We're into the Fall roller-coaster ride of temperatures as we take wild swings from the 30s and 40s at night to being in the 80s a day or two later. 
It was frosty in some areas this morning as readings dipped into the 30s at several locations across western South Dakota. It'll warm into the 70s this afternoon.
A storm system will develop over western Nebraska tomorrow. The weather will be warm and pleasant tomorrow with most of us seeing mostly sunny skies and highs in the low to mid 80s. The clouds will thicken on Sunday as showers and thunderstorms develop over Wyoming and eastern Montana. Those showers will spread across western South Dakota late Sunday afternoon and night.
Labor Day will be a very windy day (gusting to 45mph) with morning showers -- and maybe an afternoon sprinkle.
