| Episode Narrative | A deep longwave trough remained anchored over the Central and Southern Rockies on May 20th, with a deep southerly fetch of low level moisture continuing to maintain an ample moisture-rich environment over the Four State Region. Diurnal heating contributed to air mass destabilization during the afternoon, with disturbances aloft contributing to scattered shower and isolated thunderstorm development across the area. Low level shear increased during the afternoon, and helped foster the development of isolated severe thunderstorms across portions of East Texas, with isolated tornadoes briefly touching down across Western Angelina and Western Harrison Counties. A localized pocket of damaging winds also resulted in large limbs being downed near Lufkin, and a porch being damaged as well. These storms eventually shifted north into Southeast Oklahoma during the evening. |
| Event Narrative | An EF-1 tornado with estimated maximum winds near 100 mph touched down on the south end of a large property along Old Bonner Road and tracked north-northwest for at least an estimated 2.5 miles through rural areas of Northwest Angelina County. Much of the damage was observed in this large property area, with damage mainly confined to numerous trees being uprooted, trunks snapped, or losing large branches. One outbuilding did receive minor damage on the outskirts of the tornado on this property. The tornadic damage extended as far as the eye could see south of the south boundary of the aforementioned property, although access to survey farther south was unavailable due to a lack of road access. The tornado continued north across Blackburn Switch Road, where a narrow swath of EF-0 tree damage was observed. This was judged to be the ending point of this tornado due to the lack of access to roads farther north, just south of Highway 103. |
