Freezing fog occurs when the water droplets that the fog is composed of are "supercooled." Supercooled water droplets remain in the liquid state until they come into contact with a surface upon which they can freeze. As a result, any object the freezing fog comes into contact with will become coated with ice. The same thing happens with freezing rain or drizzle.
The after-effects of frozen fog, as photographed by Flickr user Amy Woodward. "Woke up to this winter wonderland which, according to the weatherman, is caused by frozen fog. The air was filled with sparkles as it melted off the trees."
Dangerous flash flooding is captured as an arroyo becomes filled with water in Carson Valley, Nevada.
The RealFeel Temperature uses an equation to determine how it actually feels outside.
Knowing what the different advisories, watches, and warnings mean will lead to more informed decision making when a winter storm threatens a particular area.
How can you determine if and when the ice is thick enough for safely going out on?
Seeking shelter in the event of a tornado could save your life, but is there really any safe place to hide?
Driving on a 90-degree angle away from the tornado is a good strategy to follow in order to distance yourself from the tornado.
Supercell thunderstorms have been responsible for major tornadoes that have demolished parts of the U.S.
A major cause of post-snow flooding are ice jams in waterways.
How can there be a blizzard if it's not snowing outside? Justin Povick explains.
Any time snow is in the forecast, milk and bread fly off the shelves at grocery stores. Why?
