The perfect storm: Forecasters look back on the origins of the May 8 derecho

Even Corfidi could not predict the magnitude of the destruction he would see the following day, as those clouds traveled 1,000 miles to unleash an inland hurricane on

In the springtime, jet streams typically rush across the Midwest at high rates of speed, pulling warm air from the south towards cooler air in the north at every point along the way.
At points where there are particularly strong contrasts between warm and cool air, with great disparities in temperature or moisture content, storms are born. In other cases, existing storms are grabbed and carried along in a jet stream's flow.
"Jet streams move constantly and our day-to-day weather is a manifestation of their presence and changes in them," Corfidi explained. "In the springtime, the Midwest hosts a jet stream that wiggles from day to day and week to week, but whose mean position is right along
Pinwheeling along that jet stream, the storm began to self-accelerate. Falling rain created a bank of cool air at its leading edge. As the storm moved east through
That warm air released new moisture into the clouds, producing new rain to fuel the storm's cold-air motor.
"There's a lot of factors that go into how a thunderstorm complex organizes, but the thing that separates them is the wind profiles, as you go up through the atmosphere," explained

"A storm is nature trying to reach equilibrium. If it's too warm at the surface and too cold aloft, it makes the air want to overturn," Corfidi explained. "That low-level jet stream gave it lots more fuel to release."
The storm continued to grow, beginning to take the wide, bowed shape that characterizes a derecho, what meteorologists call a "bow echo."
Eighty mph winds hit Eureka and Buxton,

"It began to develop this circulation," Corfidi said, as an area of low pressure pulled in warmer air from all sides. "You can almost see an eye on it, and it had a lot of spin to it. That's what people have since called an inland hurricane."
That ferocious, four-county-wide storm cell is what hit
Looking back, Corfidi sees an impressive confluence of "Goldilocks factors," that allowed the

"When storms become this big and intense for a long period of time it depends on many factors coming together just right," Coniglio said. "That's the difficulty of forecasting weather. Small changes somewhere can make a huge difference somewhere else."
Mother Nature's challenge
The day of the derecho was scary at best. With down trees, no power and damage to the house, it was clear we were being challenged by Mother Nature.
When a few of us were discussing the day recently, the contribution by River Radio was mentioned. Members of the River Radio staff also had affects of the storm to their property, but the staff showed up and kept the sound waves going. The radio station gave up-to-date reports of weather and where people could get food, shelter, water and hope.
The entire region was affected by these unselfish individuals who put the community needs above themselves. I will always be thankful to the

The amount of rain that came down is what I remember most. It felt like I had parked the car under a waterfall. Luckily, we were able to drive away when the storm ended, and then realizing we were could not get many places due to downed trees and lines.

A solid wall of water
We remember the super derecho! My husband had rotator cuff surgery the day before and we were at Southern Illinois Orthopedics for his therapy.
The first storms started rolling in and the medical and clerical staff rounded everyone up and put us in an interior room. After the storm passed, we left the ortho center and went to pick my sister up for lunch at Triple E BBQ just off of
While we were eating, another storm (the derecho) came roaring in. The ceiling tiles in the restaurant were blowing all over the place, the customers, including us, were standing at the windows watching trees and poles flying through the air. And the rain. Omg, the rain! It was a solid wall of water! It was scary as hell!
It didn't last long but it sure seemed like it did. We left as soon as it was safe. Tried taking my sister home (she lived on

More exciting than horrific
I was at the end of my sophomore year at SIUC, and everyone was packing up and moving out of the dorms for the summer. When the storm hit, I was in Kellogg Hall and even though a few people went to the basement, most of us just stood in the halls and watched trees fall over next to the lake. Someone yelled that a car got crushed out front. I remember calling my mom in the middle of it and excitedly narrating the storm. I think she was confused as to why I was calling her and not going downstairs.
After everything calmed down, I walked around and took pictures of the damage. The power was out, so I didn't have much light for packing the rest of my belongings to go home. And, not having anything better to do, a group of my friends got together and played Simpsons Clue by candlelight. Ultimately, I remember it more as an exciting experience than a horrific one, but then again, I didn't own property in the area.
The worst storm in my lifetime
I am 87+ years old, and the 2009 derecho was the worst storm I've experienced in my lifetime.

