Salt Lake City's blistering 100 degree temperature on Friday wasn't a record-breaker, but it was close. The temperature was only three degrees shy of the all-time July 22 high of 103, set in 1937, said William Alder, the National Weather Service's chief forecaster in Utah.

However, Friday may have been a record day for the most cities, 10, reporting temperatures of 100 degrees or more.Thirteen Utah stations reported near-record-breaking temperatures: West Valley City hit 102; Milford, Beaver County, 99; Tooele 100; Moab 107; Harrisville, Weber County, 112; St. George 107; University of Utah 100, Roosevelt 102; Delta 102; Green River, Emery County, 105; Kanab 100; Ogden 99; and Orem 99.

Alder said the thermometer has already hit 100 degrees six times this summer. On average, Salt Lake City only hits 100 five times during the entire summer season, once in June, three times in July and once in August.

However, relief may be on the way. Alder says widely scattered thunderstorms may erupt during the weekend and continue through Pioneer Day and the Pioneer Day celebration July 25.

Rain showers will cool temperatures 2 or 3 degrees, but showers are expected in the late afternoon and early evening hours, so the Days of '47 parade and most July 25 celebrations will not be affected.
