.AVIATION [18Z TAF Issuance]...

An IFR deck is continuing to push in from the NW this afternoon,
impacting UTS and CXO. Otherwise, ceilings ranging between
MVFR/VFR across the rest of SE TX, with VFR conditions closer to
the coast. Expecting ceilings to rise to high MVFR across the
metro and northern TAF sites this afternoon before lowering again this
evening. Scattered SHRA along the stalled stationary front will
continue this afternoon, currently concentrated along the metro
and coastal sites where the boundary is situated. A secondary
round of showers will be possible beginning shortly after sunset,
moving in from the north with better chance for coverage
impacting the metro and northern TAF sites. LIFR/VLIFR ceilings
will return along the coast overnight, with visibilities falling
to VLIFR criteria at GLS. SGR to HOU and northward will see
ceilings fall to IFR criteria by early Sunday morning. Ceilings
should begin to rise for these sites by mid morning.

.PREV DISCUSSION /Issued 1051 AM CST Sat Feb 17 2018/...

Not planning on any major changes with the forecast at this time.
The sea fog appears to have dissipated over the bays so far this
morning...but is still lingering over the nearshore waters. This
reprieve should be short-lived as the weak cold frontal boundary
remains stalled just inland over SE TX. Overrunning showers will
likely continue through the afternoon as well given the persist-
ent SW flow aloft. 41
