An impressive cold front and post-frontal moisture brought a batch of light snow to portions of Middle Tennessee on January 20, 2019. The previous day, January 19, started with rain and overcast conditions, which halted for a period of time in the early afternoon hours. Sunshine and blue skies returned for a short period of time in the middle of the afternoon, before quickly returning to an overcast sky. A sharp and well-organized line of moderate to heavy showers pushed through the Mid State directly ahead of the approaching cold front. 

While temperatures were falling rapidly behind the front, additional moisture on the back side of a low pressure system was swinging southeast toward Middle TN. By late evening into early Sunday (1/20), temperatures west of I-65 were already in the 30s and continuing to plummet. Eventually, the aforementioned moisture caught up with the intrusion of cold air and produced measurable snowfall, mainly along and north of the Interstate 40 corridor. Amounts ranging from a few tenths of an inch to around 2 inches of snow fell, with the greatest amounts in northwestern Middle Tennessee (Clarksville area). This activity exited east and left behind a frigid air mass, where temperatures dipped well into the 20s and wind chills reached into the teens.
