May 7th, 2014 turned out to be quite a tornadic storm day for Colorado.

For several hours in the afternoon, there were more than a dozen tornado warned storms, and multiple tornadoes were sighted and reported by trained spotters. One of the tornado chasers, John Hallen, Severe Warning Systems (SWS) indicated he saw around eight tornadoes in eastern Colorado on May 7th, and suspected a number did not get reported as they passed harmlessly over rangeland, but John filmed several Colorado tornadoes at very close range (See pictures).

The Storm Prediction Center had extended a box of 2-5% risk for tornadoes in north-eastern Colorado, and were correct, as tornadoes formed in that area, as well.

Tornadic storms fired early in the day, and started forming around 1:00pm in powerful cells just east of Interstate I25, north of Ft. Collins and right before the Wyoming border. These tornadic storms left nearly a foot of hail behind them, as they slowly migrated eastward. Tornado warned storms also formed near Ft. Morgan, followed by cells in eastern Colorado near I70, and up into northwestern Nebraska, and then fired southward in the Wichita Mountains of Oklahoma, and Texas.
