Ice built up overnight in the northeast, leaving more than a quarter inch of accumulation for some. With a lot of activities going on this weekend many are worried about travel.
Since there are so many Warnings and Advisories out for our area, you can find the list (along with the snow map) at the bottom of this report.
This morning we’re watching the north band of moisture and energy push into south-central South Dakota. Areas along I-90 and near Winner saw quick ice accumulation along with reduced visibility. Fog has been an issue so far across much of our region, leading into the storm.
Most of the state is cool enough for snow or at least freezing rain but Sioux Falls and the southeast should remain as rain until this evening.
Strong and cold north winds will soon push in on the back edge of this. That area in between should see a band of heavier snow developing through late this morning. The exact location is very difficult to pin down because these March storms shift on a dime. Because of the hybrid parts of this storm, we’ll see some convective snow which drops quickly.
Once the north winds cool portions of East River down enough, the storm will be pushing out to the east. That means much of NW South Dakota won’t see much, if any, moisture.
The change-over to snow will happen for our southeastern counties this evening and that should help form a second band of heavier snow. Most of that should be in northeastern Nebraska and northwest Iowa but some could clip the bottom of South Dakota. Even areas like Bon Homme and Turner Counties could see some snow piling up. We didn’t tweak the snowfall forecast map too much but right along the Nebraska border it will be interesting. We should see snow tonight in Sioux Falls but most of the moisture will be used as rain.
Water should puddle or pool in most spots as the ground is still frozen. That’s another thing to watch our for, since this should eventually glaze over.
A lot of us will even see sunshine tomorrow, even as colder temperatures move in. There will be a slow but steady warming trend this week. There is also a slight chance of rain or snow Tuesday into Wednesday, depending on your location.
