Midwestern and Northeastern regions will be hit with a Canadian storm and an Arctic blast

Northeastern During Tuesday night and Thursday in the Midwest and East, Arctic air will trigger more lake-effect snow close to the Great Lakes and dangerous snow squalls.

Strong winds, snow showers, and lake-effect snow are expected across portions of the Midwest and Northeast from Tuesday night to Thursday night.

Despite temperatures in the low teens, AccuWeather meteorologists warn snow squalls, flash freezes, and frigid air may occur on some highways.

Midweek, the storm will travel south from northern Alberta to southern Ontario and Quebec. Storms that track far to the north rarely impact the United States and cause precipitation.

The upcoming storm will not only strengthen, but also grow in size, potentially bringing snow showers as far south as the Ohio, Tennessee, and southern Appalachians.

Minnesota, Michigan, New York, and New England will have the most steady snow near the Canada border.

Beginning Tuesday night and ending Wednesday morning, a locally heavy lake-effect event will develop along the southwest shorelines of the Great Lakes.

Southwest winds will be stronger Wednesday through Thursday.

This will cause heavy lake-effect snow to drift towards the southern shorelines throughout the Great Lakes from northern Wisconsin and Michigan to northern Ohio, northwest Pennsylvania, and western New York.

Due to the heaviest snowfall since Thanksgiving weekend, some roads near the Great Lakes may close due to low visibility and heavy snowfall.

Snow drifts and blowing are likely to be worse during this event due to plunged temperatures and dried snow.

Storm Max TM gusts of 65 mph are expected near the Great Lakes and over some ridges near the Midwest and Northeast on Thursday.

In contrast to recent lake-effect snow, future snowstorms will have more widespread impacts than the recent round. A snow shower or squall can extend hundreds of miles away from a lake.

Thunderstorms in the summer are winter’s cousins. Their distribution tends to be localized, heavy, and repeatable.

Besides a drop in visibility, snow squalls can cause highway traffic to halt and a high risk of multiple-vehicle pile-ups because of a rapid thin coat of snow to several inches.

Snow squalls could wet the roads, and then they freeze before they are dried off by gusty winds. This could compound the problem.

As vehicles compress the snow, it briefly melts before it has a chance to turn into ice due to snow squalls.

It affects northern Wisconsin, Illinois, Indiana, the Lower Peninsula of Michigan, Ohio, West Virginia, New York, and Pennsylvania. It also affects parts of Maryland, western and central New Jersey, and much of New England.

Milwaukee, Chicago, Detroit, Indianapolis, and Columbus, Ohio could experience rapid freeze-ups from an Arctic airstream.

It will be cold enough in the Southeast with a penetrating breeze to cause pipes in poorly insulated areas of homes and businesses to burst.

Arctic air will blow mostly toward the Midwest, but it will get cold enough in the Southeast for pipes to burst in poorly insulated homes and businesses.

Temperatures will drop into the 20s Thursday night in Atlanta, Charlotte, North Carolina, and Birmingham, Alabama. Early December temperatures are 10-15 degrees warmer than average.

Outdoor garden operations in the interior Southeast and mid-Atlantic coast that have not yet been prepared for winter should do so as soon as possible.
