There are no words to this, just actions. We're going to make the sounds of a rain storm...
Rub two fingers on palm - light drizzle
Rub hands together - drizzle
Tap two fingers from each hand together - soft rain
Snap fingers - light pitter-patter rain
Lightly clap hands - rain
Slap thighs - heavy rain
Stomp feet and slap thighs - downpour
Repeat actions backwards, showing the storm leaving.
