Heavy Snow in U.S. Midwest (NASA's Earth Observatory) -
A severe winter storm hammered the Midwestern United States on December 1, 2006. According to news reports, the storm iced roads, canceled flights, broke tree branches, left more than two million homes and businesses without electricity, and temporarily shut down part of Interstate 40 in central Oklahoma.
Contrails Over the Midwest (NASA's Earth Observatory) -
When the hot, humid air from a jet engine mixes with colder, drier air in the surrounding environment, condensation trails, or “contrails,” streak the sky. If the air through which the airplane is flying is already close to being saturated with water vapor, the condensation trail will last longer than it will if the air is dry.
