Central and southern New Hampshire, including Manchester and Nashua, could get 5 inches (13 centimeters) of snow, with Boston picking up almost a foot, according to the National Weather Service.

This will bring about 2 inches to Washington and possibly 4 to Philadelphia, said David Roth, a meteorologist with the U.S. Weather Prediction Center in College Park, Md.

There could be flurries on Wednesday or Thursday as arctic air moves in, dropping temperatures by Friday for the weekend.

Light rain this afternoon will transition to snow overnight.

A blizzard warning is in effect for much of the South Shore and The Cape & Islands from 4 a.m. Monday until 7 p.m.

Strong winds will also cause blowing snow and wind chill values below zero. Those could lead to some minor accumulations, but less than an additional inch from Tuesday’s snow.

Tuesday night: Mostly cloudy, low around 1.

The rest of the week gets progressively colder as temperatures slide from highs in the 20s for the remainder of the workweek, to only the upper teens by Saturday.
