On august 9th, 2021, storm chasers would converge in northern illinois as a notable tornado threat would begin to materialize. A unique feature known as a mesoscale convective vortex, or MCV for short, would become the focal point of significant instability and wind shear. The target was obvious but the outcome was anyone’s guess. This is the Illinois tornado outbreak of 2021.
On a late summer afternoon in northern illinois, the storm prediction center issued a discussion stating that a tornado watch is possible. Once we were in position, things didn’t look promising as the initial storms were unorganized. However, additional development was expected later.
By 2:40pm, a tornado watch was issued which included the city of Chicago entirely. Millions of people are under the gun.
Eventually a supercell took shape and the chase was on!
Our first storm quickly lost our interest as an isolated cell directly to the south was beginning to rapidly strengthen. A new wall cloud formed and this would be the first six tornadoes we would witness today.
Although unplanned, James and I managed to be within a few miles of each other almost the entire day. Throughout this video, you will see two different perspectives of the same tornadoes.
The storm quickly recycled and formed a new funnel cloud as the updraft occluded, or wrapped around itself. Tornado #2 forms into a tall needle as it craws over open country.
Once again, the supercell cycled and this time a large and strong wall cloud took shape. This would go on to produce the Burlington tornado which we did not see due to rain obscuring it from behind. This was one of the more damaging tornadoes of the day.
The first tornado was rated an EF-0 with peak winds at only 60mph. While the funnel persisted for several minutes, ground contact was very brief.
The second tornado was rated EF-1 with peak winds at 90mph. This was on the ground for most of its life but only travelled 2.2mi as storms were moving quite slow.
The Burlington tornado was rated EF-1 due to the damaged house shown earlier. So far, nobody was hurt or killed . While the worst is yet to come, thankfully that number stays at zero at the end of the day.
While attempting to pursue the Burlington tornado, a new supercell exploded by Creston and immediately dropped a photogenic tornado. James and I scrambled to position for the next cycle. What happened next ended up being our best tornado intercept of the year.
The sycamore tornado would be the most notable of the day rated at EF1 with peak wind speeds at 105mph. The storm would go on to cycle an additional 3 times.
This EF-0 tornado was very brief and simply a precise to our final tornado of the day. This last tornado struggled to fully condense, but would grow to about a quarter of a mile wide. It was at that point that I basically drove into the tornado.
The last notable tornado of our chase was rated EF-0 at 85mph and grew to 400yds wide where it was a carousel of multiple suction vortices. Here you can see my location at the moment I stopped next to the tornado. Even weak tornadoes can still be quite intense.
The storm then moved into the suburbs of Chicago where it continued to show signs of producing a tornado. Fortunately, it met stable air and would fail to produce any damage in the metro area. Chicago dodger a bullet once more…
