First Frost Advisory for Michigan tonight

A Frost Advisory has been issued for about the western half of the Upper Peninsula tonight and early Thursday morning.

This is the first Frost Advisory here in Michigan for this fall season.

Temperatures are going to fall into the upper-20s to lower-30s at the inland areas of the western U.P. Ontonagon, Houghton, Baraga, Marquette, Gogebic, Iron and Dickinson Counties are in the Frost Advisory.

Since we haven’t been this cold so far, the frost could kill cold sensitive plants.

Here is the forecast for low temperatures early Thursday morning.

Low Temperature forecast for Thursday, September 10, 2020

The shoreline areas along the Great Lakes will stay warm enough for no frost. The Great Lakes have a large warming effect during fall, keeping shoreline areas much warmer than just a few miles inland.

Lower Michigan doesn’t have to worry about frost Thursday morning. Friday morning could be a different story, especially for inland areas of northern Lower Michigan.
