A Fourth March Nor’easter is Possible as Spring Arrives Next Week, Bringing More Snow and Wind to the Storm-Weary East

Yet another nor’easter, what would be the fourth this month, may plague parts of the storm-weary East next week as an active March pattern extends into the first week of spring.

While the key details of this forecast, such as who will see snow or rain, how much snow will fall, and how strong the offshore low becomes are not yet in focus this far out in time, the general setup is a familiar one.

The mid-week setup for the potential nor’easter.

Namely, a sharp southward plunge of the jet stream will carve into the East.

Responding to that, low pressure should form near or off the East Coast around the middle of next week. 

Moisture will then wrap into sufficiently cold air near the surface to wring out areas of snow from the Ohio Valley to the Appalachians and Northeast.

Here is what we know about this potential storm.

Forecast Timing

This system will bring snow to the Sierra, Great Basin and Rockies this weekend before heading into the Plains and Midwest Monday, then to the East by Tuesday. Here’s our latest forecast timeline.

Through Sunday

• Snow will continue in California’s Sierra through Saturday, and will spread into the Rockies and Four Corners through the weekend.
• Several feet of additional snow will pile up in the Sierra, where travel will be heavily impacted over Donner Pass on Interstate 80.
• Snow or a rain-snow mix will also begin to push into the northern Plains by Sunday.

Monday

• Light to moderate snow will target the northern Plains.

Tuesday

• Low pressure should begin developing near or off the East Coast.
• Snow should develop from parts of the Ohio Valley into the Appalachians and mid-Atlantic, particularly later Tuesday.
• Areas to the south should see mainly rain.

Tuesday’s Forecast

Areas in darkest teal have the best chance of snow. Areas in pink may see either rain or snow. Areas shown in green are expected to see mainly rain.

Wednesday

• Low pressure should remain swirling off the Northeast Seaboard.
• Snow, possibly heavy, may stretch from parts of New England to the Mid-Atlantic, Appalachians and Ohio Valley.
• Strong winds are possible particularly along the coast from New England to the Mid-Atlantic coast.
• This may lead to coastal flooding, beach erosion, and possibly power outages and tree damage, yet again, in some areas.

Wednesday’s Forecast

Areas in darkest teal have the best chance of snow. Areas in pink may see either rain or snow. Areas shown in green are expected to see mainly rain.

Thursday

• Snow may linger in parts of the East, particularly in New England.
• Some lingering snow in New England may be heavy.

Again, it is too soon to determine who may see heavy snow from this potential nor’easter.

In general, there is potential for more snow to fall farther south in the Mid-Atlantic states than the past couple of storms.
