Another risk of thunderstorms Wednesday; Colder and drier late-week

High temperatures today reached 86 degrees in Alpena, 89 degrees in Sault Ste. Marie, 90 in Grand Rapids and 91 in Traverse City. A very warm and sultry air mass has moved into Northern Michigan well ahead of a cold front that remains hundreds of miles to our west.

Plenty of moisture and built-up afternoon instability have led to scattered showers and thunderstorms that developed over parts of Northeast Michigan. These are mostly driven by daytime heating, so after sunset these showers will tend to weaken. We will likely have another round of showers and thunderstorms popping up Wednesday midday/afternoon.

Low temperatures overnight will be near 63 degrees with partly cloudy skies. Wednesday will start with a mix of sun and clouds, morning temperatures will be in the lower 70s. A light breeze out of the south will keep directing warmth and high humidity into our area. Afternoon highs will reach about 81 degrees. Scattered showers/thunderstorms are expected to develop in the afternoon, and a chance of spotty showers will linger into the evening.

After tomorrow, temperatures will be heading on a cooling trend and humidity levels will follow suit. Highs on Thursday will be in the middle to upper 70s. A cold front will move through on Thursday, then winds will shift out of the northwest and it’s going to get noticeably colder for the end of the week. Highs Friday will be near 70 degrees, and highs in the 60s are forecast over the weekend.

Wednesday will be another warm and muggy day with highs in the lower 80s. Scattered showers/thunderstorms are possible midday to evening. Widespread showers are likely Thursday, soaking at times, and highs will be around 76 degrees. Cloud cover will decrease on Friday, and highs will reach about 70 degrees with much lower humidity.
