Warmth

Well, if you are sick of the cold already, I have some good news for you. We well be warming up starting tomorrow and finishing Wednesday. I know its not going to be for the weekend when most people want nice weather but I think for this time of the year, we will just have to take what we can get. The three pictures below are from just one of the many forecast models that we look at on a daily basis to determine the weather in South Dakota. These are in succession starting today at noon, tomorrow at noon, then Wednesday at noon. You can see the drastic warmup of temperatures at 850mb (5000 ft).

This is what we use to determine temperatures at the surface. When there is a warm up expected above the earth's surface, then that typically will correspond to a warm up at the surface as well. Now, to get the really warm air, we would need to bring this 5000 ft air down to the ground because sinking air compresses and heats up. Well, at this point, the atmosphere doesn't look like its going to be very efficient in doing so. So that means, temperatures wont be warming up as much as they could. Never the less, warmer air can still be anticipated. And with us now into the middle of November, any warmer air that we can get is a plus. Enjoy!
