[wxqc] Moisture Content

[Victor Engel]

Right. Didn't mean to confuse. Right now there is a storm reading 84
Kg/m^2, and there is no mention of hail.

The problem with the slices is that they're not combined. Or is there
a resource that graphically shows this combined data somewhere that
I'm unaware of.

With this low pressure zone hovering over Texas, I've been enjoying
watching the storms and comparing the various tools out there.
Yesterday, I sent an email to someone pointing out a storm where there
seemed to be a very strong local difference in relative velocities. I
suggested that maybe it would produce a tornado. Half an hour later,
there was a tornado warning from the same storm, somewhat north of
Fredericksburg.
