Speaker Notes:

• The lowering of the rain free cloud base is called a ‘wall cloud’. Wall clouds point down and toward the rain, but maintain their position relative to the rain, unlike shelf clouds.

• Again, just because there is a wall cloud doesn’t mean there will be a tornado, and we ask SKYWARN^TM spotter to contact the NWS not when they see a wall cloud, but if the wall cloud begins to rotate.
