Monday 12/26
Quick note: The NWS afternoon discussion looks pretty good to me. Not much snow here, and with temperatures at or above freezing, most main roads will just be wet. The time when we could see slick spots may be Tuesday evening as temperatures fall below freezing. Watch me on the news tonight. Click to enlarge the graphic. This is snow cover across the Lower 48 states on Christmas morning, or who had a White Christmas. 30.2% of the Lower 48 states had a snow cover Christmas morning. This compared to 50.2% in 2010 and 63% in 2009. The last years with less snow than this year were 2006 and 2005. Most of West Michigan had a trace of snow on the ground (less than 1/2″). The sites in West Michigan reporting an inch of snow on the ground (or rounded up to an inch) were Grandville (Bill Marino of the NWS reported this, I believe), 3 NW Walker, White Cloud and Scottville. If you had an inch of snow on the ground Christmas morning, leave a comment and let us know. Other snow depths Christmas morning: 2″ Sault Ste. Marie, 3″ Gaylord, E. Jordan, Mancelona and Detour Village, 5″ near Beulah, Ironwood, Newberry and the Marquette NWS. Ahmeek had 6″ on the ground, 7″ at Mohawk in the Keweenaw and 8″ at Grand Marais and Twin Lakes (where they report 37.5″ of snow for the month of December so far). In the Lower 48 states, the warmest temperature on Christmas Day was 85 at Fort Myers FL (Key West had a morning low temperature of 74) and the coolest was -15 at Clayton Lake, ME and it was a chilly 14 at Marfa, Texas (colder than it has been in G.R. this month). The cold is starting to build up in Alaska again. Fairbanks was down to -27 Christmas morning and Nuiqsut had a frosty -37. Valdez is up to 53″ of snow on the ground and Kotzebue has 50″ (with a high of -9 on Christmas Day). Here’s snow cover in the N. Hemisphere…lots of snow in Russia/Canada…spotty across the U.S. and Western Europe. The South got some much needed rain: 2.06″ Shreveport LA, 1.54″ Meridian MS, 1.53″ Jasper TX, 0.92″ at Houston. We’ve gained one minute of daylight since the Winter Solstice on the 22nd…whoopee. Today will be the 16th day this month that the temperature has hit 40 or better in G.R.! It did not reach 40 during the first 29 days of December last year. Extras: You’ve heard of storm-chasing…how about aurora chasing. 101 mph wind gusts in Scotland and a tropical storm is threatening Australia. MODEL DATA: The 00Z run of the GFS gives G.R. only 0.05″ of precipitation around daybreak Tuesday, another 0.06″ Thursday PM and another 0.10″ Friday and Friday night. That would be a mix of rain and snow. The European gives G.R. a healthier 0.34″ Tues. PM with 850 mb temps. of -3 to -4, so that could be mostly snow. Then 0.03″ on Thursday (rain or mix?), and .27″ Friday night/Sat. AM…maybe a mix to snow. The models show a shot of light snow then lake-effect snow with some colder air on Mon. 1/2 and a pretty windy and cold day. I’ll add more when the model data gets in during the early afternoon, so check back. In the meantime, check the Reindeer Cam, Snowman Cam (look for deer), Santa Cam, the South Pole, and Caribbean webcams.











UPDATE: A mix of light rain and snow will gradually change to all light snow, then taper off to scattered flurries early tonight. Roads will have slippery spots SE of G.R. It’s still
