Thunderstorms early Monday morning were the cause of wind gusts ranging up to 60 mph near Mountain Home, said Korri Anderson of the National Weather Service.
The storms are expected to continue on Monday from noon to midnight near the Payette National Forest and the Owyhee Mountains. The National Weather Service issued a red flag warning — a notice of an increased risk for fires — because of the storms, with possible wind gusts of up to 55 mph with a slight chance of hail. Low humidity and Monday’s hot temperatures also factored in to the warning, according to the National Weather Service.
Boise residents saw record-breaking temperatures over the weekend, and will continue to see above-average temperatures throughout the week.
Sunday broke the record for the hottest June day, reaching 110 degrees. The last June day to come close was in 1940 on June 19, when it got up to 109 degrees, according to Bill Wojcik, meteorologist with the National Weather Service.
Never miss a local story.
With overnight winds, Monday is expected to only see a high of slightly more than 100 degrees. The rest of the week will hover around 99 to 101 degrees, but not top former records, Wojcik said.
There’s always a chance it could cool down much more in upcoming weeks. Typically this time of year sees highs in the 80s and low 90s, he said.
Air quality has also taken a hit.
The Idaho Department of Environmental Quality issued a yellow air quality alert for Sunday and Monday. That means residents of Ada and Canyon counties can’t burn outdoors, and drivers are recommended to limit their driving time. The air quality gets bumped up to yellow whenever the air quality index is more than 60. By Monday it’s expected to be at 63, according to the DEQ.
