.SHORT TERM...
(Tonight through Saturday night)
Issued at 1224 PM CDT Fri Jun 6 2025

Hot and humid conditions are expected for Deep South Texas tomorrow,
as upper level ridging and southeasterly surface flow persists over
the region. This poses a moderate heat risk throughout the area due
to hot temperatures combined with even hotter apparent temperatures.
High temperatures are expected to be in the upper 90s/lower 100s,
but apparent temperatures (what it actually feels like outside)
could be as high as 110.  Little to no precipitation is expected,
along with mostly sunny to partly cloudy skies and southeasterly
winds. Low temperatures for both tonight and tomorrow should be in
the upper 70s/lower 80s.

.LONG TERM...
(Sunday through next Friday)
Issued at 1224 PM CDT Fri Jun 6 2025

Hot, humid, and precipitation-free conditions are expected to
continue through the weekend into early next week as upper level
ridging continues and surface winds remain southeasterly. On
Tuesday, a shortwave moves over the area and a frontal boundary with
a surface low moves from North Texas into Central Texas, ultimately
stalling over South Texas by Wednesday. This will increase chances
for precipitation in Deep South Texas beginning Tuesday (around
20%), with the greatest chances (approximately 30-50%) being on
Wednesday. Chances should slightly decrease to around 20-30% on
Thursday and Friday, mainly east of I-69E near the coast due to sea
breeze activity.

Temperatures are expected to reach the upper 90s/lower 100s with
potential heat risk concerns through the start of next week. The
frontal boundary should help lower high temperatures into the mid-
90s due to increased cloud cover and potential precipitation.
However, low temperatures are expected to remain fairly consistent,
getting down into the upper 70s/lower 80s each night throughout the
forecast period.  Winds should also remain southeasterly and
generally light to moderate throughout the entire forecast period.

.AVIATION...
(18Z TAFS)
Issued at 1224 PM CDT Fri Jun 6 2025

VFR conditions are expected throughout the TAF period at all
airports. Winds will be moderate and southeasterly, potentially
becoming gusty after 23z.

&&

.MARINE...
Issued at 1224 PM CDT Fri Jun 6 2025

Small Craft Exercise Caution conditions are possible over the next
several days due to increased windspeeds (possibly over 15 knots)
over the Gulf waters.  These should gradually decrease Tuesday into
Wednesday of next week, making marine conditions slightly more
favorable.  Wave heights should generally be between 3 and 5 feet
through the duration of the forecast period, and winds are expected
to remain southeasterly.
