An upper level disturbance moved eastward across the Southern Plains during the late afternoon hours of April 19th.  Accompanying the upper level disturbance was a dry line that encountered strong instability across Northeast Texas, Southwest Arkansas and Northwest Louisiana.  Once the cap was broken in the afternoon hours, deep layer shear values near 40kts were supportive of discrete supercell thunderstorms.  Lapse rates were dry adiabatic and given the low wet bulb zero heights across the region, large hail was the main threat with these storms.
