There will likely be some scattered sprinkles and rain showers tonight as a cold front moves through the area, causing north central SD to have the highest chances for the rain. The cold front will also cause winds to pick up overnight into Tuesday morning, with gusts of 25-35 mph for most areas while central SD will see the strongest gusts of 35-45 mph. Temperatures will be cooler tomorrow, and will continue to cool into the remainder of the week.
Snow will be returning through the rest of the week starting late Tuesday night into Wednesday morning with another round on late Wednesday into Thursday. The heaviest snowfall is expected over central SD Wednesday and then over northeastern SD Thursday, with the highest confidence in snow totals over central SD who could see 2-4 inches. Winds could gust up to 25-35 mph during the afternoon and cause some localized areas of blowing and drifting snow, which could reduce visibilities at times.
