On Thursday, June 5th, the Storm Tracker 5 Weather team made a forecast which called for severe thunderstorms across parts of SE Wyoming, Southern portions of the Nebraska Panhandle and Northern Colorado. On Friday, June 6th, the atmosphere quickly destabilized allowing thunderstorms to quickly develop, most of which become severe producing large hail, gusty winds and even a few tornadoes.
Multiple reports of a tornado in SW Kimball County came in between 1:30 PM and 2:00 PM as a Supercell thunderstorm quickly sprung up. Thanks to decent wind shear and high instability, a tornado was able to develop. There have been no reports of damage from the tornado.
The Supercell would also produce 1.5" diameter hail in the small town of Bushnell, NE around 1:30 PM. Early in the evening, additional thunderstorms would move through Southern Laramie County bringing hail and rain to the Cheyenne area.
A few more tornadoes also developed as storms rapidly developed in Northern Weld County near Grover, CO. The storms would quickly move east producing a line of severe storms that would stretch from central Nebraska to southeast New Mexico.
In the Tri-State Region, there was a total of 13 unconfirmed Storm reports including 8 Tornado reports and 5 Hail reports. Most of those tornado reports are likely duplicates of the same tornado.
