How Tornadoes Form and Why It Matters
A few weeks ago, I came across a post from a local weather enthusiast that made me pause: 24 tornadoes in Wisconsin in just one week. Our yearly average is 23 and we reached that in about five days. That’s not just a statistic…that’s a signal. It made me wonder what the rest of the season might hold.
Living in Wisconsin, we’re no strangers to unpredictable weather, but numbers like this have a way of drawing attention. It’s a reminder that nature doesn’t always follow the calendar, and sometimes we need to be just a little more aware, a little more prepared, and a little more respectful of what’s happening.
At the same time, there’s something quietly fascinating about it all...the power, the science, the way the atmosphere can shift so quickly. It’s not about fear, but awareness. When we understand what’s happening, we’re better equipped to respond calmly and wisely if needed.
How do
tornadoes form?
Tornadoes typically develop from severe thunderstorms, especially a type called a supercell. Inside these storms, warm, moist air rises quickly while cooler air sinks. When wind speeds and directions change at different heights (called wind shear), it can cause the air to start rotating horizontally. That rotating air can then tilt vertically and tighten into a spinning column,
eventually forming a tornado if it reaches the ground.
What can they produce?
Tornadoes rarely come alone. The storms that create them can bring:
Damaging winds (sometimes over 100–200 mph in stronger tornadoes)
Large hail that can damage roofs, cars, and crops
Heavy rain and flash flooding
Frequent lightning
Flying debris, which is often the most dangerous part
Why take them seriously?
Because they can form quickly and change direction without much warning. Even smaller tornadoes can
cause significant damage. Taking them seriously doesn’t mean panicking. It means being prepared. Knowing where to go (a basement or interior room), keeping alerts on your phone, and paying attention to weather updates can make all the difference.
We can’t control the weather, but we can control how we respond to it. Stay
aware, have a simple plan in place, and then go about your day with confidence. Here are a few extra tips...
1. Know the Difference: Watch vs. Warning
A tornado watch means conditions are right for tornadoes to form. This is your heads-up to stay alert and maybe adjust your plans. A tornado warning means a tornado has been spotted or indicated on radar. That’s your cue to take shelter right away.
2. Rethink Errands During a
Watch
If a tornado watch is in place, it might not be the best time to run to the grocery store or head out for non-essential errands. Staying close to home (or a safe location) gives you more control if conditions worsen quickly.
3. Have a Go-To Safe Spot
Whether you’re at home or work, know exactly where you’d go if a warning is issued. A storm shelter or basement is best, but if that’s not available, choose an interior room away from windows, like a bathroom, closet, or hallway.
4. Protect Your Vehicle When You Can
If you’re at work and severe weather is expected, try to park near a building (on the side away from the wind, if possible) or under a covered area. If hail is a concern, heavy rubber floor mats placed over the windshield (if time allows) can help reduce
damage.
5. Keep Alerts Turned On
Make sure emergency alerts are enabled on your phone or consider a weather app or NOAA weather radio. Storms can develop quickly, and a timely alert can give you those extra
minutes that matter.
