Snow to arrive late Sunday in DC, could impact Monday morning commute

Snow to arrive late Sunday in DC, could impact Monday morning commute

"Snow changing to a wintry mix across the interior Tuesday PM, rain along the coast early Wednesday AM", the National Weather Service said on Facebook Sunday afternoon.

A winter storm watch begins Tuesday afternoon for the Bay State, excluding Southeastern Massachusetts. "Again, the snow gets here late tonight with 1-2" on the ground by Tuesday morning.

Forecasters continue to closely watch a developing storm system that could dump up to a foot of snow on areas of southeastern Minnesota Monday night and Tuesday.

IMPACTS: Travel will again be hard and even hazardous starting overnight tonight and likely through Tuesday. Make sure you brush off your vehicle completely, and be very careful on those slippery roads! For the evening, we will likely see a transition back to snow as the system departs the region. Flakes should start falling around 3 Boston, the weather service said in forecasts early Monday.

Below, six maps from local meteorologists predicting how much snow will fall in MA. The US has seen some bitterly cold temperatures this year, as parts of the country are still thawing out from lows of -50C.

Precipitation should ease up starting in the early hours of Wednesday morning, although it could linger into the Wednesday commute, especially north and west of Boston. There's a possibility of around an inch of snow and sleet accumulation possible.

In Washington, the National Weather Service told people to anticipate steady snowfall from Sunday afternoon in the Olympic Peninsula, spreading into the Puget Sound area by evening. There could be a quick hit of non-accumulating snow on the backside of that storm Saturday morning.

How much is possible in an extreme case? According to, there is now a 47 percent chance of 3 to 6 inches of accumulation in the area, a 40 percent chance of between 1 and 3 inches and a 3 percent chance of 6 to 10 inches of snowfall.

And what if this storm's a dud?
