Synopsis for the middle texas coastal waters.. Areas of dense fog will continue to develop through the night, but conditions may improve some towards Sunrise. Moderate onshore flow is expected to develop overnight and continue on Saturday. Winds could approach small craft advisory levels toward morning. Another cold front will move into the coastal waters late Saturday night into Sunday resulting in a weak to occasionally moderate offshore flow in the wake of the front. Scattered to numerous showers and isolated Thunderstorms are expected with the front. Drier air will move in Sunday night, diminishing the chances for rain. A weak to moderate northeast flow is expected Monday. A return of onshore flow will occur Monday night as high pressure moves to the east. Onshore flow will increase to moderate levels Tuesday into Wednesday as low pressure develops over the southern high plains.

area forecast discussion... Updated
national weather service corpus christi tx
908 pm cst Fri feb 23 2018

Discussion As of writing, a quasistationary boundary was
draped from north to south from near kcot to just east of klrd.

Areas of fog and drizzle were persisting to the west of the front
(with dense fog impacting laredo) while improved visibilities
existed east of the front. Farther east along the middle texas
coast, stratus was lowering and thickening with sea fog developing
along and just offshore.

Due to the fluctuation of the aforementioned boundary, several
changes have been made to the inherited forecast. Bumped min temps
down a few degrees across the W brush country due to the boundary
having shifted back east. Still think the boundary will shift
farther west again late in the night which should result in an
increase in temps at that time. Also added mention of fog for this
evening (and continuing overnight) for the brush country.

With a weak mid level vort MAX prog to shift NE overnight out of
mx (partially evident on GOES 16 WV analysis and latest rap
output), chances of convection may increase overnight for the
brush country. Convection is already ongoing across nuevo leon
with some guidance (nam GFS hrrr) hinting at some potential for
convection to develop across the brush country after midnight. I
have chosen to expand the chance pops a little farther south with
this update given that the current position of the vort max.

No other changes made to the land forecast at this time. A
southerly LLJ of 40 to 45 kts is prog to develop across much of
the CWA overnight, which should allow for breezy conditions to
continue and stratus to thicken. Temps should fall very little
from current values (for those areas east of the surface front).

Marine Have issued a marine dense fog advisory for area bays
and the adjacent nearshore waters. Fog should continue to expand
in coverage overnight as moisture values increase. However, by
late in the night the wind direction from port aransas southward
may become more southerly, which may allow for visibilities to
improve some (at least for a couple of miles). Farther north, fog
is likely to persist through mid morning.
