Extreme wind chills
A Winter Weather Advisory is in effect for Antrim, Kalkaska, Grand Traverse, Leelanau, Benzie, Wexford, Manistee, Mason, and Oceana counties. The advisory ends at various times over the next 12 hours, but the entire region has icy roads and new snow. Lake effect snow will continue, and anyone in northern Michigan could see some snow tonight and Thursday but it's the advisory region that will see more. And for some counties, the advisory will be extended into Thursday night and Friday.
There is a Wind Chill Advisory for Chippewa, Mackinac, Emmet, Cheboygan, Presque Isle, Alpena, Montmorency, Otsego, Crawford, Roscommon, Osceola, Isabella, Clare, and Mecosta counties Thursday through Friday. Dangerously low wind chills are expected at times the next couple of days and nights. Some of the wind chills could drop to as low as 40 below zero. Frostbite can occur in as little as 10 minutes to exposed skin in this kind of weather. The wind chill is the effect of the combined cold from the temperature and the wind.
Low thermometer readings tonight will fall into the 16 below to 12 above range. More snow showers are expected in northern Michigan tonight. And wind gusts from the north could reach up to 25 mph.
Thursday will be cold everywhere but the snow will be concentrated on the Lake Michigan side of the map. Near the lake, another inch or 2 will be common and some people could see another 3 or 4 inches of lake effect snow on the west side of the Lower Peninsula. If you live east of I-75 and in the Upper Peninsula, you could see some sun through the clouds. Wind gusts will be between 10-20 mph. Thermometer readings will be in the high of 6 below to 14 above.
Thursday night the low temperatures will be as cold as 25 below zero in the Upper Peninsula. The range of lows will be 25 below to around 0 but that's not the entire story. The wind will blow up to 15 mph, not a high wind, but that will drive the wind chills down to 30 or even 40 below zero Thursday night and early Friday. Plus, more snow showers.
During the day Friday, more snow showers will happen but it will mostly be lake effect on the Lake Michigan side of the Lower Peninsula. Some of us will get another 3 to 5 inches of snow in those lake-effect zones. And it'll be cold everywhere. Highs 8 below to 12 above. Wind will gust to 25 mph and will generate another day of extremely low wind chill temperatures.
Saturday will bring more scattered snow with a little sunshine. Temperature highs will range between 4 below to 15 above.
There will be some scattered snow showers on Sunday. We could see a jump in temperatures with highs in the 20s!
