Summary: On April 11th, a line of heavy showers and scattered thunderstorms extended just ahead of a cold front at 10 am (see below, left). As the late morning and early afternoon hours progressed, breaks in cloud cover increased instability as the cold front pushed east into northwestern Alabama. This line quickly intensified shortly after 2 pm, as it moved into north central and eastern portions of Alabama. Scattered severe thunderstorms occurred along the line between 2 pm and 7 pm, creating straight line wind damage,small hail, and two weak tornadoes in the Huntsville area.
