Temperatures are headed north of 100 Wednesday afternoon in Boise — it was 99 just after 4 p.m. — but things will cool down for a few days before the next multi-day heat wave hits, according to the National Weather Service.
The Idaho Department of Environmental Quality issued a yellow air alert, warning Valley residents about diminished air quality. Yellow is the moderate category, and those in sensitive groups — children and the elderly — are encouraged to limit time outdoors. All open outdoor burning is prohibited in Ada County and the cities within, as well as the incorporated cities within Canyon County.
The weekend will be warm, but not blistering. Highs Thursday through Saturday will be in the low-90s, forecasters say.
But things heat up again on Monday, which is expected to hit 101. Tuesday and Wednesday will even warmer, with models showing 103 and 102, respectively.
“Water park weather? You bet,” meteorologist Valerie Mills said.
