		Brief Description: EVENT NARRATIVE: A storm survey conducted by the National Weather Service in Fort Worth found that a tornado touched down in the town of Crowley near Sharondale Drive and Morfield Drive. Damage was mostly confined to these two streets where two houses lost significant portions of their roofs and received damage to external walls. Two houses had portions of roof decking removed and several metal storage buildings were damaged. Several additional homes suffered minor roof damage and nearby trees had large limbs broken off. This tornado was rated an EF-2 with maximum sustained winds of 110-115 MPH. EPISODE NARRATIVE: North Texas was impacted with a linear mesoscale convective system as well as discrete supercell thunderstorms during the afternoon and evening hours. An EF-2 tornado destroyed several homes in the town of Crowley and several other brief tornadoes were reported as well. Other severe reports included large hail and damaging winds.

		Brief Description: EVENT NARRATIVE: 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. EPISODE NARRATIVE: 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.

		Brief Description: EVENT NARRATIVE: The National Weather Service in Fort Worth conducted a damage survey and found that the tornado which originated in Hill County continued on its destructive northeast path into Johnson County. Damage to sheds and vegetation was noted along County Roads 1205 and 1204. The most significant damage to structures was found near FM 916, CR 1202, and CR 1205, northeast to near Highway 171. Several structures were unroofed while others suffered partial roof loss. Major damage to trees was also noted here. Damage to homes and trees continued along the track near CR 421, CR 423, and CR 415 just north of Highway 4. The tornado then crossed FM 2415. The last observed damage was along the south shore of Lake Alvarado. County officials reported that twenty-two residences were destroyed, twenty were heavily damaged, and twenty more had minor damages. Ten people were taken to local hospitals. Most were for minor injuries, but two suffered more serious injuries and were released from the hospital the next day. The Governor designated Johnson County a disaster area.

		Brief Description: M52OU, M67OU Tarrant County Thunderstorm Narrative The first tornado damage was reported near Castleberry High School, about four miles west of downtown Fort Worth (618 PM). Additional roof and tree damage occurred in Monticello neighborhood of River Oaks. A number of businesses were then damaged or destroyed near the intersection of Camp Bowie and West Seventh (620 PM). Tornado moved east along West Seventh Street, striking the Montgomery Ward building and the adjacent Linwood neighborhood, doing extensive damage to older homes (622 PM). The tornado then did extensive damage to the six story Cash America building, nearly destroying it. Further significant damage was then done to the Mallick Tower building and Calvary Cathedral Building (624 PM). The tornado weakened as it entered downtown, but wind borne debris broke thousands of windows in buildings and high rises (626 PM). Particularly hard hit was the Bank One Building, which had 80% (3,000) of its windows broken, and the Union Pacific Resources Building (1,300 of 5,000 windows broken). Numerous other structures were affected to a lesser degree. Automobiles in streets and parking lots were also damaged. The tornado then dissipated as it moved east of downtown, although scattered minor damage occurred to roofs, trees, fences, and billboards about 3 miles east of the city near I-30 and Brentwood Stair. Two people were killed as a direct result of the tornado. A man (age 52) was killed while trying to reach shelter after warning others of the tornado, while a homeless man (age 67) was killed by a wall that collapsed on him. Some 80 other people were injured, but only six required hospitalization. Hail did extensive damage to roofs and autos mainly in Lake Worth and Saginaw. Initial tornado damage in Arlington occurred at a restaurant on South Cooper street. The tornado moved east and gained strength, doing F3 damage near Bardin and Matlock (707 PM), south of I-20. The tornado then struck the northern part of Arlington Airport (F2). The tornado paralled I-20, crossing the Interstate about one mile west of Highway 360, overturning at least one 18-wheeler (F1)(712 PM).
