Who would have thought that at the end of December we wouldn't have temperatures cold enough to generate snow? Now if we would have had temperatures like the ones we're going to get early next week today, we would have likely been dealing with a good amount of snow! Once this low passes another fast moving 'clipper' type system will move through the Plains and upper Great Lakes. Southerly winds will increase late in the day Saturday helping give temperatures a boost into the low to mid 40s. A cold front will help ring in the new year early Sunday with temperatures falling into the lower 30s by the afternoon. Winds from the north will gust as high as 40-45 mph throughout the day and I wouldn't be surprised if a wind advisory were to be issued Sunday.
A true Arctic high pressure will move into the middle of the country late Sunday and that will not only help bring the cold, but also the very dry air. Dew point numbers can sometimes be used as indicators as to what the low temperature will try to fall to on clear, calm nights. Notice how dry the dew points are Monday and Tuesday; in the single digits! This means our temperatures early Tuesday and Wednesday morning hold a pretty good shot of falling into the upper single digits or low teens. It's only a quick shot of cold and then temperatures will warm closer to average towards the end of next week.
