.DISCUSSION...Updated for 06Z /1 AM/ Aviation Update.
.AVIATION...As expected this time last night...clearing did occur
during the early evening as drier air was able to nudge out the
clouds with the onlyh exception some resurgence across the
ranchlands. Expect some low VFR development toward daybreak which
isn`t that unusual in increasing return southeasterly flow.
Thereafter, any morning ceilings will lift and scatter out as dry
air from below and above do the work that was not available on
Wednesday; rather than a 1 thousand foot layer of saturation there
is just a very small such layer from late morning through sunset
which implies plenty of sunshine through fair weather cumulus. The
main issue today will be the Valley wind machine with sustained
speeds rising to or above 20 knots by 18Z and continuing through
sunset before diminishing, but only to 10 knots or so with low
level jet continuing. Dry enough air remains to keep skies
FEW to SCT at least through 06Z.
