The episode as NWS HGX wrote it up.
Favorable upper levels, with a western U.S. low positioning itself off to the southwest, and decent lower level inflow of high moisture lead to an environment conducive to thunderstorms. These clustering storms produced localized high rainfall rates that lead to flooding.
The local office's own words before the first event, 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 the first event at Jun 2, 5:24 PM CST, 6 minutes earlier.
Area Forecast Discussion
National Weather Service Houston/Galveston TX
624 PM CDT THU JUN 2 2016
.AVIATION...
The upper low was nearing Hondo at 6 pm, and should continue
meandering slowly eastward. This will keep the terminal sites
under favorable airmass for shower and thunderstorm development
through the next 24 hours.
Most confident with the first 4 to 6 hours. Area of moisture
convergence will keep storms over KIAH, KHOU, and KSGR through at
least mid evening. Also expect KLBX, KGLS, and KCXO to have good
chances for thunderstorms.
Most areas will likely see another round of storms overnight
tonight and then Friday afternoon.
Expect IFR to MVFR conditions in the areas of storms through the
period.

.PREV DISCUSSION... /ISSUED 345 PM CDT THU JUN 2 2016/
DISCUSSION...
Flash flood watch extended through Saturday afternoon.
Upper low spinning away west of SAT with s/w reaching CRP to EWX
at 20z. Scattered showers and thunderstorms developing across the
area forming small lines and moving northeast with the mean
7-500mb flow. Belt of convergence seen in the observations from
near SAT to Eagle Lake to Houston to Groveton and this should be
active area through early evening. A second area will likely
develop close to the coast and over the Gulf waters as s/w tracks
across the area this evening. Will be keeping an eye on the upper
low track as it nears the area toward morning and may undergo a
warm core rain event...that would probably only impact the NW
counties.
The region remains in a very favorable area for showers and
thunderstorms with heavy rainfall Friday as upper low stalls and
begins to retrograde while filling. Low level flow backs slightly
and the region will probably see scattered to numerous showers and
thunderstorms Friday and late Friday night/Saturday morning.
Frontal boundary sagging south Saturday through the area will also
probably become a focus for showers and thunderstorms with
widespread coverage. Overall widespread 2 to 3 inches amount with
localized areas of 4 to 8 inches will be possible. If a warm core
event evolves then the rainfall totals will likely need to be
adjusted upwards. Still to early to pinpoint if that scenario will
develop over the area though.
Dry air spreads into the region from the north Sunday and rain
chances should taper off quickly from north to south and by Monday
afternoon will only carry 20 pops for the coast in deference to
the ECMWF. Monday through Wednesday may be relatively dry.

MARINE...
The thunderstorm complex that has been moving across the coastal
waters for much of the day has all but shifted east of the Upper
Texas coast this afternoon. However, additional showers and
thunderstorms are expected in the wake of this line this afternoon
and evening as a disturbance pushes northeast out of South Texas and
already seeing some development occurring along the Texas Coastal
Bend. With the main upper level storm system that is responsible for
this activity hanging up over Texas, periods of showers and
thunderstorms are expected through the remainder of the weekend as
additional disturbances approach the coastal waters. Locally higher
winds and waves will be possible in any thunderstorm activity, as
well as visibilities reduced to 1 NM or less. Improving conditions
are expected by the end of the weekend as a weak cold front
approaches into the coastal waters, with light offshore flow
persisting into the beginning of next week.
