hitting the Polar Jetstream over Western Arizona at 41,000 ft aboard a United Boeing 787-8 Dreamliner and experiencing some moderate turbulence.
Due to a jet streak off the US Pacific Coast, the Polar JetStream bended very much to south over the Desert Southwest.
We’ve probably hit a spot in the Polar Jetstream, where the wind band was quickly changing its direction (from a southerly to a more eastern flow). The Jetstream, though, didn’t bring a large weather system with it, hence, you don’t see any clouds. It’s a case of moderate clear air turbulence.
