Weather History for February 20
 
1987
A storm system over Arizona spread heavy snow from the Southern Rockies into the Southern Plains Region. Thunderstorms in central Texas produced golf ball size hail about the same time north central Texas was being blanketed with up to 8 inches of snow, closing many schools. (The National Weather Summary) (Storm Data)
1990
Heavy snow spread into southwestern Kansas and the panhandle region of Oklahoma and Texas. Heavier snowfall totals included 12 inches at Boise City OK, 11 inches at Liberal KS, and 10 inches at Spearman TX. Blowing and drifting snow closed roads in the Oklahoma panhandle.
