I remember a huge storm that came rolling out of Canada that year, but I remembered it happening earlier in the year. My mom was working in the snack bar at the mid-high (a band parents' fundraising venture), so I went to see her while I was between classes at OU. When I went in, it was shorts weather, and when I left an hour later, everything was icing over. Seems like it set some kind of record for a temperature drop.December 21st - 23rd, 1989. Kansas City set an all time record low of -23 F. That's with records going back to 1893. OKC was a record -8 F going back to 1948.
