Synopsis | Radar | Damage Survey Info | Storm Reports | Service | Other Recaps
A long-lived complex of wind producing storms known as a derecho moved across central and eastern Iowa, northern Illinois, and northern Indiana on June 24th. This lasted over 250 miles (and over six hours) and had a consistent swath of severe winds (58+ mph), qualifying it as a derecho. The initial driving force behind this complex was a subtle low pressure at around 15,000 ft in the atmosphere, and a sharp increase in westerly wind speeds at that level. This helped trigger the first storms along a surface stationary front. Robust instability from moisture and warmth built ahead of the initial storms in Iowa during the afternoon to help fuel them, as well as enhance the low-level wind threat. As the storms congealed and became more organized the atmosphere was favorable for them to drive themselves, and basically create their own local environment. That is they created a large cold pool of rain-cooled air under the storms, and this dense cooler air propagated with the storms aiding the strong winds. There were further enhanced by a classic rear-inlow jet, which basically helped those stronger winds at 10-15,000 ft mentioned earlier to work their way near the surface.

Below is a radar loop of the MCS through the area. The radar signatures are all ideal for strong winds, especially along and near the apex of the bow. The reflectivity gradient at the front is very sharp and quickly moving, all indicative of strong winds and sustainability. Note also little "hooks" on the front edge indicative of meso-vorticies, where brief tornadoes or at least enhanced winds were more favored. On the back side of the complex, you'll note a backwards "C-shaped" drying of reflectivity, indicative of a rear-inflow jet, a feature that can enhance the low-level winds and help sustain them for a longer period of time.

This graphic is dervied from the Doppler radar indicated rotation. Note the two long-lived rotation areas from south of the Quad Cities across north central Illinois. These rotational areas were rarely very strong, and were not in the most favored environments for tornadoes. Where these increased in intensity (pinks and white colors) is where there existed greater concern for possible tornadoes. |
...LEE COUNTY ILLINOIS DAMAGE SURVEY RESULTS...
NATIONAL WEATHER SERVICE PERSONNEL SURVEYED DAMAGE FROM THE STORMS
ON JUNE 24TH IN WESTERN AND CENTRAL LEE COUNTY IN NORTHERN ILLINOIS.
CONCENTRATED HIGHER END STRAIGHT-LINE WIND DAMAGE OCCURRED IN A
SWATH ACROSS THIS AREA...ALONG WITH A BRIEF TORNADO TO THE IMMEDIATE
NORTH OF THAT AREA.
LOOKING FIRST AT THE TORNADO:
* MAXIMUM EF-SCALE RATING: EF-0
* FATALITIES: NONE
* INJURIES: NONE
* BEGIN TIME/LOCATION: 06/24/2013...432 PM CDT /ESTIMATED/
2S OF HARMON IL
LAT 41.6995 LONG -89.5562
* END TIME/LOCATION: 06/24/2013...436 PM CDT /ESTIMATED/
2.5 ENE OF HARMON IL
LAT 41.7261 LONG -89.5154
* MAXIMUM ESTIMATED WIND SPEED: 85 MPH
* PATH LENGTH: 4 MILES
* MAXIMUM PATH WIDTH: 100 YARDS
* DISCUSSION/DAMAGE:
THIS PATH WAS MAINLY OVER FARM FIELDS BUT DID TAKE DOWN NUMEROUS
UTILITY POLES...INCLUDING A FEW THAT WERE BENT SHARPLY TO THE
SOUTH...OPPOSITE OF THE STORM MOTION WHICH WAS NORTHEAST. THESE
ALIGNED WITH THE NORTH PART OF THE DAMAGE SWATH. ONE WEAKLY
CONSTRUCTED BARN WAS DESTROYED NEAR THE END OF THIS PATH. DAMAGE TO
THE CORN CANOPY AT CROSSROADS ALONG THIS PATH REVEALED A MORE
CONVERGENT SIGNATURE INDICATIVE OF A SHORT-LIVED TORNADO.
