Deteoriate, improve, deteoriate, improve

The featured graph is a time series from the Spencer airport sensor showing air temps, wind speeds, and visibility distance. The morning hours saw a round of snowfall followed by improving conditions where temperatures rose to above freezing in many locations followed by a frontal passage with rapidly deteoriating conditions followed by a decrease in wind speeds with improving visibilities by bitterly cold temperatures. All of that makes for quite the weather day! The next winter storm will be here this evening already!

Good = 23
Bad = 6
