Little Rock to Las Vegas Turbulence Forecast

LIT → LAS · 1,292 miles · ~3h 5m

What to Expect

Your flight from Little Rock (LIT) to Las Vegas (LAS) will take you west over a variety of terrains, each with its own potential for turbulence. Initially, you'll be flying over the Ozark Plateau and then through Tornado Alley; this area is prone to convective turbulence, especially from spring into summer. As you continue west, crossing the Great Plains, you might encounter clear-air turbulence (CAT), which can occur even in cloudless skies due to shifting air currents. Further along the route are the Southern Rockies, where mountain wave turbulence is possible, caused by wind flowing over the peaks. Finally, as you approach Las Vegas, you'll cross the Mojave and Sonoran Deserts, where thermal turbulence can arise from the hot ground heating the air. Pilots are trained to anticipate and navigate these conditions, using weather reports and radar to choose the smoothest possible path.

The Little Rock to Las Vegas 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

• Convective Turbulence: The Ozark Plateau frequently lies at the convergence of contrasting air masses, fueling thunderstorms and convective 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.
• 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?

The fall months generally offer the smoothest flights on this route. Winter and summer are also fairly mild, though winter may bring clear-air turbulence and summer can see some convective activity. Spring, early summer, late winter, and early spring tend to be the bumpiest times to fly this route. The combination of convective thunderstorms in Tornado Alley and the potential for mountain wave turbulence over the Rockies creates more opportunities for a less smooth ride during these transitional seasons.

Tips for This Flight

If possible, consider booking your flight for the morning, as thermal activity in the desert and afternoon thunderstorms are less likely then. Any turbulence you experience will probably feel like driving on a bumpy road or a boat gently rocking on the water. To help stay calm, choose a seat over the wing; this area experiences less motion. Remember to stay hydrated, and focus on slow, deep breaths; knowing your pilots are expertly managing the flight can also bring peace of mind.
