.DISCUSSION...
Issued at 1250 AM CDT Mon Jun 8 2026

Subtropical jet over the area will gradually weaken as upper level
ridging from the west slowly pushes in. Moisture from the gulf
continues to keep the PWs in the area relatively high at or just
above 2 inches. Today is probably the best chances of any showers
being right now to the early morning hours along the coast, then
another chance of showers and storms in the afternoon hours. There
is still a limited chance of some heavy rainfall in the stronger
storms leading to street flooding in areas that have had repeated
rounds of rain but the threat seems relatively minimal compared to
the previous days. High pressure from the gulf will slowly move in
and help suppress but not completely remove chances of
convection. However since there will be less rain and cloud cover,
high temperatures will climb from the upper 80s to low 90s to the
low to mid 90s as the week progresses, with heat index values
reaching the mid to upper 100s by late this week.

High risk of rip currents still remain a concern as persistent
onshore winds continues, however the winds will begin to decrease
later this week which will help decrease it down to more of a
moderate risk.

.AVIATION...
(12Z TAF Issuance)
Issued at 525 AM CDT Mon Jun 8 2026

Prevailing MVFR ceilings at most terminals this morning with
isolated pockets of IFR ceilings. Expect ceilings to improve to
VFR by the late morning hours. A band of lingering light rain
along and south of the I-10 corridor is anticipated to persist
through most of the morning hours before gradually dissipating. In
the early afternoon, there is potential for isolated thunderstorms
to develop mainly north of I-10. Confidence is not high enough to
include any thunder in this set of TAFs, but did include some
PROB30`s for SHRA as greatest confidence on afternoon activity is
CXO and northward. Winds will be southeasterly around 10-15 kt
with gusts up to 18-23 kt at times through the afternoon. Any
lingering rain will dissipate around 00Z with MVFR to IFR ceilings
filtering in again overnight into Tuesday morning.

Southerly to southeasterly winds will persist for the week, with
winds dipping in and out of small craft exercise caution
criteria. Current flags will remains until later this morning.
Winds will then stay in the 10 to 15 knot range with the next
chance of flags being needed again being around mid week. Isolated
showers and storms are still possible but chances will decrease
slightly as the week goes on.
