What to Expect

Your Greensboro to Phoenix flight is a bit like a cross-country road trip, weather-wise, with distinct ‘terrain.’ Initially, you'll cross the Southern Appalachians, where mechanical turbulence caused by wind interacting with mountains can create some chop. Next, over the Ohio and Mississippi Valleys, you might encounter frontal or convective turbulence, especially if there are weather systems moving through. As you enter the Ozark Plateau and Tornado Alley, convective turbulence could increase, particularly if it's a day with potential storm development. The Great Plains could bring clear-air turbulence (CAT), which, although unexpected, is routinely monitored by pilots. Approaching Phoenix, the Southern Rockies might cause mountain wave turbulence. Finally, thermal turbulence is possible over the Mojave and Sonoran Deserts as the land heats up. This route covers a wide range of common turbulence types, all of which pilots are trained to handle safely.

The Greensboro 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

• Mechanical Turbulence: The Southern Appalachians produce terrain-induced chop, especially during strong wind events and summer convection over the ridgeline.
• 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.

When Is This Route Bumpiest?

The fall months generally offer the smoothest flights on this route. The weather systems are less intense, minimizing frontal and convective turbulence. In contrast, winter, spring, and early summer tend to be bumpier. Winter brings stronger frontal systems across the Ohio and Mississippi Valleys, and spring and early summer can mean increased convective activity over the Ozark Plateau and Tornado Alley. Mountain wave turbulence is also more common near the Rockies in winter. Early spring and late winter can also be turbulent as weather patterns shift. Summer heat over the deserts can intensify thermal turbulence, too.

Tips for This Flight

If possible, aim for a morning flight; the atmosphere tends to be more stable then, especially over the deserts. Any turbulence you experience on this route will likely feel like driving on a slightly bumpy, unpaved road or encountering gentle waves on a boat. Bringing a refillable water bottle to stay hydrated can make a huge difference in how you feel throughout the flight, as can focusing on slow, deep breaths. Remember, the pilots are highly skilled at navigating these conditions, and your comfort and safety are their top priorities.
