Clouds in central South Dakota will slowly move east this evening and tonight. Lows will eventually fall to the teens and twenties for much of KELOLAND. Western South Dakota will have isolated light rain and light snow during the evening and into early tonight. Actual water amounts from the precip will stay at less than a tenth of an inch.
Saturday will start the slow warming trend. Highs in eastern KELOLAND will hit the lower thirties while widespread forties are likely in central South Dakota. Rapid City will warm to sixty. The warmth will last into Sunday, but clouds will also be on the increase. Highs on Sunday will be in the upper thirties in eastern KELOLAND to the fifties in western South Dakota.
Snow will start Sunday night in north central and northeast South Dakota. It will dive south Monday morning and afternoon. This looks to be a fast moving system; so much of the snow will be done Monday night. Snow amounts of three to six inches or more look likely, but exactly where that lines up is yet to be seen. High temperatures will fall below average for Monday and Tuesday, but above average highs will return by Wednesday.
