.DISCUSSION...
Issued at 1250 PM CDT Sun Jun 7 2026

A pattern change is starting to settle in as upper level closed
low around the Texas Panhandle moves northeast into the Great
Plains and weak ridging start building into Texas. While this will
help decrease the chances of showers and storms and generally
limit it to the more typical seabreeze summertime afternoon
convection, persistent southerly to southeasterly flow will
continue to pump moisture in the area. So any stronger storm will
still have potential to produce high rainfall rates. However, the
overall threat of heavy rainfall and flooding potential has
diminished. Just cannot completely rule out a spot of two getting
street flooding or ponding of water especially in the harder hit
areas the past few days.
Heat will become the biggest concern for this week. Highs will
start around normal for this time of the year with high
temperatures in the upper 80s to low 90s. But by mid to late this
week, it will be above normal with highs in mid 90s by Saturday.
In addition, low temperatures will hover right around the upper
70s to 80s so there will not be a lot of relief at night either.
Adding humidity into the mix will have heat index values of around
100 early this week climbing into the mid to upper 100s by late
this week. If the heating trend continues on track this week, there
is potential for needing heat advisories by the weekend.
Rip currents still remain a concern for much of this week as the
onshore flow is forecasted to remain through the forecast period.

.AVIATION...
(00Z TAF Issuance)
Issued at 624 PM CDT Sat Jun 6 2026

Today`s shower and thunderstorm activity has largely ended with
just some isolated showers lingering through sunset. The region
should be rain-free through tonight, though cannot out rule an
isolated storm moving into CLL from the NW late tonight into early
tomorrow morning. Scattered showers and thunderstorms are again
expected to develop across much of the area by the late morning
through the afternoon. Conditions are a bit more unfavorable for
TS development compared to the past couple of days, but an
isolated storm is still expected. At this time, due to confidence
levels and expected level of coverage, have gone with VCSH with
PROB30 of TS for much of the area tomorrow between 16-22z.

VFR conditions will continue through this evening, but moist low-
levels will bring MVFR conditions to the region by 3-5z with low-
end MVFR to high end IFR (700-1200ft) CIGs possible late tonight
into early tomorrow morning for most terminals except the coast
(GLS and LBX). VFR conditions are expected to return by the late
morning on Sunday. Winds will be SSE around 5-8kt overnight, and
then 8-12kt during the day on Sunday (with gustier winds near any
developing thunderstorms).

.MARINE...
Issued at 1250 PM CDT Sun Jun 7 2026

Onshore winds will continue for the the next week. Winds current
are around small craft exercise caution criteria so flags have
been issued for today. Additionally the winds will oscillate in
and out of small craft exercise caution criteria during the week.
Isolated showers and storms will be possible early this week but
chances decrease as the week goes on.
