Temperatures in Boise and parts of Idaho are expected to reach near-record highs Wednesday as a brief heat wave moves through the region this week, according to the National Weather Service in Boise.
Residents can expect dry and sunny weather as a high pressure system pushes temperatures into the 90s in early fall. The high in Boise is expected to be 92, with temperatures expected to reach at least the mid-80s the rest of the week.
While these types of weather systems are not uncommon as summer turns to fall, temperatures in the 90s are a bit high, said Jarrett Rogers, a meteorologist with the National Weather Service.
The record temperature for Sept. 25 in Boise is 95, set in 2015, according to NWS data.
“It’s not unusual to have high pressure systems … as we’re still coming out of summer weather,” Rogers told the Idaho Statesman. “This one just happens to be unusually strong, and because of that, we’re seeing quite a bit of unusual warmth with it for the end of September.”
He said temperatures should return to the 70s, normal for this time of year, by next week. He also reminded Idahoans to use adequate sun protection on Wednesday.
