DISCUSSION

Issued at 155 AM MDT Sat Jul 11 2026

Weekend still looks very dry. Although the models are trying to suggest a rogue storm possible Saturday over the hills south of Burley and also Sunday across the eastern highlands and central mountains. The issue is the position of the center of the ridge which has the very dry air with the upcoming monsoon moisture that will work up from the south as the ridge moves east. Probability of actually developing a dry storm is probably 10 percent or less. Monday continues to look dry as well, although suspect we'll be seeing similar types of issues once we start getting into the time frame of the higher resolution models. The weekend still looks very hot with near record or record highs. Upper 90s to near 100 is likely for most lower elevations today, with upper 90s to lower 100s on Sunday, and upper 90s to around 100 or so on Monday. Heat advisories and warnings remain in effect for most locations with the heat risk indicating that the only real reprieve is from Ketchum up to Stanley. It will be breezy over the weekend. Most of the winds are from the central mountains into the upper Snake Rive Plain on Saturday and more areawide on Sunday. On one hand, the breeze might make someone feel a bit cooler. But on the other hand, one could potentially dehydrate faster.

The monsoon push arrives Tuesday. The added clouds/storms will help keep highs a touch lower. But temps will remain solidly in the 90s for next week, especially in areas that dont see appreciable clouds or storms.
