Chicago Midway to New Orleans Turbulence Forecast

MDW → MSY · 827 miles · ~2h 9m

What to Expect

Flying from Chicago Midway (MDW) to New Orleans (MSY) means covering a good chunk of ground, and the ride can vary. Early in the flight, expect the possibility of Lake-Effect Turbulence as you cross the Great Lakes. This occurs when cold air passes over the warmer lake waters, creating instability. Further south, as you move over the Ohio and Mississippi Valleys, Frontal Turbulence becomes a factor, especially if there are any weather fronts moving through. Finally, as you approach New Orleans and fly over the Southeast Interior and Gulf Coast, Convective Turbulence, caused by rising warm air, is possible. Keep in mind, pilots are pros at navigating these well-understood weather patterns. They use weather reports and radar to avoid the roughest patches, so the bumps are usually manageable.

Between Chicago Midway and New Orleans, the flight path crosses the Great Lakes region. The lakes create their own micro-climate: cold-season lake-effect convection can produce localized but sharp turbulence at lower altitudes, while strong temperature contrasts between the water and surrounding land generate low-level wind shear, particularly during fall and early winter.

Turbulence Factors on This Route

• Lake-Effect Turbulence: The Great Lakes produce lake-effect convection and low-level wind shear from land-water temperature contrasts.
• Frontal Turbulence: The Ohio Valley is a preferred storm track where frontal boundaries and embedded convection create turbulence year-round.

When Is This Route Bumpiest?

For the smoothest possible flight, aim to travel this route in the summer, early fall, or fall. During these months, the atmospheric conditions tend to be more stable. Late fall, winter, spring, early summer, and summer can bring more turbulence. The Great Lakes produce significant Lake-Effect Turbulence in late fall and winter. Spring, early summer, and summer are peak times for thunderstorms in the Mississippi Valley and along the Gulf Coast, increasing the chances of Convective Turbulence. Frontal Turbulence can occur throughout the year, though it is more frequent during the transition seasons of spring and fall.

Tips for This Flight

If you are concerned about turbulence, booking your flight for a morning departure is your best bet, as the air is often calmer earlier in the day before Convective Turbulence has a chance to build. Any turbulence you might encounter on this route is likely to feel like driving on a slightly bumpy road or the sensation of a small dip on a roller coaster; it's usually more of a nuisance than anything alarming. To help stay relaxed, choose a seat over the wing, which tends to experience less motion. Staying well-hydrated can also help you feel more comfortable. Remember, the pilots and flight attendants are there to ensure a safe and smooth flight, so try to settle in and trust their expertise.
