Discussion
For 18z TAF issuance.

Aviation
Local 88ds show the large rain shield covering the forecast area
beginning to break up somewhat while a few embedded storms try to
get going. Followed the latest hrrr runs in the short-term as far
as precip coverage goes... Showing a diminishing trend next few
hours before a more enhanced line develops and pushes across the
region later this afternoon into evening. Sfc obs show much lower
ceilings north of the frontal boundary hugging the coastline at
this time... And latest progs show the front maybe drifting farther
inland over acadiana next few hours. After sunset expect ceilings
to lower once again with nrly winds eventually developing behind
passing sfc low... While rainfall becomes much more widespread.

Expect conditions to improve somewhat after sunrise Tuesday.

update...

regional radar activity shows widespread light to moderate rain
ongoing across the region with isolated thunderstorms. An MCV can
be noted in the regional radar imagery SW of houston and is
progressing to the ene along and south of the surface stationary
boundary over the gulf coast. Rainfall coverage and intensity will
likely increase ahead of the MCV as it progresses along the gulf
coast. Overall, the forecast for the rest of today remains on
track with a widespread 2 to 4 inches of rainfall expected with
locally higher amounts. Some localized flash flooding is still a
concern and the flash flood watch remains in effect until late
tonight. Additionally, a few minor adjustments were made to the
pops later this evening and overnight tonight corresponding with
lower QPF across interior southeast texas and southwest louisiana
tonight.

Marine...

marine observations this morning have shown sustained winds near
20 knots with higher gusts near houston in closer vicinity to the
surface low. As the low moves eastward, winds are forecast to
increase over the coastal waters to near 20 knots. This morning's
forecast update increased forecast winds over the coastal waters
through the evening hours. Small craft exercise caution conditions
will be prevalent through late tonight and conditions may
approach small craft advisory criteria occasionally.

Prev discussion... /issued 651 am cdt Mon may 22 2017/
aviation... Increasing shower and thunderstorm activity can be
expected through the day. This as stationary front remains draped
along the coast, and disturbances move through a westerly flow
aloft. Some of the storms could produce strong wind gusts.

Otherwise, look for MVFR ceilings to prevail, slipping down into
ifr overnight as convection tapers off.

discussion...

rains are continuing this morning along a stalled frontal boundary
that extends from the central texas coast into eastern louisiana.

The overnight rain complex over southwest louisiana is exiting
into eastern louisiana ATTM while the next round of rains is
forming southwest of houston. This area will lift to the northeast
through the morning hours. With all the storms expected today the
potential for severe will remain limited but the flash flooding
threat will continue as two to three inches are expected with
some locations mainly in south central louisiana receiving upwards
to six inches in isolated amounts. Due to the recent rains most
of the rains are expected to run into the bayous and ditches with
minor flooding expected again. Temps into the upper 70s today as
clouds and rains will cool the atmosphere.

Rains are expected to taper off this evening into the overnight
hours as the stalled frontal boundary drifts back into the coastal
waters. A second stronger cold front will whip around the
backside of the sfc low over the upper plain states this am and
run towards the gulf coast this evening. This next front looks to
push the stalled boundary off to the east Tuesday evening with
rains tapering off slowly. The early morning hours on Wednesday
rains will have ended with morning lows back into the lower 60s.

We are expecting a brief cool spell but afternoon temperatures and
humidity will return over the weekend.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
