What to Expect

Your flight from Madison to Phoenix crosses a diverse range of landscapes, each with its own potential for turbulence. Shortly after takeoff, you might experience some light chop thanks to lake-effect turbulence forming off the Great Lakes. As you head west over the Upper Midwest and Great Plains, keep an eye out for clear-air turbulence, or CAT, which is caused by shifting air currents. Further along, you'll be over Tornado Alley, where severe convective turbulence is possible, especially if there are thunderstorms in the area. Approaching Phoenix, the Front Range and Southern Rockies can generate mountain wave turbulence as air flows over the peaks. Finally, thermal turbulence could arise over the hot Mojave and Sonoran Deserts. It's worth knowing that pilots are trained to anticipate and handle these conditions, using onboard radar and reports from other aircraft to navigate the smoothest possible path.

Flights between Madison and Phoenix pass along the Front Range, where the abrupt rise of the Colorado Rockies generates some of the strongest mountain wave turbulence in the continental U.S. Downdrafts east of the ridgeline can be intense, and rotor turbulence near the surface sometimes extends to cruising altitude during high-wind events.

Turbulence Factors on This Route

• Lake-Effect Turbulence: The Great Lakes produce lake-effect convection and low-level wind shear from land-water temperature contrasts.
• Clear-Air Turbulence (CAT): The Upper Midwest sits beneath frequent polar jet stream intrusions, producing clear-air turbulence at cruising altitudes.
• Mountain Wave Turbulence: Strong westerly winds over the Front Range create oscillating waves that can produce sustained moderate turbulence at jet cruise levels.
• Thermal Turbulence: Extreme desert heating generates strong thermal updrafts that cause low-to-mid-level turbulence, especially in summer afternoons.

When Is This Route Bumpiest?

For the smoothest possible flight on this route, aim for summer, early fall, or fall. These seasons generally see calmer atmospheric conditions over much of the route. In contrast, late fall, winter, early spring, and early summer tend to be bumpier. During these times, temperature contrasts can be more pronounced, leading to increased lake-effect turbulence, CAT, and convective activity in Tornado Alley. Winter also increases the chances of mountain wave turbulence near the Rockies.

Tips for This Flight

Choosing a morning flight is your best bet; the air is typically calmer before the day heats up, reducing thermal turbulence over the deserts and lessening the chance of afternoon thunderstorms. Any turbulence you do experience on this flight will likely feel like driving on a slightly bumpy road, or a boat gently rocking on the water. For added comfort, choose a seat over the wing; this tends to be the most stable part of the aircraft. Remember to stay hydrated, as this can help you feel more relaxed. With a little preparation, you can feel more at ease and in control during your journey.
