EF1 tornado in Lafourche Parish, Louisiana

Another embedded mesocyclone embedded in the squall line produced a tornado. Tree damage was noted across a field west of Louisiana Highway 20, and due to lack of road access, this was determined to be the start point of the tornado. Several large trees were uprooted along the tree line. Damage was noted as EF-1 in this location. The tornado then moved east-southeast across the field, and crossed Louisiana Highway 20 at the intersection with Appletree Drive. EF-1 damage was noted here, and the tornado was approximately 75 yards wide at this point. A small professional building had large portions of siding ripped off and shingles missing from the roof. Trees were uprooted in varying directions in front of the home, and several power poles were snapped at the base in this location. The tornado then moved east-southeast down Appletree Lane and removed a large portion of the shingles from several homes. Several trees were also uprooted and snapped in this area. High end EF-0 and low end EF-1 damage was noted along Appletree Drive. At the end of Appletree Drive, a detached garage collapsed. The tornado then continued into the woods where a path was noted for several more yards with trees uprooted and snapped. The tornado remained 75 yards wide and maintained EF-1 strength as it moved into the woods. It is unknown if the tornado continued further into the woods due to a lack of access.

A strong upper level low over the southern Rockies aided in the development of surface low pressure over north Texas on the 26th. As this low moved east along a stationary front over Louisiana and Mississippi, a strong line of thunderstorms developed during the early morning hours of the 27th. This line of storms moved rapidly across southeast Louisiana during the daylight hours of the 27th. Numerous reports of thunderstorm wind damage were received, primarily downed trees and power lines. Several meso-cyclones embedded in the southern potion of the squall line spawned weak tornadoes.
