WEST MICHIGAN — It may be the last day of May tomorrow and we may be coming off a few days this past week with heat indices in the lower 90s, but a Frost Advisory has been posted for northernmost sections of the viewing area. Officially, the advisory includes Oceana, Newaygo, and Mecosta counties for between 2 A.M. and 8 A.M. Sunday when temperatures can drop as low as the middle 30s. The true focus for frost is likely to be in the northern sections of these counties ( or typically coldest areas within these counties ) and northward from there. Nonetheless, frost is possible and could kill sensitive vegetation if left uncovered.

Completely clear skies, very light winds, and an extremely dry atmosphere will set the stage for readings to drop about 15 degrees below normal in the overnight. Grand Rapids, Kalamazoo, and Battle Creek will likely see overnight lows near 40 degrees ( averages in the lower half of the 50s ). It is not impossible for a few outlined locations ( the typically coldest spots locally ) to experience some light frost around the I-96 corridor as well.

The record overnight low in Grand Rapids for May 31st is 36 degrees from back in 1966. The record in Kalamazoo is also 36 degrees from 1897. The record in Battle Creek is 35 degrees from 1897. The forecast, however, does NOT take us quite that low early tomorrow morning. Take note, immediate lakeshore communities will likely hold in the lower half of the 40s overnight tonight.
