Cold Night

The coldest night of the season is on its way so if you dont have your heavy winter jackets out yet, you probably want to dust them off tonight. The center of high pressure in southern Canada is expected to make its way south today and that will clear out most of the clouds and calm the winds down. Now, because cold air is more dense then warm air, the cold air sinks to the surface and thats why it can get so cold. Here are some numbers that a couple of the models are saying for overnight lows.

All you have to do is look at those numbers and you will realize how difficult of a forecast the lows are tonight with the model numbers 5-10 degrees off from one another. I am going to lean toward the warmer temps (relatively speaking) just because there is no snow on the ground and winds arent likely to be calm for very long. So I am leaning toward the 10 degree mark for Sioux Falls. We will see how it plays out but anyway you slice it, it's going to be cold so bundle up tonight!
