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

Two rounds of severe storms brought large hail, strong winds and brief heavy rainfall to portions of northeastern Wyoming and southwestern South Dakota. Storms began over the Black Hills in the afternoon hours, with large hail reported in Piedmont, Nemo, Black Hawk, Hart Ranch, and Hermosa. A second round of severe storms moved through in the evening hours as an upper level system combined with a cold front. These features allowed storms to develop in a line and move east through most of northeastern Wyoming and western South Dakota. Strong winds were associated with this line of storms with wind gusts exceeding 60 mph at Rochelle, near Dewey, in the Badlands, Cactus Flats, Cottonwood, Phillip, and Belvidere.
