Read the full account →Anomalously deep moisture was present across southeast Utah and southwest Colorado on the afternoon of June 4th. Enough sunshine had gotten through during the morning hours to create afternoon instability of 500-1000 J/Kg, more than enough to produce some strong storms.
Read the full account →Substantial monsoon moisture remained over the area as high pressure drifted east over the Plains. As a result, widespread showers and thunderstorms developed with many storms producing heavy rain.

Read the full account →A pattern developed by late May with sufficient moisture and forcing to yield scattered showers and thunderstorms almost every day, generally from the afternoon on into the early evening hours. Some of these storms were strong, yielding damaging wind gusts and hail.
Read the full account →Heavy rains produced flash flooding which destroyed large sections of three paved county roads and flooded the football field at the Monument Valley High School. Combined destruction of the paved roads was about one mile in length.
Read the full account →Thunderstorms continued across Utah for the last week of July, with many storms producing heavy rainfall. This led to flash flooding in many locations, including a particularly damaging flood in Salt Lake City.
Read the full account →Monsoon moisture increased across the region as the area of high pressure shifted towards the Southern Plains. The abundance of moisture fueled numerous showers and thunderstorms during the afternoon and evening hours. Storms were slow moving and produced heavy rain.
