forecast probabilities for the Tuesday

This is HPCs forecast probabilities for the Tuesday PM/Tuesday Night storm. Looks like another solid 4-8″ or 5-10″ band, with mixed precipitation on the southern edge from GRR south. We’re already at 40.5″ of snow for the month in GRR, the 3rd highest amount of snow ever in the month of December (average is 18″). Muskegon is up to 55.6″ for the month. Muskegon still has a long way to go to reach their monthly record of 102.4″ in Jan 1982. I remember that month…we had blizzards three weekends in a row in January. This is also on track to be the cloudiest month EVER! We’ve had only 6 hours and 43 min. of sunshine this whole month. That’s 3.5% of possible sunshine. The cloudiest month ever in GRR was Nov. 1992 with 5.1% of possible sunshine. Temperature-wise here’s how far we are below normal this December: Grand Rapids: -4.1 deg., Kalamazoo -5.6 deg., Chicago -7.1 deg. Official snow depth: Grand Rapids 13″, Muskegon 21″, Wellston in Manistee Co. 29″, Alyeska AK. (summit) 104″ (272″ for the winter so far). Verkoyansk in Siberia had a HIGH temperature of -71 deg.
