We are looking at a sunny day today East River with a very light SE breeze and afternoon temperatures in the single digits. Western South Dakota will be warmer, but will also have a chance at some late day to early night snow. It appears snowfall amounts in western South Dakota will be fairly light.
Winds will change to a northwesterly direction as upper level energy will sweep across the area tomorrow. As the energy moves through, we’ll have a chance for some powdery snow, especially late in the day. Fortunately it will also be warmer with daytime highs in the mid-20s East River (near normal for this time of year) and near 40 in western South Dakota.
Next week is looking snow-free Monday through Friday. We will also have a lot of sunshine, mostly because we will have large amounts of cold, dry Canadian air incoming.
On Monday, brisk northerly winds will bring another blast of arctic air. Even though skies will be sunny on Monday, we’ll also have a tough time warming much above the zero mark during the afternoon.
Tuesday will be very cold in the morning, in the teens or even 20 degrees below zero. Tuesday afternoon we’ll have sunshine, with highs in the single digits.
Skies will be mostly sunny Wednesday and Thursday, and temperatures will be sharply warmer, in the mid-20s East River on Wednesday and the mid-30s on Thursday, which should be the warmest day of the week. Rapid City has a shot at 50 Thursday afternoon.
It also looks like temperatures will remain above normal Friday through the following weekend.
