An afternoon thunderstorm brought heavy rain to an area south of Rosebud this afternoon. A tornado was spotted across the border in Nebraska (west of Valentine). Latest computer model projections bring thunderstorms to Sioux Falls and SE South Dakota after dark.
The rain and thunderstorms coming through the area are being caused by a cold front. Behind the front, temperatures are only in the 50s in western South Dakota, and 60s in the northeast part of the state. Sioux Falls and the southeast are in the 80s.
The front will being a continued period of rain into the day on Saturday. Temps will be cooler across the region as well, with highs only in the 60s to low 70s. Sunday will also be cool, but skies will be mostly sunny.
We expect temperatures to return to late spring normal next week. That means lots of days in the 70s.
