What to Expect

Flying west from Pittsburgh to Phoenix, you'll cross a wide variety of geographic features that can contribute to turbulence. Departing Pittsburgh, you might encounter frontal turbulence over the Ohio Valley, where different air masses meet. As you continue west over the Mississippi Valley and Tornado Alley, convective turbulence becomes a possibility, especially if there are thunderstorms. Further along, over the Great Plains, clear-air turbulence, or CAT, can occur, which is often unexpected but usually not severe. Approaching Phoenix, you'll cross the Southern Rockies, where mountain wave turbulence can develop as air flows over the peaks. Finally, as you descend toward Phoenix, you might feel thermal turbulence created by rising warm air over the Mojave and Sonoran Deserts. Pilots are well-trained to anticipate and navigate these common weather patterns. They constantly monitor conditions and adjust altitude or course to find the smoothest ride possible.

The Pittsburgh to Phoenix route passes over the Southern Rockies in New Mexico and southern Colorado. While somewhat lower than the peaks to the north, these mountains still produce notable mountain wave turbulence, particularly when strong southwesterly winds aloft align perpendicular to the ridgeline.

Turbulence Factors on This Route

• Frontal Turbulence: The Ohio Valley is a preferred storm track where frontal boundaries and embedded convection create turbulence year-round.
• Convective Turbulence: The Mississippi Valley is a breeding ground for squall lines and mesoscale convective systems that produce widespread turbulence.
• Clear-Air Turbulence (CAT): The jet stream frequently meanders over the Great Plains, producing wind shear and clear-air turbulence at cruising altitudes.
• Mountain Wave Turbulence: The Southern Rockies produce lee waves when southwesterly upper-level winds flow across the terrain.

When Is This Route Bumpiest?

The calmest time to fly this route is usually from summer to fall, into early winter, when the air is more stable and thunderstorm activity is reduced. By contrast, late winter, early spring, spring, and early summer tend to be bumpier. The increased instability in the atmosphere during these months, especially over Tornado Alley and the Great Plains, can lead to more convective activity and stronger frontal systems, increasing the likelihood of turbulence. Mountain wave turbulence near the Rockies is also more common in the spring and winter months, due to stronger winds aloft.

Tips for This Flight

If you're concerned about turbulence, aim for a morning flight, which tends to be smoother before the day heats up and creates thermal updrafts, especially over the deserts. Any turbulence you experience on this route will likely feel like driving over a bumpy road or encountering strong wind gusts. Remember that pilots are always monitoring conditions and will take action to ensure your safety and comfort. To further ease your nerves, consider choosing a seat over the wing, which is closest to the plane's center of gravity, and practice deep, slow breathing to help you relax during the flight. You've got this.
