Largest Short Term U.S. Temperature Changes



The newspaper clipping attached here is from September 14, 1993 and shows a person cleaning ice and snow off of their car windshield in Gering, Nebraska.
.
What is important to note is the fact that it was 97 F at 4 PM in nearby Sidney, Nebraska on September 12, 1993 and then at 8 AM (the following morning) September 13, 1993 it was 31 F with 4 inches of snow.
