In many snowy locations all over the road, snow tires or snow chains are a necessity for winter travel. In some places, they are even required by law. What's the real difference in performance between chains or tires?
Snow chains are metal chains that are put on tires to increase traction on snow packed roads. Chains limit the fuel efficiency of a vehicle, however. They also work to reduce speeds closer to 30 miles per hour, and are often required for cars that don't have four-wheel drive.
Snow tires contain more natural rubber to prevent them from hardening in the cold. They also have treads that are better designed for from maintaining control on snow-packed roads.
Why can different types of precipitation be seen on Earth while temperatures remain constant?
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?

Supercell thunderstorms have been responsible for major tornadoes that have demolished parts of the U.S.
After a cold, clear winter night without much wind, the ground and nearby tree branches may be covered by tiny, white ice crystals.
A major cause of post-snow flooding are ice jams in waterways.
