NEW YORK — A grab bag of weather conditions — including snow and sleet — will descend on communities from the mid-Atlantic to the Northeast, but with many people off for Presidents Day, today might be just another day to hunker down.

After much of the Northeast experienced record cold on Valentine’s Day, the National Weather Service said today would be snowy in many areas before sleet or freezing rain started and rain finally arrived.

Washington Mayor Muriel Bowser said she deployed the D.C. snow team Sunday ahead of the storm, which is expected to deliver a sloppy mix of snow, sleet and rain. One to 3 inches is forecast for today.

Outside the nation’s capital, the Virginia Department of Transportation staged nearly 2,500 trucks to treat and clear roads.

Philadelphia also could see 1 to 3 inches of snow, and New York City could get up to 4 inches before the transition to wet weather begins.

Meteorologist Bruce Sullivan said there could be significant snowfall — 4 to 8 inches — in eastern Ohio, western Pennsylvania and western New York. Some mountainous areas, including in North Carolina, could get even more snow.

The weather could have less of an impact because schools and many workplaces are closed for the federal holiday and traffic should be lighter than usual.

By Tuesday, when temperatures get higher, the rain and some runoff could cause flooding in some areas, Sullivan said.

Sunday’s teeth-chattering temperatures were some of the coldest on record from New York and Boston to Providence, R.I., and Hartford, Conn. Temperatures Sunday morning dipped as low as minus 40 on Mount Washington in New Hampshire.

The National Weather Service said the temperature in New York City’s Central Park fell to minus 1, a record for the date. The last time it was below zero in Central Park was in January 1994.

Boston reached minus 9, breaking a 1934 record by 6 degrees. It reached minus 16 in Worcester, Mass., breaking the 1979 record of 11 below zero. Providence hit minus 9 and Hartford reached minus 12, also breaking records from 1979.

In Montpelier, Vt., the overnight temperature hit minus 19, tying a record set in 2003. And South Lincoln, Vt., recorded 27 below zero.
