Wider weather episode

A line of storms with embedded supercells developed south of an outflow boundary ahead of a slow-moving cold front, producing damaging winds and several tornadoes across the northern portions of central Alabama during the evening hours on December 29th. The surface boundary shifted into the southern counties of central Alabama on December 30th. The low level shear was not favorable for tornadoes, but the storms were robust enough to produce damaging winds and large hail.
