Echo overhang

From Glossary of Meteorology

echo overhang

In the radar echo associated with a severe thunderstorm, the portion of the echo that is located above the weak-echo region on the low-altitude inflow side of the storm.

The overhang consists of precipitation particles diverging from the storm's summit that descend as they are carried downwind. If the storm echo develops a bounded weak-echo region, it is found within the echo overhang.
