Sioux Falls, SD
A very busy week of weather is ahead in KELOLAND. We are starting with scattered showers and t-storms in eastern KELOLAND. Some of the storms have heavy rain with some small hail. Most of the rain will continue to track into NW IA and western MN during the morning, with warmer temperatures expected this afternoon west of Sioux Falls. Highs will be near 90 in both Pierre and Rapid City, with Aberdeen not far behind in the mid to upper 80s.
Tonight looks quiet with partly cloudy skies and lows in the upper 50s to lower 60s. The forecast will change tomorrow as a strong cold front moves in from the north. We expect showers and t-storms to develop during the day from west to east. Storms will strongest late in the day in the southeast, with severe weather possible in NW IA. It also looks like heavy rain will be possible in much of eastern KELOLAND, with locally 1+” possible. The wind will be shifting to the north during the day in the Rapid City, a trend that will spread east tomorrow night into Wednesday.
Sharply colder weather is expected Wednesday with scattered showers and blustery north winds. Highs will struggle into the 50s, and the “feels-like” temperatures will be even colder. The colder weather will continue for the rest of the work week.
We are watching the potential for snow in the northern Black Hills Wednesday night into Thursday. There is also the potential for frost later this week in eastern KELOLAND. This will depend on how much clearing we see by either Friday or Saturday morning. Stay tuned for details on this through the week.
