It is a cold day in eastern South Dakota, with warmer air just west of the James River. Unfortunately, the ribbon of warm air will be followed by another front packing strong NW winds later tonight through tomorrow.
On the leading edge of the warm air is a band of very light snow, in northern South Dakota. As it crosses the area overnight, under 1” of light snow will fall. The problem is that we’ll have more wind-driven snowflakes tonight and tomorrow. It should not be as severe as our recent blizzard (winds won’t be as strong), but there could certainly be travel problems in open areas, especially along both sides of I-29 to the east into SW Minnesota. (Rule of thumb: if you can see a wind turbine, you are in the area most likely to experience blowing snow problems late tonight and tomorrow.)
A Winter Weather Advisory is posted for eastern South Dakota and western Minnesota, starting at midnight tonight and running until 6 pm tomorrow. Aberdeen, Pierre and Mobridge are in a Wind Advisory.
For the entire region, we expect NW winds 25-35, with higher gusts, tonight and tomorrow. Temperature-wise, not so bad. In fact, temperatures tomorrow may even be warmer than today… around 30 in eastern South Dakota.
We’re really looking forward to Sunday: Upper 30s in eastern KELOLAND, and the 40s to 50s West River. Skies will be mostly sunny. And we’ll keep sunny skies for Martin Luther King Day (Monday) as well.
