Tornadoes from February 28th, 2011

Multiple Tornado Event - February 28th, 2011

Event Summary for Central Alabama

On the afternoon of Sunday, February 27th, a low pressure system developed in the Southern Plains, eventually tracking across the Tennessee Valley, well to the north of Alabama. In response to this low pressure, coupled by high pressure off the Atlantic Coast, southerly flow brought low 60 dew point temperatures as far north as Huntsville by 12 am Sunday night. By the late morning hours of Monday, February 28th, a secondary surface low developed and tracked across the northern half of the state of Alabama. This surface low created storms that began of a cellular nature by Noon on Monday. These cells evolved into a broken line of thunderstorms by the middle of the afternoon on Monday. Embedded in the line were storms that developed supercellular structures, a few of which spawned tornadoes and many areas of straight line wind damage. Click on each for a summary of the tornadoes.
