A fast moving band of snow has skipped through KELOLAND, with only minimal amounts (well under an inch). Very strong northwest winds have blown around snow that is already on the ground, creating some travel issues. A Winter Weather Advisory was posted due to blowing snow.
Tonight will be cold, with the northwest breeze creating significant wind chills – although wind speeds will decrease. With mostly clear skies, overnight lows will be below zero, and northeast South Dakota will be in the teens below zero.
Tomorrow will be partly cloudy East River and mostly cloudy West River. Winds will be light, but highs will only be in the single digits East to the low teens in the West. An area of light snow will develop in western and central South Dakota during the morning, and move into the James River valley during the afternoon. Sioux Falls could get some of that light snow by Friday night. At this time that snowfall amounts look under an inch, or an inch or two in the case of western South Dakota.
There will be a better chance of a “couple-inch” type of snowfall event for the weekend, which is also looking like it will be dominated by cloud cover. The snow does not look heavy, but it will be persistent – which is why we could see some low-end accumulations. Temperatures will remain below normal Saturday and Sunday, with highs both days in the teens.
Snow could linger into the morning hours of Monday (President’s Day), but then we’ll see the cloud cover leave us. We’ll have another pool of cold Arctic air drop down on us, so we’ll have subzero mornings on Monday, Tuesday, and Wednesday; and the afternoon highs will only be in the single digits to mid teens – although it also looks like we’ll enjoy a fair bit of sunshine.
It does look like temperatures will be a little warmer for the next half of next week – although they will still be colder than normal for the third week of February.
Every night for the past week and a half I have put a similar graphic on TV stating this: Below or much-below normal temperatures for the remainder of February – at least. We simply do not see any signs of a thaw – at least not in any data going out through the end of this month.
