Lake-Effect Snow WARNING!January 31st, 2013 at 4:29 am by Bill Steffen under Bill's Blog, Weather
7:10 PM – One snow band sits right along I-96 now from Muskegon to Detroit. Roads are snow-covered and very slippery at times. Major accident on I-94 near Mattawan. Multiple semis involved, road closed. 3″ of new snow at the G.R. airport, nearly 6″ at Paw Paw and Schoolcraft. 17″ of new snow at Marquette, +7″ at Traverse City. Models give us snow more on than off thru Friday with periods of snow continuing through Tues. of next week. Latest European keeps us below freezing until at least Weds. and possibly beyond that. There’s a Lake-Effect Snow Warning for Ottawa, Allegan, Van Buren and Kalamazoo Counties and a Lake-Effect Snow Advisory for Mason, Lake, Oceana, Muskegon, Newaygo, Kent, Barry, Berrien and Cass Counties. This is going to be a long-duration event with not only significant snow, but also drifting and some blowing snow. We’ll also have cold temperatures (in the teens much of the time), strong winds (15-25 mph steady, with gusts to 35 mph, esp. at Lake Michigan) and low wind chills near zero.

The overnight European model gives G.R. 0.39″ precipitation and at a conservative 20-1 water to snow ratio, that would be 8″ by early next week. For W. Allegan Co. it has 0.72″ precipitation which would be nearly 15″. The NAM caribou has even more snow…thru Sunday AM it’s up to 13.3″ for Grand Rapids and up to 20″ in Allegan Co. The GFS Caribou has 6″ for G. R. by Sunday AM and 11″ for Muskegon with over a foot in Allegan Co. BTW, the totals for G.R. are at the airport – there would be more snow than that in western and especially southwestern Kent Co. This is a long duration snow period and even light snow is going to add up. The GFS doesn’t take us past 30 until the middle of next week. We have the lake-effect thru Friday, then a couple of clipper systems. Also, whoever gets a foot of snow will see at least 2 foot drifts. I did see a couple of G.R./Kent Co. plows out this morning and the streets I drove home on had all be salted. Keep up with 24-hour news 8 – we’re in for some significant winter weather thru early next week.
