Boise high hits 101 Wednesday, but expect cooling trend

After topping the 100-degree mark for the first time this year, Treasure Valley weather will gradually cool off through the weekend.

Wednesday’s high in Boise was 101 degrees, breaking the record of 96 degrees set last year, National Weather Service meteorologist Stephen Parker said.

But a cool front moving in overnight is expected to low temperatures significantly, he said. But Thursday and Friday’s forecast highs — 84 and 82 degrees, respectively — will still be several degrees above normal, Parker said.

That will change over the weekend, with a forecast high of 72 degrees — 8 degrees below normal — for both Saturday and Sunday, he said.

Gusty winds were expected to move in overnight Wednesday but mostly subside by Thursday, he said.

Meanwhile, the Department of Environmental Quality reports Wednesday as another day of yellow, or moderate, air quality. The ozone levels jumped up a bit due to warm weather, according to DEQ.

Sensitive populations, including children, the elderly and people with lung and heart conditions should limit their outside exposure. And all residents should try to reduce their driving time. Outdoor burning is prohibited within Ada County, according to DEQ.
