WASHINGTON — The D.C. area is getting the heavy snowfall it’s mostly dodged this winter — an expected 8–12 inches, according to Storm Team4 Meteorologist Doug Kammerer.
Portions to the north and west could see up to 16 inches when the system rolls in early Wednesday, while portions to the south will get off easier — up to 8 inches. A Winter Storm Warning has been issued for most of the D.C. area from 2 a.m. through 8 p.m. on Wednesday. Expect hazardous travel conditions.
Kammerer thinks the snowfall will be historic. “We haven’t seen a storm similar to this this late in the season for about 50 years,” he said, referencing a storm in March 1964.
For the rest of Tuesday, expect a wintry mix mainly around the District. Areas to the north and west will see more snow, while areas to the south and east will see more rain.
D.C.-area schools were already bracing for the wintry conditions. The University of Maryland, College Park, has already announced it will be closed Wednesday, and dozens of other schools are likely to follow suit going into Tuesday evening.

Comcast has offered to help residents in the D.C. area stay connected during the storm by opening more than 3,500 Xfinity WiFi hotspots at select outdoor and business locations. This free service is available to anyone — including non-Xfinity Internet customers — through Monday, Mar. 26.
Here is the forecast:
- Tuesday: Cold, wet and breezy. Rain will mix with sleet this afternoon. Minor accumulations are possible.
- Overnight: The snow begins. Lows will be in the high 20s to low 30s.
- Wednesday: The snow really kicks in during the early morning hours; 8–12 inches of total accumulation likely around D.C. Areas to the northwest could see even more.
- Thursday: Partly to mostly cloudy, breezy and cold. Winds will be between 15 and 25 mph, but the highs will be between 38 and 44 degrees.
Travel and transportation
Amtrak has canceled dozens of Northeast region trains running Wednesday. That includes several Acela trains to New York and Boston, as well as one train along the Capitol Limited line to Chicago and two trains each along the New York/Miami Silver Meteor and Silver Star lines.
MTA Commuter Bus Service will not operate Wednesday, except Route 201, which will operate on regular weekday service as long as possible through the severe weather conditions.
The Maryland Department of Transportation State Highway Administration had crews pre-treat highways and bridges in northern counties in advance early Tuesday, as nighttime temperatures will increase the chance of roads refreezing.
Maryland crews are clearing stormwater management systems of debris to enable positive drainage and preparing chain saws, chippers and generators, and road closed signs.
The weather service also advises that commuters expect slippery road conditions Tuesday going into Wednesday and reduced visibility at times.
