Lake Effect Snow Warning Ends at 1 PMFebruary 1st, 2013 at 5:02 am by Bill Steffen under Bill's Blog, Weather
Noon Sat. - The Lake Effect Snow Warning ends at 1 PM. There is still some snow south of a line from Holland to Lansing. As of 9 AM, Grand Rapids officially had 3.6″ since midnight and we’re up to 30.6″ for the season with 7″ on the ground. SW Grandville had 15″ on the ground, with 9.4″ new. Muskegon is up to 8″ on the ground, while Lansing east is around an inch. East G.R. had 8.6″ of new snow and 10″ on the ground. Walker added 8.5″ to jump to 13″ on the ground. WOOD-TV downtown had 7″ new, Bangor added 9″ and Howard City reported 2.5′. Bloomingdale checked in with 8″ new, Holland had 5-6″ on the ground. Statewide snow cover: 25″ Munising, 24″ Marquette, Newberry and Charlevoix. Alba had 22″ on the ground with 12″ at Gaylord, 8″ at Muskegon and 7″ at Fremont and Cadillac. From the GRR NWS morning discussion: “…if you like snow, this should be your week”. Good convergence in N. Allegan, Ottawa and Kent Counties now. Still looks good for some significant snow overnight. The new NAM gives G.R. 5.2″ of new snow from midnight to noon (that’s at the airport). It also gives us an inch of snow on Sunday and 1.3″ of snow on Monday. Kalamazoo gets 1.8″ tonight/Sat., 1.2″ Sunday and 1″ on Monday. With a SW Wind, the lake-effect snow is coming right over parts of Kent Co. A “clipper system” is now moving into W. Michigan and that can only enhance the snow will have falling now. So, the coverage of snow will increase after midnight. It’s been dry south of a line from Benton Harbor to Lansing this evening and that area should see some light snow overnight and into the early morning, perhaps a couple inches. We are in a snowy pattern, with clippers and lake-effect snow likely thru Tuesday. We could easily see accumulating snow each of the next 4 days. Nice warming from Lake Michigan today. At 1 PM it was +6 in Milwaukee and +17 in G.R., zero at Green Bay and +13 at Ludington. Northome MN was -39 his AM. Click the image to enlarge. The Lake-Effect Snow Warning continues thru Saturday AM for Mason, Oceana, Newaygo, Muskegon, Ottawa, Kent, Ionia, Allegan, Barry and Van Buren Counties. It’s a Lake-Effect Snow Advisory for Lake, Mecosta, Montcalm, Eaton and Kalamazoo Counties. The Flood Warning continues for the Muskegon River just upstream from the Rogers Dam in Mecosta Co. There are a number of Flood Advisories. The Grand River will come up to bankfull on Saturday morning (the crest has passed Ionia). Check the Grand Rapids NWS discussion. We have already had a foot of snow this week near Allegan, and over 10″ at Oshtemo and Bloomington. Grand Rapids has added 1.8″ new snow today so far. You can scroll down to the radar thread for the usual links. The cold pattern continues with temperatures in the mid teens today, low-mid 20s over the weekend and we probably stay below freezing at least thru next Tues. or Weds. I’ll add more on January weather when the official NWS summary comes out, but snowfall in January was 31.4″ in Muskegon (3.4″ above average!), 17″ in Grand Rapids and just 5.9″ in Lansing (you can see that most of our snow was lake-effect). Twin Lakes in the U.P. had 72.9″ in January. As of 5 PM Friday, Muskegon’s season snowfall is up to 41.5″. Grand Rapids is up to 25.5″ for the season and Lansing has picked up a paltry 10.8″. Snyder Lake in the U.P. reported 37″ of snow on the ground Thursday. The NAM (Car.) would give G.R. another 6.1″ of snow thru Sunday – Holland would get 12.6″ during that time. The GFS gives G.R. about 1/2″ precipitation between now and next Tues. evening and that would come to 8-10″ of snowfall. This light, fluffy snow compacts easily and quickly, so you wouldn’t see 10″ of accumulation out of 10″ of snowfall, but it would be significant. Here’s 84-Hour snowfall off the NAM model and 120-Hour Snowfall off the GFS model (note the snow from the clipper that runs from S. Wisconsin to N. Ohio).
