I was looking at Detroit's top 6 snowstorms, and decided to pull up SFC maps for the dates:
April 6th, 1886 (24.5 inches)
Note: It amazes me how far south and east this storm was. Too bad this is the only data we have!
December 2nd, 1974 (19.3 inches)
Note: QPF-DTX: 1.74 inches, QPF-CLE: 1.89 inches, QPF-IWX: 0.21 inches, QPF-IND: 0.16 inches, QPF-GRR: 0.03 inches, QPF-LOT: 0.46 inches, QPF-BUF: 0.04 inches
March 5th, 1900 (16.1 inches)
Note: The date preceding and following this event showed no significant low pressure. Either the date is incorrect, or this was a significant overrunning event. Temperatures appear to be in the low 30's.
March 1st, 1900 (14.0 inches)
December 19th, 1929 (13.8 inches)
February 13th, 1894 (12.8 inches)
Several of the low centers were well to the south/east of Detroit, and none were deeper than 990mb. The March 5th, 1900 event is interesting given the amount of snow compared to SFC temps and placement of the SFC features. December 2nd, 1974 is also interesting as areas outside of DTW and CLE seen anywhere from 0.04 to 0.41 inches of QPF - in other words, it appears to have been a rather localized band (aided by Lake Erie and Lake Huron?) oriented across that area. CLE added an additional 0.90 inches of QPF, and BUF added another 1.0 inches the next day.
