JULY 29: Record-high maximum temperature, 106; old record, 104 in 1972.
JULY 1-3: A wet period with cool temperatures. Many areas on the 3rd experienced pea- to marble-size hail, due mainly to the intense convection and colder air aloft. Some rainfall amounts (in inches): Alta, 1.28 inches; Coalville, 1.06; Midway, 1.27; Woodland Hills, 1.65; Snyderville, Summit County, 0.63; and Sandy, 0.30.
JULY 18-22: Monsoon moisture moved into the state with weak impulses in the westerly winds that enhanced the thunderstorms. On the 18th, a rainstorm sent Coal Creek to the top of its banks in the Cedar City area, but no damage was reported. A storm hit Oakley with intense lightning and a torrential downpour. On the 19th, Herriman, Salt Lake County, picked up 0.64 inches of rain. On the 20th, parts of Box Elder County were soaked with 0.60 inches in 10 minutes. Residents between Delta and Nephi witnessed a spectacular lightning show during the evening. This storm started fires along the pass between Scipio and Holden, both in Millard County.
On the 21st, lightning struck a young Tooele woman who was riding a four-wheeler west of Tooele. The bolt, which knocked her to the ground, caused burns over much of her body and injuries to her eardrums. Also, on the 21st, parts of Box Elder and Cache counties rocked as three-fourths to 1-inch-in-diameter hail pounded Yost, Box Elder County. Farther east in Hyrum, 1.42 inches of rain and marble-size hail fell within 30 minutes, damaging gardens.

St. George and Salt Lake City reported record highs of 113 and 106, respectively. A cold front pushed into northern Utah during the evening, producing a "gustnado" in Centerville. A gustnado is a microburst which, after it touches the ground, has some circular motion but is not coupled with circulation aloft. One person was lifted up and thrown down to the ground.
