Large Tornado Strikes Southeast Kansas! (3/1/2007)

By: Robb Lawson

A very powerful low pressure system tracked out into the plains on Wednesday February 28th. Ahead of this system south winds transported an unusually moist airmass into Southeast Oklahoma, Eastern Kansas and Missouri. Image 1 is a surface map from noon on February 28th.

Storms erupted around 5 pm across Southeast Kansas. Ample low level moisture and strong upper level winds allowed the storms that developed to quickly become severe. Around 630pm one of the storms intensified into a supercell thunderstorm and shortly after started producing tornadoes. Image 2 is a radar image from 635 pm of the supercell. This is around the time the first tornado was reported with this storm in Woodson County. Image 3 is another radar image of this intense storm at 652pm in Northern Allen County. Shortly after this radar image, a spotter reported 3 tornadoes combining into one large wedge tornado.

Below are all of the severe weather reports from this early season severe weather outbreak:
