4 Tornadoes on April 27, 2017

Event Summary for Central Alabama

A pre-frontal trough moved into Central Alabama on Tuesday night, April 26th. This boundary slowly pushed southward and was accompanied by some showers and thunderstorms. The thunderstorms produced severe weather back west across Mississippi, Arkansas, Louisiana and Texas. This boundary appeared to lose upper level support and the instability was limited. The east to west boundary drifted into south central Alabama and into Georgia on April 27th. The combination of shear, lift along the boundary, increased low level moisture and instability produced by insolation was just enough to spin up a few weak tornadoes.

The information contained below is from the 4 individual tornado events that occurred. The data is PRELIMINARY and may be subject to change.
