A trough of low pressure spread east across the Southern Plains during the evening hours of January 15th, with a arctic air mass quickly spilling south into the Ark-La-Tex during the late afternoon through the evening hours behind a strong cold front. Scattered areas of light rain developed along and just behind the front over much of East Texas and Northcentral Louisiana during the evening hours, with the rain quickly mixing with sleet and changing over to snow during the early morning hours on the 16th. While the mixed wintry precipitation melted during the beginning of the event, temperatures fell quickly into the mid 20s by or shortly after daybreak on the 16th, resulting in some black ice developing on some primary and secondary roadways, bridges and overpasses, with snowfall accumulations of a half inch to an inch and a half, with isolated higher amounts atop of the ice. This caused some travel impacts across these areas of Northcentral Louisiana, before the snow ended by mid-afternoon and temperatures warmed enough to melt the snow and ice across the more traveled roadways.
