A warmer air mass will move into the Midwest tonight so we could see tonight’s low temperatures this evening with increasing temperatures overnight. Skies will remain clear to mostly clear with calming winds.
Tomorrow will be sharply warmer across KELOLAND. Skies will be mostly sunny with highs in the upper 30s to low 40s East River with 50s and 60s found in central and west SD. East KELOLAND will have a calm, west or northwest breeze at 5-15 mph with a little stronger winds in western South Dakota.
Monday will have a strong northerly wind and slightly cooler afternoon highs, though temperatures will still be above-normal for mid-December. We’re looking for highs in the upper 30s to mid-40s. A snow system will move through the Midwest Sunday night lasting into Monday morning but the bulk of the snow is expected to hit northern Minnesota and Wisconsin. That being said, KELOLAND could see some wraparound light snow or even light rain.
Skies will be partly cloudy on Tuesday as slightly cooler air continues to ooze into east KELOLAND. We expect highs to be in the low to mid-30s East River with 40s to the low 50s for central and west SD. Wednesday is looking similar but a few less 30s and more highs in the 40s to near 50 degrees.
Skies should be partly cloudy on Thursday and Friday, with highs still in the mid-30s to low 40s East River, while central and west SD reach the 40s and 50s. Next weekend is showing some early signs of another area of low pressure that could bring KELOLAND much cooler air with some rain and snow.
