Marine Weather and Tides
Corpus Christi, TX

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Discussion
Allowed high risk of rip currents to expire, but will maintain a
moderate risk for the gulf facing beaches through Thursday.

Updated aviation discussion for the 06z tafs.

Aviation
Tropical moisture will continue to linger across south texas for
a majority of the period. Ceilings will be predominantly MVFR, but
with any shower activity, CIGS and visibility could lower to ifr
and briefly to lifr at times. Although the 00z sounding is a bit
drier than last night, pwats are still in the realm of 2.35
inches. So still expecting a some showers associated with a
surface low to affect mainly the ali and crp area early this
morning.

Current radar trends has some lighter showers across the brush
country, but with the low center shifting a bit more westward,
thinking some light showers could possibly make it to the lrd area
a bit later this morning, therefore have included vcsh.

Otherwise, the majority of showers are offshore and making their
way into the northern coastal bend. Could see some of light showers
make their way into vct area, but confidence is not too high
given the more stable environment. Additionally, some development
on the western edge of the main offshore cluster and development
further south of baffin bay is likely fill in and make its way
into crp area, resulting in light to moderate rainfall through the
morning. Some additional development south of ali may continue to
form and make its way around ali as well early this morning.

Although, not as active as the previous day, will still maintain
some shower activity through at least the late morning hours across
the eastern terminals, but expecting the shower activity to
decrease towards the afternoon evening.

Previous discussion issued 408 pm cdt Wed jun 20 2018
short term (tonight)...

showers and thunderstorms have been ongoing for most of the
day across south texas. The heaviest rainbands set up along
the coastal bend this morning where we saw rainfall rates of
2-4" per hour resulting in multiple flash flood warnings and a
flash flood emergency for port aransas. We have seen 5-10" fairly
widespread across eastern portions of the CWA with pockets of
rainfall approaching 15". Activity waned a bit this afternoon but
has recently begun to redevelop across the brush county and over
the gulf waters where there has been a few breaks in the clouds.

Expect showers and thunderstorms to continue through the evening
with potential for another round of heavy rainfall early
tomorrow, although this will not be as strong as what we have seen
the last couple of nights. H85 moisture transport remains
efficient through the period with an area of low level moisture
convergence setting up along the coast tonight early tomorrow
morning that will cause the uptick in activity. We are looking
at the potential for an additional 1-3" tonight through tomorrow
afternoon. Any additional rainfall will quickly lead to flash
flooding.

Low temps will be right around average tonight with lows in the
mid 70s out west to the low 80s along the coast.

Long term (Thursday through Wednesday)...

although the mid level low is expected to drift southwest into
mexico Thursday, a mid level trough axis will extend to the
northeast across coastal plains Thursday morning and slide to the
west into the brush country during the afternoon. Moisture levels
will not be near record values on Thursday but will still be plenty
high with precipitable water values from 2.3 to 2.5 inches during
the morning hours. Expect scattered showers isolated thunderstorms
to occur in convergence axis near the coastal plains on Thursday
morning with activity moving inland into the brush country in the
afternoon. Will continue with likely pops for the coastal areas
Thursday morning. Showers and storms will be capable of producing 2
to 3 inches per hour. Any rainfall over saturated grounds would lead
to flooding, so the flash flood watch has been extended to 18z
Thursday.

Rain chances will quickly diminish to only a slight chance over
southern areas for Thursday night as the mid level trough axis
continues to move southwest into mexico and moisture decreases over
the area. Will hold on to slight chance pops over the coastal areas
on Friday for possible isolated activity. An upper level ridge will
build into the region Friday into Saturday with temperatures back to
slightly above normal levels. An area of low pressure will form over
the central high plains on Saturday in advance of a weak short wave
trough. This will lead to an increase in onshore flow with winds
approaching SCA levels at times over the weekend. The ridge will
weaken by Sunday with an inverted mid level trough axis moving into
south texas. Enough moisture will arrive by Sunday for slight chance
pops. Better moisture will be in place by early next week for Monday
into Tuesday as the mid level trough axis moves inland. Will show
low end chance pops for the coastal bend Monday and Tuesday. Rain
chances will decrease slightly for Wednesday as the mid level trough
axis moves away from the region and an upper ridge builds back.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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.
