A moderate to strong offshore flow will develop late Tuesday night into Wednesday as a cold front and associated surge of surface high pressure moves across the coastal waters.

740 am cst Mon nov 20 2017

Discussion Short wave trough moving through south texas early
this morning. 12z crp sounding showed steep mid level lapse rates
with adequate mid level moisture. Isolated thunderstorms moving
across the southern coastal bend will continue to move east into
the coastal waters this morning. Even had report of small hail
with thunderstorm near orange grove. Updated forecast to include
mention of isolated thunderstorms for the southern coastal bend
and coastal waters this morning. Short wave trough will move east
of the region by this afternoon with only lingering slight chance
of rain over the offshore waters.

Previous discussion issued 537 am cst Mon nov 20 2017
discussion...

some enhanced echoes showing up out to the west with tops around
30 kft. Still looks as if most of this will not reach the ground,
and even if it does we should see no more than trace amounts. In
short, did include sprinkles over inland areas for this morning.

Updated products out.

See .Aviation discussion for 12z tafs.

Aviation...

vfr conditions with light winds. Could have a gust or two this
morning as enhanced reflectivity could bring some higher momentum
winds down. Could also have a sprinkle or two mainly kali and kcrp
but did not include at this time as this will be rather brief.

Winds shift to the SE from west to east today, with light winds
developing this evening and overnight. Some fog possible at kvct
and kali toward morning. For now, just going MVFR and ifr at each
location, respectively.

short term (today through Tuesday)...

water vapor imagery and streamline analysis is showing trough just
east of the big bend region moving slowly eastward. Some mid and
high clouds are showing up on the IR channel, and the evening
sounding showed a rather dry airmass 700mb and below. Model
guidance for rainfall seems once again to be keying on the high
mid and upper level moisture which is expected to decrease later
this afternoon (and maybe earlier) as south texas begins to get on
the back side of the upper trough. In short, will go with a dry
forecast for today (except offshore) as expect any rain which
falls from the mid and upper cloud cover will evaporate before
reaching the ground (could not rule out a drop or two on the
windshield this morning). Looking at the water vapor imagery, it
looks as if the better moisture is already beginning to push east.

Otherwise, return flow resumes today and does not become very strong
through Tuesday, perhaps being a bit ssw on Tuesday ahead of the
next frontal boundary. Moisture does get better by Tuesday afternoon
and there is a pretty potent upper level jet which approaches the
area Tuesday afternoon, but it looks like the better dynamics (and
moisture) may be more east of the inland areas (maybe near the coast
late Tuesday afternoon). In any case, will keep the forecast over
inland areas dry for now. Mid level moisture moisture advection is
not impressive on Tuesday so will hold off on rain except offshore.

Warmer each period, with the better warm-up on Tuesday with the weak
westerly flow in the boundary layer. Generally went on the warm side
of guidance for highs. For Tuesday morning lows, went near or cooler
than MOS away from the coast but near or on the warm side closer to
the coast.

Marine (today through Tuesday)...

onshore flow returns, and with the upper trough impacting the waters
could not rule out a sprinkle or two. However, patchy rain (to where
it would be significant enough) is a bit over-done and thus will
just mention sprinkles for today. For Tuesday, there could be enough
jet dynamics along with instability for some showers in the
afternoon. Could not rule out thunder, but for now will just keep it
showers. No other marine issues at this time.

Long term (Tuesday night through Sunday)...

models prog another cold front to push through S tx Tuesday night in
response to a long wave trough aloft moving SE across the region.

Sufficient moisture is progged to be in place across the eastern cwa
and over the gulf waters ahead of and along the frontal bdry to
produce iso sct -shras. Am not expecting tsras due to low cape
values and drier airmass above 700mb along with a cap, thus
hindering deep convection. Advisory conditions are anticipated
across the coastal waters late Tue night into Wed behind the front.

Drier and cooler conditions will filter across S tx through Wed with
lows Wed night in the 40s most locations. Thanksgiving day is
expected to be pleasant with abundant sunshine, light winds and
temps in the 70s. Onshore flow resumes Thu with a warming trend
fri Sat ahead of the next cold front. Models have been inconsistent
with next weekends front and now show a very weak front with winds
backing to the east and northeast by late Sat night or Sunday
morning with temps only slightly cooler in its wake. Moisture will
be limited, therefore no significant rainfall is anticipated next
weekend.

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.
