Area Forecast Discussion...UPDATED
National Weather Service Corpus Christi TX
901 PM CST Thu Feb 23 2017

.DISCUSSION...Sea breeze boundary has pushed inland with higher
dewpoints into eastern portions of the Brush Country. Moist
boundary layer is very shallow underneath a very strong inversion
around 1000 feet on the 00Z CRP sounding. This is leading to a
strong anomalous propagation on KCRP radar especially over the
Gulf of Mexico as radar wave is being ducted underneath this
inversion. Adjusted wind speeds for this evening along the coast
as winds are a little stronger over the northern bays with SCEC
conditions until around midnight. Trough axis will move into the
Brush Country overnight with winds becoming light over the coastal
plains and gradually veering. With dewpoint temperatures in the
mid to upper 60s over the coastal plains and very dry air just
above the surface, still looks like the inland coastal plains will
see a period of fog from 10-15Z Friday. Winds will be a little
stronger closer to the coast, so dense fog not likely in this
region. But dense fog could occur along a ALI-BEA-VCT line.

.PREVIOUS DISCUSSION... /Issued 548 PM CST Thu Feb 23 2017/

DISCUSSION...See Aviation section for 00Z TAFs.

AVIATION...Smoke from earlier fire down in Kenedy County has
moved northeast across the Coastal Bend with smoke layer around
5 Kft. Smoke layer will continue to move northeast early this
evening. Otherwise, clear skies will continue this evening with
gusty southeast winds over the Coastal Bend for a few more hours
due to the strong thermal gradient. Sea breeze boundary has moved
inland to along Highway 281 and will continue to advance inland
this evening. Dewpoint temperatures are in the lower 60s right
behind the sea breeze boundary and near 70 along the coast. The
moist boundary layer will be very shallow tonight with very dry
air above. Winds will become light after midnight as trough axis
moves into the eastern Brush Country. Expect areas of fog/IFR
vsbys will develop around 08Z over the inland coastal plains and
become dense/LIFR by 10Z. Winds may be slightly stronger at CRP
to limit fog from becoming dense. The trough axis will move
through the coast early Friday morning ahead of the frontal
boundary moving into the Brush Country. May see brief period
from 12-15Z of fog/stratus along the front affecting the COT area.
Otherwise, conditions should rapidly improve to VFR 15-16Z as the
front moves through the area. North winds could become gusty over
the Brush Country/Coastal Bend late morning into afternoon under
clear skies.
