Update...
taking a close look at the hi-res model runs...it looks like there
should be a good chance for patchy fog...occasionally dense...and from
del Rio to Sat and north. The moisture depth is shallow...but with
with forecast dewpoint depressions at or above 1 degree or less off and on
the Escarpment...T overs of as low as -6...and a good radiational
set up initially with the clear skies and light winds...the
confidence in fog of some kind is pretty high. Therefore expanded
the weather grid to include all of Bexar County and up to
Fredricksburg from 10z to 13z.

Aviation...
similar to Thursday night...VFR conditions will last through 09-10z
before condensation quickly produces MVFR stratus. Models and
persistence indicate MVFR br at kdrt. There is a possibility br
may occur at kaus pending additional model runs/observation trends.
Otherwise...look for ceilings to lift at all sites through 15z Saturday...
but only completely mix out at kdrt. An approaching trough will increase
winds after 15z at the I-35 sites...where 12-15kt and gusts of 22-25kt
are likely.
