Thundersnow, also known as a winter thunderstorm or a thundersnow storm, is a thunderstorm in which snow falls as the primary precipitation instead of rain. It is considered a rare phenomenon. [1] It typically falls in regions of strong upward motion within the cold sector of an extratropical cyclone. Thermodynamically, it is not different from ...
An extremely powerful extratropical bomb cyclone began in late October 2021 in the Northeast Pacific and struck the Western United States and Western Canada. The storm was the third and the most powerful cyclone in a series of powerful storms that struck the region within a week. [1][8][9] The cyclone tapped into a large atmospheric river and ...
Cumulonimbus (from Latin cumulus 'swell' and nimbus 'cloud') is a dense, towering, vertical cloud, [1] typically forming from water vapor condensing in the lower troposphere that builds upward carried by powerful buoyant air currents. Above the lower portions of the cumulonimbus the water vapor becomes ice crystals, such as snow and graupel ...
In addition to the heavy rain, thunderstorms and accumulating snow, this powerful storm will likely pack a punch in terms of wind gusts across the central and eastern United States this weekend ...
Storms tracking out of the West and into the Plains, in tandem with cool air clashing with warm, moisture-rich air, will spark the risk of heavy rain, severe weather and even snow for some areas.
Squall. A squall is a sudden, sharp increase in wind speed lasting minutes, as opposed to a wind gust, which lasts for only seconds. [1] They are usually associated with active weather, such as rain showers, thunderstorms, or heavy snow. [2] Squalls refer to the increase of the sustained winds over that time interval, as there may be higher ...
Severe thunderstorms, heavy rain and snow are expected to move from the central US across the Midwest and ultimately into the northeast just in time for the holiday.
Very common rain, snow, snow pellets or hail, heavy at times. A cumulonimbus incus (from Latin incus 'anvil'), also called an anvil cloud, is a cumulonimbus cloud that has reached the level of stratospheric stability and has formed the characteristic flat, anvil -shaped top. [1] It signifies a thunderstorm in its mature stage, succeeding the ...
