From the Longmont Times-Call:
Matt Kelsch, a meteorologist at the University Corp. for Atmospheric Research, said Boulder, as of Monday, had received 4.99 inches of rain this month. The record was set in July 1919 with 7.46 inches, followed by the second-wettest July in 1965, with 5.2 inches. The thunderstorms also cooled off the city enough to keep this July from breaking heat records — unlike Denver, which is expected to close out its hottest month ever recorded.
