Moderate to heavy snow will continue through Thursday morning for far northeastern New England. Moderate to heavy lake effect snow will continue for the Great Lakes. Moderate to heavy snow will be possible for North Dakota. Across the Cascades and Northwestern Rockies, heavy snow will be likely for the higher elevations and moderate to heavy snow for the valleys. Heavy rain will be likely along the coastal areas of the Pacific Northwest.

Far Northeastern New England: Moderate to heavy snow will continue through the morning hours on Thursday as the low pressure system rapidly lifts northeastward into Canada. An additional 4-6 inches will be possible mainly across Maine and Northern New Hampshire.

Great Lakes: Moderate to occasionally heavy lake effect snow will occur on Thursday across the favored downwind areas in the Great Lakes where generally 2-5 inches is expected.

North Dakota: A clipper system tracking across the area on Thursday will generate moderate to occasionally heavy snow of 3-5 inches. The combination of gusty winds and temperatures in the single digits to teens will lead to dangerous low wind chills well below zero.

Cascades into Northwestern Rocky Mountains: A new low pressure system frontal boundary will push onshore the Pacific Northwest early Thursday, allowing for heavy snowfall across the higher elevations of the Cascades and Northwestern Rockies. 8-14 inches will be common across elevations over 6000 ft, with lesser amounts of 4-8 inches expected elsewhere.

Coastal Pacific Northwest: Frontal boundary mentioned above will allow for the development of heavy showers across the region on Thursday, leading to rainfall accumulations greater than 2 inches and some flash flooding.
