WEST MICHIGAN — Expect conditions to continue to slowly deteriorate as we go along here on Saturday. The transition from rain to sleet and freezing rain is slowly marching southward as of 10:15 A.M.
A Winter Storm Warning continues until 7 A.M. Sunday. Though roads are already becoming slick, the worst of the road conditions will materialize later this afternoon and especially this evening.
A bit of a lull is developing for the early afternoon period where just a light brand of precipitation will be seen. Activity will pick up again later in the day into this evening as low pressure gathers itself and moves closer from the south.
Expect an eventual changeover to snow by mid-evening tonight in Grand Rapids. This changeover to snow will happen from west to east.
Ice accumulations will range between 0.10-0.33" for most of us to possibly as much as 0.50" in some locations out in easternmost sections of the viewing area. Sleet and snow accumulations will be greatest to the north of Grand Rapids where 4-7" can come down. Locally in Grand Rapids a 2-4"+ accumulation seems the best bet by early Sunday morning. Amounts will be lighter from Kalamazoo to Battle Creek but a couple inches or so of sleet and snow will still be possible.
The bulk of the wintry weather will be exiting by 4 A.M. Sunday with improvement building in thereafter. Though chilly in the 20s for highs tomorrow, some sunshine is likely to materialize through the late morning and afternoon.
