UPDATE: Monday’s heat ties 125-year-old record in Treasure Valley; sweltering conditions expected through week

A hot week got a record-tying start in the Treasure Valley Monday, matching a record that has stood since 1890.

Shortly after 3 p.m. Monday, Boise’s temperature hit 96 degrees, the National Weather Service reports.

Tuesday is expected to be even hotter -- 97 degrees -- but that would fall 1 degree short of the record 98 degrees registered in 1952.

“It’s going to be really close tomorrow,” meteorologist Stephen Parker said.

Mountain Home and Ontario, Ore., are expected to hit records on Tuesday, with forecasts of 98 and 99 degrees, respectively.

Boise’s high temperature is expected to drop to 91 degrees on Wednesday but stay above 90 until the weekend, when a Saturday high of 88 degrees is expected to deliver slight relief, the Weather Service reports.

Parker said it will feel like a dramatic change in temperature for Boise residents because of the cooler than normal weather that preceded this June heat wave.

"We're going to be about 10 degrees above normal for the rest of the week," he said.

With rising temperatures it's important for residents to keep safety in mind. People shouldn't leave their children or pets in cars. Neighbors should check in on elderly neighbors who don't have air conditioning, Parker said.
