Severe Weather on September 21-23 2006 (Pg1)
 
A strong storm system headed from the Rockies into the Plains on September 21st. The system dragged a cold front toward Arkansas, with the front pushing through on the 23rd. Ahead of the front, warmth and moisture increased markedly...with several rounds of strong to severe thunderstorms.

In the picture: By the evening of 09/22/2006, the system headed toward the Dakotas...with lots of wind energy aloft and copious moisture in place (dewpoints in the 60s/70s).
 
Storms began firing during the evening of the 21st. Dewpoints (a measure of moisture in the air) increased from the 50s into the 60s/lower 70s...especially in western Arkansas.

 

The satellite showed swirling clouds in southeast Nebraska at 10 pm CDT on 09/21/2006, with the clouds associated with a storm system aloft. There was also a lot of shear, with a southeast wind at ground level and a strong southwest wind aloft. As the wind turned with height, storms showed signs of rotation.

Farther east, storms that popped up during the early morning hours of the 22nd were not as potent...but were still severe. Penny size hail was produced at Haskell (Saline County), with power lines downed at Batesville (Independence County).

 

Later on the 22nd, strong shear was displaced into northern Arkansas and areas farther north (such as Missouri and Illinois) as the system in Kansas headed for the Dakotas. Tornadoes were most likely in these areas, and less of a concern farther southwest. A severe (and potentially tornadic) storm was seen in Newton County from Eureka Springs (Carroll County) around 630 pm CDT on 09/22/2006.
