Showers and thunderstorms developed over Eastcentral Texas and Southeast Oklahoma during the afternoon hours of May 11th, ahead of a positive tilt upper trough that shifted east across Northern Oklahoma and Southern Kansas. The dryline managed to mix east to near the I-35 corridor by late afternoon, before a cold front associated with the upper trough overtook the dryline and shifted southeast into Southeast Oklahoma an extreme Northeast Texas late. The air mass ahead of the front became moderately unstable by mid to late afternoon, with upper forcing ahead of the trough contributing to an increase in strong to severe thunderstorms across much of East Texas and North Louisiana. Damaging winds and hail were common with the stronger storms, with even isolated tornadoes also spawned across portions of East Texas and Northern Caddo Parish in Northwest Louisiana. These storms weakened by late evening with the loss of instability.
