Winter Storm Puts 40 Million People on Alert Across Midwest and Northeast

A formidable winter storm is poised to affect over 40 million individuals by delivering a mixture of snow, strong winds, and rainfall from the Dakotas through the Great Lakes region, stretching into northern New England in the coming days.

Currently, blizzard warnings extend from North Dakota's cities like Grand Forks and Fargo down to areas in Minnesota and Iowa such as Rochester and Mason City. Expect snowfall from 3 to 8 inches, accompanied by gusts reaching 45 mph, leading to hazardous whiteout conditions until Monday morning.

Michigan’s Upper Peninsula is also under blizzard warnings, with anticipations of 9 inches to 2 feet of snow and gusts peaking at 60 mph.

Winter Storm warnings span from eastern Minnesota to northern Michigan, including key cities like Minneapolis, Green Bay, and Sault Ste. Marie, expected to face heavy snow and gusty winds from Sunday through Monday.

Impact on the Northeast

The Northeast is bracing for winter weather advisories from Scranton, Pennsylvania, up to Burlington, Vermont, and in Portland, Maine, signaling potential freezing rain from Sunday through Monday.

In areas such as Buffalo and Jamestown, New York, a Flood Watch has been issued, with forecasts of up to 1.5 inches of rain expected from Sunday afternoon to Monday afternoon.

High wind alerts have been announced for Detroit and Cleveland as gusts could reach up to 60 mph starting Sunday night and continuing until early Tuesday.

Midwest Effects and Storm Progression

Snow had already made its entrance in Sioux Falls and Fargo early on Sunday, with the storm expected to sweep into the Midwest by the afternoon.

By midday Sunday, heavy snowfall is forecast for Minneapolis and Mason City, Iowa. Meanwhile, Green Bay and Marquette are predicted to experience a wintry mix, while southern Michigan, including Grand Rapids and Detroit, will see heavy rain.

As Sunday progresses, both Minneapolis and Marquette should brace for intense snowfall and strong winds come evening, leading to reduced visibility. By evening, Buffalo, New York, could also experience heavy rain and high winds.

A portion of the I-95 corridor from Philadelphia to Boston may undergo a temporary wintry mix or freezing rain by around 5 p.m. Sunday, turning to rain as milder air sweeps in.

Continuing Weather Challenges

Snowfall accompanied by gusty winds is predicted to persist in Michigan until roughly 7 a.m. ET on Monday, after which rain is expected with warmer air moving in from the north across the Northeast.

For the Northeast, wintry precipitation is likely to be concentrated over the elevated regions of northern New England and vast parts of Maine, with freezing rain particularly expected at higher altitudes.

Following this storm, as it moves out by Monday night, the region should expect some lake-effect snow. This ordinary lake-effect snow is anticipated along the eastern Great Lakes and into the interior Northeast and could linger into Tuesday and potentially Wednesday.

Anticipated Snowfall and Ice Accumulation

The heaviest snow accumulation is forecast for the Midwest. For example, cities like Minneapolis and Green Bay might experience between 5 to 8 inches of snow, paired with a light layer of ice.

Marquette and a significant portion of Michigan’s Upper Peninsula could accumulate 1 to 2 feet of snow. Wind gusts reaching up to 60 mph may generate blowing snow even after the snowfall ends.

In the interior Northeast, stretching towards the Great Lakes and northern New England, lighter snow and a mix of wintry conditions are expected. Some parts of northern New England might gather up to a quarter-inch of ice by Monday.
