...New AVIATION...
.KEY MESSAGES...
- A Flash Flood Watch which includes most of southwest Louisiana
is in effect through Saturday.
- Heavy rainfall from a tropical disturbance will remain possible
through Saturday.
- Heat returns to the region in the middle of next week with highs
in the mid to upper 90s.

.SHORT TERM...
(Today through Monday night)
Issued at 1220 AM CDT Sat Jul 19 2025
Tonight and Saturday will see another round of showers and
thunderstorms before a building ridge settles overhead and starts
to limit convection.
With the remnants of the tropical low now well to our north,
forcing across the region will be much weaker. With a more stable
pattern, the extent of the convection will be limited. Still, PWAT
values remain above 2 inches, and isolated heavy rain isnt out
of the realm of possibility. But we will be dropping the flash
flood watch earlier than originally planned with the watch
expiring at 12Z to cover any nocturnal flare ups. After sunrise
the threat of widespread flash flooding will have passed.
Aloft, a building ridge will be the main weather feature through
the weekend and into the start of next week. This ridge will limit
convection and cause our temperatures to rise. This pattern will
extend through the rest of the week.&&
.LONG TERM...
(Tuesday through Saturday)
Issued at 1220 AM CDT Sat Jul 19 2025
Upper-level ridging will continue to impact the region with highs
reaching the mid-90s along the coast and the upper 90s in central
Louisiana and the interior portions of southeast Texas. There is
a chance we could see temperatures break into the triple digits,
especially in the inland areas. Heat index values will get close
to the heat advisory criteria of 105. Even if we dont meet the
requirements, heat safety precautions should be taken, including
taking breaks from the heat and drinking plenty of water.
Near the end of the week, rain chances will rise as another surge
of tropical moisture moves into the area.

(12Z TAFS)
Issued at 616 AM CDT Sat Jul 19 2025
Light mainly southwest to south winds and VFR scattered to broken
ceilings can be expected across all sites through the forecast
period. A few isolated showers are ongoing across south LA, and
this activity is expected to continue through the morning hours
while expanding a bit in coverage. Activity should remain fairly
isolated today, therefore just kept mention of VCSH/VCTS in the
forecast to account for an occasional shower/tstorm passing near
the terminals.

.MARINE...
Issued at 1220 AM CDT Sat Jul 19 2025
Current observations show seas around 2 to 4 feet with winds
around 10 knots from the southwest. The remnants of the tropical
disturbance have moved onshore, and impacts to our coastal waters
will be limited to thunderstorms. Storms can produce locally
higher winds and seas. Thunderstorm coverage will decrease on
Saturday night.
&&
.FIRE WEATHER...
Issued at 1220 AM CDT Sat Jul 19 2025
Widespread heavy rain has soaked most of the region. Patchy
showers will continue on Saturday before a dry spell starts on
Sunday. Minimum RH values will remain high, around 40 to 60%. Due
to high pressure overhead, winds will be light for the next
several days, less than 10 mph.
