STP 05-31-2016: Scattered Strong Storms, But Fairly Limited Rainfall

Issue Date: Tuesday, May 31st, 2016
Issue Time: 9:20AM MDT

Memorial Day turned out pleasant for most of the state with ample sunshine and warm, but not hot temperatures. Just like Sunday, a round of thunderstorms developed by early afternoon off the higher terrain east of the Divide and spread into the eastern Plains by later in the afternoon. Closer to the mountains, storms dealt with limited instability and very dry air above the surface. The result was limited rainfall amounts, up to about 0.20 inches, and gusty winds after storm passage. However, as storms progressed farther east, deeper moisture meant more instability and fuel for heavy rainfall and other severe weather. Rainfall amounts up to 1 inch per hour were observed in northeast Colorado, mostly notably Sedgwick, Logan and Baca counties. In addition:

• hail up to 1.5 inches was reported in Kiowa County,
• gusty downdraft winds up to 60mph were reported in Kit Carson, Cheyenne, Logan and Yuma counties,
• a 13-minute long tornado was reported in Logan County, near Peetz, around 2:15PM.

In all, 1 tornado and 5 severe thunderstorm warnings were issued across the Northeast and Southeast Plains. Fortunately, all rainfall fell in an orderly fashion and no flooding reports were received yesterday.
