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 Northeast Texas and Northwest 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 lower 20s prior to daybreak on the 16th, resulting in extensive black ice development on many roadways, bridges and overpasses, with snowfall accumulations of one to two inches common across Northwest Louisiana atop of the ice. This caused significant travel impacts across portions of Northwest Louisiana, with national media coverage of the ice covered roadways which paralyzed much of this area.
