Meteorological synopsis.
December 28.
A moderate (4/5) risk was issued by the Storm Prediction Center for December 28, as a shortwave trough was expected to move through Texas and Louisiana, with the risk area also extending into Mississippi and extreme south bringing the expectation of large hail and multiple tornadoes, some being strong (EF2+). High dewpoints from in conjunction with daytime heating over Texas and Louisiana would lead to high levels of atmospheric instability. CAPE values were expected to reach 1500–2000 J/kg. Both a bowing quasi-linear convective system and discrete supercells were expected to form in the risk area. A high risk had been considered for central Louisiana into central Mississippi, but local National Weather Service offices advised against it. As the evening progressed, it was expected to shift into a powerful squall line with the potential to cause intense downburst wind damage in addition to embedded tornadic mesocyclones.

As a result of the event, four people have been confirmed dead as of December 28. The only tornado-related death occurred in Brazoria County, Texas, about 30 miles south of Houston. Additionally, at least six people were injured across the affected areas.
