Frost Delayed as Warmth Lingers | Grand Rapids News

First frost? Not yet — but the chill is creeping in up north. Ironwood and Iron Mountain hit chilly 30s, while Cadillac had a whisper of frost. For real frost (around 35°F), we’re still waiting — northern Lower Michigan usually sees it by Sept 5, but not this year. The jet stream’s not dipping enough to bring widespread cold. Expect a warm pattern to stick around through at least early October, with the coldest day coming Friday, Sept 25 — even then, frost will be scattered and limited to the northernmost spots.
