Enjoy the mild weather ahead because big changes are just around the corner.
With partly cloudy skies, highs will reach into the lower 50s in Rapid City, mid-40s in Pierre and upper 30s in both Aberdeen and Sioux Falls. This trend will come to end Wednesday night as cold front slides south in KELOLAND and a much colder forecast begins.
Highs Thursday will hit early in the day, with temperatures holding steady or falling in the afternoon. Areas of light snow will develop as well with some accumulations expected. A general one to three inches of snowfall is expected, with the heaviest totals likely in the Black Hills region with over three inches. A winter weather advisory has been posted for Rapid City on Thursday. This will likely be the biggest system to affect KELOLAND before Christmas.
We expect much colder weather on Friday, with slightly warmer forecast on Saturday. Highs will be below normal through the weekend, but a warmer trend should arrive by Christmas Eve with highs returning to the 30s and 40s.
