Click the pic. to enlarge…this is from daughter #3. We wound up with 34.7″ of snow in Dec. in G.R. That looks like the 7th snowiest Dec. ever for G.R. (and 9th snowiest for Muskegon). That was 12.8″ above average and compares to just 7.2″ in Dec. last year. We had measurable snow on 20 of 31 days, and an average snow depth of 5″. The greatest snow depth was 10″ in G.R. on the 18th and 15″ in Muskegon on the 25th. Precipitation totaled 2.7″ or 0.2″ above average. We had only 16.4% of possible sunshine. There were 14 days with no sun, 21 days with less than 10% sun and only 4 days with more than 40% sunshine. Those 4 days (the 2nd, 16th, 24th and 28th) accounted for 63% of the total minutes of sun for the month. The days are short in December. The total minutes of sunshine for the entire month (2775) was only slightly above the total minutes of sun we had in just 3 consecutive days from July 11-13 (2692). The average temperature was 26.1 or 3.1 deg. cooler than average. The warmest was 59 on the 4th and the coolest was +3 on the 16th. The biggest weather story was the ice storm of 12/21 that affected 19% of Consumer’s Energy Customers. Hardest hit was an area from Barry Co. to the Flint area. At one point 570,000 customers were without power in Southern Lower Michigan. Heavy snow on the 23rd, falling at the rate of over 2″ an hour, brought up to 18″ of snow to parts of Muskegon Co.
