternoon.
The rain is expected to come down harder and steadier late Tuesday afternoon and evening, raising our potential for flooding concerns along the I-95 corridor including the cities of Washington, D.C. and Baltimore. We could see as much as 2-4″ of rainfall by Wednesday afternoon.
As the storm system begins to depart Wednesday evening, some colder air will be getting pulled down from the north and west which will cause our temperatures to fall sharply after sunset. Most will be falling through the 30s during the evening and even into the 20s by late Wednesday night.
As we cool down, we may taper to snow showers on the backside of this system.
Thanksgiving still looks fairly sunny, but also colder with a brisk wind and temps no higher than the 30s.
