A series of weather systems brought several rounds of winter weather to South Central Texas from February 11 through February 18. The next round of winter weather came February 16 and 17. A surface trough developed along the Texas coast and an upper level jet streak moved over the top of it. This created warm advection above the boundary layer and another round of freezing rain over the eastern half of the area. The final episode of winter precipitation came February 17 and 18. The main upper trough axis moved across Texas and cooled the deeper atmosphere. The height falls led to upward motion that produced precipitation. A few spots had a mix of wintry precipitation at the start of this episode, but it all turned quickly to snow.
