Sunday storm sets mark in unusually wet July
Sunday was the wettest July 28 on record in Grand Junction, with 0.34 inch of precipitation recorded as of 5 p.m., the National Weather Service said.
The previous record for July 28 was 0.30 inch, set in 1987, Jim Daniels, a weather service meteorologist, said.
The rain Sunday increased precipitation in July to 1.12 inches, twice the amount of rainfall that is normal for July.
Rain continued after 5 p.m., and Daniels said the total increased to 0.38 inch.
“The weather pattern is a typical monsoon-type pattern for this time of year,” he said. “We get a semi-permanent high pressure system over the Southwest that is favorable for periods of northward transport of subtropical moisture through the Southwest and into Utah and Colorado.”
The monsoon started around July 4 this year, almost two weeks earlier than usual. On average, its begins July 15, and storms occur on a regular basis for several weeks, Daniels said.
The forecast calls for a 40 percent chance of thunderstorms today with a high of 84 degrees, which would be nine degrees below normal. Skies will clear and temperatures will be back in the mid- to upper 90s later this week.
