Winter Storm Quinn has brought blizzard conditions to the northern Plains and also spread snowfall through the Midwest and Great Lakes to begin this week.
Quinn will bring heavy snow to the Northeast Wednesday as a coastal low-pressure system develops. For more details on the Northeast forecast for Quinn, see our coverage at the link below.

This winter storm is being fueled by a potent southward dip in the jet stream that dumped heavy snow over the Mountain West the last several days. That plunge of the jet stream is now marching eastward across the rest of the country.
Winds gusting 30 to 50 mph will continue to result in areas of blowing and drifting snow in the northern Plains through Tuesday.
The worst conditions are expected from central and southeast South Dakota into northeast Nebraska and far northwest Iowa where blizzard warnings remain posted.
Interstate 90 in central and eastern South Dakota and Interstate 29 in eastern South Dakota remained closed as of Tuesday morning.
