Wichita to Des Moines Turbulence Forecast

ICT → DSM · 335 miles · ~1h 10m

What to Expect

That Wichita to Des Moines flight is interesting because it crosses a couple of key geographic features that can influence turbulence. Initially, you'll be over the Great Plains, which means you might encounter clear-air turbulence, or CAT, which is caused by shifting air currents at higher altitudes. Later, the flight path takes you through a portion of what's known as Tornado Alley, where, especially during certain times of the year, severe convective turbulence can occur due to rapidly rising warm air and storms. It's important to remember that pilots are very familiar with these patterns. They use weather forecasting and onboard radar to navigate around any significant turbulence, making adjustments to altitude or route as needed. These are well-understood conditions, and your flight crew is trained to handle them safely and effectively.

Between Wichita 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?

The smoothest rides on the Wichita to Des Moines route are typically in the summer and fall, as well as winter. The atmosphere tends to be more stable during these times, minimizing the chances of turbulence. In contrast, late winter, early spring, spring, and early summer can be bumpier. This is because Tornado Alley comes alive, and the clash of warm and cold air masses leads to the formation of thunderstorms and the associated turbulence.

Tips for This Flight

If you're concerned about turbulence on this route, try to book a morning flight; the air is often calmer earlier in the day. Any turbulence you do encounter on this flight will likely feel like driving over a series of small, unexpected bumps in the road, or perhaps a mild roller coaster. To help stay calm, consider choosing a seat over the wing, as it's typically the most stable part of the plane, and remember to stay hydrated. Taking slow, deep breaths can also work wonders. Remember, the pilots are there to ensure a safe flight, and they're constantly monitoring conditions.
