Light rain will travel southeast tonight as overnight temperatures cool to below average lows, in the 30s to lower 40s.
Sunday looks mostly cloudy as well, with lingering light rain coming to an end in the afternoon. Colder air will slide into the region so highs will mostly be in the 40s. Those high temperatures may set records for coldest afternoon highs. Rapid City and the Black Hills may even see a mix of rain and snow in the morning.
Monday morning will be chilly, with lows in the 30s. Then we’ll see some showers move into western and southern South Dakota, with below-normal highs in the 30s, in the west, to 40s and 50s in central and east KELOLAND. Again, folks around the Black Hills may get a mix of rain and snow with accumulating snow likely Monday night.
Another broad area of moderate to heavy rain is expected on Monday night into Wednesday morning, though the risk for severe weather looks rather low. But we could get another inch or two of rain out of this system. Highs will still be below normal, reaching the 50s to 60s, little cooler in the west.
Temperatures look to remain mostly below normal the rest of the week, though we will probably get into the 60s to low 70s by next weekend.
