Definition
In aviation weather, describes a thunderstorm or other significant convective cell that is concealed within a larger mass of cloud, typically widespread stratiform cloud, so that it cannot be visually identified and avoided in the normal way.
Plain English
Hidden inside other clouds. The dangerous storm cell is buried in a bigger blanket of cloud, so the pilot cannot see it coming and has to rely on radar or weather reports to know it is there.
Context Anchor
Used in weather briefings, forecasts, and instrument flying discussions, especially with embedded thunderstorms.
Derivation
From Latin roots meaning 'fixed firmly within' something else. In aviation use, it carries that same sense: the storm is set into the surrounding cloud mass, not standing alone where it can be seen and circumnavigated.
Why Pilots Care
Raises the risk of surprise entry because the storms cannot be spotted visually or avoided by circumnavigation.
Intuition Check
Embedded does not just mean “included.” In aviation weather, it means hidden inside a larger area, making it harder to see and avoid.
Example Sentence 1
The convective SIGMET reported a line of embedded thunderstorms across the route, so the crew requested a deviation well before reaching the cloud mass.
Example Sentence 2
Controllers advised of embedded cells along the route, hidden within the frontal cloud deck.
