Ask The Weatherman for August 26, 2013:
Question: What kind of weather do pilots receive before each flight?
Answer: Pilots are briefed by a special set of meteorologists that usually belong to the airline. They get information on flight level winds, air temperatures, any turbulence will there be, and any icing that could impact the airplane. They also get briefed on weather conditions at their destination airport, such as will they run into any rain, snow, hail, thunderstorms all of that information. So a pilot does get a pretty in-depth weather brief before they fly for the day.
