The first set of storms formed over the KS\/CO border in the early afternoon, but quickly exited the state to the east. Two landspout reports came in from Kit Carson and Yuma, but as of this morning, there was no damage reported. Quite a bit of rainfall accumulated over these counties as well with the back building&nbsp;storms. Totals just over 1.5 inches were estimated by radar. Additional storms set up over the eastern Front Range during the afternoon, which brought a showers and thunderstorms to the Urban Corridor. These storms produced 0.5 inches of rain with hail reports up to 1.5 inches over north Denver. A wind gust of 64 mph, hail up to 1.75 inches and another tornado were reported with a severe storm in Elbert County.
