The tornado lifted on the northern end of Kit McConnico Park around 10:07 PM. EPISODE NARRATIVE: A strong upper level storm system moved its way out of the southern Great Basin and into the Southern Plains during the afternoon hours of December 23rd. Strong southerly flow was found ahead of this storm system with dewpoint temperatures in the lower to middle 60s noted northward to the Interstate 20 corridor of northeast Texas and northern Louisiana. Impressive deep layer shear was noted in the warm sector across the region which was conducive for discrete storm cells during the afternoon and evening across northeast Texas. These storms spawned tornadoes and produced large hail across portions of northeast Texas. The storm system moved eastward during the predawn hours of December 24th with again, numerous storms producing tornadoes across southern Arkansas and northern Louisiana. In addition to all the storm damage...these storms were prolific rain makers with numerous reports of flash flooding across the region as well.

 Brief Description: EVENT NARRATIVE: The tornado first touched down in a wooded area west of Ireland Williams Road. The tornado quickly intensified as it approached Interstate 20 near mile marker 628 where 2 businesses were destroyed on both the south and north services roads. One of the businesses was a metal building and the other was a mobile home. One home was completely destroyed with only a few interior walls remaining. A second home sustained major damage to the roof and carport. Debris was scattered across interstate 20 and Hwy 80. Several other homes were damaged further east along both sides of the service road. Many trees were snapped and uprooted in the area???some were snapped down close to the base. The tornado continued northeast crossing Bellview Road into Jonesville, TX where a grocery store roof was peeled and walls were blown out of a large warehouse. The tornado also damaged some metal buildings north of Jonesville along FM 134. The tornado tracked east across a wooded area snapping and uprooting trees crossing FM 9 headed east into Caddo Parish in LA. Maximum winds are estimated at 150-160 mph. EPISODE NARRATIVE: A very warm and unstable air mass developed across the region on January 20th. This air mass was accompanied by unusually high dewpoint values for late January with ambient temperatures approaching the 70 degree mark. A very strong and vigorous storm system moved out of the Great Basin and into the Southern Plains and Lower Mississippi Valley during the late afternoon and evening hours of January 20th. Wind shear throughout the atmosphere was very strong and supportive of strong to severe thunderstorms. Low level wind shear was significant enough such that super cell thunderstorms developed across the region, producing tornadoes, large hail and damaging wind gusts.
