- Convective showers become Virga as they diminish
- W960093Z
- Instability, daytime heating and topography have all contributed to the formation of convective showers which are now diminishing and evaporating. A frozen anvil plume overhead is trailing showers of snow and ice crystals which melt and evaporate (sublimate) as they descend. These streaks do not reach the ground and are called Virga.
