The Blizzard Warning has been extended until 6 AM Friday, along with the Winter Weather Advisory.
Arctic winds crossing Lake Michigan will blow lake effect snow showers across Southwest Lower Michigan through tonight. The snow ill be heavy at times and combine with blowing snow to cause whiteout conditions, especially on open roads. The worst conditions will be near Lake Michigan, but the strong winds and heavy lake effect snow showers will reach inland to Grand Rapids, Hastings and Kalamazoo.
In the blizzard warning, you can expect west winds gusting to around 35 mph and lake effect snow to result in visibilities frequently at or below a quarter mile. From 2 to 4 inches of additional snow will fall tonight. Travel will be difficult and some roads may be closed due to drifting snow and frequent white-outs. Wind chills will be at or below zero, so if you have to be outside wear layers of clothing and cover as much of your skin as possible.
In the Winter Weather Advisory area, the snow showers will not be as heavy but could combine with strong winds to produce local white-out conditions at times over open areas. Wind chills will also be below zero and 1 to locally 3 inches of additional snow will fall tonight.
Blizzard Warning and Winter Weather Advisory until 6 AM Friday.
