Sioux Falls, SD
Showers and t-storms have rolled across parts of KELOLAND again overnight. Winds to 85mph were reported south of Mission in south-central SD late last evening. The rain has been diminishing farther east, where the bigger storm threat will wait until this afternoon and evening.
We have a good chance of storms in eastern KELOLAND along and east of an Aberdeen-Winner line, mainly after 3pm. The storms are most likely to develop in northeastern KELOLAND, then will back build into northern Nebraska. The initial storms will likely be supercells, with large hail and damaging winds the main threats. However, an isolated tornado can’t be ruled out. The storms will advance east toward I-29 between 6pm and 9pm.
The storms will move east into MN through midnight, with more redevelopment of scattered showers and t-storms in southeastern KELOLAND after midnight behind the cold front.
Saturday looks cooler with breezy winds in the forecast and highs in the mid 70s in the north and mid 80s in the south. There could be a few cells on radar in SW MN during the afternoon, so don’t be surprised if that happens. The temperature trend looks warmer again by early next week with 90s again in Pierre and Rapid City by Monday. We do have chances of rain again Tuesday night into Wednesday, but this system doesn’t look organized at this time.
Again, stay tuned to the forecast later today for the latest watches and warnings in KELOLAND.