I drove home with a friend as passenger. We were horrified at seeing some huge, beautiful trees lying on the ground. I panicked when I saw some electrical wires lying across the road. I was hesitant to drive over them and waited until I saw another car do it safely.
Trees were blown down next to my home, but the dwelling was not touched. I was safe and felt the need to say a prayer of

However, lunch was cut short due to a rainstorm brewing from the west. As the dark clouds started rolling in, I received a phone call from one of my employees. She told me to be prepared because there was a funnel cloud spotted in
We had a number of guests in the restaurant and I came back to alert the people that were sitting near the windows to please move to the center of the restaurant. Everyone responded with the exception of a few who paid and left. A tree on the south side of Denny's flew through the air, electricity went off and a light pole fell just inches away from an employee's car. I instructed the remaining guests and employees to go into our storeroom. Everyone responded and thank good goodness our emergency lights came on.
After the storm was over, I noticed that big trees and lines were down in

I worked at as a customer service supervisor at Kroger at that time. I had only been clocked in a few moments when I received a call from upstairs management.

"Attention,
I began helping customers find the door to the cooler. The tiny room was crammed full of about 50 people. A woman with tears pouring down her cheeks refused to enter. "I can't handle this. I can't do this," she kept repeating. I didn't know what to do, instinctively I hugged her and begged her to go into the room to be safe. Another woman took her arm and told her to keep breathing and keep her eyes closed.
I heard the walls creaking from the wind and watched as the suspended aisle signs bounced frantically on their cables. I'm not religious, but I prayed, "Please, God, not here, not today, I'm meant for more."
The power didn't go off until after the storm. I spent the afternoon helping to preserve as much of the cold merchandise as possible. Because we were going to lose it anyway, management rolled out grill and began cooking up food for the crew and customers who wandered over in search of supplies and answers.
I walked home that night, across the town I'd lived my entire life, and for the first time ever I didn't know where I was. The city was unrecognizable.

After the storm, I remember seeing a field of tree limbs. We thought that our mobile home was destroyed, but with god's grace, it wasn't. We walked through a flight of 30 steps covered with tree limbs to get back inside. A day I certainly won't forget.

We had a lot of down time without power at our apartment complex and it allowed us all to get to know our neighbors better. We were forced to be creative with our food options as I remember watching my roommate cook eggs on the grill.
I remember watching the storm with my roommate and realizing it was unlike anything we had ever experienced.
A long journey home
At dawn on
When the rain and wind stopped, I walked in around fallen trunks and tree limbs past Pulliam and Shryock. The oldest part of campus' landscape looked destroyed. My destination was the physical plant offices where Dave worked. Our phones weren't working. He wasn't in his office.
The sun was now out and the sky was blue. I got our truck, but had trouble finding a route away from campus that was clear to drive through. I saw Dave driving an SIU vehicle at the

I used the chainsaw and tractor to begin clearing the driveway. It would take days. Dozens of trees were down along our fields' extensive woodlines, which wouldn't be totally cleared up for a couple years.
I reached our high school kids at friends' houses in town. They would stay where there were showers, they said. We had no electricity or running water. Dave didn't make it home that night either. He slept a few hours in a chair at work. He directed overtime crews for many days.
The kids drove home to help haul limbs to piles. We rummaged through the refrigerator and cupboards for perishable foods and crackers. I had drinking water stored. All day and evening, we could hear chainsaws through all the valleys all around our property.
Dave came home after dark with extra gas and a

