Pittsburgh to Spokane Turbulence Forecast

What to Expect

Flying from Pittsburgh to Spokane involves crossing a variety of terrains, which means experiencing a few different types of turbulence. Shortly after takeoff, you might encounter some frontal turbulence related to weather fronts in the Ohio Valley, but these are usually brief. As you continue northwest, crossing the Great Lakes, be prepared for some lake-effect turbulence, particularly if the air is colder. As you pass over the Upper Midwest and the Great Plains, you might feel some clear-air turbulence, or CAT. CAT can occur even when the sky looks clear, caused by shifting air currents at higher altitudes, which pilots are very skilled at managing and predicting. Finally, approaching Spokane, you'll fly over the Northern Rockies, where mountain wave turbulence is common. These bumps are created as air flows over the mountains, creating waves. Remember, pilots are trained to handle these common weather patterns, and they constantly monitor conditions to ensure a safe and comfortable flight.

The Pittsburgh 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

• Frontal Turbulence: The Ohio Valley is a preferred storm track where frontal boundaries and embedded convection create turbulence year-round.
• Lake-Effect Turbulence: The Great Lakes produce lake-effect convection and low-level wind shear from land-water temperature contrasts.
• Clear-Air Turbulence (CAT): The Upper Midwest sits beneath frequent polar jet stream intrusions, producing 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 possible ride on this Pittsburgh to Spokane route, aim for summer or early fall. The air is generally more stable during these times, minimizing the chances of significant turbulence over the Great Lakes and the Rockies. Winter, spring, late fall, and early spring tend to be bumpier, with stronger weather fronts in the Ohio Valley, more pronounced lake-effect turbulence, and increased chances of clear-air turbulence and mountain wave turbulence, as the jet stream shifts and temperature differences are more extreme.

Tips for This Flight

If you're concerned about turbulence, booking a morning flight often results in a smoother experience, as the atmosphere tends to be more stable earlier in the day. Any turbulence you encounter on this route will likely feel like driving on a slightly bumpy road or a brief roller coaster dip. Remember to stay hydrated, as dry air can amplify any anxiety you may feel. Choosing a seat over the wing may also provide a more stable ride. Take slow, deep breaths, focusing on your exhale to calm your nervous system; you will be in good hands.
