Northern Michigan continues to bake under excessive heat and humidity
The hot temperatures will peak across Northern Michigan today before a major pattern change gets underway late this week with significantly cooler and drier air dropping in by the weekend.
It was a scorcher Tuesday with Indian River in Cheboygan County officially topping the list coming in at 97F in the afternoon hours. Boyne Falls and Cadillac were not far behind at 96F with many low/mid-90's noted across Northern Michigan. The heat index topped 100F for a few hours in spots.
More of the same Wednesday although it could be a degree or two hotter. Northern Michigan is situated underneath a dome of hot high pressure that covers much of the Central/Eastern United States from the East Coast to the Great Lakes into the Northern and Central Plains. A west-southwest wind will continue to pump in the heat/humidity.
We are forecasted temperatures to spike back into the low/mid-90's with an outside shot of a few upper-90's in our hottest locations Wednesday. When you marry that with dewpoints in the 70's, it will feel more like 98-103F which again is a dangerous level of heat, especially here in Northern Michigan where we are not as accustomed to it. Those working or planning on being outdoors need to make sure to have water on hand, and to avoid prolonged exposure to the heat and sun to avoid heatstroke. Pets that are outdoors should have plenty of water available and if you can, check in on the elderly and disabled to make sure they are doing alright.
There is an outside risk for a thunderstorm Wednesday, with the most likely spot being the Eastern U.P. if they do fire off.
A better chance for thunderstorms develops Thursday into Friday as a powerful cold front sweeps in. There are increasing signals that some of those storms (especially Friday) could be severe with large hail, damaging winds, and an outside tornado risk. We will keep a watchful eye on that. By the weekend, temperatures will drop into the 70's with cooler and more crisp nights.
