Oklahoma City to Des Moines Turbulence Forecast

OKC → DSM · 475 miles · ~1h 27m

What to Expect

Your flight from Oklahoma City to Des Moines, a roughly 1 hour and 27 minute hop to the northeast, crosses some interesting terrain, turbulence-wise. Initially, you'll be flying over the Great Plains, an area known for clear-air turbulence (CAT). This type of turbulence is often caused by changes in wind speed and direction at high altitudes, and can be tricky to predict. Later, the route takes you through Tornado Alley. While you hopefully won't encounter an actual tornado, this region is prone to severe convective turbulence, especially during certain times of the year. Severe convective turbulence is caused by rapidly rising warm air, forming thunderstorms. Remember that pilots are highly trained to navigate these weather patterns, using radar and reports from other aircraft to avoid the roughest patches. They constantly monitor conditions to ensure a safe and comfortable flight as much as possible.

Between Oklahoma City and Des Moines, the route crosses the Great Plains, a vast, flat expanse where clear-air turbulence from jet stream undulations is the primary concern at cruise altitude. The lack of terrain features means mountain wave turbulence is absent, but the jet stream frequently meanders over this region, creating wind shear zones at flight levels.

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.

When Is This Route Bumpiest?

For the smoothest possible ride on this route, consider flying during the summer or fall. These seasons tend to be more stable over the Great Plains and Tornado Alley, reducing the likelihood of significant clear-air or convective turbulence. Winter and early spring, as well as spring and early summer, are typically the bumpiest times to fly this route. The increased instability in the atmosphere during these transitional seasons leads to stronger storms and more frequent clear-air turbulence events. The change from warm to cold, or cold to warm, brings stronger winds at altitude, which causes more clear air turbulence.

Tips for This Flight

If possible, try to book a morning flight. The atmosphere is often calmer earlier in the day, reducing the chance of turbulence. Any turbulence you do experience on this route will likely feel like driving on a bumpy road or encountering strong gusts of wind while sailing. To help stay relaxed, choose a seat over the wing, as this area experiences less motion. Remember to stay hydrated and practice deep, slow breathing; this can help calm your nerves. Remember, your pilots are experienced professionals, and passenger safety is always their top priority.
