Tuesday will be the hottest day of the year so far, prompting ‘dangerous heat’ watch

Hit the pool, crank up the air conditioning and stock up the freezer: Tuesday is going to be a scorcher, according to the National Weather Service.

Mike Cantin, a meteorologist with NWS – Boise, said the Treasure Valley should see its highest temperatures of the year on July 31. The Weather Service is predicting a high of 103 degrees at its office near the Boise airport, though Cantin warned that Downtown Boise could see slightly higher temperatures, and Mountain Home could reach a high of 106 degrees.

Those highs, coupled with an overnight low on Monday of 70-72 degrees, prompted an excessive heat watch from the NWS for the entire Treasure Valley.

The combination “(sets) the stage for an increased risk of heat-related illness,” the NWS warned. Vulnerable populations like the elderly and children should be careful spending time outdoors, or avoid it altogether. Cantin emphasized the importance of hydrating, and urged people not to leave children or pets unattended in vehicles.

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Be extra vigilant, do not leave children or pets unattended in your vehicle,” the NWS advised.

Cantin said the sweltering heat is the result of an off/on high-pressure system that’s been moving across the region for several weeks. This week, it will move north, sending “core high temperatures” our way.

So far this year, Boise’s highest temperature has been 102 degrees, a mark we’ve hit on July 5, 9 and 24. Tuesday’s temperatures are about 10 degrees hotter than average.

But it’s not all bad news: Temperatures will taper back off into the mid-90s by Thursday, Cantin said. They’ll likely hover around 100 degrees into the weekend.

“Late July into August is our warmest time of the year. I don’t think we’ll be out of the woods until mid-August,” Cantin said.
