Storm Update (6:17pm Monday)...

Right now we're watching as a cold front moving in from the North and a lingering batch of moisture and messiness are colliding over the Sioux Falls area. That will result in some of the heavier bands of snow over extreme eastern/southeastern South Dakota and the rest of the region into southern Minnesota and northwest Iowa. In a lot of these areas 3" with locally heavier areas are not out of the question. Make sure to dial 511 or go to SafeTravelUSA.com/SD/ to check road conditions if you're doing any traveling.

This is our latest radar image from about 6:17pm Monday night:

If you look at those green patches you can see some heavier precipitation showing up. Unfortunately we don't have any true observations from that area, but there is a chance that is heavier snow and we can see it getting wrapped into the eastern South Dakota area and trending east toward NW Iowa. That's what we'll need to watch. Between now and our 10pm show is when we should expect the bulk of our snow to fall in the Sioux Falls area.That image above is from what's known as the RUC model, or the Rapid Update Cycle. It's not quite as accurate, but the computers run through it once every hour. What it is showing us future precipitation and that the computer models are starting to agree with my assessments above - so we'll see if it ends up that way by the end when we start listing snowfall totals. We'll update you on here as necessary - and drive safely!
