A dry cold front pushed south down the eastern Colorado Plains and western Kansas during the evening of 4 Nov into the early morning hours of the 5th. The push of cold air is captured nicely in GOES-16 IR Window channel imagery (Fig. 1). Additionally, the hourly-updating GOES-16 Land Surface Temperature product shows the cooling surface temperatures (in clear sky areas) behind the cold front (Fig. 2).
