Overshooting Tops indicative of powerful updrafts
Looking east from about 40 miles away, we see a line of towering cumulus clouds and a large supercell storm in the background.
overshooting top"(Or anvil dome, penetrating top.) A domelike protrusion above a cumulonimbus anvil, representing the intrusion of an updraft through its equilibrium level (level of neutral buoyancy).
Overshooting Top (or Penetrating Top) - a dome-like protrusion above a thunderstorm anvil; it represents a very strong updraft and, hence, a higher potential for severe weather with that storm.
OVERSHOOTING TOP - A 'bubble' of cloud sticking up above the anvil of a thunderstorm, due to a vigorous updraft within the storm.
Overshooting top
This "dome" feature appears above the anvil of the storm. It is a result of the powerful updraft.

Percentile
The term for denoting thresholds or boundary values in frequency distributions.
A large overshooting top or penetrating top.
Anvil Rollover
Slang for a circular or semicircular lip of clouds along the underside of the upwind part of a back-sheared anvil, indicating rapid expansion of the anvil.
DOME - An overshooting top of convection past the equilibrium level above the top of a thunderstorm. This is usually the top of the updraft plume. Also used as the name given to a high pressure cell.
Penetrating TopSame as Overshooting Top; a dome-like protrusion above a thunderstorm anvil, representing a very strong updraft and hence a higher potential for severe weather with that storm.
Penetrating Top - Same as overshooting top.
Popcorn Convection - [Slang], Showers and thunderstorms that form on a scattered basis with little or no apparent organization, usually during the afternoon in response to diurnal heating.
Penetrating Top Same as overshooting top.
Perched Groundwater Local saturated zones above the water table which exist above an impervious layer of limited extent.
However, strong updrafts will continue to rise past the EL before stopping, resulting in storm tops that are higher than the EL. This process sometimes can be seen visually as an overshooting top or anvil dome.
Visual characteristics often include a rain-free base (with or without a wall cloud), tail cloud, flanking line, overshooting top, and back-sheared anvil, ...
See overshooting top, cyclic storm.Qualitative forecastsForecasts that provide only a categorical value for the predicted variable. Examples of this include ârain/no rainâ and âcloudy/partly cloudyâ.
