One more frigid night is expected tonight, with wind chills in the 20s to 30s below zero. A Cold Weather Advisory remains in effect. However, warm air will move back into the area Tuesday, and highs are expected to be in the 20s and 30s above zero! Blustery conditions will return Tuesday night as a clipper moves through, bringing snow and gusty winds. Thursday will be dry, but some light snow will be possible again Friday into the weekend, mainly in the Black Hills. Breezy to windy conditions are expected through the week.
A clipper system will bring some snow to the area Tuesday night into Wednesday. With gusty northwest winds, upslope snow is expected, so the northern Black Hills will receive the most snow. Minimal snow amounts are expected across the SD plains, and some light accumulations will be possible over northeastern WY. The northern Black Hills has the best chance (over 70%) of receiving more than 6 inches of snow.
