Skies are cloudy, and light to moderate snowfall is already underway in much of the area. Snow has been heaviest in the central South Dakota. 3” has been reported so far in Roscoe. Snow will continue to be heaviest through this evening in the central South Dakota to the James River valley, where a Winter Weather Advisory is in effect for 2-5” snowfall. But there might be a period of some freezing drizzle mixed in with the snow. Fortunately winds have been less than 15 mph.
Tonight we’ll continue to see light snow (possibly mixed with light freezing drizzle) in central and eastern KELOLAND. Snowfall amounts will be around an inch or two. Thanks to the cloud cover and light SE breeze, lows will remain in the teens to low 20s ABOVE zero.
Tomorrow we will continue with the snowfall, along with fairly mild temperatures in the 20s. Another inch or two will be possible, but it might be mixed with light drizzle at times. There will be a gentle northwest breeze during the day, but winds will really pick up by Saturday night, when blowing snow issues may actually create ground blizzard conditions.
A Winter Storm Watch is posted for SW Minnesota and NW Iowa starting at midnight Saturday through Sunday afternoon. We aren’t expecting new snowfall during that period, but very strong NW winds gusting over 40 mph at times will pick up existing snow cover and blow it across area roads, creating ground blizzard conditions. Visibility could be impacted, especially in open areas.
Otherwise, skies on Sunday will be partly cloudy, and we’ll start to feel colder air move in with highs in the low to mid teens along with those strong NW winds.
Monday, Tuesday, and Wednesday of next week will be dominated by our next blast of Arctic air. Expect subzero mornings and single-digit to low teen afternoon highs – about twenty degrees colder than normal for the last few days of February. We may even squeeze out some light snow events, but the amounts will be minor (generally under an inch) due to a lack of moisture in the incoming cold air.
Temperatures will ease a little for the second half of the week. But… every night for the past three weeks I have put a similar graphic on TV stating this: Below or much-below normal temperatures are LIKELY through at least the first week of March – and probably through the following week as well.
