Shortwave what?

16We are slated for a bit of snow late on Monday through Tuesday, but the system responsible for our wintry precip chances will not be a large low pressure system or a powerful cold front. Whats known as a shortwave is set to make a quick dash through the stateline. As many of you know, the jet stream is an area of quick moving air thousands of feet above the ground. This pattern has turned more zonal recently, which is more of a west to east flow, giving us daily temperature variations near normal values. When we get a slight deviation in this flow, as seen in the picture, this can add enough energy to our atmosphere to promote some light snow. At this time, an inch or two are possible out of this quick moving system before we see a slow rise in temperatures behind it.

    He he … “shortwave” … sounds like a radio frequency….

    Love those zonal jet stream patterns. It gives us a more “normal” winter, just enough new snow to cover up the old dirty grey snow and make the winter landscape pretty again.
