Severe Thunderstorms and Heavy Rainfall Across the Midwest into the Great Lakes Region; Significant Heat in the Southwest

Strong to severe storms may produce damaging winds, isolated hail, and a few tornadoes from the Midwest into the lower Great Lakes. These storms may also produce areas of heavy rain and flash flooding. Significant heat will continue across parts of the Desert Southwest into western Texas and north Alaska. Dangerous heat will also build into the Eastern and Central U.S. and continue into next week. Read More >
