I’ll leave radar up again. We do have a chance of light snow. The European model would give G.R. about 1/2 to 3/4″ of snow today/tonight. The main feature today will be the stiff west wind. The NAM model takes it to 20-23 mph around noon. That will cause some drifting and maybe even blowing snow. We could easily see gusts up to 30 mph (35-40 mph at Lake Michigan. For Grand Rapids, the European model (overnight) has about 1/2-3/4 inch of snow Monday night, a very cold -5 to -15 Tues. morning (the NAM (caribou) gives G.R. +9 – quite a difference) and about -4 Tues. night. We get flurries Tue. and about 1 to 1 1/2 inch of snow Weds. PM/Night, then dustings to maybe an inch Fri. and Sat. No big storms, but a cold week overall. The 84-Hour NAM snowfall forecast has a nice 6″ lake-effect snow for Berrien Co. The GFS goes out 120-hours and shows more snow in the lakeshore counties. The European has the coldest periods Tues. to Thurs. of this coming week and Sunday to Tues. AM the following week with this Tues. and the 27th as days when cold spots could hit -10 to -15. This is VERY dependent on cloud cover and light or calm winds not coming off Lake Michigan.
Season snowfall: 29.0″ Battle Creek, 33.3″ Lansing, 56.4″ Grand Rapids, 60.3″ Lansing (WMU), 62″ Oshtemo, 67.1″ Holland, 67.2″ Muskegon,
High temps. Saturday – on the warm side it was 83 in Los Angeles, 77 in Brownsville TX, 53 in Great Falls MT and 54 in Denver. On the cool side, the high was 55 in Orlando, 56 in Tampa, just 45 in Atlanta and 18 in Pittsburgh. A band of 2-6″ of snow passed south and west of us…from MN, eastern IA into N. Illlnois and Central Indiana. The snow caused a fiery crash closed I-65 in Indiana Sat. PM. There were a few winter thunderstorms in New Jersey. San Juan Puerto Rico had a high temperature of 91. Much of Russia has been unseasonably mild this month (relative to average, of course). Moscow is 16 degrees warmer than average for Jan. 1-17, though they’ll go below average this weekend and Verkoyansk in Siberia has had high temperatures of -59, -58 and -60 over the past 3 days.
NFL Weather: Sunny and warm in Denver (3 pm start) with a high near 60 (average is 44). Seattle (6:30 pm start) looks cloudy and maybe a little foggy with temperatures in the low 40s. Winds shouldn’t be much of a factor in either game, W-SW at 5-15 mph in Denver and N-NW at 5-10 in Seattle.
Model update: We’ll reach the mid 20s today, most areas get a dusting of snow…we have a nice southwest wind, but it was no warmer in St. Louis or S. Indiana on Friday, so it’ll be a cool south wind. Sunday gets wind…the NAM goes up to 22 mph in the late morning and the GFS plot is a similar 22 mph. Monday the cold air starts coming in…we may peak in the low 20s around early afternoon. The NAM (caribou) has a low temp. of 7 for G.R. Tues. AM, the GFS plot is 3 above about mid-morning. The GFS plot would have highs of around 11 Tues. PM, 12 on Weds. and 14 on Friday. Low temperatures will vary, depending on cloud cover and if the wind is coming off Lake Michigan Temperatures slowly moderate a bit starting late Friday, but more Arctic air keeps temps. quite cold Sunday and Monday the 26th and 27th. The European model would give us at least a dusting of snow each day with about 1-3″ on Weds. and another 1-3″ on Friday. The Euro. would give G.R. highs of around 19 on Monday, 11 on Tues., 13 on Weds. and 16 on Thurs. It takes G.R. to -13 Tues. AM and -4 Weds. AM and near zero Thurs. AM. For Sunday the 26th it gives G.R. a high near zero and a low Monday AM of -18!! It’s tended to a be a little low, but this is going to be a REALLY cold shot and longer than the Jan. 6-7 shot of Arctic air. The Sunday 2/2 GFS still looks mighty cold.
