Blizzard Warnings are in effect for much of northeastern SD and western MN starting at 6am Sunday morning until midnight. Widespread blowing snow with visibilities below ¼ mile can be expected much of the day. High Wind Warnings have also been posted for much of KELOLAND including Sioux Falls for Sunday with NW winds up to 60mph.
Areas of snow will continue to move across eastern KELOLAND, mainly east of the James Valley associated with a warm front. Temperatures will rise overnight in many areas, reaching into the upper 30s in Sioux Falls after midnight. Aberdeen will also see temperatures rising into the 30s. The amounts of snow tonight will generally be 1-2” from Sioux Falls-North late tonight into the first half of Sunday.
The new snow will be blowing around in the developing wind Sunday. We expect the strong winds combined with areas of light snow will create hazardous travel, with the worst conditions north of Sioux Falls. Temperatures will be dropping through the afternoon with morning highs in the 30s in southern KELOLAND. Wind chills will be very cold by late in the day, dropping as low as -45 in parts of SW MN by Monday AM.
Monday looks very cold with subzero highs likely East River. The winds will also stay rather breezy for the first half of the day from the northwest.
Tuesday is looking a little better…slightly warmer and less wind. As the mercury warms into Wednesday, we expect areas of snow to develop once again late in the day. Thursday through Saturday could turn into a snowy period…something to watch in the days ahead.
