SIOUX FALLS, SD -
We have a very cold day on the way for KELOLAND with wind chill advisories in effect for much of the east until noon. Pockets of blowing snow are still creating problems in northeastern SD and eastward into western MN. Winds will stay stronger today in MN, but wind speeds will fall to the west of Sioux Falls and cold air continues to push south.
A cold night tonight is forecast with lows in the teens below zero in Aberdeen, with around -7 in Sioux Falls. This cold air will remain in place ahead of the next storm system.
A large area of KELOLAND is under a winter storm watch for Thursday. Basically, areas southeast of a Martin, Pierre, Sisseton line are included. This watch means there is the potential for heavy snow of 6” or more. We will need to watch the latest data, but snow appears likely tomorrow afternoon and evening in the west. This will spread East River Wednesday night through Thursday morning.
The majority of the heavy snow will occur during daylight hours on Thursday. Strong east winds will continue at 15-25 mph, so some blowing snow will occur, especially in the southeastern areas of KELOLAND.
Once this system begins to end on Friday, another storm will develop later in the weekend. We could be looking at more accumulating snow on Sunday into Monday, with the best chances of snow in the southeast. Stay tuned for more on this system in the coming days.
