Here's an updated forecast before I turn things over to the next shift on this Thursday:
Lake-effect bands will continue as a rain/snow mix through midday, with a gradual shift inland and transition to all snow by late afternoon and early evening.
An upper-level disturbance is going to swing through tonight and disrupt the pattern a bit, generating a fairly heavy single band of lake-enhanced snowfall this evening and overnight. The biggest question is where that band will set up?
As of early this morning, the heaviest accumulation looked to be down toward I-94... but over time this morning, each computer model has gradually shifted it northward toward Grand Rapids and, now as of 11 AM, the Muskegon area. If that band sits still for a few hours, a narrow zone of 6"+ accumulations are possible, with only 1-3" outside of it. If it swings through the area gradually, the snow will spread out more into a general 2-4" accumulation. There will still be some decent lake-effect possible outside of that main swath, but that disturbance will be the main player.
Here's our latest computer model forecast of regional snowfall through noon Friday:
That dark blue area is the 6"+ zone (near Muskegon, in case you can't see the map outline), and the lightest blue is 2-4" (along and west of US-131 down to Kalamazoo).
Kevin will be updating the forecast tonight at 6:00 and 10:00.
