It has been partly to mostly cloudy across KELOLAND today, with temperatures cooling back to normal for late January. We’ve even had a few light flurries or snow showers. Fortunately the breeze has been lighter than recent days.
Tonight we’ll have thickening clouds as the winter weather system arrives from the southwest. Rapid City could have some of the light snow overnight as it comes in. Lows will e in the teens to around 20 with a very light south breeze.
Tomorrow we expect widespread light to moderate snow under cloudy skies. Forecast models continue to suggest a widespread 2-4” of snow. A SE wind 10-20 mph may blow around some of that snow, especially along the Buffalo Ridge (areas near the wind turbines) where winds and snowfall intensity will a little higher. Temperatures will be in the 20s in Eastern KELOLAND and the low 30s in the west.
