Thunderstorms tracked across much of northern KELOLAND overnight. The heaviest rain and severe weather tracked west of Mobridge during the evening, with flash flooding south of Mobridge. Around 1.5” of rain fell in Aberdeen since midnight, with additional flash flood warnings posted just north of Ortonville. Morning storms also developed in SW MN and NW IA with additional pockets of severe weather and heavy rain from Spirit Lake to Windom.
In the wake of the scattered storms, warmer and more humid weather is likely today in much of southern KELOLAND. Sioux Falls will be in the upper 80s, with the heat index value between 90 and 95. There is a slight chance of thunderstorms in the late afternoon in the southeast, with a better chance of storms in the Black Hills by this evening.
Look for lows in the 60s tonight with more scattered t-storms, mainly West River. Look for more scattered storms tomorrow in western and central KELOLAND. Those areas of rain should become more numerous tomorrow night and Saturday across much of KELOLAND. Highs should still be in the 80s in the southeast, but cooler 70s are likely in the north and west. We’ll maintain more chances of thunderstorms Sunday as a slow-moving front moves across KELOLAND.
Look for cooler weather early next week with more rain chances by Monday night into Tuesday.
