Heat wave could threaten all
Key Points:
- A heat dome will bring record-breaking high temperatures starting this weekend to the northern Rockies and Northern Plains, then spread intense heat and humidity across the Midwest and East next week.
- Extreme heat watches and warnings are in effect from Nevada to northern Minnesota, with triple-digit highs expected through early next week and some areas potentially exceeding 110 degrees.
- Several national parks, including Glacier, Yellowstone, Grand Teton, and Utah's "Mighty 5," will experience much hotter conditions than usual, posing risks for outdoor visitors.
- The Midwest and East will see temperatures rise into the 90s and possibly near 100 degrees by midweek, with minimal overnight cooling, increasing the risk of heat-related illnesses.
- A strong cold front may bring relief to the Northeast by mid to late week but could also trigger severe thunderstorms with damaging winds ahead of the front.
