South Dakota may be contending with some rough weather before the night is through. But then what will come for the beginning of the weekend? That’s the mystery, isn’t it?
At 652PM, MT, Rapid City was reporting a temperature of 75 degrees with clear skies. Strong thunderstorms were erupting on a well defined warm front, running from south of Sheridan Wyoming to north of Mobridge. There was a severe thunderstorm likely producing large hail north of Hulett, in the far northeast corner of Wyoming. A short wave trough pivoting through the northern High Plains will initially bring a surge of clear, if hot and sticky air through overnight into the early afternoon tomorrow.
A cold front arriving on the area at the back end of the same system has the potential to touch off a few thunderstorms in and around the Rapid City area tomorrow evening, but the greater threat will be in the center of the state. Heavy rain and thunderstorms will press east through the Dakotas, while the Black Hills and Rapid City get an infusion of cooler, dryer air Friday night, leading to a quite pleasant day on Saturday.
