Severe Weather Outbreak

April 14, 2011

 

 

 

What happened: A line of severe thunderstorms produced a few brief tornadoes, several funnel clouds, quarter to tennis ball sized hail, and 70 mph winds on the evening of Thursday, April 14th, 2011.

 

Background: A powerful spring storm system over the Rocky mountains moved east and strengthened across the High Plains  on April 14, 2011.  Thunderstorms rapidly developed by mid-afternoon along a dryline extending from southern Kansas to Texas. With abundant instability and wind shear, the storms became severe and moved rapidly northeast across central and southeast Kansas. Thunderstorms initially developed near the intersection of the dry air behind the dryline and the moisture which surged north from the Gulf of Mexico.
