Tucson to Milwaukee Turbulence Forecast

What to Expect

The Tucson to Milwaukee flight presents a diverse range of potential turbulence, owing to the varied geographical features below. Initially, the aircraft crosses the Mojave and Sonoran Deserts, where thermal turbulence, caused by rising warm air, may be encountered. As you proceed northeast, the flight path crosses the Southern Rockies, which are notorious for mountain wave turbulence as wind flows over the peaks. Further along the route, over the Great Plains, clear-air turbulence (CAT) becomes a possibility. This form of turbulence occurs in the absence of clouds or visible weather patterns. The plane then traverses Tornado Alley, where severe convective turbulence is possible, especially when storms are present. Near the destination, over the Great Lakes, the flight could experience lake-effect turbulence. Finally, you'll cross the Mississippi Valley, where convective turbulence is again a possibility, and the Upper Midwest, where clear-air turbulence (CAT) may occur.

The Tucson to Milwaukee 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

• Thermal Turbulence: Extreme desert heating generates strong thermal updrafts that cause low-to-mid-level turbulence, especially in summer afternoons.
• Mountain Wave Turbulence: The Southern Rockies produce lee waves when southwesterly upper-level winds flow across the terrain.
• 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 experience on this route, aim to fly during the fall or winter months. During these periods, the atmosphere tends to be more stable, reducing the likelihood of thermal and convective turbulence. Summer, late winter, spring, early spring, early summer, late fall and early winter, on the other hand, tend to be bumpier due to increased thermal activity over the deserts, stronger winds over the Rockies, and the potential for severe weather in Tornado Alley and the Mississippi Valley. Spring and early summer also see increased convective activity, increasing the possibility of thunderstorms and related turbulence.

Tips for This Flight

If possible, scheduling your flight for the morning often leads to a smoother ride, as thermal activity and storm development tend to increase later in the day. Any turbulence you might experience on this route will most likely feel like driving on a road with a few potholes, or perhaps some gentle rocking. For added comfort, consider choosing a seat over the wing; this is often the most stable part of the aircraft. Focus on deep, steady breathing and stay well-hydrated; you've got this.
