10/11/21 - Powerful Plains storm may spark isolated tornadoes, severe storms across Michigan and Great Lakes

A tightly cranked up storm system in the Plains will move across the Great Lakes region Monday night and Tuesday. Weather experts think severe weather is possible.

NOAA’s severe weather experts say there is a five percent chance of a tornado within about the western half of Lower Michigan and the far eastern part of the U.P.

This chance of a tornado officially fits in the time period of 8 a.m. Monday to 8 a.m. Tuesday, October 11-12, 2021

For Michigan the time period most likely to have a tornado or other severe weather is Tuesday 2 a.m. to 8 a.m.

The tornado possibility area includes Grand Rapids, Kalamazoo, Battle Creek, Coldwater, Lansing, Midland, Mount Pleasant, Cadillac, Traverse City, Mackinaw City and Sault Ste. Marie.

The area with the chance of damaging severe wind gusts in thunderstorms and one inch hail or larger is the same area as the tornado risk.

The heat of the afternoon and early evening create the most unstable part of the day.

Looking at one of the best weather models, it looks like a line of severe storms could hit the southwest corner of Michigan around 2 a.m. Tuesday. The storm line would then weaken as it moves east.

It is almost mid-October. It is definitely worth watching and alerting you since severe weather could come as a surprise at this time of year.
