Today marks the 4 year anniversary of the devastating EF-4 tornado that ripped through the areas of Rochelle, Fairdale, etc…


The 2015 Rochelle–Fairdale, Illinois tornado was an extremely violent and long-lived tornado that tore through the communities near Rochelle and in Fairdale, Illinois throughout the evening hours of April 9, 2015.

Part of a larger severe weather event that impacted the Central United States, the tornado first touched down in Lee County at 6:39 p.m. CDT (22:39 UTC). It progressed through the counties of OgleDeKalb, and Boone before finally dissipating at 7:20 p.m. CDT.

Along the tornado’s 30.14 mi (48.51 km) path, numerous structures were heavily damaged or destroyed, especially in the small town of Fairdale where two fatalities and eleven injuries were recorded.

A few well-constructed homes were swept completely away, indicative of peak winds near 200 mph (320 km/h), the upper bounds of an EF4 tornado.

In the aftermath of the event, hundreds of citizens assisted in cleanup and recovery efforts. Economic losses from the tornado reached $19 million (2015 USD).


The strongest tornado in the United States during 2015 first began at 6:39 p.m. CDT (23:39 UTC) on April 9, just northeast of Franklin Grove, Illinois. It touched down over a field, producing swirls in crops, before moving northeast and causing EF1 damage to the Crest Foods plant.

The tornado soon exited Lee County and entered Ogle County, inflicting EF1 damage to two farm outbuildings that were completely destroyed and EF0 damage to a similar structure that had a portion of its roof uplifted.

Intensifying to EF3 strength, much more severe damage was noted along South Skare Court as the tornado entered an area of semi-rural subdivisions to the northwest of Rochelle.

A few homes in this area were destroyed at EF3 intensity, with other homes nearby sustaining EF2 damage. One large house had a room ripped off on its second floor, while a split-level home was almost completely leveled.[13]

As the tornado crossed South Richard Road, it intensified to very high-end EF4 strength and inflicted catastrophic damage to several large homes as it impacted the Deer Creek subdivision.

Well-built homes along South Richard Road and East Kuehl Court were leveled and swept from their foundations with debris strewn downwind. Several vehicles parked at these residences were moved some distance or tossed, and wind rowing of debris occurred.

One house had its concrete walkway pulled a few inches from its original location, and notable scouring of lawn grass was observed in the subdivision. These structures were estimated to have been impacted by winds near 200 mph (320 km/h), the upper bound of an EF4 tornado.

The homes swept away in this area were bolted to their foundations and there is some speculation that the tornado may have reached EF5 intensity at this point, though close inspection revealed that some of the washers were missing from the anchor bolts, and that low-lying shrubbery near the homes was left mostly intact, preventing a higher rating.

Continuing northeast, the tornado temporarily weakened, producing EF2 to EF3 damage as it destroyed a few large barns or outbuildings, ripped the roof off two brick residences, and collapsed most walls of another house, but once again gained strength as it approached and crossed Illinois Route 64. A large restaurant and a residence had their exterior walls collapsed in this area.[13]

Very high-end EF4 damage was again observed near the intersection of Illinois Route 64 and Illinois Route 251, where a row of five homes was completely leveled, two of which were swept away.

Anchor bolts were again present at these residences, though the foundations were of cinder-block construction. Intense ground scouring was evident nearby, a car was thrown a full mile, and debris was wind-rowed long distances through fields in this area.

Winds were again estimated at around 200 mph (320 km/h), with the damage at this location again being near-EF5 in intensity. Further to the northeast, the tornado inflicted high-end EF4 damage as a large farmstead was completely destroyed.

A well-constructed barn was completely obliterated, and a 40 ft (12 m) reinforced concrete silo was reduced to a pile of rubble. A large farmhouse on the property was completely swept away, and nearby trees were severely stripped and debarked.

The tornado weakened as it crossed North Moore Road, where a warehouse building had a collapse of its non-bearing exterior walls. One small barn or outbuilding had a collapse of exterior walls while another had a few metal roof panels ripped off. After crossing Interstate 39, it caused moderate roof damage to a large residence and tossed and rolled a heavy barn.

The tornado continued to produce generally EF1 damage to trees and outbuildings before exiting Ogle County, and it was briefly accompanied by an EF0 satellite tornado that damaged crops to its southeast.[13]

After entering DeKalb County, the large tornado directly impacted the small community of Fairdale.

Approximately 71 homes sustained some degree of damage, including 13 that were destroyed. Several houses on the northwest side of town sustained damage consistent with an upper-end EF3 tornado, with all walls collapsed. A few houses that were nailed to the foundation—not bolted—were swept clean.

A 67-year-old woman and her 69-year-old neighbor were both killed in their homes, and an additional 11 people were injured throughout the town.

Continuing northeast across Wheeler Road, one residence had a large portion of its roof ripped off, a second residence had its exterior walls collapsed, and a two-story 80-year-old well-constructed barn was destroyed.

