The combination of instability – warm, humid air near the surface overlaid by cold, dry air aloft – and wind shear in the atmosphere, particularly at low levels crucial for the spawning of tornadoes, was quite simply in another realm on April 27, 2011. Meteorologist and researcher Jon Davies bloggedabout the rarity of seeing such extreme values of ...
It not uncommon for a morning cluster of severe thunderstorms to be followed by a more dangerous round of afternoon supercells. The morning thunderstorm cluster typically produces damaging winds, flooding rain and perhaps a few tornadoes. An early-morning squall line in the Tennessee Valley on April 27, 2011, produced an incredible 76 tornadoes in ...
Because of these three rounds of severe thunderstorms, some locations were hit multiple times on April 27. Cordova, Alabama, northwest of Birmingham, was just one unfortunate example. Around 5:20 a.m. CDT, a tornado intensified quickly as it tracked into the city of just over 2,000 residents. Damage there was rated EF3 on the Enhanced Fujita scale....
Perhaps the most indelible live coverage of this Super Outbreak was the split-screen shown on ABC 33/40 in Birmingham, Alabama, showing both a live-cam shot of a wedge tornado roaring through Tuscaloosa, Alabama, as meteorologist James Spann was showing the classic hook echo and debris ball (indicating tornado-lofted debris) on radar. In roughly 90...
The term supercellrefers to a rotating thunderstorm that is persistent, on a time scale much longer than a single, ordinary thunderstorm you may see, for instance, in the summer over the Southeast. The Knupp et al. studydocumented three prolific long-track supercells on April 27. One supercell tracked over 500 miles in nine hours and spawned the Co...
The first of four EF5 tornadoeson April 27, 2011, raked through east-central Mississippi, leaving some incredible damage in its wake.
