A question meteorologist get asked all the time during the cold winter months is "can it ever be too cold to snow"? Well, the short answer is no.
The ingredients for snow are:
1. A temperature profile that allows snow to reach the surface
2. Saturated air
3. Enough lifting of that saturated air to allow snow to develop aloft and fall to reach the surface
The phrase "it's too cold to snow" probably originated as a misapplication of the relationship between temperature and the maximum amount of water vapor that can be in the air. When temperature decreases, the maximum capacity of water vapor that can be in the air decreases. Therefore, the colder it gets the less water vapor there will be in the air.
Most heavy snowfalls happen with relatively warm air temperatures near the ground -- usually at 15 degrees F or above. When the temperature drops into the single digits, or below zero, heavy snow is unlikely. That's not because it's too cold, but because its too dry. When temperatures are that low, the air's capacity for water vapor becomes very small.
Experts say only at absolute zero would snow become impossible. Along with everything else.
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?
What conditions cause snow to be dense and wet instead of light and powdery?
In order to get an accurate snow measurement, measure the depth of the snow.
Omaha, NE (1923)
16.4" of snow.
The first storm referred to as a blizzard. March 14th-16th... An editor at the "Dakota Republican" in Vermillion, SD, described the storm. "A violent snowstorm driven by a heavy (northwesterly) wind, commenced about 12 o'clock last Sunday night (12th) and continued three whole days and nights. The weather was intensely cold and the heavy fall flying before a furious wind - blowing as only prairie winds can blow - rendered travelling exceedingly uncomfortable and dangerous, if not almost impossible (issue of March 17, 1820)."
South Carolina (1991)
Early morning severe thunderstorm produced hail to 2.5" in diameter. Hardest hit was Lexington County. The hail destroyed a brand new pickup truck in Gaston.