It took me 90 minutes to drive from the bank six blocks to return the car having to navigate around all the downed trees. The rental folks left the hail damage to the insurance adjuster and they gave me a ride to the Amtrak station. It was surreal. All the lights were out but people were going in and out of PKs emerging with beers in their hands.
I had no idea how many hours I would be spending in PKs the next decade but was impressed by the apparent resilience of the business. No inland hurricane or power outage was going to shut them down. The train couldn't make it through the wreckage so we took a motor coach to
Community's love on display
I was only 8 years old when this storm hit, but I will never forget the impact it had.
That day, I was not at school like most kids my age, instead, I was at my grandfather's funeral,
I will never forget the feeling of my car lifting off the ground as I watched the men of my family hold down the tent that was about to fly away and take them with it.
Once the storm had passed, we decided that we couldn't go home. As many know, my family owns Southside Lumber and we just didn't think it would be right if we cleaned up our own houses without helping others who truly needed it. We opened the store for those in need of supplies, and we operated in the dark. Many who came in needed help, but most simply wanted to help us serve others.
I'll never forget feeling the love God has for us and that this community has for each other because of the
Adopting friends as family in the aftermath
Being a foreigner can be a little hard sometimes, but is something that a traveler agrees to face for the experiences of being immersed in another culture. Thus, in 2003 began the crusade of my life from
As a single mom of two young girls I started that day as always with the trip to leave them at a friend's house for childcare. Next, I went to SIUC to work, and at noon, I went back home for lunch. Suddenly, I still can feel in my skin the sensation, I heard the sirens, and I was shocked. The day became almost night and the wind was blowing everything. I could see nature in its highest expression, trees flying everywhere.
I was terrified thinking of my girls, far away, and I started driving to them. Finally, when I was four blocks away from the girls, the street was blocked. I climbed the trees on the street and finally I reached them. While I was climbing the trees, I started to think of my friends I made in those few months since arrived in
The first who came to my mind was Roy, I knew he was living in the forest, thus I called him ... Hi Roy, this is Laura. How are you? Are you OK? ... And he was calm and replied ... Laura, I am OK but my house is wrecked. I started to cry, and I told him, you can stay at our house if you need. He did it. We adopted Roy as part of our family and now in

The day our woods changed forever
My wife and I live in
It was about
As the storm increased in intensity, we'd scamper out into other parts of the house to see the unreal scene developing only to retreat to our safe place when another huge limb or tree came thundering down. It took about 15 minutes of winds around 80 mph with gusts over 100 mph to make an indelible change to our wooded environment. We struggled to get out our debris-covered front and back doors.
The damage was surreal. Huge trees were uprooted, and devastation was everywhere. Using a chainsaw, it took over three hours to clear 750 feet of driveway only to discover the main road impassable. Fortunately, our home incurred little damage, but a nearby outbuilding was destroyed by a fallen oak of large proportion.
Our woods will never be the same. The thick tree canopy is mostly gone as the debris and now the thick undergrowth make access to our woods difficult still. Even though it changed our woods forever, we're thankful we survived.
Making friends in face of chaos
I was working in Best Buy when the storm hit.
It took me almost an hour to drive across town through downed trees and power lines. My roommate and I spent the next few days grilling every bit of food we had in the freezer and sharing it with the neighbors. I met more people in my neighborhood the week the power was out than the other two years I lived in that house.
I made several good friends during recovery.
Happily ever after
It was exactly one week before my high school graduation from
Going out into the hallway to sit, we were instructed to stay away from windows. I remember being able to hear the wind howling, rain pouring, thunder booming, and girls screaming with fright. No one knew exactly what was going on, but we knew that it had to have been something serious.
After the winds had finally calmed down, the school immediately called the buses to take us home. What would normally be about a 30-minute bus ride home took over an hour and a half. The buses had to take alternate routes to get us home because certain roads were flooded or blocked off by trees or powerlines. At one point, the bus driver told us he couldn't drive any further and had to just let us off the bus where we were at and walk home from there.
Looking back, I was OK with that because I was in high school, but I wonder what they did for the elementary kids? Anyway, school lets out around
In front of my house, there was a tree that was leaning toward our roof. It is no longer there anymore because my family had it cut down due to the storm. I remember lighting candles and using flashlights because no one had power. Also taking cold showers because the hot water heater didn't work.
Now with this tragedy happening and putting everyone in a frenzy, you would think emotions would be at an all-time high. However, everyone in the community was so nice to one another because we were all enduring this struggle together. I remember lots of people barbecuing because they had to cook all their meat before it spoiled. My grandmother's neighborhood was one of the first to receive power, so my family of course went to spend a couple nights at her house. Then as power began to come back to the rest of the city, more people starting coming out their houses.
