Last week brought the biggest snow so far this winter with many Midcoast locations picking up between a foot and a foot and a half as a nor'easter churned through the region. Here we are just a few days later and it looks like that storm will be topped as another (more potent) nor'easter moves in with totals of up to 2 feet for parts of the Midcoast possible. A Winter Storm Warning is now in effect for all of the Midcoast for Tuesday and Wednesday. Travel will be hazardous during this period especially for Tuesday with high snowfall rates and white out conditions.

An area of low pressure strengthening off the coast of the Carolinas Monday will move up the east coast through the late day and overnight and then move northeast through the southern Gulf of Maine Tuesday as it continues to intensify. The storm will take a turn north on Wednesday just to the east of Maine passing over Nova Scotia then into the Canadian Maritimes. The center of the storm will backtrack west slightly toward northeast Maine Thursday morning before eventually exiting the region late Thursday. With the storm lingering across the region for such a long period, impacts from snow accumulation will be felt across the Midcoast for a larger period compared to last week's nor'easter. Temperatures will be slightly colder with this storm compared to last week's nor'easter which will make for a lighter and fluffier snow that should stick less to trees and power lines. This will reduce the threat of power outages with winds not expected to reach damaging speeds.

A Storm Warning is in effect for out mariners with northeast wind gusts of up to 55kts possible Tuesday with seas building up to 6 feet for Penobscot Bay and 18 feet offshore. Winds will turn out of the southwest on Wednesday and be weaker with gusts only up to 30kts.


Here is a breakdown of what to expect through the duration of this storm:

Snow rates will continue to increase with moderate to heavy snow through the afternoon and evening creating possible white out (or blizzard) conditions with northeast winds sustained between 20 and 30mph gusting up to 40mph. Snow accumulations of 5 to 10 inches likely during this period.

Tuesday night

Moderate snow will continue through the night with periods of lighter snow possible with an additional 4 to 8 inches likely. Winds will turn out of the north and eventually northwest through the night and decrease in speed, sustained between 10 and 20mph with gusts to 25mph.

Periods of light snow will continue through Wednesday morning with another 2 to 4 inches possible as the storm stalls to the east. Winds will be lighter out of the west between 5 to 15mph.
