WASHINGTON — A nor’easter is expected to sock the Northeast Monday and Tuesday, bringing with it snow and high winds.
According to the National Weather Service, colder than normal weather is expected across much of the nation. Michael Schichtel of the National Weather Service’s Weather Prediction Center says the storm could pack a wallop, with some parts of the region getting a foot or more of snow.
“It’s cold enough for, well certainly, some very significant snows — upwards of half a foot or more through the metropolitan Washington, D.C.-Baltimore area,” Schichtel said. “As you get up towards the northeast, for New York City and Boston, certainly the interior sections could get quite a wallop out of this.”
NBC Storm Team 4 Steve Prinzivalli said forecasters were still monitoring a developing late-winter storm poised to slam the area with heavy snow and a wintry mix Monday night.
School closures are likely Tuesday and possibly into Wednesday. Many roads will be impacted Tuesday and flight delays and cancellations are possible.
Forecasters say 5 to 10 inches are expected in Maryland’s Frederick and Montgomery counties, and in Virginia’s Loudoun County and the northern portions of Fairfax, Prince William and Fauquier counties.
Two to 5 inches of snow is expected in D.C., parts of Northern Virginia, and in Prince George’s and Charles counties in Maryland. A wintry mix is possible at times, which could cut down on the snow totals.
The lightest snow totals are expected in the southern suburbs, such as St. Mary’s and Calvert counties in Maryland and Virginia’s Northern Neck region, where totals range from a dusting to 2 inches, Prinzivalli said.
Prinzivalli said that two disturbances — one diving down from the Midwest and a second one carrying moisture from the Gulf of Mexico — are expected to merge near the mid-Atlantic coast Monday night, creating a powerful nor’easter.
The snow is expected to hold off for the Monday evening commute, but motorists should plan on staying off the roads overnight into Tuesday, according to Storm Team 4’s Amelia Draper.
The most snow is expected to fall overnight through at least 8 a.m. Tuesday. The bulk of the accumulation is expected west of Interstate 95.
Due to blowing and drifting snow, the snow is expected to be heavy and visibility is expected to be poor on Tuesday morning. Driving will be difficult in the blustery conditions, Prinzivalli said.
The snow and wintry mix is expected to diminish Tuesday afternoon — replaced by gusty winds and frigid wind chills, Prinzivalli said.
Temperatures in the D.C. region had already taken a dramatic plunge over the weekend, going from the spring-like 70 degree warmth to unseasonably cold 30s and 40s.
Temperatures on Sunday were expected to reach 40 — about 15 degrees below average.
One of the worst March storms in modern memory occurred in 1993, when a super storm dumped more than a foot of snow in parts of the region and winds gusted over 40 mph.
