The episode as NWS SHV wrote it up.
Numerous showers and thunderstorms developed throughout the morning and afternoon of July 26th, ahead of a weak surface front and associated upper level disturbance which moved across the region. Surface low pressure developed during the early evening hours along the surface front, and enhanced the development of stronger convection across a warm and moderately unstable region in Southeast Oklahoma and Southwest Arkansas. These storms quickly became severe and produced damaging winds which downed trees and power lines across this region before diminishing over extreme North Central Louisiana by late evening. A secondary cluster of severe thunderstorms developed over Northwest Louisiana near this surface low and front, which surged southeast across West Central Louisiana during the late evening and early morning hours of the 26th-27th. Damaging winds again downed trees and power lines across these areas, before weakening prior to sunrise.
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 Jul 26, 3:23 PM CST, 5 hours 12 minutes earlier.
