A few lingering showers and maybe an isolated storm will continue
during the overnight hours before switching to land based showers
and storms in the afternoon once sea breeze action followed by
outflow boundaries starts to pick up. Deep moist air continues to
funnel into the area and will continue through for much of the
week from the gulf so storms will be very efficient rainmakers, so
a few spots could see some locally heavy rainfall especially
where stronger storms track or repeated rounds of storms go
through. There really isn`t a lot of wind support aloft so storms
will likely follow on the seabreeze/outflow boundary they are
before collapsing which cause some stalling in areas. For places
that don`t receive any or little rain from showers and storms will
see high temperatures slightly above the normal highs which is
currently forecast to be in the upper 80s to low 90s. Adding the
humidity will put the heat index values in the mid 90s to
threatening 100s especially this weekend.

.AVIATION...
(12Z TAF Issuance)
Issued at 557 AM CDT Thu Jun 4 2026

Mixed bag of IFR to VFR ceilings with the lower ceilings
currently near and north of the Houston metro area. Expect
IFR/MVFR ceilings to persist through at least the mid-morning
hours with the potential to stick around into the early afternoon
hours. SH/TS coverage will gradually increase throughout the day
with the greatest coverage expected to be around and south of the
Houston metro. Highest confidence window for TS is generally
between 17Z-22Z. Gusty winds and decreased visibilities/ceilings
are possible within any storms. Another round of TS is expected
late this evening into the overnight hours mainly south of I-10
and along the I-45 corridor. Timing for this convection is a bit
more uncertain, but generally looks to be after 06Z. Another round
of MVFR to IFR ceilings is anticipated overnight and into Friday
morning.

Easterly to southeasterly winds will prevail through the rest of
the week before turning more southerly around Saturday. Winds will
be elevated with periods of small craft exercise caution to small
craft advisory headlines will be likely needed at times. In
addition, due to the prolonged winds there may be increased waves,
rip currents, and slightly higher water levels during high tide
cycle.
