Wintry showers is a somewhat informal meteorological term, used primarily in the United Kingdom, to refer to various mixtures of rain, graupel and snow at once. Though there is no "official" definition of the term, in the United Kingdom it is not used when there is any significant accumulation of snow on the ground.
A shower will produce rain if the temperature is above the freezing point in the cloud, or snow / ice pellets / snow pellets / hail if the temperature is below it at some point. [1] In a meteorological observation, such as the METAR, they are noted SH giving respectively SHRA, SHSN, SHPL, SHGS and SHGR. [2] [3]
Heavy rain describes rainfall with a precipitation rate above 7.6 millimetres (0.30 in) per hour, and violent rain has a rate more than 50 millimetres (2.0 in) per hour. [11] Snowfall intensity is classified in terms of visibility instead. When the visibility is over 1 kilometre (0.62 mi), snow is determined to be light.
Graupel (/ ˈ ɡ r aʊ p əl /; German: [ˈɡʁaʊpl̩] ⓘ), also called soft hail or hominy snow or granular snow or snow pellets, [1] is precipitation that forms when supercooled water droplets in air are collected and freeze on falling snowflakes, forming 2–5 mm (0.08–0.20 in) balls of crisp, opaque rime.
Drenching rain or spotty rain showers will precede the arrival of an Arctic cold front. "Along that front and immediately behind it is where and when the snow showers and heavier snow squalls can ...
Progressively colder air will lead to the first snowflakes and snowfall of the season, as well as the first freeze in parts of the North and Northeast.
Multiple lighter flurries, snow showers and a heavy snow squall can occur at any one given location, with the greatest danger being where snow did not fall and accumulate on area roads from the ...
A snow flurry is a light snowfall that results in little or no snow accumulation. The US National Weather Service defines snow flurries as intermittent light snow that produces no measurable precipitation (trace amounts). [1] In contrast, bursts of snowfall that do result in measurable snow accumulation are called snow showers. [2]
