Dangerous Heat and Storms Across the U.S. - 08-08 to 08-10
Updated Fri Aug 7th 2026, 1:16pm PDT

This weekend promises some intense weather, especially for those in the Western U.S. where dangerous heat is expected, extending to the Central U.S. next week. Meanwhile, the Southeast will continue to deal with unsettled weather. Additionally, the Pacific Northwest and Intermountain West face poor air quality due to wildfire smoke. Be prepared for these conditions and stay informed.

Western U.S. Heat Wave

Starting Saturday and lasting through the weekend, the Desert Southwest and Intermountain West will experience extremely hot temperatures, reaching over 110°F in some places. This is significantly warmer than usual, potentially setting new records. The hot and dry conditions will increase wildfire risks and might lead to rapid fire spread. Smoke from these fires will also contribute to poor air quality, so stay indoors when possible.

Weather East of the Rockies

The North-Central U.S., Northeast, and Mid-Atlantic will experience a series of storms this weekend. These storms might bring heavy rain, possibly leading to flooding in localized areas. Be aware of potential hail and strong winds, especially in the Northern/Central Plains and parts of the Midwest and Mid-Atlantic.

Southwest Storm Activity

The Southwest will continue to see daily thunderstorms due to monsoonal moisture. These storms might bring heavy rain and isolated flash flooding, so stay alert when venturing out.

Pacific Northwest and Intermountain West Air Quality
