We weren’t expecting anything significant on June 21st. However, as often happens in the upslope regions of Colorado combined with terrain features, a decent supercell formed north of Colorado Springs along the Palmer Divide. Good directional shear due in part to strong easterly winds helped the storm to organize and rotate. As the cell approached the town of Kiowa, the low levels started spinning strongly. You can see a hook forming visually and rotate pretty rapidly. A tornado warning was issued by the NWS and soon an area of rotating debris was seen under the hook area of the storm. This weak tornado only lasted a couple of minutes.
As the cell moved further east, it encountered less surface moisture and instability, which caused it to steadily weaken and eventually dissipate east of Limon. Several other storms initiated in the cold side of the first cell’s outflow and never could really intensify for long periods. A fun chase and right in our backyard.
