Periods of snow will make travel difficult across West Michigan as colder, Canadian air combines with plenty of upper level energy to produce a strong low pressure system with locally heavy lake-enhanced snow overnight into Friday.  Look for road conditions to be snow-covered and very slippery as temperatures fall into the 20s, especially for the Friday morning commute.

The heaviest snow will fall along U.S. 131 from Grand Rapids and Kalamazoo westward into the lakeshore counties.  Storm total accumulations of 3 to 6 inches will be common in these areas with lesser amounts farther inland toward Lansing and Jackson.

Once low pressure moves east, a northwest wind will set up some locally heavy lake-effect snow bands across Southwest Lower Michigan where additional accumulations of 3 to 6 inches could occur during the daytime Friday into Friday night.  A few locations along the lakeshore south of Holland, and west of Kalamazoo could see storm total accumulations of 10 to 12 inches by Saturday morning. 

Northwest winds will gust to 30 mph and cause some blowing and drifting snow.  Driving conditions will deteriorate across West Michigan overnight leading to a challenging morning commute, and the possibility of some school closings and delays, on Friday.
