Sunshine will be in abundance Monday as Canadian high pressure continues to build into the Great Lakes. This high pressure will feed in a dry, easterly wind which will bring lots of blue sky and comfortable temperatures - upper 60s to upper 70s across northern Michigan (coolest near Lake Huron). Quiet conditions extend into Monday night with mostly clear skies expected, meaning stargazing will be perfect.
Dry weather/mostly clear skies will linger into most of Tuesday before clouds begin to thicken up by the afternoon and evening. The increased cloud coverage is in response to low pressure approaching the region, and will eventually bring increasing rain chances throughout Tuesday night. Rain, and possibly a thunderstorm, will carry over into Wednesday as low pressure gradually exits.
Tranquil conditions return on Thursday, but it is Friday and into the weekend when an expansive area of heat/humidity will get drawn across the Western Great Lakes region rolling in off the Plains. Temperatures will jump from the mid-70's/mid-80's Thursday into the low-80's (north) to low-90's (south) on Friday and well into the 80's (north) to mid-90's (south) by Saturday. Dew point readings will climb into the 70's leading to very muggy and uncomfortable weather. Certainly time to crank the AC or the fan back on. There could also be a few thunderstorms skirting the northern edges of the building heat Friday into Saturday mainly affecting the U.P.
