More rain could put valley in top 10 for wettest Mays
The rain that soaked the Grand Valley last week helped elevate precipitation for May to above-average levels, and another round of showers and thunderstorms forecasted for this week could push this month into one of the 10 wettest Mays on record.
Three-quarters of an inch of rain was recorded at Grand Junction Regional Airport over a four-day period last week, a significant amount considering that the average precipitation for the month is 0.7 inch, according to the National Weather Service.
The rain bumped up the total precipitation for May to 1.22 inches, which is within a rainy-day’s distance of the 10th-wettest May on record. That occurred just two years ago, when 1.60 inches of rain fell. The all-time record is 2.74 inches, which occurred in 1906, according to Travis Booth, an intern with the National Weather Service.
After a dry start to the year, above-normal precipitation in April and May gave Grand Junction a total of 3.43 inches through 5 p.m. Sunday, about a quarter of an inch below the normal amount, Booth said.
Meteorologists are calling for more rain in Grand Junction and snow in the higher elevations of western Colorado to start the week. There’s a 40 percent chance of rain today and Tuesday, with the high around 71 today and 66 Tuesday.
Last week’s system “was stronger and slower-moving,” Booth said. “This one is expected to be more progressive.”
A warming and drying trend is expected to boost highs to around 80 degrees by the end of the week.
