More rain fell in KELOLAND last night, some of it heavy once again south of Sioux Falls. Evening storms produced a couple of weak tornadoes north of Yankton near Mayfield. The low pressure system responsible for the rain is still slowly moving east this morning and chances of scattered rain will continue in southeastern KELOLAND. More isolated rain will be possible from Aberdeen to Rapid City. Highs today will be in the mid to upper 70s in Sioux Falls with clouds and scattered rain, with lower to middle 80s in the west.
Evening showers and t-storms east of I-29 will decrease overnight with lows in the upper 50s to lower 60s. Tomorrow looks drier with partly cloudy skies. Scattered t-storms are still possible in western KELOLAND, but our East River areas will stay mostly dry until late Saturday night as a warm front develops to the west and triggers scattered t-storms.
Thunderstorms are likely on Sunday, with a warm front triggering some scattered rain in the morning in eastern KELOLAND. The bigger focus of t-storms will be Sunday afternoon as a cold front moves into eastern SD. Severe weather will be possible along and ahead of this front, so stay tuned to the latest forecasts through the weekend.
Labor Day should be cooler as storms move to the east. However, more scattered t-storms are possible by Tuesday.
