You'll notice that the photos at Code One magazine by Lockheed, and photos in other sources, that the F-35 is never pictured entering or departing clouds.

"Restrictions on the aircraft operating limits prevented instruction in most high performance maneuvering and flight through instrument meteorological conditions (i.e., clouds)."
