Scattered showers are currently moving through central South Dakota and extreme southeast South Dakota this afternoon. These showers are moving northeast and do not pose a severe weather threat. We’ll watch for developing storms east of the James River Valley for the potential to become severe during the late afternoon and early evening. The main threat for severe weather is large hail.
Scattered showers and storms will move through eastern KELOLAND this evening and tonight. Periods of heavy rain will be possible with some of the stronger storms this evening and tonight. Lows will fall to the sixties to near seventy, so expect a mild and muggy overnight.
Thursday will be partly cloudy and warm. Highs will make the middle to upper eighties with light southeast winds.
Cooler air will move into the upper plains starting on Friday. This will help spark showers and storms in northern, central, and western South Dakota. The rain will move through KELOLAND Friday night into Saturday. The clouds, rain, and northerly winds will help drop temperatures to the seventies in western, central, and eastern South Dakota. Temps will be in the lower eighties in southeast South Dakota, but they will fall to the seventies on Sunday. Western South Dakota will have some areas in the middle to upper sixties on Sunday as skies will be mostly cloudy.
The cool air will last into early next week with highs in the low and middle seventies Monday through Wednesday.
