Partly to mostly sunny skies held across Mid-Michigan Wednesday as a north to northeasterly wind prevailed. With that wind in off of Lake Huron, we had quite a range of temperatures. The southern parts of the area saw temperatures approach 90-degrees. North of the Bay, and along the Lake Huron shoreline, temperatures stayed in the 70s. Winds will be shifting to the south and southwest for the next couple of days, so it will be getting hotter and more humid for all of us for week's end.
Thursday will feature partly sunny skies, south to southwesterly winds up to about 15 mph, more humidity, and a chance of a few showers and thundershowers. High temperatures for the day should end up surrounding the 90-degree mark for the ABC12 viewing area as a whole. The Heat Index will push into the upper 90s during the afternoon. Friday will be even more uncomfortable. High temperatures will be cruising through the 90s, with Heat Index readings topping-out between 105 and 110.
Some scattered thundershowers will be possible for the weekend, but I don't see any day-longs rains. Saturday's high will top 90 for most of the area, but readings will top-out only in the middle 80s for Sunday. There will still be high humidity hanging in the air through the weekend. Right now, it looks like we will see significant relief from the heat and humidity early next week. With winds shifting in from the north, highs will retreat to near-normal levels, and humidity levels will fall significantly. - JR
