Monsoonal moisture returns to valley
The monsoonal moisture pattern that delivered two days of rain to the parched Grand Valley last week has returned, with most of western Colorado and eastern Utah under a flash flood watch for the next two days.
The National Weather Service issued the watch for the region through midnight Wednesday.
“Scattered to numerous thunderstorms with heavy rain are expected over the watch area, developing this afternoon and continuing through this evening. With a moist airmass in place, the threat for heavy rainfall will continue into the overnight hours. Another round of afternoon thunderstorms is expected on Tuesday afternoon lasting through midnight Wednesday,” the Weather Service posted on its website.
Here in Grand Junction, the forecast calls for anywhere from a 30 to 50 percent chance of rain this afternoon through Wednesday. Today’s high is expected to top out at 92 degrees, then drop off into the upper 80s Tuesday and Wednesday.
Rain last week brought July’s total to 0.59 inches, which is 0.18 inches above average month-to-date. But Grand Junction’s year-to-date precipitation of 3.45 inches remains well behind the average of 4.7 inches.
