WEST MICHIGAN — Expect a sunny Saturday across West Michigan with chilly temperatures in the mid to upper 30s for daytime highs. Winds will be much lighter than the past couple of days out of the northeast at 5-10 mph. Another cold overnight is expected tonight under mostly clear skies with lows dropping into the lower 20s once again.

Sunday will begin with sunshine but clouds increase late morning and for the afternoon as a weather system approaches from the southwest. Before this area of low pressure spreads any precipitation into West Michigan we look for readings to climb into the lower 40s on Sunday. Moisture will arrive from the south into southern sections of the viewing area nearer the Indiana line by late afternoon likely in the form of rain as surface temperatures will likely be too warm to support snow initially. Any precipitation holds off in Grand Rapids until early evening. Precipitation will change to snow through the mid-late evening and early overnight. Wet snow will have its best chance to accumulate between 10 p.m. and 6 a.m. Monday.

We are not looking at impressive amounts of snow but in fact mainly grassy accumulations of a coating to perhaps as much as 2 inches ( right now it appears that focus would be along the I-94 corridor ) for portions of the viewing area. A few slushy/slick spots could come about on area roadways in the overnight so watch your driving early Monday morning.

Any snow should be exiting around sunrise and clearing skies will work into the region through the mid-morning period. A good amount of sunshine is anticipated helping to boost temps into the mid to upper 40s by late day.

A couple wet weather systems will pass through the region as we go through the remainder of the upcoming week. A chance for showers enters the picture Tuesday afternoon and evening mainly for areas around Grand Rapids and southward. Another disturbance brings scattered showers late Wednesday evening into the early hours of Thursday. Yet another system may increase rain prospects through the second half of Friday. Temperatures will be in the ballpark of 50 degrees throughout the upcoming week.
