My memory from my atmospheric physics days is that the water content of
a nice cumulonimbus is around 1 gram per cubic meter. Assume the
smallest cloud is a cubic kilometer and that gives you a billion grams,
or a million kilograms, or a thousand metric tons of water. That's
ignoring the weight of the air, too.

Not as light and fluffy as they look.

Interesting. When I started, my instructor told me the weight of upward
moving air in the core of a moderate thermal was about 80 tons. Haven't
ever done the figures to check the accuracy of that estimate.
