Arctic Air Mass to Accompany Lake-effect Snow for the Great Lakes

An intrusion of Arctic air is going to surge across the Upper Midwest and into the Great Lakes region beginning late this week, creating significant lake-effect snow. Read on for the details of this cold and snowy forecast.

Disruptive Weather Will Continue with Arrival of Arctic Air

It has been a wild week of weather for the eastern half of the country. While the immediate East Coast deals with an emerging bomb cyclone and atmospheric river delivering heavy rain, it will be wintry precipitation causing disruptions for the Great Lakes and beyond.

The same weather maker that is bringing rain to the zone from the Appalachians and over into the coastline will also feature a cold back end that will support the development of several inches of lake-effect snow. It has been less than two weeks since the Great Lakes were buried under feet of snow over the Thanksgiving holiday.

It is shaping up to be a disruptive day of weather on Wednesday for much of the East Coast thanks to the plume of moisture that will come along with high winds and fog as part of the budding bomb cyclone. The feature is forecast to gain intensity as the day progresses, complicating the Wednesday evening commute for millions in its path. The storm will pick up enough intensity to bring a mass of Arctic air from Canada toward the southeast, sending the temperatures tumbling across the Midwest and the Northeast.
