Chicago Storm

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.

Someone needs to dig up the baro post in @Thundersnow12's sig for nostalgic purposes, since I'm pretty sure it was about now 11 years ago that things started to go to hell in a hand basket around these parts.

I still remember reading that exact post when he posted it that night. Great memories

Yeah he forgot to add in Battle Creek. The two I know of are Jan 67 with 21.1 and Jan 78 with 18.0 and both are Jan 26th.

Midnight to midnight is a weirdly arbitrary figure though.  I'd just like to see the number of times an accumulation over 12" happens in any 24 hour period.  GHD 1 was the last event I can recall that pulled that off in GRR.  It gets rare as soon as you get east of the major NW flow lake effect belts.  Biggest totals here are mostly synoptic / lake-effect combos that occur over a 48-72 hour period.  It's just not the same as when it comes down heavy all at once.  GHD 1 was special because the bulk of it came down in under 12 hours with a lot of wind to push it around.  Closest thing I've seen to something you would see on the east coast.
