Areas of fog have developed across western SD this morning with a cold front dropping to the south. Temperatures will be cold in the Aberdeen area with highs struggling to the hit 20. Sioux Falls will spend much of the afternoon in the upper 20s with a light north wind.
Overnight weather will be quiet with lows in the single digits in the northeast with teens in the south and west. This will lead into a warmer day tomorrow as winds pick up from the southeast during the day ahead of the next storm system. Highs will range from the upper 20s in the north to the lower 40s near the Nebraska border.
Our attention will then turn to the storm system for Friday night and Saturday. This system looks warm, so rain is going to the dominate form of precipitation. North of Sioux Falls and areas west could see areas of snow and freezing rain. The ice potential is greatest just north of Sioux Falls where the snow cover is deeper. We’ll watch the data and keep a close eye on how much ice could develop. The trend is for the system to be warmer with each computer model run, so if this trend continues, the ice threat would diminish. Here's a look at 3 models and how they compare.
Otherwise, moisture will be welcome for the drought areas with locally over .50” of rain in parts of southeastern SD and NW IA.
Weather trends are looking dry Saturday night into early next week with seasonal temperatures.
