The episode as NWS SHV wrote it up.
A strong upper level trough shifted east into Western Texas and Oklahoma during the early morning hours of April 17th, entering Central Oklahoma and Texas during the afternoon. This trough allowed the dry line to mix east across Central Texas during the afternoon ahead of an associated cold front, while southerly winds increased across the Ark-La-Tex, returning warm, moist, and unstable air back north across much of the region. Large scale forcing increased across East Texas, Southeast Oklahoma, Southwest Arkansas, and North Louisiana during the evening through the early morning hours on the 17th-18th, resulting in showers and thunderstorms becoming more numerous while spreading north northeast across the area. Steep mid level lapse rates and strong wind shear had spread east across the region ahead of the trough and associated cold front, such that scattered strong to severe thunderstorms developed, resulting in damaging winds which downed trees across portions of Shreveport, as well as in the Cloutierville community in Southern Natchitoches Parish. These storms weakened by mid-morning and diminished from west to east during the daytime hours on April 18th, as the cold front had pushed through the area returning cooler and drier air into the region.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Shreveport, LA wrote its last area forecast discussion before the first event at Apr 18, 2:25 AM CST, 2 hours 1 minute earlier.
