Hi there, long-time lurker, but have been following this newsgroup
closely over the past couple of weeks watching Will's very early snow
prediction coming to pass - very exciting to follow! What was the
phrase that hooked me in? "Significant snow event"?

Anyway, I'm modelling a wintry scene in 3D on the computer for an
animation, and would like to know if it's possible to have a snow
shower whilst there's heavy fog?

Don't forget that if the snow is heavy enough the effect on visibility
will be much the same as fog.
