...New AVIATION...
.KEY MESSAGES...
- Very typical summer pattern will persist through the forecast
period with daily afternoon thunderstorms, afternoon highs in
the low to mid 90s and max heat indices from 98 to 106 degrees.
- Somewhat higher precipitation chances Sunday in response to
higher tropical moisture surging into the region.
&&
.SHORT TERM...
(Today through Sunday night)
Issued at 331 AM CDT Fri Jun 27 2025
The typical summertime pattern of very weak gradients both at the
surface and aloft and daily, diurnally driven, afternoon
convection will be the story through much of the next week. The
weak gradient will keep winds at the surface and aloft generally
under 10 knots as was observed on both of yesterday`s RAOBs. These
conditions supported the development of several tropical funnels
and waterspouts along colliding outflow boundaries and rapidly
developing marine storms. Conditions are expected to remain
favorable for tropical funnels and waterspouts through the weekend
and much of next week.
As a reminder, while tropical funnels can sometimes appear
visually impressive, they rarely reach the ground and, when they
do, often produce winds that are much weaker than those of a
traditional tornado as they are not supported by a mesocyclone.
They are also very difficult to observe on radar since their
circulation only extends to the cloud base which may be only a few
hundred feet off the surface. If a reliable report of a tropical
funnel on the ground is received, then a tornado warning will be
issued, but this is very rare.
The only real change in the overall pattern will be Sunday where a
higher surge of mid and upper level tropical moisture will work
inland off the gulf increasing the coverage of afternoon
convection. Even so, these will still be primarily diurnally
driven with the majority of storms dissipating by around sunset
Sunday evening.
Otherwise, highs in the low to mid 90s with heat indices ranging
from 98 to 106 will occur each day with lows falling into the mid
70s each evening.

.LONG TERM... (Monday
through Friday) Issued at 331 AM CDT Fri Jun 27 2025
The typical summertime pattern continues with very little
variation in day to day temperatures or precipitation chances
which will range from 30-40% across Southeast Texas and western
Louisiana and 50-60% in and around the Atchafalaya basin.

.AVIATION...
(12Z TAFS)
Issued at 633 AM CDT Fri Jun 27 2025
VFR conditions will prevail this morning along with light
southerly winds. Scattered thunderstorms will develop across the
region beginning around 18Z through sunset with storms most
likely to affect LFT and ARA. Rapid shifts in wind direction may
occur in the vicinity of developing thunderstorms as outflow
boundaries move through terminals. Storms will dissipate around
sunset with VFR conditions expected to prevail again overnight
into Saturday morning.

.MARINE...
Issued at 331 AM CDT Fri Jun 27 2025
A surface high off the southeast U.S. coast will continue to
ridge across the northern Gulf and into the coastal through the
weekend into early next week resulting in light onshore flow and
low seas. Daily showers and thunderstorms are expected with little
day to day change.
&&
.FIRE WEATHER...
Issued at 331 AM CDT Fri Jun 27 2025
Light southerly winds will maintain low level moisture with minimum
afternoon RH in the low to mid 50s across interior southeast
Texas as well as central Louisiana and in the low to mid 60s
along the I-10 corridor to the coast. Typical summertime
pattern will continue through the weekend with daily afternoon showers
and thunderstorms along with hot, humid days and muggy nights.
