Las Vegas to Memphis Turbulence Forecast

LAS → MEM · 1,413 miles · ~3h 20m

What to Expect

The Las Vegas to Memphis route can present a variety of turbulence types, given the diverse geography it crosses. Departing Las Vegas (LAS), you'll first encounter the Mojave and Sonoran Deserts, where thermal turbulence, caused by rising warm air, is common. As you head east, you'll cross the Southern Rockies, where mountain wave turbulence, caused by wind flowing over the mountains, might be felt. Further along, over the Great Plains, expect possible clear-air turbulence (CAT), which can occur even in seemingly clear skies. Tornado Alley and the Ozark Plateau introduce the risk of severe convective turbulence or just convective turbulence, caused by thunderstorms and unstable air. Finally, the Mississippi Valley and the Southeast Interior may also have convective turbulence. Pilots are trained to anticipate and navigate these conditions, using weather data to choose the smoothest possible path.

The Las Vegas to Memphis 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

• Thermal Turbulence: Extreme desert heating generates strong thermal updrafts that cause low-to-mid-level turbulence, especially in summer afternoons.
• Mountain Wave Turbulence: The Southern Rockies produce lee waves when southwesterly upper-level winds flow across the terrain.
• Clear-Air Turbulence (CAT): The jet stream frequently meanders over the Great Plains, producing wind shear and clear-air turbulence at cruising altitudes.
• Severe Convective Turbulence: Tornado Alley supercells produce some of the most intense convective turbulence in North American aviation.

When Is This Route Bumpiest?

The winter and late fall months tend to offer the smoothest flights from Las Vegas to Memphis. The air is generally more stable during these times, reducing thermal and convective activity. Summer, late winter, spring, early spring, and early summer tend to be the bumpiest seasons on this route. The warmer temperatures in summer increase thermal turbulence over the deserts and convective turbulence in the Plains and Southeast, while late winter, spring, early spring, and early summer bring the risk of stronger weather systems, potentially leading to more turbulence.

Tips for This Flight

If you're anxious about turbulence, consider booking your flight for the morning, as the air is often calmer then. Turbulence on this route will probably feel like driving on a bumpy, unpaved road, with some moderate shaking. Remember that the pilots are constantly monitoring conditions and have the experience to handle it. For extra comfort, choose a seat over the wing, as this area experiences less motion, and remember to stay hydrated and focus on deep, steady breathing. You've got this, and the flight crew is there to help you have a safe and comfortable journey.
