Synopsis for the middle texas coastal waters.. Isolated to scattered showers and Thunderstorms are expected into the weekend, with most of the rainfall activity occurring this weekend during the overnight and morning time frames. Weak to moderate onshore flow will persist today through next week. Rain chances will increase by early next week as an upper level disturbance moves north of the area and frontal boundary sinks southward across the state.

area forecast discussion... Updated
national weather service corpus christi tx
708 pm cdt Fri sep 22 2017

Discussion Isolated convection will continue for another hour
or two over the western brush country. Will update forecast to
include mention of isolated storms early this evening. See
aviation section for 00z tafs.

Aviation Vfr conditions will continue into the early overnight
hours except for the next couple of hours over the western brush
country where isolated convection will provide MVFR vsbys. Light
winds and high boundary layer moisture will lead to patchy fog
over the inland coastal plains from 09z until 14z. Fog may get
worse in the vct area with possibility of ifr vsbys. GOES 16 image
of precipitable water shows an axis of higher moisture over the
gulf into the coastal bend. With adequately steep low level lapse
rates, should see isolated streamer showers along the coast into
the crp area Saturday morning. MVFR ceilings will become prevalent
over the southern coastal bend and continue into early afternoon
with isolated showers and thunderstorms moving inland with the sea
breeze boundary. MVFR ceilings will develop around 08z for the lrd
area and continue until late morning.VFR conditions will be
prevalent for the afternoon except for MVFR vsbys within isolated
convection.

Previous discussion issued 324 pm cdt Fri sep 22 2017
short term (tonight through Saturday night)...

not much change in the weather pattern and or airmass ergo not much
change in the forecast for these periods. The upper ridge is
blocking the western trough from making any eastward progress but the
trough to the east is not moving much either. Thus the area is stuck
in a similar airmass with only subtle differences in moisture. With
no significant changes in winds (higher or lower), pretty much will
continue to go with 10 to 30 pops for Saturday, with rain chances
toward morning near the coast with the coastal convergence
showers possible thunderstorms. Will play the same slightly higher
chance for rain Saturday over the NE in the morning pushing NW in
the afternoon, with slight chance other locations again along the
weak sea-breeze. Rain should taper off again by early evening with
another round of rain possible near the coast toward Sunday morning.

Overnight lows a blend of mosguide and previous forecast. For highs
on Saturday, mainly used a blend of bias-corrected blended model and
previous forecast.

Marine (tonight through Saturday night)...

generally weak to near moderate flow through Saturday night, with
showers possible thunder developing again overnight especially near
the coast then tapering off in the afternoon with the weak sea-
breeze.

Long term (Sunday through Friday)...

overall pattern in the long term period remains the same, but
wavering a bit on confidence with rain chances latter half of the
period. While moisture will most likely be plentiful, upper support
is questionable. Latest model runs cut off an upper level low
earlier than previous runs, causing upper trough to tilt back to the
southwest and not progress toward texas. This could result in
ridging remaining over the eastern portion of the forecast area with
some of the upper level energy over western portions of the area. As
we're still talking about days 4 and 5 will continue to broad-brush
a chance pop area wide until the finer details can be ironed out.

Regardless of the upper support, the moisture and sea breeze should
be enough to give us at least some convection daily. Will expect
abundant clouds through much of the period as well. As for the
potential for a cold front late in the week, still plenty of
question with that and tilting of the upper level trough could rob a
lot of the energy necessary to pull the front this far south. If it
does make it through, dont think we're looking at anything game
changing. A shift to an east or northeast wind and temperatures
maybe a few degrees cooler... But again... It's a long way down the
road and still lots of questions.

Temperatures should see a very gradual decline through the period
with highs in the low to mid 90s early, dropping into the upper 80s
and lower 90s as moisture increases. Lows remain mainly in the 70s.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
