| Brief Description: EVENT NARRATIVE: A strong EF2 tornado hit the town of Rice damaging several homes, derailing train cars, damaging a school, and overturning cars on the interstate. The tornado began about 4 miles outside the town limits of Rice and first damaged two homes near NW 050 road. One of the homes was completely destroyed. About a mile and half later, the tornado struck another home causing the exterior walls to collapse and taking the roof off the home. Next, the tornado entered the town of Rice and moved over a train track derailing 11 train cars. One of the train cars ended up in the nearby baseball field of the high school. The baseball field and nearby football stadium was also damaged, and the softball field was completely destroyed. Power poles and bleachers were damaged at the football and baseball field. At the softball field, the fences, dugouts, scorekeepers stand, scoreboard, light poles, and bleachers were all destroyed. The tornado then damaged an intermediate school causing one wall to lean and peeling the roof off the gymnasium. Next, the tornado crossed Interstate 45 where it overturned a few cars and trapped some people. One 18 wheeler carrying a dump truck lost the dump truck which fell onto a car traveling in the other direction. The driver of the car sustained minor cuts. East of the interstate, the tornado damaged 4 more homes causing mainly roof damage to the homes. The roof damage east of the interstate was mostly EF1 intensity. A total of 4 persons were injured during this tornado. All were transported to area hospitals with minor, non-life threatening injuries. In addition to the structural damage, trees were snapped along the path of the tornado. The maximum sustained winds were estimated to be 135 mph. EPISODE NARRATIVE: Severe thunderstorms developed along and east of Interstate 35 in association with a dryline across north Texas. The storms produced large amounts of hail which damaged hundreds, if not thousands, of roofs. In Hunt County alone, emergency officials estimated nearly 500 homes had some form of roof damage. In addition, a strong EF2 tornado moved through Rice damaging the new intermediate school, several homes, derailing train cars and overturning vehicles on Interstate 45. A second EF0 tornado damaged 10 homes near Lone Oak. | |||||||||||

| Brief Description: EVENT NARRATIVE: A damage survey was conducted by a team from the National Weather Service Forecast Office in Fort Worth, and they found that a tornado formed near Kosse. The first sign of damage found by the survey team was uprooted trees along CR 662. The tornado took a north-northeast track and several areas of large uprooted trees were found along CR 660, CR 656, CR 644, FM 1246 and FM 147. Damage to barns, sheds, and roofs was also found in this stretch. Substantial damage was found along CR 635 were a home was struck, resulting in one fatality and several injuries. Portions of the roof were removed and an adjacent barn was heavily damaged. A barn was destroyed along the adjacent road CR 633. The next significant damage was along Highway 164 just west of Groesbeck, where several homes, barns, and trees suffered considerable damage. Numerous livestock were killed along the path. A total of about sixty homes and businesses were damaged in Limestone County, and it has since been designated a disaster area by the Governor. The tornado then continued north into Fort Parker State Park. Lack of damage here indicated that the tornado dissipated nearby. 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. | |||||||||||

M70PH, F80PH May 12, 2000 - Event Narrative A cold front moved into North Texas, and became stationary along a Bonham, Dallas, Hillsboro, Goldthwaite line. Numerous hail and wind reports were received. An F-3 tornado touched down near Lake Whitney in the late afternoon hours.The parent storm continued to develop on the south flank, resulting in a long lived wall cloud that moved south through southern Bosque, western McLennan, eastern Coryell, and western Bell counties.

| 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. 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 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.
