Today we saw a massive contrast of temperatures across KELOLAND. Rapid City made it into the 50s and Aberdeen still struggles to break 15°! Even with a warm front starting to stall in central South Dakota, we’ve kept clear skies in most locations.
With light winds and clear skies tonight, we’ll drop off quickly after sunset. Lows will be in the single digits along I-90 with below-zero readings along the North Dakota border. Watch out for patchy morning fog along rivers and in eastern South Dakota.
Rapid City will be colder tomorrow but should still be the warmest metro area. Otherwise, expect a similar day for most other locations. The main difference will be wind direction, as a light north breeze takes over.
A clipper system will track through North Dakota this weekend. That could lead to lighter snows along the border. This looks like it will eventually dive into our NE by Monday. Light snow caused by very cold air could come to Aberdeen on Sunday, early in the day.
On Christmas, another storm arrives in the SW parts of South Dakota. Most computer models agree that Rapid City should get some decent snow and our chances are highest there. Sioux Falls also has a slight chance. There will also be a large-scale system well east of here that could impact flights from Chicago to the Tennessee Valley.
Sharply colder air moves in midweek and we’re also watching another snow event for next Friday throughout KELOLAND!
