A more recent FACETs example... the big wind and tornado at Van Buren, AR this year... data produced by the mesoscale forecaster and radar meteorologist merged to show the increasing threat at Van Buren in advance of warnings and watches...
@rudygamble Ok thanks. I would think the less dense air (added humidity) would offset any time it would take for a ball to saturate enough to weight more. Just my opinion. Please pass along any reference you find about the physics. Thanks again.
