From the mid-morning through the mid-afternoon hours on December 16th, 2019, a strong cold front progressed from west to east across the Four State region, ahead of a strong upper level trough which progressed east across the Southern Plains. Just ahead of the front, several severe thunderstorms formed in the unstable and highly-sheared air mass in place over Deep East Texas, Central Louisiana, and the Ark-La-Miss. The most potent storm produced a long-track EF-1 tornado that initially touched down in central Bossier Parish and tracked over 26 miles, before lifting in far west-central Claiborne Parish. Along most of its track, the tornado passed over rural areas and most of the damage was limited to trees. However, in east-central Webster Parish, the tornado either severely damaged or destroyed several residences, but fortunately, there were no reported casualties. A few other storms produced relatively minor wind damage in Northern Louisiana, limited to downed trees and power lines. This local event was on the northwestern edge of a large regional tornado outbreak affecting Louisiana, Mississippi, and Alabama.

Reported by: NWS Storm Survey

An EF-1 tornado with estimated maximum winds near 110 mph touched down in Central Bossier Parish north of the Red Chute community on a private extension of Crouch Road on the edge of Bayou Bodcau. Here, the tornado did significant damage to a few metal sheds and downed numerous trees (including a few hardwoods), snapping and uprooting their trunks. The tornado then tracked northeast and crossed Bellevue Road and Highway 157 where the damage remained confined to trees. The tornado then paralleled, but remained just southeast of Cotton Valley Road, before it crossed International Paper Road, downing additional trees. The tornado then crossed over into Webster Parish. Although the higher tornadic winds were found in Central Webster Parish, estimated wind speeds from this EF-1 tornado throughout Bossier Parish consistently ranged from 90-100 mph.

This is a continuation of the Bossier Parish EF-1 tornado. This tornado, with estimated maximum winds near 110 mph, tracked northeast across Fuller Road, with damage confined to trees as it moved over Bayou Dorcheat and over Dorcheat Road. The tornado then crossed Highway 371 and Couchwood Road, where additional trees were snapped and uprooted, with a portion of one tree responsible for minor damage to a shed off of Couchwood Road. The tornado then moved across heavily wooded areas in Central Webster Parish that was inaccessible by vehicle, but tornadic debris signatures from doppler radar remained consistent within the tight rotation in the favorable area of the storm to suggest that it remained on the ground where it crossed Mims Road, where several hundred hardwood and softwood trees were snapped and uprooted. The tornado continued to Evergreen School Road where two single family homes and their sheds were significantly damaged. A brick home lost most of its roof and as the roof was torn off, it toppled a brick wall. The damage to the brick wall was not rated up to an EF-2 as it occurred due to impacts from the removal of the roof and not the direct winds of the tornado. However, it was here where the tornado was strongest, with estimated maximum winds near 110 mph. The second home also had most of its roof torn off. The tornado then crossed Highway 159, where it picked up a single wide mobile home and carried it approximately 50 yards, with the undercarriage separating from the rest of the home and wrapping it around a tree. The rest of the mobile home was destroyed when it landed. Three other nearby mobile homes suffered minor damage to their roofs and/or carports. The tornado showed signs of weakening in the tree damage indicators after it crossed Angi Road and into Western Claiborne Parish.

This is a continuation of the Webster Parish tornado. This EF-1 tornado, which had weakened as it entered Western Claiborne Parish, had estimated maximum winds near 90 mph, as it crossed Grigsby Loop and Flat Lick Road, where additional trees were snapped and uprooted. The tornado finally lifted along Line Road, but not before remaining on the ground for over 26 miles since initially touching down in Central Bossier Parish.
