There really isn’t much to say about today. Other than that snowfall amounts will be limited (only an inch or two) – it will be about as ugly a winter day as can be.
Blizzard conditions are already leading to whiteout conditions in the northeast corner of South Dakota. Day County has requested no travel today.
Northwest winds will be in the 30-55 mile per hour range in eastern South Dakota and SW Minnesota today. That will blow around any loose snow, and visibilities will be very limited in open areas. Wind gusts over 60 mph are possible in western South Dakota.
A Blizzard Warning is in effect for NE South Dakota and SW Minnesota until midnight. Sioux Falls and the rest of South Dakota is under a High Wind Warning.
Blizzard conditions will wane tonight, but cold air will then sink in. Dangerous wind chills will continue through noon tomorrow, but the air will be just plain cold – subzero.
It is likely that eastern South Dakota will remain below zero despite sunshine all day tomorrow and tomorrow night. We expect many of us will have subzero temperatures for a prolonged period – more than 36 hours.
Tuesday will be another sunny day, with temperatures creeping a few degrees above zero (at best). The mercury should rise overnight Tuesday night, with Wednesday sharply warmer (near 30) before another front cools us back down on Thursday.
Bottom line – below normal temperatures through next weekend.
