Tonight will be a clear night with light westerly winds. Temperatures will cool to within a few degrees of zero again.
Wednesday will bring increasing clouds from the southwest and highs mostly in the teens. Western South Dakota will see snow move in Wednesday night. A Winter Storm Watch has been issued for southwest and south-central SD for late Wednesday through Thursday morning.
On Thursday, a band of snow will travel southeast from western KELOLAND to southeastern KELOLAND and out of the area Thursday night. Snowfall estimates still have the heaviest snowfall likely to be found in the southwest and western counties where snowfall amounts will range from two to six inches, with some locally higher amounts possible. The south-central counties will see about one to four inches and the southeast will see trace amounts to up to three inches. The northern counties will see trace amounts to one inch.
Friday looks quiet with partly cloudy skies and afternoon temperatures in the 20s to low 30s.
The weekend brings another chance for significant snowfall and strong, gusty winds. Low pressure will track to the south of KELOLAND and move northeast. Southeast KELOLAND may actually be warm enough to see an rain/snow mix early Saturday before it switches over to snow. Leftover snow is possible Sunday morning. Highs this weekend will be in the 20s to lower 30s.
