What happened

The episode as NWS SHV wrote it up.

A deep southwesterly flow aloft ahead of a large upper trough of low pressure exiting the Rockies into the Central and Southern Plains spread across the Ark-La-Tex area during the afternoon hours on November 26th. A few small supercell thunderstorms developed in a region of strong low-level warm air advection ahead of an approaching cold front. The environment was characterized by low instability, but high wind shear. These cells briefly exhibited rotation across portions of Northwest and Northcentral Louisiana, but most of the couplets were very short-lived, usually lasting only about 10-15 minutes. One of these storms did produce a brief tornado in Northwest Claiborne Parish between Homer and Haynesville, before the storms weakened by mid-evening.

An EF-1 tornado with estimated maximum winds around 95 mph briefly touched down at the intersection of Bell Hill Road and Krause Road, where it produced sporadic damage, uprooting and snapping five trees. The tornado continued northeast on to a residential area of mobile homes on the grounds of the David Wade Correctional Center. The most concentrated damage was found near the gun range, with a well-defined convergent damage swath with hardwood and softwood trees snapped and uprooted along its path. Minor roof damage was observed to a double-wide mobile home and the top of a tree which fell onto a travel trailer. The tornado then went on to snap and uproot additional trees and lifted after it crossed a pond on the grounds of the correctional center. An estimated 30 trees were downed along the path of the tornado.
