A Frost Advisory was in effect for a large portion of Michigan early Sunday. It includeed Oceana, Newaygo, Mecosta and Isabella counties to the north, covering all of N. Lower Michigan and Upper Michigan.
Temperatures in city areas (Grand Rapids, Kalamazoo, Battle Creek, Lansing) dipped into the low 40s. We didn’t get frost in theses urban areas. Outlying areas will reach the mid-upper 30s, with traditional low spots (esp. with drier, sandy soil) reaching the low 30s. No significant frost/freeze damage is expected in fruit growing areas.
