By late Sunday clouds will really thicken up in advance of snow showers that will move in Sunday night into Monday. The snow will be heaviest across the northern Hills where a Winter Storm Watch has been posted and 3-6+ inches of snow will likely fall. Elsewhere, we are generally looking at 1-4 inches of snow by the time things wrap up on Monday night. The system will work from west to east with the heaviest snow falling during the overnight hours out west, the morning hours in central SD and through the afternoon and evening in the east. We will have a challenge in SE KELOLAND where temperatures may lead us into some freezing drizzle. It is something to watch closely as the event approaches, the best threat for that would be earlier Monday with a changeover to snow by afternoon. Lesser amounts of snow are expected in the SE with most folks picking up about an inch; 1-3 inches will be likely farther north. We will also have blowing snow with this system as winds pick up during the snow event. Expect tricky travel through the day Monday across the state.
Tuesday will bring a quieter day and the weather should stay quiet before another system looks possible for the end of the week and the weekend.
It is looking like a quiet and mild night with another nice day coming on Sunday. Clouds will again be prevalent on Sunday with filtered sunshine at times. We should be able to warm into the 30s for the central and west with 40s likely in the southeast.
