.SHORT TERM...
(This evening through Sunday Night)
Issued at 1227 PM CDT Sat Jun 7 2025

Hot, humid, and hazy conditions continue through the weekend as a
strong ridge of high pressure builds over South Texas. High
temperatures this afternoon will be rising into mid 90s for most
of the region, and then upper 80s along the coast with heat
indices in the 100-105 degree range. Tomorrow is shaping up to be
slightly warmer as hazy conditions begin to exit the region. High
temperatures will be rising into the mid to upper 90s inland, and
then upper 80s to low 90s along the coast. Heat indices will see a
similar slight uptick, into the 102-107 degree range, and we will
be borderline Heat Advisory conditions. Overnight temperatures
will be in the mid to upper 70s inland, and low 80s at the coast,
which is about 7-10 degrees above normal. Due to the fact we are
seeing these high temperatures this early in the summer season,
the experimental HeatRisk shows widespread Major impacts (level 3
of 4) for both today and tomorrow. This means that this level of
heat impacts anyone without effective cooling and/or adequate
hydration.

There may be a few isolated streamer showers across the area this
afternoon and Sunday afternoon producing a sprinkle here or
there, but generally the short term will be rain-free. There will
be a shortwave passing through the RRV Sunday evening into Sunday
night likely producing a cluster of thunderstorms. These
thunderstorms may live long enough to pass through the Piney Woods
late Sunday night into Monday morning. If these storms survive as
far south of the Piney Woods, there could be an isolated strong
thunderstorm. Rain chances increase for across the area heading
into the work week, but read more on that below.

.LONG TERM...
(Monday through next Friday)
Issued at 1227 PM CDT Sat Jun 7 2025

The upper-level ridge over Texas begins to break down and shift to
the west on Monday as a large upper level trough swings through
the Northern Plains/Great Lakes region. Weak shortwave troughs
moving around the edge of the large low will be swinging through
midweek before this upper level low exits to the east. Another
disturbance exits into the Southern Plains and continues eastward
beginning Wednesday and continuing through Friday. All this
messiness aloft will lead to continued rain chances through the
majority of the work week. The chance of showers and storms remain
greatest over the Piney Woods on Monday into Tuesday, but then
chances increase across the entire region by Wednesday through the
remainder of the period.

Conditions on Monday will still be hot and humid across the area
with highs in the 90s for most of the area. But with increasing
rain chances and cloud cover, temperatures begin to fall back
closer to normal by midweek with highs in the upper 80s to low
90s. However, the increased cloud cover will also keep the area
well insulated at night keeping the overnight temperatures above
normal: mid to upper 70s inland, low 80s at the coast.

.AVIATION...
(00Z TAF Issuance)
Issued at 608 PM CDT Sat Jun 7 2025

Gusty windy late this afternoon should subside this evening with
lighter winds prevailing thereafter. Cloud decks around 1500-3000
ft will develop tonight. These decks may fill in at times to bring
MVFR conditions, especially across the northern terminals during
the early morning hours of Sunday. Patchy fog will also be
possible during this period of the forecast. After sunrise, expect
all fog & CIGS to clear out as winds & gusts pick up once again.

.MARINE...
Issued at 1227 PM CDT Sat Jun 7 2025

Onshore flow will persist through at least mid-week next week with
speeds around 10-15kts during the day, increasing to 17-19kt and
occasional higher gusts during the overnight periods. Small craft
may need to exercise caution at times due to these breezy conditions.
Seas will generally be 2-4ft near shore, and 3-5ft off shore
through next week as well. Rain chances return by Tuesday with
continued chances through the remainder of the week.

The persistent onshore flow may result in an increase risk of
strong rip currents beginning tomorrow.
