Look for a warmer day in KELOLAND with highs in the 90s in western areas and near 85 in Sioux Falls. The warmer air will be accompanied by a few scattered showers and isolated t-storms in central and western South Dakota. Those scattered areas of rain may track east toward Mitchell, Gregory, and Yankton overnight. Sioux Falls will have a slim chance of rain toward tomorrow morning.
Otherwise, chances of rain will remain lower in Aberdeen and Watertown. We’ll keep a 20% chance of rain in forecast as a weak cold front moves across the region. Highs tomorrow will remain warmest in western KELOLAND in the upper 80s.
Hotter weather is likely by Friday and Saturday as the jet stream changes and allows the hotter weather to move back into KELOLAND. This spike in temperatures should decrease on Sunday and Monday as a trough of low pressure in the northern Rockies brings cooler weather and areas of rain to the northern plains. This is by far the most organized chance of rain in the 7-day forecast.
