Heat in Salt Lake Sets New Record for Summer. A soaring thermometer gave Salt Lake a new heat record for the summer and knocked at the all time July record Monday afternoon. The mercury broke 100 degrees. To be exact, it registered 100.4 degrees at 3 p.m., the highest temperature recorded in Salt Lake since July 27, 1931, J. Cecil Alter, meteorologist of the weather bureau, reported. Climbing steadily during the forenoon, the mercury was decidedly on the upgrade when it touched the high at 3 p.m. and would have gone even higher. Mr. Alter said, had not a cloud moved before the sun, halting the rise. Not since that day in 1931 has the 105 record, established two years ago Monday, come so close to being broke. Monday was the seventeenth consecutive day the temperature has been 90 degrees or higher has been 90 degrees or higher and the thirty eighth day of the summer in which the mercury has been above 90. Although clouds checked the rise of the thermometer, no promise of a rainstorm could be given. A low pressure trough extends over the Rocky mountain region from Canada to Arizona producing excessively warm weather at most reporting stations. Boise residents sweltered in 108 temperature, Pocatello had a 98 reading; Reno, 100, and Spokane, 100. The only rain of consequence was a thunder shower in south western Utah.
