You'd need some xenon flashes for the lightning run with
special timers -- maybe build something around the old
workhorse Ne555 analogue chip. And then maybe a felt
covered hammer (from an old piano) striking a cookie sheet
or tin sheet for thunder -- hmmm, and a linear
electromagnetic motor to move the hammer??? maybe go
digital soundtrack--definitely need a subwoofer to get down
below 30Hz.
And sprinklers -- you'd need sprinklers for rainfall --
that would be easy enough. I don't think there's a way to
make clouds and have them hold together for any length of
time.
