980623 - ANOTHER GREAT NULL CASE!  A supercell moved to the southeast along
and over US26 (how convenient!) near Broadwater and Lisco, Nebraska, during
the evening and we sampled it extensively.  Tornado-strength low-level
rotation was noted on several occasions, but no tornado formed.  VORTEX
observed an interesting variety of precipitation in the RFD's.  An early
transect indicated tiny droplets with no real discernible divergence
signature at the surface.  On a later transect, there was moderate rain and
1" hail, with a very dramatic divergence zone (on the order of a few
hundreds of meters scale) colocated with an intense surface anticyclone in
the hook precipitation.  It's fairly certain that we were in a
anticyclonically flared hook immediately west of the surface cyclone
position.  The RFD was "scuddy", and the anticyclonic shear/rotation in the
RFD area was very pronounced ... often tornado strength.  In fact, we saw
about 6-12 laminar anticyclonic funnels in the RFD periphery.
