What Storm Chasing Actually Is (and Isn't)
Storm chasing has captured the public imagination through documentaries and Hollywood films, but the reality is far more methodical than the action sequences suggest. At its core, storm chasing involves strategically positioning yourself to observe severe weather — typically supercell thunderstorms and tornadoes — from a relatively safe vantage point. The keyword is strategically.
Reckless thrill-seeking near tornadoes is dangerous and foolish. Informed, prepared, disciplined observation is something else entirely — and it has contributed real scientific data that has improved public warnings over the decades.
Essential Knowledge Before You Chase
No one should attempt storm chasing without a solid foundation in meteorology and severe weather dynamics. At a minimum, you should understand:
- How supercell thunderstorms form — particularly the role of wind shear, CAPE (Convective Available Potential Energy), and storm-relative helicity
- Storm structure — being able to identify the forward flank, rear flank downdraft, wall cloud, and mesocyclone visually
- Reading radar — interpreting NEXRAD Doppler radar data, including velocity scans that reveal rotation
- Synoptic weather maps — understanding how surface boundaries, drylines, and upper-level features set up severe weather days
- Tornado types and behavior — knowing the difference between a rope tornado and a wedge, and understanding how tornadoes move
Quality free resources include NOAA's Storm Prediction Center educational materials, Comet MetEd online courses, and the National Weather Service's skywatcher training program.
Core Equipment for a Chase Vehicle
- Reliable vehicle with good visibility — sedans and SUVs work; avoid vehicles too tall to park under overpasses safely
- Laptop or tablet with mobile data — for accessing live radar, surface observations, and model data in the field
- Dedicated radar app — RadarScope is the industry standard among serious chasers
- GPS and mapping software — offline maps are essential when data service drops in rural areas
- NOAA Weather Radio — for official tornado warnings when you're out of data range
- Video or photography gear — optional, but documentation has scientific and personal value
- Emergency supplies — first aid kit, water, jumper cables, rain gear, and a hand-crank flashlight
The Chase Day Framework
Morning: Target Selection
Experienced chasers begin their day by analyzing weather model output, the SPC's convective outlook, upper-air soundings, and surface analysis. The goal is identifying a target area — typically a region where the atmospheric ingredients for supercells are best aligned — and calculating where to position yourself ahead of anticipated storm development.
Afternoon: Intercept
As storms fire, chasers update their radar view continuously. The goal is to approach a storm from the south or southeast — the typically clear, inflow side — while avoiding the rain-wrapped northern and northeastern sectors where visibility is poor and danger is higher.
Escape Routes: Non-Negotiable
Before getting close to any storm, identify at least two escape routes. Tornadoes can change direction. Roads in Tornado Alley are often laid out in a grid, but bridges wash out, roads flood, and debris blocks paths. Never position yourself north of a tornado or in a location with only one exit option.
Safety Rules That Experienced Chasers Never Break
- Never shelter under an overpass — this is one of the most dangerous places to be during a tornado
- Never chase at night unless you are highly experienced and have exceptional tools
- Always have a bailout plan before you need it
- Never chase alone if you're a beginner — go with a mentor or join a structured tour
- Respect other chasers and emergency vehicles on the road — congestion near tornadoes has become a real hazard
Getting Started the Right Way
The best path into storm chasing for most beginners is to join a guided storm chase tour operated by experienced meteorologists. These tours run through the Great Plains during peak season (late April through June) and put you in the field with professionals who handle all the meteorological analysis and driving decisions. It's a safe, educational way to experience severe weather and assess whether chasing is right for you before investing in your own setup.
