Dangerous, prolonged heat is ongoing in the Mid-South to Mid-Mississippi Valley and heat expands into the Northeast for a brief period today. Widely scattered instances of flash flooding due to heavy rains are forecast from northeast Kansas to much of Indiana. Scattered strong to severe thunderstorms are possible across parts of New England, northern Mid-Atlantic, and North Dakota. Read More >

Overview

A very unstable airmass was in place ahead of a weak mid-level disturbance that moved into the area. Temperatures surged into the upper 80s to lower 90s within a very moist airmass characterized by tropical-like dewpoints in the mid to upper 70s. Scattered thunderstorms rapidly developed around 11am near a remnant outflow boundary from earlier convection. The storms formed into several clusters that moved southeast across portions of southeast IL, southwest IN, and much of western KY. The main threat was damaging winds, with a few scattered small hail reports as well.
