An upper level low pressure system slowly ejected northeast across the piney woods of East Texas during the evening through the morning hours of May 10th-11th. A southerly low level jet present ahead of the low spilled copious amounts of low level moisture north into East Texas and Western Louisiana, with strong large scale forcing ahead of the low enhancing numerous shower and thunderstorm development which moved repeatedly over these areas throughout much of the overnight into the early morning hours. Widespread rainfall amounts of 2-4+ inches fell across much of North Louisiana during the morning through the early afternoon hours on the 11th, resulting in instances of flash flooding across this area. Given the strong low level wind shear out ahead of the low, as well as increased instability especially with the onset of daytime heating, severe thunderstorms containing damaging winds, while also spawning a few isolated tornadoes, were observed throughout the morning as well before eventually diminishing during the afternoon.

Most of the damage was limited to tree limb damage and tree uproots, although a few structures were damaged by falling limbs.

A tornadic debris signature for the Shreveport dopplar radar was coincident with the majority of the tornado's track.

Tornado in DE SOTO, LOUISIANA
From 11-MAY-23 06:55:00 to 11-MAY-23 06:56:00 (CST-6)
Location: HUNTER
Tornado F-scale: EF1

Crop damage: 0.00K
Reported by: NWS Storm Survey

A EF-1 tornado with estimated maximum winds near 100 mph, briefly touched down along the west and east sides of Highway 763 a couple miles south of Stanley. Along its brief path, several softwood trees were snapped but multiple hardwood and softwood trees were uprooted. An outbuilding and a single family home on the west side of the road sustained roof damage by wind impacts alone. There was also minor wind damage to a single-wide mobile home on the east side of the road. A tornadic debris signature
from the Shreveport dopplar radar was observed with the surveyed damage, but also continued about a mile farther east. This suggests that the tornado probably continued on farther east for some distance after the end of the surveyed track, although the NWS survey team had no ground access to survey points immediately to the east.
