The blizzard continues, mainly along and east of the James River Valley. Snowfall amounts have been moderate: Rapid City recorded about five inches, but Sioux Falls and most of eastern KELOLAND has been in the 2-4” range. Persistent NW winds have been gusting over 40 mph along an east of the James, where “no travel” is advised on many highways and rural sections of the interstates.
A Blizzard Warning continues east of the James River until midnight. The Winter Weather Advisory continues until 6 pm west of the James. Although winds will diminish overnight, a Wind Chill Warning remains in effect in the northern half of KELOLAND through tomorrow morning, and a Wind Chill Advisory is posted for the southern half.
Tonight the winds will diminish from west to east, decreasing the blowing snow threat. Clouds will also be breaking up. Temperatures will be very cold in the morning, in the teens or even the 20s below zero.
Tomorrow sunny skies will be unable to warm us very much – although winds will be much lighter than today. Northeast SD will probably remain below zero all day. Sioux Falls and the southern part of the area will struggle to reach the single digits. Rapid City and the southwest will be the only exception, getting into the teens.
Saturday will be partly cloudy and not as cold, in the single digits in the north to the teens to low 20s in the south. Sunday will be a little cooler, but a low pressure system moving through Nebraska will probably push some light snow our way.
There is another shot of snow coming our way late Monday into Tuesday, and it looks like another “few-inch” type event. Temperatures will remain below-normal. The center of the cold air mass will pass on Wednesday, which will be sunny and dry with highs dropping back to the single digits to the teens. Thursday (Valentine’s Day) will start dry, but we’ll have another shot at snow Thursday night into Friday.
As we have been saying, the long-term trend also continues to look cold, with much-below normal temperatures likely through President’s Day (February 18) and beyond. There is no sign of temperatures approaching normal for at least two weeks.
