The Blizzard Warning now splits the Sioux Falls metro area. To the north of town, the snow line and amounts will change very quickly, the farther you head north and west. South of town and into Iowa, we still expect a good amount of rain. Isolated thunderstorms are even possible late tonight and into tomorrow morning. You can find the snowfall totals map plus winter weather alerts at the bottom of this screen. We’ll also have a crawl running at the bottom of KELO-TV with current conditions.
Sioux Falls to Yankton is the line for the rain/snow changeover and if the storm moves east at all, more snow will move into these areas. This is a very fluid storm system, which means snowfall totals are still subject to change.
Heavy snow will move in tomorrow morning in central South Dakota but lighter activity should begin later tonight. Winds will also strengthen tomorrow, mainly after the noon hour. Blizzard or ground blizzard conditions will be prevalent in much of central and northern KELOLAND. With that, expect plenty of travel issues as visibilities deteriorate.
Blowing snow will become a big factor tomorrow afternoon as upper-level support increases banding snow and blizzard conditions.
The weather northwest of Sioux Falls will be quite a bit worse but by late tomorrow night blowing snow will try to move into town. This means that even if you don’t get too much heavy snow at first, drifts could form at your doorstep. Many activities tomorrow and Monday have already been canceled but if you have travel plans, check local road conditions. You can do that for free at SafeTravelUSA.com.
Winds will still be very strong on Monday in eastern KELOLAND, causing more blowing snow.
After this all clears out we actually get some sunshine on Tuesday!
