Jul 16, 2014
Moisture increased over Utah beginning July 14, but the air near the surface remained dry, so gusty winds due to thunderstorms were more common than flash flooding on the 14th. On July 15, this moisture became deeper, and combined with a weather disturbance moving through the area to help produce several flash floods across the state of Utah. A single flash flood was reported on July 16.
