Scattered to numerous showers and thunderstorms developed along and ahead of a cold front across much of East Texas during the morning and afternoon of April 20th. While surface based instability was weak, very steep lapse rates aloft coupled with increasing forcing aloft resulted in isolated severe thunderstorms over portions of East Texas, which resulted in several reports of large hail. The severe threat shifted southward across East Texas from morning to afternoon, ending across Deep East Texas around mid afternoon as the air mass stabilized from widespread areas of showers with embedded thunderstorms.
