There are more triple-digit temperatures in store for the Boise area this weekend, and residents should get used to it.

The light at the end of the tunnel is just more sunlight, although by Tuesday or Wednesday, highs might stay below 100, according to the National Weather Service.

“It is going to be hot,” meteorologist Josh Smith said in a phone interview.

Smith said Treasure Valley residents can expect a high of 105 degrees on Friday, with it getting even hotter Saturday, for a high of 107.

Sunday is expected to cool down slightly, with a high of 102, Smith said.

The weekend temperatures will be similar to last weekend, when Boise saw highs of 101 and 107 — and it won’t cool down, Smith said.

“This stretch is going to be longer,” Smith said. “We’ll be maintaining those warmer temperatures at least until Monday, when we’ll be around 100.”

High temperatures on Tuesday and Wednesday are expected to be in the 90s.

Boise’s record streak of triple-digit temperatures is nine days, the Idaho Statesman previously reported. That was thought to be in jeopardy with this heat wave, but it looks as if that won’t happen.

The cool water and shade along the river banks shielded the children from the sun and heat. The camps run Monday through Thursday every week until mid-August.

Early mornings will be the time to be out and about this weekend, Smith said. But even then, temperatures won’t be much below 80 degrees.

“It is going to be the coolest part of the day, but it’s not going to feel very cool,” Smith said. “With the low 70s here in the valley, it’ll definitely be cooler than the afternoon, but it’s not going to be as cool as we’ve experienced in the last few days.”

The peak temperatures are expected between 3 p.m. and 5 p.m., which is typical for Boise.

If Treasure Valley residents want to escape the triple-digit heat, they should head to the mountains. Temperatures at higher elevations should be in the low 90s, Smith said. He predicted that McCall would see a high of 93 this weekend.

“That’s 10 to 12 degrees cooler than here, but unless you’re going up to the Panhandle or towards Washington, there’s really no place in Idaho where it’s going to be significantly cooler,” he said.

Smith reminded people to be aware of symptoms of heat stroke and exhaustion, such as rapid breathing and nausea; to stay hydrated; and to not leave children or pets in hot cars.
