Blizzard Warnings will continue through the evening in extreme northeast South Dakota. Winds of twenty to forty miles per hour are creating whiteout conditions at times, but the winds will decrease slightly later this evening leading to improved visibilities. Temperatures will fall below zero in eastern KELOLAND tonight with some teens below possible in northeast South Dakota. Central and western KELOLAND will fall to the single digits (above zero).
Tuesday will be the coldest day this week with highs in the single digits and teens covering central and eastern South Dakota to the twenties in the west. Winds will not be as strong on Tuesday, but eastern KELOLAND will still have northwest winds of ten to twenty miles per hour.
A storm system will come out of the southwest United States on Wednesday, giving central and western South Dakota a chance at snow. The snow will eventually move into eastern KELOLAND on Thursday. Models have backed off on how much moisture will get wrapped up in this system. What started out as three quarters to over an inch of liquid, has now backed off to almost half that amount (depending on the model). As of now, the best chance for accumulating snow will be for the southern half of the area.
Temperatures do not get bitterly cold behind this system, but another round of snow will be possible on Sunday and/or Monday.
