Heat Across the Center of the Nation; Severe Thunderstorms Across the Great Lakes and Ohio Valley

Heat expands across the Desert Southwest, Plains, Mississippi Valley and Midwest into Monday. Fire weather concerns continue for portions of the Intermountain West. Active monsoonal moisture fuels thunderstorms over the Southwest with possible flash flooding. Tropical cyclone Fausto in the Pacific, should weaken as it approaches Hawaii; Dangerous surf, swells and rip currents are expected. Read More >

A Heat Advisory for portions of the area remains in effect through Tuesday. Highs will reach the mid-90s with heat index values peaking between 103-107°. Stay hydrated, limit afternoon outdoor activity.
A storm complex will move southward into the area producing strong, gusty winds and a low-end threat for damaging winds tonight. In addition, locally heavy rainfall may occur in a few locations which could produce areas of localized flash flooding. The storms are expected to enter southern Middle Tennessee counties around 11 PM, and push into northern Alabama around midnight. The storms may exit the area as early as 3 AM, although exact timing remains uncertain.
Low chances of strong to severe storms exist on Monday and Tuesday. Storm chances will be highly contingent on what happens upstream so make sure to check back for updates.
