Parts of the Plains and the Midwest are in for an autumn snowstorm. After a jet stream ravaged the Pacific Northwest, damaging power lines and trees in Seattle, the stream will move into the Rockies and Plains, according to Weather.com.
Monday, the steam will remain over the West, generating light to moderate snow over the northern Rockies and Wasatch.
Heavier snowfall will then spread to the Colorado Rockies Monday night, and over a foot of snow could accumulate by Tuesday. The early snowstorm will then spread east to the Plains and Midwest.
By Tuesday morning, the snow will fall over the Plains of western and northern Nebraska, southern and western South Dakota, eastern Wyoming and to northeast Colorado. Several inches could accumulate by Tuesday morning.
By the afternoon, the snow will spread northeast into parts of eastern South Dakota, northwest Iowa, northern Wisconsin, Minnesota and western Michigan. Wet snow may mix with rain during the evening commute on Tuesday in Minneapolis/St. Paul, but snow accumulation will be minimal. Five inches or more is expected from western and northern Nebraska into northern Wisconsin and western Michigan.
The accumulation of snow will increase in western and northern Nebraska into Tuesday night, and accumulation could also increase from South Dakota eastward. On Wednesday, wet snow will continue from the Upper Mississippi Valley into the Great Lakes.
Although it may seem early for a snowstorm, the average date of the season's first snowfall in many Western and Midwest locations is Nov. 1 or 2, so it is not unexpected.
