Last night’s snowfall left a general 2-5” swath of snow across central and SE KELOLAND (Sioux Falls 2.9”). Today we’ve had another band of snow work its way across western and central South Dakota, with more snow falling in Rapid City and Pierre. Temperatures have been about twenty degrees colder than normal, with most areas in the single digits. Northerly winds have been gentle, under 15 mph.
An area of light snowfall will make its way across south central and SE South Dakota this evening, and then exit to the east overnight. Amounts should be light, under an inch. Thanks to the fresh snow cover and clearing skies, low temperatures should drop below zero across the entire region.
After a subzero start to Saturday, skies will be mostly sunny but not much warmer. Highs will only be in the low teens, perhaps a little warmer in NE South Dakota where there is less snow on the ground. Winds will be light, under 15 mph.
Sunday will be sunny and dry and a little warmer, in the mid teens to mid 20s, with a northwest breeze.
It looks like colder than normal temperatures will linger into Monday and Tuesday of next week, with highs in the teens and 20s. We’re eyeing a system developing in Colorado that may impact western and south central South Dakota. If there is a change in the wind pattern, we may have to extend the snowfall chances toward Sioux Falls.
Wednesday, Valentine’s Day, is looking warm. Highs will reach the 30s East River, to the low 40s in the west. We’ve had to back off the warmth for Thursday and Friday of next week. We’ve also added a little light snow on Thursday, so highs will mainly be in the 20s East River, to the low 30s in Rapid City.
