Warmest weather of the season in sight Heading for the 50s, possibly 60 degrees next week WXMI and last updated 2021-03-03 00:39:35-05 WEST MICHIGAN â The weather pattern has turned milder over the past week with the snowpack disappearing quickly around West Michigan. High temperatures hit the upper 50s to lower 60s from around I-94 and southward to the Indiana Line this past Sunday. We did not, however, hit 50 degrees in Grand Rapids. That looks to change by early next week. A much milder type of a regime is going to be setting up for several days next week with the mercury likely pushing well into the 50s. We have a shot to get to 60 degrees!
