Going back to the previous thread there was a discussion on 12" storms. Here is GRR's numbers on that from their afternoon AFD.
One other point I want to make is, looking at our climate data for
frequencies of a foot or more of snow at Kalamazoo, Battle Creek
and Jackson, getting a foot or more from midnight to midnight is a
rare event. At Jackson, since 1944, there have been only 3 such
events, 16 inches in March 1973 being the greatest, and 14 inches
in in late January 1978 (blizzard of 78 fame) and early January
in 1999. For Kalamazoo, the record as 18 inches in the blizzard of
1978, then there was 16 inches in December 1907, and 13 inches in
mid January of 1979. Our grid point snow total is 12.5 inches for
Jackson, 11.7 for Kalamazoo and 12.3 for Battle Creek. If this
actually happens it would be a top 4 event for all 3 of these
sites.
