Mostly sunny skies will continue through the afternoon and evening with temperatures remaining in the upper seventies to lower eighties. Winds will also remain light from the south at five to ten miles per hour.
The overnight will be mostly quiet with a slight chance for isolated showers and thundershowers in southeast KELOLAND by daybreak. Lows will fall to the sixties with the thick clouds in southeast South Dakota to the fifties in northeast, central, and western South Dakota.
Isolated showers and thundershowers will be possible Wednesday morning east of Interstate 29. Anything that develops will move northeast with many locations in KELOLAND mostly sunny by the afternoon. Wednesday afternoon will feel like summer with highs returning to the middle eighties in eastern South Dakota to near ninety in central and western South Dakota. The humidity will also be a little higher as dew points return to the sixties.
A cold front will move through the upper plains Wednesday night to spark isolated showers and storms. Even though the humidity will be a little higher at the surface, it will be lacking in the higher layers of the atmosphere. It is for that reason that the rain will be widespread.
Thursday will be breezy and cooler with highs in the low to middle seventies. The brunt of the cool air will move in on Friday with morning lows in the forties and afternoon highs in the sixties. Temperatures will slowly warm for the weekend with highs returning to the low to middle seventies.
