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: A
storm system ("L") was in northern Kansas late on
09/21/2006, with winds aloft (30,000 feet shown) increasing around the system and
moisture drawn toward the system from the Gulf of Mexico (dewpoints
climbing from the 50s into the 60s/lower 70s). |
|
|
| 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. |
 |
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. |
| In the picture:
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. South
of the system, severe thunderstorms were in western Arkansas. |
| One storm in particular tracked from Polk County into
Montgomery County, with Tornado Warnings issued by the National Weather
Service. |
|
| In the picture: The
WSR-88D (Doppler Weather Radar) showed a severe storm just south
of Mena (Polk County) at 1030 pm CDT on 09/21/2006. |
|
|
A weak (F1) tornado was spawned just north of Wickes
(roughly 20 miles south of Mena in Polk County). Trees were also downed around Grannis (Polk County) and Welsh
(Montgomery County), with tin off of a chicken house at Bogg Springs (Polk
County). |
| In the picture:
The storm just south of Mena (Polk County) was rotating, with a Tornado
Warning issued. |
| 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. |
 |
| In the picture:
A severe (and potentially tornadic) storm was seen in Newton County from
Eureka Springs (Carroll County) around 630 pm CDT on 09/22/2006.
