Eastern KELOLAND will be socked in the clouds through the evening and tonight while clouds will continue to decrease in western and central South Dakota. Isolated showers will be possible in northeast KELOLAND tonight, but rain amounts will generally stay less than a tenth of an inch. Lows will fall to the thirties tonight.
The clearing skies will move into eastern KELOLAND late tonight and into Tuesday. Along with the increasing sunshine, northwest winds will be increasing to give way to a breezy afternoon. Highs will be warmer with afternoon temperatures warming to the fifties. Rapid City might be able to squeeze into the low sixties.
The warmth and dry skies will last for the rest of the week, and then our attention will focus on a pattern change for the weekend. Low pressure will slide through the upper plains on Saturday to eventually allow for developing rain and snow. Eastern KELOLAND will be very warm with some areas in the sixties, while western South Dakota will be much cooler with highs in the thirties. Western and north central South Dakota have the best chance for snow on Saturday and Saturday night. Much of eastern KELOLAND will stay dry with only a slight chance for rain. Once the system leaves, much colder air will pour into eastern South Dakota on Sunday. The temperature difference in the east will be about twenty to thirty degrees going from Saturday to Sunday.
