Rising humidity will feed some thunderstorms this weekend

Thunderstorms will be possible Saturday, but more likely Sunday.

The weather looks to get more active as we head into the weekend with a few chances for thunderstorms.

With high pressure moving well away from the area Friday, winds have turned southerly and will remain that way into the upcoming weekend. This will help draw northward abundant moisture leading to a marked increase in the humidity. Friday for the most part still looks pretty decent with a nice amount of sunshine and comfortable temperatures with 70's almost areawide. The range Friday will be from 69F at Manistee/Leland to 82F at Bellaire/Mt. Pleasant. As we saw both Wednesday and Thursday, just enough moisture is available that married with some daytime heating, we could see a shower or storm (very limited coverage) pop along the M-37/US-131 corridors south of Kalkaska/Traverse City.

Saturday will start off quiet with temperatures quickly climbing into the 80's by afternoon. By the afternoon, scattered showers/thunderstorms will develop due to afternoon heating and along lake breezes off of Lake Michigan. Most of this will be confined to the Lower Peninsula but just about anywhere could see a storm Saturday afternoon. These will die off quickly Saturday evening.

Sunday and even more so Monday will be the "most active" weather days. With ample moisture in place and an unstable weather pattern in place, the approach of a strong cold front along with some stronger winds aloft will lead to multiple thunderstorm chances, some of which could become strong or potentially severe. I expect thunderstorms both days to be widespread across Northern Michigan. It turns sharply cooler again next week. In fact, by Wednesday into Thursday, daytime highs will remain in the 60's!
