...1992... A big late season snowstorm over northeastern Nebraska came to an end. 9.3 inches of snow fell at Omaha. Of interest was the fact that 13.3 inches of snow had fallen in Omaha up to November 23, 1991 and then after that only 1.7 inches had fallen until this snowstorm, so most of the 24.3 inches measured during the winter season did not fall in the winter at all, but in the autumn and spring.

Brownsville checked in with 14 inches and Offutt Air Force base measured 12 inches. 2 inches of snow fell at International Falls, Minnesota on this day.
