A late-season blast of cold air brought sub-freezing temperatures to some areas on the night of the 20th. Lows ranged from 31 to 34 degrees. The arrival of the cold air was heralded by some light snow on the evening of the 19th. Accumulations ranged from a trace to an inch, mainly on grassy and elevated surfaces. At Paducah, this was the latest measurable snowfall on record. The snow had no societal impact. There were no immediate reports of crop damage due to the cold air. A strong cold front moved southeast across the region on the evening of the 19th. A low pressure system then moved northeast along the front, passing over the Tennessee Valley on the 20th. Gusty north winds on the back side of the low ushered in the cold air.
