Scattered showers and storms will move through western South Dakota for the rest of the afternoon and evening. Some of these storms will become severe after 5:00. Elsewhere, partly cloudy skies will persist for a lot of us through the evening. Other scattered storms will develop in south central South Dakota toward sunset. If these develop, they will travel northeast into eastern and northeast South Dakota (from Brookings to Sisseton) by midnight. Once these pass through, many locations will remain dry during the overnight. Tonight’s lows will stay mild with temperatures falling to the sixties and fifties.
Saturday will feel like summer as the moisture (dew point) increases throughout the day. Highs will make the eighties with some areas pushing ninety in southeast South Dakota and northwest Iowa. It will also be a little breezy with southeast winds of fifteen to twenty-five miles per hour. As low pressure moves into central South Dakota a warm front will drape into northeast KELOLAND near Aberdeen and Sisseton. The warm front will be the focal point for severe weather early in the afternoon (around 4:00). As low pressure moves into eastern KELOLAND during the evening, storms will begin to fire along a trailing cold front.
Storms have a chance to become severe as much of KELOLAND is under a slight risk for severe weather as issued by the Storm Prediction Center. Not only will severe weather be a possibility, but heavy rain will also be likely (Saturday night). Some storms will be able to produce one to two inches of rain.
Much of KELOLAND will be behind the system on Sunday, but scattered rain will still be likely. Highs on Sunday will range from the upper seventies in southeast South Dakota to the sixties elsewhere. The rain chances will continue into early next week as temperatures will be well below average with highs in the sixties.
