A deep southerly flow increased across much of the Ark-La-Tex during the daytime hours of April 30th through May 1st, ahead of a slow moving upper level trough that drifted east into the Southern Plains from the Four Corners Region. A complex of showers and thunderstorms that developed over Western and Central Oklahoma during the evening of April 30th ahead of a stalled surface frontal boundary sent a cold pool southeast into portions of extreme Northeast Texas and Southwest Arkansas which eventually stalled out during the early morning hours on May 1st. Weak upper level disturbances in the southwest flow aloft ahead of the approaching trough triggered additional showers and thunderstorms across Northcentral Texas, which spread east northeast across East Texas, Southwest Arkansas, and North Louisiana during the evening hours of the 1st, and continued throughout the morning hours of the 2nd. The earlier stalled boundary over Northeast Texas and Southwest Arkansas helped to enhance the showers and thunderstorms, and coupled with the instability and deep moisture in place, some of the showers and thunderstorm became severe, producing large hail, damaging winds, and locally heavy rainfall. An isolated tornado even touched down across Eastern Shelby County Texas just prior to daybreak on the 2nd. Where the storms moved repeatedly over the same areas, flash flooding was observed with several roads flooded and closed across portions of East Texas.
While the storms diminished shortly after daybreak on the 2nd, another complex of showers and thunderstorms developed during the late afternoon through the evening hours in Central and Southeast Texas ahead of another shortwave trough, with a portion of this complex migrating into Deep East Texas by mid-evening. Given the moderate instability in place across this area due to strong daytime heating, some of these storms also became severe, with damaging winds downing trees and destroying a chicken house in Northern Nacogdoches County before weakening by late evening.
