Scattered t-storms continue to develop across KELOLAND on this Friday. Heavy rain is the main threat, with a flash flood watch in effect for Rapid City, Pierre, Aberdeen, and Watertown. Keep a close eye on the radar trends today as the storms develop. Highs will be mainly in the lower to middle 80s.
The main cold front will slowly move east tonight, bringing the highest chances of storms with it. Again, heavy rain will be a threat overnight. Look for lows mainly in the mid 60s, with upper 50s in Rapid City.
Showers and t-storms will continue to move east Saturday morning, so chances of rain will remain high in Sioux Falls. Scattered rain is possible West River again later in the day, but most of the severe weather threat should shift east of KELOLAND Saturday afternoon.
That scenario changes on Sunday. The exact placement of the surface boundary will help determine the highest risk areas for severe weather, but the latest data suggests much of southeastern KELOLAND will be prone to severe weather Sunday afternoon and evening. Large hail, damaging winds, heavy rain, and tornadoes will all be possible given the particularly strong ingredients clashing together at that time. We encourage you to stay alert to the latest forecasts through the weekend.
Early next week look quieter with slightly cooler weather. A warmer trend should arrive for Independence Day weekend.
