Widespread rain in western South Dakota will slowly move east through tonight and tomorrow. In the meantime, isolated showers and thundershowers have developed in north central South Dakota and east of the James River Valley. These are widely scattered and will slowly go away after sunset. The more persistent rain in western South Dakota will move into central South Dakota tonight and eventually into eastern KELOLAND for Saturday.
Skies will be mainly cloudy on Saturday with on and off showers likely.
Winds will also be strong from the north and northwest at twenty to thirty-five miles per hour with occasional stronger gusts. Highs will be well below average with widespread fifties likely. In summary, it will be a cold, blustery fall day for the first day of June.
Winds will die down and clouds will decrease on Sunday. This will allow for warmer temperatures with highs returning to the sixties to near seventy. The warm and dry weather will last into Monday, but another round of showers and storms will be likely on Tuesday with lingering rain on Wednesday.
