Wichita to Spokane Turbulence Forecast

What to Expect

Your flight from Wichita to Spokane is a pretty common route, and pilots are very familiar with the weather patterns along the way. You'll be heading northwest, and that means crossing a few different types of terrain that can cause bumps. First, you'll be over the Great Plains, an area notorious for clear-air turbulence, or CAT, which can happen even when the sky looks perfectly clear. Next, you'll fly over Tornado Alley, where, particularly in spring, severe convective turbulence can develop from storm activity. Finally, as you approach Spokane, you'll cross the Northern Rockies, which can create mountain wave turbulence as the wind flows over the peaks. All these types of turbulence are well understood, and pilots use weather forecasts and radar to navigate the smoothest possible path.

The Wichita 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

• 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.
• 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?

The smoothest rides on this route are typically in the summer and fall. Winter can also be fairly calm. The bumpier times tend to be in the spring and early summer, due to storm activity in Tornado Alley and the general instability of the atmosphere as the seasons change. Late fall can be a bit bumpy as well. The Northern Rockies can be affected by mountain wave turbulence, especially during the colder months when stronger winds flow over the mountains.

Tips for This Flight

If you're concerned about turbulence, booking your flight for a morning departure will likely give you the smoothest ride. Storms are less common early in the day. Any turbulence you experience will probably feel like driving on a road with some potholes or hitting a few small waves in a boat. Choose a seat over the wing, which tends to experience less motion, and remember to stay hydrated. Taking slow, deep breaths can also help you relax. Remember that the pilots are trained to handle these conditions, and the flight will get you to your destination safely.
