How Snowpack Plays A Role In Temperature

SIOUX FALLS, SD -
While we haven't had any significant snow for the last couple of days, what we do have on the ground is still affecting our weather in a big way.
This winter season has many people thinking of the harsh, snowy winters of the late 1960s and early 1970s. They were similar to this winter and brought more than snow. They also brought plenty of long-lasting cold weather to the area.
That's because when we have several inches of snow on the ground, it becomes very difficult for the air near the surface to warm. While we have much warmer temperatures flowing several hundred feet above the ground, the snow creates a bubble of cold air near the surface. The only thing that can really break down that bubble is a strong south wind that mixes down the warmer air.
Unfortunately, it looks like the warmer air will be held at bay for the foreseeable future with more snow on the way for the weekend.
