Beaver('s) Tail[Slang], a particular type of inflow band with a relatively broad, flat appearance suggestive of a beaver's tail. It is attached to a supercell's general updraft and is oriented roughly parallel to the pseudo-warm front, i.e.
beavertail antenna"A type of radar antenna that forms a beam having a greater beam width in azimuth than in elevation, or vice versa. In physical dimensions, its long axis lies in the plane of smaller beam width.
Beaver tail (or sometimes inflow stinger - [slang] a low, flat cloud, often shaped like a beaver tail, located in the invlow region of a thunderstorm (the east or southeast side); a particular form of feeder band.
BEAVERS TAIL - A cloud feature on the inflow side of an active thunderstorm, usually a supercell, which resembles the tail of a beaver. This is a type of inflow band or accessory cloud.
A beaver tail cloud with a stinger-like shape.

In hydrologic terms, movement of gravity water in the zone of aeration from the ground surface toward the water table.
Compare with beaver tail, which is a form of inflow band that normally attaches to the storm's main updraft (not to the wall cloud) and has a base at about the same level as the updraft base (not the wall cloud).
This is another type of "tail cloud," with the appearance of a beaver's tail. The east-west oriented cloud frequently is seen in the vicinity of the stationary gust front or "pseudo-warm front," which is northeast of the rotating updraft.
It extends outward from at or near the mesocyclone centre, usually toward the east or southeast, and normally is either nearly stationary or moves northward or north-eastwards ahead of the mesocyclone. See pseudo-cold front and beaver tail.
