Thunderstorms elevate the fire threat as impending heat wave builds

Posted
and last updated

Thunderstorms will affect parts of our area until around sunset thus increasing the threat of new fire starts.

Thursday, any storms will be focused towards Southern parts of the Magic Valley. Any moisture leftover will form a few clouds over the Valley floors. Otherwise, it will be mostly hazy and hot by the afternoon.

Our thunderstorm threat will disappear into the weekend but temperatures will soar with Boise possibly touching 108° again!

Boise has recorded 9 days of 100+ heat this summer with 8 of those days in July. The record for most 100° days in season is 27 days in 2022. We are on pace to approach that record in 2024.

The Treasure Valley will be under at an Excessive Heat Warning beginning noon Thursday and lasting through noon Saturday with more heat continuing into Tuesday.

Continue hydrating, wearing sunscreen, and taking shade breaks if you work outdoors.
