My dreams usually have realistic vorticity production terms, so it's good to 
hear about one that doesn't.

Most of us dream about weather, but only Mark Branson would analyze the weather
in-dream to the extent of assessing convective precip in non-convective cloud 
systems.

I had a dream I was eating grapefruit-sized hail, and when I woke up, my
updraft was gone.

Most of my dreams are about getting stretched out too much-sometimes I also
dream I move into subsiding, irrotational flow, but I quickly wake up before that happens. 
Usually that happens right when I'm first falling asleep though.

Looking back at the comments page for Mark Branson's entry, I erred... for
some reason I was thinking that Mark's dream of giant hailstones involved
a giant tornado as well (wishful thinking, I'm certain), thus my comment
about a "realistic vorticity production term."

I was about to retract this comment.  However on second thought I will
stand by it and defend it.  Mesoscale rotation is associated with an
enhancement in the vertical perturbation pressure gradient, and a larger
gradient will enhance updraft strength and thus contribute to the growth
of larger hailstones.  Such rotation and associated pressure gradients are
unlikely to be associated with a stratus deck, so I maintain the
importance of the vorticity production term in this dream.
