Arctic air, lake-effect snow continues to grip West Michigan


GRAND RAPIDS, Mich. (WOOD) — The Winter Weather Advisory continues until 4 p.m. Friday for the lakeshore counties, the next set of counties to the east of the lakeshore counties (Lake, Newaygo, Kent, Barry, Kalamazoo) and for Calhoun County.  This is for (mainly light) snow, a little drifting snow, plus cold temperatures and wind chills.

 

advisory

Temperatures will be stuck only in the teens Friday and over the weekend, with wind chill factors remaining near zero, and Arctic air sticks around through Sunday.  Temperatures will start to moderate late Monday.

With the cold air continuing to cross Lake Michigan, lake-effect snow showers will continue, more on than off in the lakeshore counties.  This is a long-duration event, with occasional snow showers lingering into at least Saturday.  Additional snowfall of 2-3″ (locally 4″) in the lakeshore counties with less snow as you move inland, away from the lake.

These are temperatures across the Midwest at 8 pm Thurs. That is a cold map! Lake Michigan is giving Michigan about a 5-degree warm-up. Look at how cold it is across northern Minnesota and North Dakota.  The temperature dipped to -36 at Embarrass MN last night, where wind chills were -40 to -50.

With a west-northwest wind persisting into the weekend, it’s not going to warm up soon. We will see a brief warmup next Tuesday night, when temperatures could briefly approach 40. Beginning Monday, the overall pattern is not as cold.

Finally, check out this MODIS satellite picture from this (Thurs.) afternoon. You’re looking at clear skies in Wisconsin, where there is snow on the ground. Most inland lakes are frozen, except for deeper Green Lake and Lake Geneva. You can see a “tornado scar” west-northwest of Green Bay from a tornado that occurred in 2007. The tornado cut a path mainly through a forest, and you can see snow on the ground where the trees were knocked down.

The lake-effect clouds are forming over Lake Michigan, giving us a cloudy day in Lower Michigan. If Lake Michigan were not there, West Michigan would have been sunny yesterday and today (Thurs.) and several degrees colder.
