.SHORT TERM...
(Tonight through Monday night)
Issued at 400 PM CDT Sat Jun 7 2025

Another day of the same: very hot and humid conditions with
isolated showers moving over the region. High pressure remains
mostly in control off to the east, so don`t expect a break in
today`s heat. Speaking of, area dewpoints started out in the upper
70s to low 80s. Even with mixing, it took quite a lot of time for
surface layers to lose this moisture. Little cloud cover and high
humidity has resulted in max Heat Indices in the 100 to 106F
range, just shy of advisory criteria.

For the most part, expect much of the same. Very steamy start to
the day, conditions feeling very hot very fast. But as the pressure
gradient tightens again between high to the east and low over the
TX/OK border, mixing should set in and keep those HIs in check.
Cloud cover blown off storms to the northwest and slightly higher
afternoon rain chances should assist as well. Thus, a Heat
Advisory has not been issued at this time for Sunday. If this line
of thinking changes, a Heat Advisory may be required for areas of
Deep East Texas and north/central Louisiana.

A storm system is set to move down through the region on a robust
shortwave trof dropping into the southeast on Monday. Timing of
storm arrival is still somewhat nebulas, but all day rainfall due
to falling heights and deep moisture is likely. Some embedded
storms may carry all storm hazards.

.LONG TERM...
(Tuesday through next Friday)
Issued at 400 PM CDT Sat Jun 7 2025

Elevated rain chances will remain in the forecast Tuesday through
Friday as a series of weak disturbances move overhead. Periods of
on-again off-again heavy rainfall can be expected with periods of
stronger storms as well.

Rain-cooled air and cloud cover will help bring daily temps into
the upper 80s to around 90 each day. While it`ll be rainy, at
least it won`t also be scorching!

.AVIATION...
(00Z TAFS)
Issued at 555 PM CDT Sat Jun 7 2025

Fair conditions are expected through the period. Breezy south
winds will diminish to less than 10 knots after sunset, then
mainly light and variable after 08/06z.

for the most part clouds will remain scattered enough to remain at
VFR levels during the night. However, persistence suggest some
patchy fog and low clouds at MVFR levels for KAEX between
08/10z-14z.

Mainly VFR conditions again on Sunday with clouds remaining
scattered enough to preclude significant ceilings. Shower activity
during the period should also remain at a minimum and too low of
a probability to place in the terminal forecast.

.MARINE...
Issued at 322 PM CDT Sat Jun 7 2025

Light to occasionally modest onshore flow and low seas will
persist through the middle of next week. A few showers and
thunderstorms will pop up sporadically overnight and Sunday during
daytime hours. Increasing rain chances will begin late Sunday
with high rain chances expected each day, Monday through Friday as
a couple of upper level disturbances move across the region.
