Radar and Links for Winter StormJanuary 4th, 2014 at 12:18 pm by Bill Steffen under Bill's Blog, Weather
Snow already breaking out north of a line from S. Haven to Big Rapids. Heavier snow coming farther north into NW. Allegan, Ottawa, Muskegon, Kent – more to follow, keep coming back to the blog. Lake effect and synoptic storm snow already cranking up in Allegan, Ottawa, Kent, Muskegon, Oceana, Mason, Newaygo and Lake Counties. Drifting a factor. Check out the NAM model 84-hour snowfall (large over 18″ area!) and the GFS 120-hour snowfall (5-day totals of 16-18″ between G.R. and Indiana). Keep watching WOOD-TV and coming here to www.woodtv.com for the latest. I anticipate lots of closings/cancellations over the next several days. EUROPEAN model has 0.50″ precip. for G.R. by Monday AM – even at a conservative 20-1 ratio, that’s 10″. Total of 0.82″ thru Thurs. AM would be +16″!!
Shiverin’ Snowman!! Morning model data really rampin’ up the snow totals: NAM (Caribou) snow totals thru Tuesday (keep in mind these are often overdone, but even if half this, with strong winds and drifting, this will be a major snow event: S. Haven 24.7″, Holland 22.4″, Lansing 19.6″, Grand Rapids 19.1″, Jackson 15.5″, Pontiac 15″, Mt. Pleasant 13.4″, Muskegon 10″, 8″ Big Rapids, 5″ Cadillac. The GFS (caribou)…first number is thru Tues., second number is snowfall for Weds. to Thurs. AM: Grand Rapids 9.3″ + 2.8″, Kalamazoo 9.7″ + 3.3″, Jackson 9.2″ + 3.5″, Ludington 3.7″ + 1.2″, Muskegon 7.5″ total, Cadillac 2.2″ + 0.4″. Big Rapids 3.2″ + 1.3″. The NAM (caribou) only takes G.R. to a low temp. of +2 Monday evening (with a 17 mph wind). The wind stays west off Lake Michigan. The wind goes WSW at Muskegon and the temp. at Kalamazoo goes to -10 (with a 23 mph wind), so Monday PM into Tuesday, the coldest wind chills will be southeast of G.R. where the wind is not coming across Lake Michigan. +2 deg. with a 17 mph wind is a wind chill of -18 and -10 with a 23 mph wind is a wind chill of -37 – Big Difference. Also peak winds today occurring now…the wind will ease back a bit as the afternoon/evening goes on. NAM/WRF has big snow dump south of a line from Muskegon to Saginaw area. The combination of synoptic snow plus lake-effect means huge snow dump somewhere in Allegan/Van Buren – maybe even into Kent, Barry, Kalamazoo. Coldest air in 20 years? Up to 16″ of snow in 24 hours in the U.P. – 52″ of snow on the ground at Painesdale. ICE expanding rapidly on the Great Lakes. Cold safety tips.
Also: Coldest NFL football games. Wind Chill Forecast for Green Bay at 1 AM Monday -38!! 11 deg. and flurries for Macon GA?? Frozen Nation! Minneapolis NWS says: “”Wind chills colder than -50F can cause exposed flesh to freeze in only 5-10 mins.” Major volcanic eruption in Indonesia. VERY COLD, then a warm-up for a few days – then back to the deep freeze. Cold reloads!
