The forecast looks very cold again Thursday with wind chill advisories and warnings in effect for much of eastern KELOLAND until noon Thursday. Look for slowly rising temperatures through the day with mostly sunny skies. Highs will range from near 30 in Rapid City to around 6 in both Sioux Falls and Aberdeen late in the day.
The next headline will be a blizzard watch starting Thursday evening for parts of NE SD and SW MN. We expect very strong winds to develop in these areas tonight and widespread blowing snow will be likely. The watch includes Sisseton, Milbank, Marshall, and Worthington.
Temperatures will be much warmer Friday in KELOLAND, with highs near 40 in Sioux Falls and upper 30s in Aberdeen. Some light mixed precipitation is also expected, so we’ll need to watch the road conditions for that, mainly east of the James River Valley. It will stay windy in most areas Friday with winds of 20-40 mph from the northwest. By the way, the high Friday will be near 55 in Rapid City.
Saturday still looks mild West River, but East River areas will be colder again behind another cold front. We do expect another warm front to develop Saturday night and this will trigger a band of accumulating snow Saturday night into Sunday, mainly just north of Sioux Falls.
The amounts of snow look heavier in NE SD too. Even an inch or two would be enough to create another blizzard late Sunday into early Monday as strong north winds redevelop once again. Stay tuned for updates on this forecast. I'll have more on this system on my facebook page, KELO Brian Karstens.
Much colder weather will linger here in KELOLAND on Monday and Tuesday once again as the winter pattern continues. Stay tuned!
