A warm front began to lift north across East Texas and North Louisiana during the afternoon of April 13th, with warm, moist, and unstable air shifting back north across these areas. Meanwhile, a weak upper level disturbance in the zonal flow aloft helped enhance scattered thunderstorm development along and north of the front across portions of East Texas. Given the adequate shear and extent of instability aloft, isolated severe thunderstorms developed and produced reports of large hail across these areas before diminishing during the evening with the loss of heating. However, another more significant shortwave trough traversed the Red River Valley of Southern Oklahoma and North Texas, as the warm front shifted farther north across East Texas to near the Louisiana/Arkansas border. Large scale forcing ahead of this trough and elevated instability aloft resulted in an increase in shower and thunderstorm development during the early morning hours of April 14th, near and ahead of an associated cold front that had begun to enter the region from the northwest. A few isolated severe thunderstorms developed over portions of Northeast Texas, Southwest Arkansas, and North Louisiana, producing instances of large hail before these storms weakened and became more numerous after daybreak, before eventually diminishing from west to east by afternoon.
