SIOUX FALLS, SD -
As is typical in South Dakota, this winter has been anything but dull. We've had a couple of blizzards, some ice, and even a rain storm.
But as we settle into some of the coldest weeks of the year, our temperatures will be on a rollercoaster as several weak systems pull through.
This pattern will usher in a number of alberta clipper-type systems. These fast moving systems have two phases. First, they pull in some warmer air along a warm front so we'll get a quick warm up. But as the system passes through the area, it drags down much colder air on the backside with a cold front.
Going into next week, we'll see two or three of these systems pass through. Temperatures will be warmer one day and back in the deep freeze the next. The good news is that our chances for snow are slight and any that does fall should be light.
