Northeast U.S. | Nor'easter

Snow on backside of major Nor'easter, warnings continue

Staff Writers

Wednesday, March 14, 2018, 9:15 - The third winter storm in two weeks roared into coastal New England on Tuesday, with two feet of snow causing school closures, flight cancellations and power outages. The nor'easter follows two storms that rumbled up the East Coast this month, killing at least nine people and knocking out power to about 2.4 million people and businesses at their peak.

This latest storm left a big mark on Boston with one foot of snow officially measured. Other areas such as East Killingly, CT measured 20.1 inches for fresh heavy snow and Willmington, MA got 29.5 inches. 

Significant winds were clocked in at:

  • East Falmouth: 81 mph
  • Hyannis Airport: 79 mph
  • Nantucket: 77 mph

Weather Highlights:

  • Very strong winds will likely lead to storm surge/coastal flooding Wednesday for Maine.
  • Heavy snow showers in place over much of New England on Wednesday near a trough of low pressure
  • Region clears on Thursday

Cold weather and snow showers are expected to persist over the Northeast through Thursday in the wake of the big nor'easter, according to the National Weather Service. Accumulating snow is likely from the central Appalachians to Maine, and some lake enhanced snow is also possible. 

Afternoon highs in the 30s and 40s are expected for much of the eastern U.S. on Wednesday, which is below normal by mid-March standards. See below for aa closer look at what you can expect.

  • With a blocking pattern remaining in place, the nor'easter is expected to directly affect Nova Scotia on Wednesday and then weaken. This will keep the snow and snow showers in place over much of New England on Wednesday near a trough of low pressure
  • Additional snow accumulations expected: 7-10 inches (locally up to 14) for parts of Vermont; 4 to 6 inches are expected for parts of Maine; 5-10 inches for parts of Upstate New York; 3-6 inches for parts of New Hampshire
  • A Winter Storm Warning is in effect for New England. A Winter Storm Warning for snow means severe winter weather conditions will make travel very hazardous or impossible. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency. The latest road conditions for Maine can be obtained by going to
  • Winds gusting as high as 40 mph will cause areas of blowing and drifting snow, and could help to bring down snow covered tree limbs. Avoid unnecessary travel.

Why so many storms this year?

Seeing a series of storms like this is definitely 'normal'. Typically in the month of March, we see our greatest temperature contrasts of the winter season and these storms can track east of the Rockies, intensify and pick up moisture when they reach the coast.

The U.S. East Coast provides an ideal breeding ground for nor’easters. During winter, the polar jet stream transports cold Arctic air southward across the Plains of Canada and the United States, then eastward toward the Atlantic Ocean where warm air from the Gulf of Mexico and the Atlantic tries to move northward. The warm waters of the Gulf Stream help keep the coastal waters relatively mild during the winter, which in turn helps warm the cold winter air over the water. This difference in temperature between the warm air over the water and cold Arctic air over the land is the fuel that feeds nor’easters.
