An active and impactful weather pattern is setting up across much of North America through next week. Multiple rounds of severe thunderstorms are expected from the eastern Canadian Prairies, U.S. Plains into the Mississippi Valley, bringing the risk of damaging winds, large hail, and tornadoes. Heavy rainfall may lead to localized flooding from the Northern Plains to the Southeast, while wildfire concerns continue across the Four Corners region. At the same time, summer heat is building, with the East experiencing its hottest temperatures of the season late this week before above-average warmth expands westward during the weekend.
