ILLINOIS SEVERE THUNDERSTORMS AND TORNADOES - FROM THE NWS IN CHICAGO
Severe Weather Radar Images from September 22, 2006
Selected Radar Images from September
22, 2006 Severe Weather
Severe thunderstorms developed over northern Illinois and the Chicago metro
region during the afternoon of September 22nd during the afternoon
rush hour. These storms were related to a complex and strong early autumn
cyclone over the northern Plains. The primary areas affected extended from
southern DeKalb County eastward across portions of Kane…DuPage and Cook
Counties including the City of Chicago
While widespread wind damage, areas of flooding and some large hail were
reported in these areas the potential for a serious tornado event was narrowly
averted. The environment that afternoon had a number of characteristics which
would have supported tornadoes including instability, strong winds at mid
levels and a favorable low level wind profile. A number of funnel cloud
reports were received from the storms but no ‘tornado’ occurrences can be
verified at this time.
Radar signatures with these storms reflect the
potentially serious nature of the threat. A
four-panel reflectivity display at 511PM CDT
show a series of 3 storms extending from O’Hare Airport west into DeKalb
county. The upper left image is the lowest elevation (0.5 deg beam height)
while the upper right is at 1.5 deg, lower right at 2.4 deg and lower left is
at 3.1 deg. Beam height at the distance of the storms (1,2,3) are 1300ft to
2000 ft above ground for 0.5 deg and 3500ft -5000ft for 1.5 deg. The circles
outline the dangerous portion of the storms where rotation was detected. Note
the appendage from the storm just north of O’Hare. This has the appearance of
a classic ‘hook’.
The
storm relative motion
(forward motion of the storm subtracted from the overall motion) sequence at
the same time details the air motion…green being toward the radar and red
being away from the radar. [Purple is undetermined]. There is variation of the
signature with altitude but the key element is green directly adjacent to red
along the beam…indicating rotation The image below was taken about 5 miles
south of Dekalb by Thomas Zerebny. It is the third storm in the 4 panel image
referenced.

Strongest September tornadoes on record in our region
occurred Fri., Sept. 22...up to F-4 intensity.
Damage surveys revealed the
long-track tornado across Perry County, Missouri into Jackson County, Illinois
on Sept. 22 reached F-4 intensity. Preliminary data indicates the tornado was a
low-end F-4 with peak winds of 210 MPH in Perry County. The F-4 classification
ranges from 207 to 260 MPH. The tornado damage in the Jackson County portion of
the path was rated F-2.
- Until Friday, Sept. 22, the strongest September
tornadoes on record in the 58 counties assigned to the Paducah office were F-2
intensity. The Massac County, IL F-3 tornado and the Perry County, MO F-4
tornado on Sept. 22 were the strongest on record for the month of September,
including unofficial records going back to 1880.
Click on map below for larger version of
preliminary tornado path map. Additional tornado paths will likely be plotted.
Tornado damage was recently confirmed by a survey in Crittenden and Webster
Counties of Kentucky. Other possible tornado damage is in eastern Ballard County
near Oscar and in Pope County, IL.

NATIONAL WEATHER SERVICE - LITTLE ROCK INFORMATION
http://www.srh.weather.gov/lzk/html/svr0906a.htm
SEPTEMBER 21 START OF EVENT
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.
Trees were 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.
SEPTEMBER 22-23 EVENT
True to form, scattered to numerous thunderstorms erupted near the Arkansas/Missouri border...with strong
rotation in many of the storms.
In the picture: The satellite showed storms erupting in
northern Arkansas during the afternoon of 09/22/2006.
In fact, 31 Tornado Warnings were issued for 10 counties in the Little Rock County Warning Area from 137 pm CDT to 1045 pm
CDT on the 22nd.
Severe weather reports from the SPC
At least two tornadoes have been confirmed in
eastern Izard and western Sharp Counties. Funnel clouds were spotted near
Mountain Home (Baxter County), just north of Harrison (Boone County) and near
Sidney (Sharp County).
There was also very large hail, with baseball size hail or larger just
south of Franklin (Izard County), near Brockwell (Izard County) and Ash Flat
(Sharp County).
In the pictures: Twenty four hour rainfall as of 7 am CDT
on 09/23/2006.
Thunderstorms continued forming over the same areas
into the early morning hours of the 23rd. This led to excessive rainfall in some
spots, with amounts over 6 inches reported. Hardy (Sharp County) received 8.20
inches of rain (twenty four hour amount as of 7 am CDT on the 23rd), with 6.75
inches at Corning (Clay County) and 5.10 inches at Salem (Fulton County).
Flash flooding occurred, with water rescues near Hardy (Sharp County).
Some people in this area were in trees to avoid the high water. One person
reportedly drowned. At Salem (Fulton County), water covered most of the main
roads around town...with major flooding at area campgrounds. A creek also
overflowed near Williford (Sharp County), with water over U.S. Highway 63.
Water will make its way into area rivers, with flooding along portions of
the Black, Cache, Spring and White Rivers.
Severe weather/heavy rain continued into the afternoon of the 23rd, with a
front advancing across the state. The wind did not turn so much with height,
with less shear overall (i.e. not as much concern for tornadoes). Even so,
strong winds aloft over Arkansas created a fast storm movement...with spotty
wind damage mainly in the southern and eastern counties.
In the picture: Widespread showers and
thunderstorms pushed to the east across Arkansas with a front on 09/23/2006.
Damage Survey Information
A weak (F1) tornado was spawned from near Franklin to near Myron (both in Izard County). Another weak (F1) tornado was mostly in Sharp County, with
damage to at least a dozen homes about 5 miles south of Ash Flat (Sharp County). The tornadoes occurred on September 22nd.
