Light snow continues to fall, with amounts generally around an inch. There has been a narrow band of heavier snow – roughly from around Salem, SD to Flandreau, to Pipestone, MN where three to four inches has been measured. There is a Winter Weather Advisory posted for that area (Moody County, SD plus SW Minnesota) until early evening.
Tonight we will have more light snow, but little in the way of accumulation. Skies will be cloudy, with a light NE breeze, and overnight lows in the single digits above- and below-zero.
Tomorrow will be cloudy as the next round of snowfall comes up from the southwest. Snow will start in western South Dakota and then move east during the afternoon and nighttime. Winds will increase from the west by Wednesday night along with the snow. Temperatures will be colder than normal, in the single digits to the low teens.
A Winter Weather Advisory is posted for most of KELOLAND tomorrow afternoon through Thursday. Amounts will be a little heavier from Highway 14 to the north than in the south. But as the northerly winds increase for Wednesday night and Thursday, areas of blowing snow (and possible travel problems in open areas) are expected.
With those strong winds, Thursday is going to be cold even as the snow tapers off. Lows will be a few degrees below zero, and afternoon highs will only be in the single digits above zero.
The center of the cold air mass will come through on Friday, so Friday morning will be especially cold, in the teens or even 20s below zero. Sunny, dry air will be slow to warm, so central and eastern KELOLAND will probably remain below zero all day.
Saturday will be mostly sunny and slightly warmer, in the single digits in the north to the teens to around 20 in the south. Sunday will be about the same temperature-wise, but a low pressure system moving through Nebraska will probably push some snow our way. It could be another couple-inch type event.
Another cold air mass will drop down out of Canada on Monday, so it will be sunny and cold. But as we’ve been saying, the long-term trend also continues to look cold, with much-below normal temperatures likely through – at least – President’s Day (February 18).
