The first wave of light snow has exited South Dakota into Minnesota, with reports of an inch or two coming in. Sioux Falls totaled 6/10 of an inch this morning, Aberdeen 2.4".
Tonight, the next wave comes through, with up to an inch of additional light snow. Otherwise it will be another cold one. Forecasting -3 for Sioux Falls and -12 for Aberdeen. Bundle up if you're going to the fireworks.
Tomorrow, the New Year comes in on the chilly side. Single digit highs East River, with light NE breeze. Rapid City will be much warmer, at 26.
Thursday will be very cold in the morning. Teens below zero East River. Daytime highs, under Partly Cloudy skies, will be only a few degrees either side of zero East River, while Rapid City will again be in the 20s.
Then temps will moderate for the weekend. Breezy 20s East and 30s-40s West for Friday. Saturday will be just as warm, with another chance of light snow. But don't celebrate a heat wave just yet. Monday will be extremely cold, perhaps the coldest air yet this season. Most of KELOLAND will fail to get above zero.
One other note: it appears Lead will be just short of 50 inches of snow for the year. The state climatologist will check the numbers on Thursday, but it is likely to be a new yearly snowfall record, anyway.
