F2 tornado in Hill County, Texas

The National Weather Service in Fort Worth conducted a damage survey and found that a tornado developed west of FM 933 and south of CR 1145. Tree damage was noted as the tornado crossed FM 933 and FM 67 one mile southeast of Blum. The tornado apparently increased in size and intensity after crossing FM 67. A large grain silo was toppled over on CR 1137, roughly 1.5 miles northeast of Blum. Extensive tree and power pole damage was also noted. The path width was over a quarter of a mile at this time. As the tornado crossed County Roads 1136 and 1133, widespread tree damage was noted, as was structural damage to roofs and windows. The tornado then moved across FM 2488 just south of the Johnson County line, where a well-engineered home lost portions of roof decking and a large barn was destroyed. Portions of the barn's metal skin were carried over a mile to the north-northeast. The tornado then crossed into Johnson County.

A rare winter tornado outbreak occurred on December 29 over portions of North Texas, spawning almost two dozen tornadoes. Very high shear and low instability created an environment favorable for tornadoes. A strong surface low pressure system and warm front located in southern North Texas increased the probablitity for low-level rotation. In addition to tornadoes, severe reports of large hail and flash flooding were widespread.
