The winds are almost always much stronger at altitude with the presence of the jet stream. And if there's any type of precipitation at 35,000 feet, it would be ice where the ground would see all types of precipitation such as liquid, rain, or freezing rain, or frozen snow, or hail.

It is extremely rare for it to rain at 35,000 feet, which is the standard cruising altitude for most commercial jetliners. This altitude is typically in the stratosphere, located above the "weather layer" (the troposphere) where 99% of the Earth's water vapor and clouds exist. This is why you often see a clear, blue sky and bright sun out the window even if you took off in a thunderstorm. However, powerful thunderstorms known as "supercells" can occasionally push clouds and precipitation up to 50,000 feet through a process called "overshooting tops." If a plane flies near or through these massive systems, it could encounter "supercooled" water droplets or ice crystals. However, at -50°C (-58°F), any liquid water usually freezes instantly, so you would experience "icing" or heavy turbulence rather than liquid rain. Generally, pilots prefer to fly above or around the weather, so while "precipitation" can technically reach that height, you will almost never see standard rain hitting the cockpit window at cruise.
