Synopsis for the middle texas coastal waters.. A generally moderate onshore flow is expected over the middle texas coastal waters tonight through Saturday night...as high pressure remains over the northeast gulf of mexico and low pressure is over northwest texas. Onshore flow will become weak to moderate Sunday and Monday as a weak frontal boundary gradually pushes south toward south texas. The front will stall before reaching the coastal waters. Shower and Thunderstorm chances increase by early next week as moisture pools along the boundary.

area forecast discussion... Updated
national weather service corpus christi tx
653 pm cdt Fri may 26 2017

Discussion Downward trend in heat index values continue and
will be below advisory criteria for rest of this evening. Will
allow heat advisory to expire. See aviation section for 00z tafs.

Aviation Satellite imagery shows a band of MVFR ceilings
persisting from north of corpus christi bay to the mid-coast
region. Expect these lower ceilings will continue for this area
and impact vct through the early evening hours. Elsewhere,VFR
conditions are expected early this evening. Stratus deck expected
to affect all of the coastal plains by 03z with MVFR conditions.

Depth of moisture layer near the surface is expected to decrease
through the night as drier air at the 2-3 kft layer. Ceilings
could lower to near ifr levels along with MVFR vsbys with fog
over the victoria crossroads but kept prevailing ceilings at MVFR
through the night for coastal sites. MVFR ceilings could reach lrd
between 11-15z. With influx of drier air at low levels, expect
improvement toVFR will be faster than today. Kept tempo group for
MVFR ceilings at ali crp from 14-16z and vct from 15-17z Saturday.

South winds will become gusty by mid morning over the coastal
plains and increase further to the southeast in the afternoon.

short term (tonight through Saturday night)...

main issue is the heat and humidity, not only for the remainder of
the afternoon but also on Saturday, as a very humid airmass is in
place over south texas. Temperatures over the western areas have
been slow to rise today, but clearing skies should bring
temperatures up enough with the high dew points to bring heat
indices apparent temperatures to near or above advisory levels over
the advisory area. Heat index tool and MAX hi grid is showing aoa
109f over the advisory area. Thus, it would be foolish to adjust the
advisory now as most areas which do not get to 110f for a couple of
hours will get rather close (at least close enough to keep it
going).

Another warm and humid night with similar overnight temperatures.

Lows may be a degree or so cooler in some spots since the winds will
not stay up, although another low level jet will be in place over
the eastern portions of the forecast area. On Saturday, it looks
like heat advisory criterion will be isolated at best (at least
according to the grids), so will likely need a sps for Saturday.

Drier air will push in on Saturday as well, helping to mix out
moisture a bit more (and bring more Sun than clouds). As a result,
we will see temperatures perhaps a degree or two warmer than today.

Another warm and humid night Saturday night, and temperatures and or
overnight lows will not sway far from persistence. Moisture still
looks limited and although upper level flow remains wsw, cap is
strong and any weak disturbances will not be enough to warrant a
mention of rainfall at this time.

Marine (tonight through Saturday night)...

winds are expected to remain below sca, with scec conditions over
the southern bays and gulf waters this evening and tonight,
respectively, then again Saturday afternoon and evening night
respectively. No rain in the forecast, although we could have some
showers late Saturday night as cap over the gulf of mexico weakens
and there is some moisture convergence. For now, persistence
forecast for convection seems to be the way to go.

Long term (Sunday through Friday)...

at the onset of long term period cold front will be drifting
southward through texas wile upper level trough shifts eastward from
the rockies. With energy associated with the trough remaining well
north of the region front will have little push to keep it moving
south. Models have been consistent in stalling the front near or
over the forecast area. Expect only a shift in winds to the east at
best. This front however will provide a focus for shower and
thunderstorm activity beginning Sunday night. Abundant moisture
across the region with precipitable water values likely in excess of
two inches will lead to the potential for moderate rain across the
region. Rainfall totals could be as much as 2 to 3 inches in some
areas over the holiday weekend. Rain chances will continue through
at least the middle of the week as weak upper disturbances traverse
around the trough to our north. Best chance for rain in the period
will be late Sunday night through Monday night. Main upper support
being north of the area, expect a minimal threat for severe weather.

Locally heavy rains will be the main concern with the possibility
of rather slow storm motion.

Temperatures Sunday remain hot with highs mainly in the 90s to
around 100 west. By Monday with the front lingering in the region,
expected rainfall and cloud cover, will see somewhat cooler
temperatures with highs in the 80s. Gradually warming temperatures
are then expected later next week. Low temperatures remain in the
70s through the period.

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.
