Overview
|
Multiple rounds of thunderstorms with large hail impacted portions of eastern Wyoming and the Nebraska Panhandle on 15 August 2019, especially in Scottsbluff, NE. A severe thunderstorm developed early in the afternoon near Lusk, WY around 1 PM MDT and continued to move across the region until it finally weakened south of Sidney, NE. Along the way, the storm had a history of producing large hail including golf ball to baseball size hail for much of Scottsbluff around 3:30 PM MDT. The National Weather Service received reports of broken house windows, cracked vehicle windshields, and damaged crops with the hail after providing a 25 minute lead time for the Scottsbluff area. A second round of thunderstorms began developing near Casper, WY around 8:30 PM MDT and continued through the Nebraska Panhandle well into the early morning hours on the 16th of August. One of the thunderstorms dropped baseball size hail 5 miles south of Guernsey, WY around 12:05 AM MDT and was headed towards the Scottsbluff area. For a second time in 10 hours, Scottsbluff was hit with significant hail with sizes ranging from 1.5 to 2.0 inch diameter stones around 1:45 AM MDT with a 44 minute lead time provided by the National Weather Service.
