Nashville to Phoenix Turbulence Forecast

BNA → PHX · 1,445 miles · ~3h 23m

What to Expect

Nashville to Phoenix is a westward journey across a diverse range of geographic features, each with its own potential for turbulence. Immediately after takeoff, you might encounter frontal turbulence over the Ohio Valley as you ascend. Then, flying over the Mississippi Valley and the Ozark Plateau, convective turbulence is possible, especially if it's a warm day. Tornado Alley brings the potential for severe convective turbulence. Further west, crossing the Great Plains, be prepared for clear-air turbulence, which can occur even in seemingly clear skies. As you approach Phoenix and fly over the Southern Rockies, expect the possibility of mountain wave turbulence. Finally, near your destination over the Mojave and Sonoran Deserts, thermal turbulence could cause some light chop. Remember, pilots are highly trained to navigate these conditions, and turbulence is a normal part of flying, not a sign of danger.

The Nashville 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 smoothest flights on the Nashville to Phoenix route are generally in the summer, early fall, and fall. These seasons tend to have more stable air masses, reducing the likelihood of convective turbulence and mountain wave effects. Winter, spring, early summer, early spring, late winter, and summer can be bumpier times to fly. This is due to increased frontal activity, convective thunderstorms, and stronger jet streams, all of which contribute to turbulence over the various geographic regions along the route.

Tips for This Flight

If possible, try to book your flight for earlier in the day, as morning flights often experience less thermal turbulence. Any turbulence you might experience on this route will likely feel like driving over a slightly bumpy road, or perhaps a more pronounced jolt similar to hitting a pothole. To enhance your comfort, choose a seat over the wing, where the ride tends to be a little smoother, and remember to stay hydrated by drinking plenty of water throughout your flight. Taking slow, deep breaths can also help calm your nerves. Rest assured that the flight crew is there to ensure your safety and comfort.
