WEST MICHIGAN — A very large, powerful, moisture-laden winter storm will continue to affect Michigan Saturday evening into Sunday early morning. Many areas have already tallied two to three inches of precipitation, with a little more on the way. The last several forecast model runs have continued to trend the track of this system further south and east. That means the best corridor for significant icing looks to be from Kalamazoo, through Lansing, and into Flint...where .25" to .50" of freezing rain and ice are possible (total). Rain, sleet, and freezing drizzle have dominated throughout Saturday in and around Grand Rapids, which has generally kept ice accumulation down. That said, a second swath of precipitation arrives Saturday evening and continues overnight. Our updated map is below with precipitation amounts and types.

Thus far, a lot of the area has been fortunate since the changeover to frozen precipitation started late in the morning, then tapered off through the afternoon. Sleet and snow are better since they don't accumulate on trees and power lines. As this system trends further south and east, it appears that much of the area may trend toward more sleet and snow than actual freezing rain. Below is the county break out of warnings (pink) and advisories (blue).
