New Orleans to Spokane Turbulence Forecast

MSY → GEG · 1,890 miles · ~4h 17m

What to Expect

The New Orleans to Spokane flight is a journey across a wide range of landscapes, each with its own potential for turbulence. Departing from the Gulf Coast and heading northwest, you'll initially encounter the risk of convective turbulence, common in that region. As you cross the Mississippi Valley and enter Tornado Alley, be aware that severe convective turbulence can occur, especially during certain times of the year. Further along, over the Great Plains, clear-air turbulence, or CAT, may be present, a phenomenon caused by differing air currents. Finally, as you approach Spokane and fly over the Northern Rockies, you might experience mountain wave turbulence, created as air flows over the mountains. These are all normal weather patterns, and pilots are trained to navigate them safely.

The New Orleans to Spokane route crosses the Northern Rockies, a rugged expanse of high peaks in Montana, Idaho, and Wyoming. Mountain wave turbulence is frequent here, especially when Pacific storm systems push strong winds over the Continental Divide. Pilots often report moderate chop between 30,000 and 40,000 feet over this region.

Turbulence Factors on This Route

• Convective Turbulence: Warm Gulf moisture drives rapid thunderstorm development along the coast, creating intense updrafts and downdrafts.
• 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 Northern Rockies generate powerful lee waves when Pacific fronts drive westerly flow across the high terrain.

When Is This Route Bumpiest?

For the smoothest flight experience on this route, aim to travel during the winter or early spring. Fall can also be a good option. During these seasons, the convective turbulence is less frequent and intense, and the risk of severe convective turbulence is lower. Summer, late fall, and early summer tend to be the bumpiest times to fly this route. This is due to increased convective activity along the Gulf Coast and throughout the Mississippi Valley, plus the higher likelihood of thunderstorms in Tornado Alley, all contributing to more turbulence.

Tips for This Flight

To minimize any anxiety, consider booking your flight for the morning, as turbulence is often less pronounced earlier in the day. Any turbulence you do experience on this route is most likely to feel like driving on a bumpy, unpaved road for a little while; it's rarely anything more dramatic. Choose a seat over the wing, as it tends to offer a slightly more stable ride. Stay hydrated and remember to breathe deeply; many passengers find that focusing on their breath helps them feel more relaxed and in control. Remember, pilots are highly skilled at managing turbulence, and your safety is always their top priority.
