It's a warm night, then pick a temperature, any temperature, fo r Sunday. South Dakota stays hot, but cooler air pushes into Wyoming Sunday with a few thunderstorms. Isolated evening storms are possible around the Hills Sunday and Monday.
Thunderstorms are more likely into Tuesday along with cooler temps again. If the storms move out on their current track, the first three days of July look dry - Good news for Mt. Rushmore fireworks Friday!. But a few afternoon or evening storms could come back on the 4th. We'll keep tracking the progress of the storms!
