Heat wave grips northern Michigan

Heat Index values near 100F in spots Tuesday. Those outdoors need to remain hydrated.

After several warm to hot days, the heat across Northern Michigan will peak today into Wednesday before breaking late this week.

The National Weather Service has issued an Excessive Heat Advisory for all of our counties along/south of highway M-32 in the Lower Peninsula starting at noon Tuesday through midnight which includes places like Traverse City, Cadillac, Manistee, Houghton Lake and Clare.

That was issued as a potentially dangerous combination of heat along with elevated humidity levels will combine Tuesday afternoon to make the heat index (what it feels like) rise well into the 90's and in a few spots close to 100F for a couple of hours. Especially here in Northern Michigan, we don't get those heat index values too often so people may be unaccustomed to its effects on the body.

The key thing to remember is to remain hydrated (water is best) along with sports drinks throughout the day. If you work outdoors, make sure to take a break to avoid the effects of heatstroke. Also make sure that pets that are outdoors have plenty of water. Another reminder is to check on the elderly or disabled, especially those that do not have access to air conditioning or fans to remain cool.

One place to escape the heat is the Salvation Army in Big Rapids which will be open from 11:00 a.m. until 5:00 p.m. today. They will have a cooling center along with water and games. It is located at 325 Linden Street in Big Rapids.

With these temperatures, the nights have also been warm providing little relief in the overnight hours. There is a small chance both today and tomorrow for a passing thunderstorm which would be a good thing providing a little relief.

The heat will break, but not until late week. A cold front will barrel across the region Friday bringing with it thunderstorms. Some storms Thursday into Friday could be severe with damaging winds and/or large hail. We will keep a watchful eye on that scenario and keep you updated. By the weekend, temperatures will fall back into the 70's with a lot less humidity.
