Hard to find much on the midwest Halloween '91 storm, as most of the attention was on the one out east at the same time.
Here's about all I can find, but you can see satellite loops, regional radar, and surface maps from Oct 30/ Oct 31/ Nov 1.
34:25 min mark for Oct 30th
49:20 min mark for Oct 31st
1:07:10 hour/min mark for Nov 1st- the peak of the Midwest blizzard.
