Winter storm warning, up to 18 inches of snowfall for Michigan’s Upper Peninsula


A very early cold snap is heading towards the upper peninsula. The cold will trigger an episode of heavy snowfall.

The Marquette National Weather Service has issued a winter storm warning for the western third of the Upper Peninsula. The winter storm warning is for heavy snowfall between tonight and noon Tuesday. Southwest of the heaviest snow area is a winter weather advisory for lighter snow accumulations.

A winter storm watch is also in effect for the central part of the Upper Peninsula from Monday evening through Thursday. The influx of cold air, combined with atmospheric flow that will support lake effect snow, will move east across the UP Monday through Tuesday.

Eventually, from Monday to Wednesday, there will even be snow accumulation over some of the regions of the lower Michigan snowbelt.

Here are the locations of the Winter Storm Warning and Winter Storm Watch.

Winter storm warning in pink, winter storm watch in blue, from 9:00 a.m. on Sunday 16 October. The warnings are valid for the end of Sunday until Tuesday.

The Marquette National Weather Service says this about the winter storm warning area: “Heavy, wet snow begins tonight and continues through Monday evening, resulting in poor moving conditions. Total snowfall accumulation of 8 to 16 inches in the higher terrain a few miles inland from Lake Superior with locally higher totals approaching 2 feet possible across the Michigamme Highlands. Winds blowing up to 45 mph through Monday afternoon, then up to 50 mph Monday evening.

Total snowfall forecast until late Tuesday morning.

I agree with this prediction.

The heavy, wet nature of the snow on this early date will weigh the trees down with leaves. Power outages will be possible due to the weight of snow on the trees and strong gusts of wind.

If you plan to travel across the Upper Peninsula from tonight into Tuesday, be prepared for some extremely bizarre and dangerous winter travel for this early date in mid-October.

The cold air pattern will move into Lower Michigan Monday through Wednesday. Look for an update tonight on how much snow may fall in parts of Lower Michigan.
