A series of weather systems brought several rounds of winter weather to South Central Texas from February 11 through February 18. The first episode of winter weather started when a cold front moved through South Central Texas on February 10 and stalled over South Texas. This brought cold air to the region and once it was in place, a combination of isentropic flow over the frontal boundary and an upper level shortwave trough produced sufficient lift to produce precipitation. With warm air above the boundary layer and sub-freezing air near the surface, the precipitation fell as freezing rain.
