Winter won't let its guard down across the Upper Mississippi Valley and Great Lakes. A fresh winter storm is leaving a swath of heavy snow this morning from Iowa to Michigan. Fortunately, the wintry weather will subside later today.

Low pressure swirling across Lake Michigan will slowly pull north into Canada later today. Moisture wrapping around the low is spreading light snow from Des Moines, Iowa, to Marquette, Mich.

Sioux Rapids, Iowa, has been the jackpot winner so far with 14 inches of snow. Totals are noticeably less far north and east with 4 to 8 inches across southeastern Minnesota into northern Michigan. However, travel is not recommended across western Wisconsin and northeast Iowa due to snow-covered roads and icy patches.

Winter Storm Warnings and Winter Weather Advisories continue from central Iowa to northern Michigan, including Des Moines, Iowa, Eau Claire, Wis., and Marquette, Mich.

The heaviest additional accumulation will fall across the shores of Lake Superior with 11 inches possible in places like Marquette, Mich., where cold air flowing across the warm lake water will enhance snowfall through Tuesday. Farther south, an additional 2 inches will coat western Wisconsin, southeastern Minnesota and central Iowa before wrapping up later this morning.

A much weaker disturbance moving in behind the departing low will spread much lighter snow across the same locations again Tuesday. New accumulation will be less than an inch as this low quickly motors along towards the south and east.

Snowfall has been generous so far this winter across the Upper Mississippi Valley but scarce in the Great Lakes. Des Moines, Iowa, is a foot above average with 42.3 inches accumulation. Eau Claire, Wis., has also seen a snowy winter with 53.8 inches accumulation compared to an average of 39.5 inches. The lack of lake-effect snow has put Marquette, Mich., behind average by two feet, with 139 inches accumulation.
