Initial watch for the area....

The storm reports.....

Big bulls-eye over northeast Illinois
NOTE: I have added models and warning texts just to give you a timelime of the events that occurred prior to, during, and after the intercept of this historical event.Adam Lucio and I were talking from about 4 PM until we both left at around 530 PM. You can read our convo on his
blog page. After he set off, I quickly followed. I grabbed my radio and my camera and ran out the door. As I left my NWR was replaying this message.....

THISSTORM IS CAPABLE OF PRODUCING STRONG TO VIOLENT TORNADOES. IF YOU AREIN THE PATH OF THIS TORNADO...TAKE COVER IMMEDIATELY!After driving south along Pulaski road, I encountered moderate rain from other nearby garbage cells. As I was stopped at the light at 159th Street, Markham and Oak Forests tornado sirens fired up as a very dark horizon approached from the south and west.

Driving south on Interstate 57 in the core of the supercell storm which is producing a large destructive tornado that is currently crossing the highway right in front of me.

Interesting to note that people are parked underneath the over pass at Lincoln Highway (Route 30) Heavy rain and small hail are falling at this time.

Looking east at the edge of the meso as the large multi-vortex tornado is just off to the right of this picture.

Looking straight up at the huge meso, kind of reminiscent of the Red Rock, Oklahoma tornado back in 1991

Radar at the exact time most of the pictures were taken. Notice the tell-tale classic supercell structure as it moves ENE into the South side of Chicago

I was nearing the end of the precipitation core and could finally make out the large bowl shaped wall cloud through the rain.... I quickly realized that the trees would reveal something much bigger.

Finally broke through the core, to the sight of a large violent tornado as it is tearing through Park Forest, Illinois. Looking southeast at I 57 and Sauk Trail Road.

Multiple vortex tornado just east of the interstate.

Multi-vortex tornado kept forming into hybrid wedge as it was traveling NE through Richton Park. * Note it was not a wedge tornado, this tornado fluctuated from large bowl with multiple vorticity into slender stove pipe before going back into multiple vortex.

Got off at Sauk Trail Road, heading east as tornado was still on the ground. I didn't know what to expect as I saw fire trucks and ambulances screaming toward the East.
...A TORNADO WARNING REMAINS IN EFFECT UNTIL 715 PM CDT FOR EASTERNWILL AND SOUTHEASTERN COOK COUNTIES...AT 620 PM CDT...EMERGENCY MANAGEMENT REPORTED A LARGE TORNADO ON THEGROUND NEAR RICHTON PARK. THIS TORNADO WAS MOVING NORTHEAST AT 29MPH.Was the last warning I cared about as I lost sight of the tornado and had no desire to fight traffic and damage to chase it deeper into residential area.

With the incredibly violent look of the tornado, it THANKFULLY didn't produce the massive damage like myself and many others thought it might have.

Radar image at the time I broke off the chase through Richton Park.

I continued to the east for about a mile before I had to stop because of damage to a car wash and apartment complex. I had to continue east and head south on Chicago Ave. Where I encountered tree damage and.....

Property damage. The main tornado lifted moments later just NE of Governors Highway as I encountered damage from another brief tornado that touched down in Chicago Heights.

Property damage above was from this tornado.

Very interesting here.... The main tornado is further off to the left in this picture. I may have caught tornado number 7 that this storm produced just to the right of the first power pole. The storm cycled so many times in such rapid fashion that there was no telling when or where another would drop. I firmly believe I caught tornado #2 for me that day as reviewing the road I was on and the location of that feature was very very similar.

RECAP/THOUGHTS: This was a gamble today. To stay in IL or go to IA. IA was the RIGHT decision this day, but I am a gambling man and knew I couldn't miss an event so close to home. Nothing was guaranteed on this day. I could have easily busted playing the Northern to Northeast Illinois target. I firmly believe if the Quinter,KS days didn't happen that these tornadoes in Northern Illinois would have been tops for tornado of the year.
On a more un-selfish note. I want to give MAJOR props to the National Weather Service in Chicago for their timely warnings and continuous coverage of this event. Only 2 non-serious injuries were reported with any of these tornadoes which at their strongest were only EF-2's. I commend their efforts and the efforts of the storm spotters giving live ACCURATE reports from the first tornado near O'dell til the 8th tornado in Lansing lifted. Great job all around.
