Anchorage to Memphis Turbulence Forecast

ANC → MEM · 3,147 miles · ~6h 48m

What to Expect

Your flight from Anchorage (ANC) to Memphis (MEM), a journey eastward across 3147 miles, does have a few typical turbulence zones. Early in your flight, as you cross the Great Plains, you might encounter clear-air turbulence (CAT). This is caused by shifting air currents at high altitudes, which pilots are very familiar with and prepared for. Later, as you pass over the Ozark Plateau and then the Mississippi Valley, convective turbulence could be present. This is caused by rising warm air; think of it like the atmospheric version of small ripples on a lake. Finally, over the Southeast Interior, the same kind of convective turbulence might occur. Remember, pilots get frequent weather updates and adjust altitude or course to find the smoothest possible ride. These are common, well-understood phenomena on this route, not surprises.

Between Anchorage and Memphis, 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.
• Convective Turbulence: The Ozark Plateau frequently lies at the convergence of contrasting air masses, fueling thunderstorms and convective turbulence.

When Is This Route Bumpiest?

The late fall season tends to offer the smoothest flights between Anchorage and Memphis. The atmosphere is generally more stable during this period, minimizing both clear-air and convective turbulence. Summer can also be relatively calm. Winter, early spring, spring, and early summer tend to be bumpier. This is because the temperature differences are greater, leading to more instability and increased chances of both types of turbulence. Warmer temperatures also lead to thunderstorms and more convective turbulence. Therefore, a flight booked in the late fall has the highest likelihood of smooth skies, particularly across the Ozarks, the Mississippi Valley, and the Southeast Interior.

Tips for This Flight

Choosing a morning flight can sometimes mean less convective turbulence, as the ground hasn't had as much time to heat up. When turbulence does occur on this route, it often feels like driving on a slightly bumpy road or a boat gently rocking on the water. Focus on slow, steady breathing, and consider choosing a seat over the wing for potentially less noticeable motion. And remember that the flight crew is highly trained to handle all conditions, including turbulence, and their priority is always your safety and comfort.