A large garage was destroyed and had its debris deposited well downstream, and significant denuding and debarking of trees was evident. Near the intersection of Irene Road and McNeal Road, a well-built seven-year-old house lost its second story and many exterior walls.

A two-story well-built barn with cinder block attachment was totally destroyed, and a nearby two-story rebar-reinforced cinder block silo was ripped apart.

Large farm equipment was tossed 0.25–0.5 mi (0.40–0.80 km), and convergent scouring of road pavement was noted in this area.

After passing over rural terrain, the tornado finally dissipated at 7:20 p.m. CDT (00:20 UTC) over Cherry Valley Road, ending its 30.14 mi (48.51 km) and 41-minute path of destruction.[13]


Fast Facts

  • Eleven tornadoes were confirmed across Illinois: seven in north central Illinois in the NWS Chicago County Warning Area (CWA), two in northwest Illinois in the NWS Quad Cities CWA, and two in central Illinois in the NWS Lincoln CWA.
  • Six of the tornadoes across north central Illinois formed from one supercell thunderstorm. This includes the strongest tornado that was a long track EF-4 with maximum winds of 200 mph. This tornado began from near Franklin Grove (Lee County), through the northwest side of Rochelle (Ogle County), across I-39, through Fairdale (DeKalb County), and ending south of Belvidere (far southern Boone County).  This tornado caused two fatalities, both in Fairdale, and a total of 22 injuries.
  • A tornado of this magnitude is quite rare. This was the first EF-4 or stronger tornado in the NWS Chicago County Warning Area in 25 years, since an F5 tornado struck Plainfield on August 28, 1990.   This was the strongest tornado on record (since 1950) for both Ogle and DeKalb Counties.
  • This was the first EF-4 tornado or stronger in Illinois since two EF-4 tornadoes occurred on November 17, 2013, including one that struck the community of Washington.  This was the 33rd EF-4 or stronger tornado in Illinois on record (since 1950).
  • The atmosphere was ripe for severe weather due to highly anomalous moisture and instability for early April across the region.  A strong low pressure system advanced into this favorable air mass. Combined with robust wind shear, this helped to trigger these potent storms.
  • The potential for severe weather was mentioned in NWS forecast graphics and products as early as Saturday, April 4th.

Rotation Tracks

 

The four panel radar images below display: radar reflectivity (top left), radar storm relative velocities from two different radars (top right and bottom right) and Correlation Coefficient (CC).  Storm relative velocity tells us if a storm has rotation. The green colors in the imagery represent winds blowing towards the radar, while the red colors indicate winds blowing away from the radar. Therefore, strong rotation can be inferred in the storms showing bright red colors directly adjacent to bright green colors in the storm relative velocity images.  This is also the area of the storm where the tornado is most likely to be occurring.   Reflectivity and storm relative velocity used together with CC data can indicate the presence of debris resulting from a tornado.  In basic terms CC is the correlation between the reflected horizontal and vertical power returns that the dual pol weather radar provides.  CC data tends to be near one with most precipitation type echoes.  Therefore, when the CC data is found to be very low (represented by the blue colors), it suggests that the radar is not sampling precipitation.

Notice that in the second radar four panel for the Franklin Grove to Margeno supercell time stamped 6:59 pm that a clear area of low CC data (Blue area) is identifiable within the radar reflective hook echo just north of Rochelle. This area also corresponds with the area of strong rotation as noticed in the storm relative velocity image in the top right. The Low CC in this area tells the radar operator that the strong reflectiveives within the hook echo in the top left panel is not precipitation, but is actually the radar seeing the debris being lofted from a tornado.

Meteorology

  • The atmosphere was ripe for severe weather due to highly anomalous moisture and instability for early April across the region.  A strong low pressure system advanced into this favorable air mass. Combined with robust wind shear, this helped to trigger these potent storms.

Surface Weather Map

 


Climatology

  • The peak tornado season in Illinois is April through June.
  • This was the first EF-4 tornado or stronger in Illinois since two EF-4 tornadoes occurred on November 17, 2013, including one that struck the community of Washington.  This was the 33rd EF-4 or stronger tornado in Illinois on record (since 1950).
  • This was the first EF-4 or stronger tornado in the NWS Chicago County Warning Area in 25 years, since an F5 tornado struck Plainfield on August 28, 1990.
  • This was the strongest tornado on record (since 1950) for Ogle County, where EF-4 damage was observed. The previous strongest tornado on record in Ogle County since 1950 was an F-3 on August 5, 1979.  The last tornado in Ogle County prior to April 9, 2015 was May 22, 2011, when three EF-1 tornadoes occurred.
  • This was the strongest tornado on record (since 1950) for DeKalb County, where EF-3 damage was observed. The previous strongest tornado on record in DeKalb County since 1950 was an F-2 on June 18, 1975.  The last tornado in DeKalb County prior to April 9, 2015 was an EF-0 on May 13, 2011.
