What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Houston/Galveston, TX wrote its last area forecast discussion before this river flood warning went out at May 12, 6:29 AM CDT, 2 hours 54 minutes earlier.

Area forecast discussion, May 12, 6:29 AM CDT, 2 hours 54 minutes before
Area Forecast Discussion
National Weather Service Houston/Galveston TX
629 AM CDT Wed May 12 2021

.AVIATION [12Z TAF Issuance]...

Storms have pushed off the coast, but still a tricky forecast this
cycle. Some showers may crop up yet this morning into the
afternoon, but primary impact will be CIGs. High IFR/Low MVFR now,
should see slow, gradual rise in stratus bases to high MVFR/low
VFR along with gusty NNE winds. This evening, winds veer just a
bit to more northeasterly and decrease in speed. Unclear how deep
incoming dry air will be, so play it safe for now and bring back
MVFR stratus overnight.

&&

.PREV DISCUSSION /Issued 357 AM CDT Wed May 12 2021/...

.DISCUSSION...

Rain showers have not yet come to an end across Southeast Texas,
but their intensity has waned some early this morning, with
rainfall rates so far staying at or below half an inch per hour.
Because of this, we have canceled the flash flood watch for
Houston, Trinity, and Polk counties.

As lift along the frontal surface aloft will still be able to
manage some elevated convection, we can expect showers and storms
to continue into today, but gradually wind down - coming to an end
from northwest to southeast this afternoon into the early evening.
We can expect fairer weather to prevail until the end of the week,
when another front makes its way into the region. This will
provide us with another opportunity for showers and thunderstorms.
Like this past front, there is a strong potential for this front
to stall and only slowly make its way through the area, dragging
out potential rain chances deep into next week.

.SHORT TERM [Through Thursday Night]...

Water vapor and upper air analysis suggest a couple very subtle
shortwave troughs will be passing overhead. On top of that, we can
see additional support for upward motion thanks to divergence
aloft in the right entrance region of the exiting upper jet.
Despite the surface front itself, these lingering supporting
features are likely helping to drive a handful of showers across
the area very early this morning - and until these disturbances
move off, the jet streak exits stage right, and the frontal
surface just aloft follows its surface accompaniment offshore, we
shouldn't expect rain to be totally over - just mostly over.

That said, new HRRR data is coming in pretty dry, with barely
anything to speak of for rainfall after 12Z. I've chosen to be a
little bit conservative and drag slight chance to chance PoPs out
through the afternoon for most to give everything a chance to
clear out and have deeper offshore flow set up to scour out the
last remnants of this event. Besides - in a situation in which
convection allowing models have not performed terribly well, I'm
not too excited to put a lot of stock in a deterministic model
run. The 00Z HREF still suggests a parting shot of rain, locally
heavy, late this morning along the coast before rain totally
comes to an end. I can't say I necessarily buy this fully either,
but it does highlight the breadth of possibilities and amount of
disagreement in the models for just the next several hours.

Given that current activity isn't super intimidating, I tend to
favor a continuation of that through much of the day. By mid-day
up north around B/CS and Madisonville, and by evening at the
coast, things should be pretty much done. Modestly drier and
cooler air looks to filter in tonight, letting at least the inland
portion of the area get pleasantly cool. Things will be iffier as
you get coastward, and down here in Galveston County, I am
resigned to missing out on most of the nice dry air.

Thursday will see the return of high pressure and a clearing sky
from north to south, allowing the return of fair weather. Of
course, given the lack of cold advection and a clear sky in mid-
May...expect temperatures to bounce right back into the 70s across
Southeast Texas, and threatening 80 degree highs in the coastal
plain. Sorry, y'all.

.LONG TERM [Friday Through Wednesday]...

The surface high pressure will begin to slide to the east on Friday
and onshore flow will return by the evening. This will help to
increase temperatures and moisture through the weekend. Daytime
highs will remain in the 80s, but overnight lows will creep back
into the 70s by Sunday night.

By Saturday and Sunday, an upper-level low over the Pacific
Northwest will push south and is expected to become a cutoff low
over California as the jet stream splits. Meanwhile, Central CONUS
will be in a broad ridge and wedged between another upper-level
trough over the Mid-Atlantic. Global models show a weak
trough/shortwave developing in the broad ridge over the Central US
with a low pressure trying to develop over the Central Plains and a
messy cold front stretching as far south as the Gulf Coast.
Therefore, rain chances will begin to increase on Sunday as this
front approaches from the west. As the front loses upper-level
support from the jet stream and the upper-level flow becomes more
zonal, models disagree on how to treat this front Monday onwards.
However, most global models and blends still show rain chances
continuing through midweek next week. Therefore, generic PoPs (20-
30%) are predicted for Monday onwards until models come to more of a
consensus.

.MARINE...

Rain chances will continue through tonight as a stationary front is
expected to push into our coastal waters and exit the region.
Today, post-frontal winds will become NE and increase to at least
SCEC criteria and hover near SCA criteria. NE-E winds will
persist through Friday afternoon until the surface high pressure
overhead pushes east. By Friday evening, onshore winds resume and
are expected to increase to SCEC or SCA criteria by Saturday
evening as another front approaches our region. This onshore wind
will persist through midweek next week. Rain chances also increase
again on Saturday through midweek next week due to this front.

.HYDROLOGY...

Most area rivers are handling the area's recent rainfall very
easily as widespread amounts have not been exceptionally high.
However, the Trinity River watershed has been an exception, which
has seen the brunt of each successive day's rainiest storms. River
levels are rising in response, and forecasts now take the Trinity
River at Riverside above flood stage late this afternoon or early
this evening. A flood warning has been issued.

At this time, Riverside is the only location expected to reach
flood stage and rain will be winding down today. Locations further
down the Trinity River, such as Liberty and Moss Bluff, may have
to be watched closer to the weekend - but river levels there will
be partially influenced by releases from Lake Livingston in the
coming days.
