Most mini supercells have been found in environments characterized by low strong vertical wind shear as found under a tropical cyclone (e.g., McCaul 1987 ) or an extratropical cyclone ( Davies 1993 Mixed-Layer CAPE > 1000 is pretty solid, 2000-3000 is better, 4000+ is extreme instability Hail rips through Burnett and Bureau of Meteorology forecasts more supercells on the way By Scott Lamond and Megan Hughes, Friday October 23, 2020 - 13:22 Farmers west of Bundaberg say Thursday's hail storm was one like they have never seen before and the weather bureau is warning it may just be a taste of what's ahead over the next week. Many of these "examples" of supercells do not appear to be related to supercells at all - they describe severe tornados and other severe weather events. If there are any references that establish a link between any of those events and a supercell, those references need to be cited; otherwise, the example is invalid for this article and should be removed. 2021-03-11 Although supercells and mega storms are destructive, they have an element of beauty as well. Click through to see stunning images of America’s supercells and mega storms. Classic supercells are common in the Great Plains but can occur in regions where LP and HP supercells are common.
The vast majority of supercells produce some sort of severe weather: hail, damaging straight-line winds, and/or tornadoes; only about 20% of them are tornadic, however. However, rotating supercells displace the rising air (updraft) from the falling rain/hail (downdraft), which allows them to grow more intense and last longer. Regular thunderstorms usually live for tens of minutes, while supercells can go on for hours. Extreme Weather: Supercells.

On radar, discrete supercells sometimes (not always) have a very distinctive appearance (displaying a hook echo). Supercells can be visually stunning (see photograph below), and when it comes to producing dangerous, destructive weather, supercells are a big deal!

EXPLANATION OF SPC SEVERE WEATHER PARAMETERS Rich Thompson - Storm Prediction Center The SPC utilizes all available surface observations, in combination with short-term forecasts from the Rapid Refresh (RAP) model, to generate hourly mesoscale analyses of various parameters related to severe thunderstorms and tornadoes. Determining the type of supercells that may occur within a given severe weather environment is important for a multitude of reasons. A supercell is a thunderstorm that rotates. There are three types of supercells: low-precipitation (LP), classic, and high-precipitation (HP). Detecting Shallow Supercells • Shallow supercells present a particularly difficult forecasting challenge because they are accompanied by the same severe weather elements (including tornadoes) as their bigger counterparts, but are much more difficult to detect at any appreciable distance from the radar.
There are three types of supercells: low-precipitation (LP), classic, and high-precipitation (HP). The configuration of the wind shear profiles within a severe weather environment is critical in diagnosing what types of supercells can be expected on a given day. Asupercell is a widespread, long-lived,rotating windstorm that is associated with severe thunderstorms. Supercells can cause straight-line winds, tornadoes,hail, heavy rains, and flash floods. This single-celled storm has only one dominant updraft of moist, feeding air and one dominant downdraft of cooled air, rain, and possibly hail. The supercell’s compact cumulonimbus structure makes it
Preliminary research suggests that tornadoes become more likely with supercells when LFC heights are less than 2,000 m above ground level, and thunderstorms are more easily initiated and maintained when LFC heights are lower than about 3,000 m. The LFC is this example is for the lifted surface parcel.

Supercells can occur anywhere in the world under the right pre-existing weather conditions, but they are most common in the Great Plains of the United States in an area known as Tornado Alley.
