Area Forecast Discussion
National Weather Service Brownsville TX
253 PM CDT Tue Oct 3 2017

...Beach tidal flooding high surf and dangerous rip currents
expected for most of this week...

.SHORT TERM (Now through Wednesday night):

In the near term (through or just after sunset) scattered to
numerous showers with perhaps a couple of rumbles in stronger
cells will continue to move steadily across Deep S. Texas and the
Rio Grande Valley with mainly welcome rain for many areas that
fell short in September...though there are pockets (e.g. Weslaco)
where minor nuisance flooding is possible where 2 to 3 inches of
rain fell late last week. Cells generally moving at around 20 mph
which keeps duration of heavy rainfall down to 10 minutes or so.
While some areas may see upwards of an inch, most areas under the
quick showers will see closer to 0.25 to 0.5 inches.

For tonight, well advertised pocket of mid level relatively dry air
thickens to the entire 700 to 500 mb layer.  With best upper level
forcing remaining south and actually dissipating into eastern
Mexico, expect coverage of rain to become more isolated after sunset
from east to west and could well end for a time in most inland areas
particularly between 10 AM and 4 AM, aided by diurnal downward
trends this time of year.  Toward daybreak the Gulf should light
up...some...and scattered showers likely to edge onshore toward
daybreak similar to this morning. Not seeing the big rain chances
advertised by guidance for the night as a whole and have cut back to
an overall "scattered" (30-50 percent) category with minor QPF as
well. Guidance appears to be hanging hat on deeper mean RH and
pocketed low QPF but sense of the weather will be more dry than wet
for most overnight.

For Wednesday, a more robust pocket of dry air...at least shown by
the GFS which has been fairly consistent over the past few
days...expands above 850 mb with flow turning northeast to northerly
(above 300 mb) in response to building upper level ridge and
subsidence circling clockwise around it. Morning scattered showers
near the coast should slide inland along with the remnant deeper
moisture but have tailed chances back considerably during the
afternoon from east of US 77 into the Gulf with no mention for the
beach after 4 PM. Once again, MOS guidance overplaying small
moisture details in light of the big picture, so "numerous" coverage
doesn't match and thus forecast is in line with scattered for most
areas. Nudged QPF down a little bit as well to be more in line with
lower areal averages.

The dry air mass strengthens a bit more Wednesday night, again due
to broadening ridge.  Low level moisture seems to thicken a bit but
it's hard to generate precipitation from lower moisture overnight
without heating...so once again have sharply dropped back on rain
chances with most areas dry until very late when the "flip" of
instability over the Gulf waters may get isolated pop up showers
going after 3 AM which should be able to reach shore before
daybreak...so have isolated wording for the beaches but just east of
populated US 77 corridor before sunrise.

As for the coastal flood situation:  Water indeed reached the edge
of the dunes at high tide earlier this afternoon, and with seas
building toward 9 feet already some 100 miles east of the 60 nm line
(Buoy 42020, adrift, was located due east of its normal position at
that location) and 20 to 25+ knot easterly gradient across the
length of the Gulf to continue through at least Thursday, along with
already 1.2 to 1.4 above predicted tides which are already near
astronomical levels, see no reason to wait for upgrade to advisory
and will issue on this package at 3 PM. At the same time, will add
Rip Current Statement and High Surf Advisory, triggering all of them
overnight but getting the word out for the late afternoon/early
evening news cycle. Will run through sunset Thursday as conditions
should easily reach into the dunes as predicted tides continue to
rise.

.LONG TERM (Thursday through Tuesday):

The upper level ridge will continue to build south and westward
through late week. Eventually our unidirectional easterly flow will
eventually transition to a northeasterly flow aloft. As the high
settles over or begins to build west, think that precipitation
chances will begin to drop Thursday and especially by this weekend.

Globals are coming into better agreement in terms of a tropical low
developing across portions for the far southern Gulf or western
Caribbean Sea late this week and into the weekend. The strongly
southwesterly sheared system should be picked up a an amplifying
trough across the central US. This should be enough to keep the
system well to our east.

As upper level subsidence/drying aloft occurs think that mostly
sunny to partly cloudy conditions can be expected. This should help
surface temperatures increase back into the lower to mid 90s with
the warmer locations being west of the I69C/HWY 281 corridor.

Although the low should remain well east of the RGV, there will be
continued increased swells and dangerous rip currents along area
beaches through early next week. Furthermore, as astronomical tides
continue to gradually increase through the week, coastal flooding
and beach erosion can't be ruled out in this scenario.

Early next week a ridge aloft will once again build across the
norther Gulf States. Overall, dry conditions can be expected,
however, with a southeasterly surface flow daily diurnal
shower/storm activity will be possible once again by Tuesday.

.MARINE:

Now through Wednesday night: Seas at the 42020 buoy, now located
between 130-160 miles east of Port Mansfield, have been flirting
with 9 feet today, and West Gulf buoy also in the 7.5+ foot range
as well. With swell likely to begin lapping or reaching into the
20-60 nm leg toward evening, will hoist Gulf Small Craft
Advisories with this package. Will use combined wind/sea advisory
to cover potential for 20-25 knot winds at times, and run through
Thursday sunset as well.

Otherwise, winds will generally range from 15 to 20 knots with
frequent 25 knot gusts especially Wednesday and Wednesday night over
the Gulf, and scattered showers will gradually become more isolated
moving into Wednesday afternoon and night.

For Laguna Madre, gusty afternoon winds may reach caution levels,
but for now will keep highlights out of forecast with main issue
this afternoon's remnant gusty showers and isolated to scattered
showers again on Wednesday.

Thursday through Sunday:

Easterly flow will continue across the northern Gulf through late
week, however, the fetch will eventually become disrupted due to the
possible tropical low in the central Gulf late this week or early
this weekend. That being said, depending on the strength of a
northward moving low pressure system (across the central Gulf),
there may be additional swells of 4-6ft going into the weekend, even
if surface winds are just a tad weaker. After the low pushes
northward our flow should eventually back to on offshore flow. Seas
will be moderated a tad when this occurs, however, expect swells to
continue in the 3-5ft plus range.  Small Craft Advisories will
possibly be needed through a good portion of the long term.
