Saturday saw near-record rainfall in Boise, adding to an already soggy month
Halfway through June, Boise had already seen more precipitation than it typically does during the whole month, adding inches of precipitation to an already soggy month..
As of June 14, the National Weather Service’s Boise branch had measured 2.38 inches of precipitation at its office near the Boise Airport. That was boosted by near-record rainfall on Saturday, when Boise saw 1.21 inches of rain, second only to the single-day June rainfall record of 1.91 set on June 12, 1958.
A storm the previous weekend dropped snow at Bogus Basin and several other parts of Idaho and rocketed the Treasure Valley past its average June precipitation total in just over a week. In an average June, Boise sees .69 inches of rain for the entire month.
Still, it’s not likely we’ll surpass the 3.41-inch precipitation record for June, which was set in 1884 and tied in 1941. Instead, Saturday’s big storm bumped June 2020 into the top three wettest Junes on record, according to National Weather Service data.
The unusual amount of rainfall comes during a year that’s already particularly wet, National Weather Service meteorologist Dave Groenert said. Boise has received at least an inch of precipitation each month this year, bringing the year-to-date total to 10.71 inches by Sunday. Typically by the same date, the region has received less than 7 inches of precipitation.
There’s still a slight chance the Treasure Valley will see more precipitation on Monday and Tuesday, while the forecast through the rest of the week looks dry, according to National Weather Service forecasts. Cool temperatures in the 60s will continue through the week and rise to the mid-80s by next weekend.