LOOKING NOW AT THE CONCENTRATED STRAIGHT-LINE WINDS:
* EVENT: STRAIGHT-LINE WINDS
* FATALITIES: NONE
* INJURIES: NONE
* BEGIN TIME/LOCATION: 06/24/2013...429 PM CDT /ESTIMATED/
7SW OF WALTON IL
LAT 41.6690 LONG -89.5390
* END TIME/LOCATION: 06/24/2013...440 PM CDT /ESTIMATED/
1NNW OF AMBOY IL
LAT 41.7240 LONG -89.3359
* MAXIMUM ESTIMATED WIND SPEED: 100 MPH
* LENGTH OF WIND SWATH: ROUGHLY 13 MILES
* DISCUSSION/DAMAGE:
THROUGHOUT THIS SWATH INDICATIONS WERE THAT WIND GUSTS WERE IN
EXCESS OF 60 MPH WITH MULTIPLE LOCATIONS OBSERVING SPEEDS IN EXCESS
OF 80 MPH. AT TIMES DAMAGE WAS SOMEWHAT SPORADIC AND IN ZIG-ZAG TYPE
ORIENTATION...BUT OVERALL THIS WAS A SEMI-CONTINUOUS CORRIDOR ABOUT
ONE TO ONE AND A HALF MILES IN WIDTH. DEBRIS AND FALLEN TREE
PLACEMENT TO THE NORTHEAST...ALL CORN FLATTENING OR BENDING TO THE
NORTHEAST...AND MOST EYE-WITNESS REPORTS INDICATE THIS WAS FROM
STRAIGHT-LINE WINDS.
NEAR THE BEGINNING OF THIS ENHANCED WIND AREA...A LARGE OUTBUILDING
WHICH WAS BOLTED TO ITS FOUNDATION WAS DESTROYED WITH SEVERAL LARGE
PIECES BEING LIFTED AND THROWN DOWNSTREAM. ONE PART OF THE BARN WALL
WAS LIFTED UP AND TOOK A PIECE OF THE FOUNDATION WITH IT. SLIGHTLY
DOWNSTREAM A LARGE TREE WAS SNAPPED NEAR ITS BASE AT A PROPERTY WITH
THE TREE FALLING ON THE FRONT PORTION OF THE HOUSE. IN WALTON...FOUR
LARGE GRAIN STORAGE BINS WERE DESTROYED ALONG WITH A METAL
OUTBUILDING. THE DEBRIS FROM THIS WAS FLUNG DOWNSTREAM...INCLUDING A
FEW PIECES BEING IMPALED IN THE REMAINING STANDING PART OF THE
ELEVATOR WHICH WAS ON THE EAST MOST SIDE OF THE PROPERTY. TWO OF
THE BINS WERE BASICALLY FOLDED IN ON EACH OTHER. NEAR THE END OF
THIS SWATH...THERE WERE A HANDFUL OF LARGE TREES SNAPPED WITH
NUMEROUS UPROOTED.
ADDITIONAL INFORMATION ON THE WIND DAMAGE IN THIS AREA WILL BE
PROVIDED AS IT BECOMES AVAILABLE.
THE NATIONAL WEATHER SERVICE WOULD LIKE TO THANK LEE COUNTY
EMERGENCY MANAGEMENT...AMBOY ESDA...AND ROCKFORD MEDIA PARTNERS WHO
ASSISTED WITH PHOTOS AND DETAILED REPORTS OF THE DAMAGE IN ADVANCE.
THIS PRELIMINARY INFORMATION WAS DETERMINED BY NATIONAL WEATHER
SERVICE SURVEY TEAMS AND IS SUBJECT TO CHANGE PENDING FINAL REVIEW
OF THE EVENT AND PUBLICATION IN NATIONAL WEATHER SERVICE STORM DATA.
THIS INFORMATION WILL ALSO BE PROVIDED ON OUR WEBSITE AT
WWW.WEATHER.GOV/CHICAGO. MORE INFORMATION MAY BECOME AVAILABLE AT A
LATER DATE.
FOR REFERENCE...THE ENHANCED FUJITA SCALE CLASSIFIES TORNADOES
INTO THE FOLLOWING CATEGORIES:
EF0...WIND SPEEDS 65 TO 85 MPH
EF1...WIND SPEEDS 86 TO 110 MPH
EF2...WIND SPEEDS 111 TO 135 MPH
EF3...WIND SPEEDS 136 TO 165 MPH
EF4...WIND SPEEDS 166 TO 200 MPH
EF5...WIND SPEEDS GREATER THAN 200 MPH
