...New AVIATION...

.SHORT TERM...
(Tonight through Monday night)
Issued at 156 PM CDT Sat Jun 8 2024

Aloft we have the ridge centered over the CWA. This will help in
suppressing any afternoon convection for the rest of the day and
into tomorrow as the upper ridge repositions itself over the
northcentral Gulf of Mexico. From Sunday, near zonal to WNW flow
setting up over the area. Closer to the surface we have the area of
high pressure centered over the southeast, with it elongated over
the CWA. Winds across our area are mostly light and variable to
southerly. As the high continues to drift away, we will see
southerly flow become more established over us. With moisture
return, expect an increase in cloud cover.

While the ridge should suppress most of the activity today, we could
see some diurnal and light activity tomorrow over the waters,
however PoPs onshore remain less than 15% at the moment. Our next
shot of rain will come on Monday as a front approaches and moves
through the area. Isolated to scattered showers and storms are
expected to ramp up over the late morning hours and linger into the
late afternoon timeframe. Severe weather and heavy rain are not
expected at this time.

.LONG TERM...
(Tuesday through next Friday)
Issued at 156 PM CDT Sat Jun 8 2024

Very little change in thinking for the longterm forecast period. A
weak frontal boundary draped along the Louisiana coastline will be
the main focus of shower and thunderstorm activity each afternoon.
Daily daytime PoPs in the ballpark of 30 to 50 percent can be
expected.

Temperatures in the low 90s and high humidity will bring about Heat
Indices around 100 each day with a slow increase into the lower 100s
by the end of the work week.

.AVIATION...
(06Z TAFS)
Issued at 1143 PM CDT Sat Jun 8 2024

Only significant change since the previous TAF package was to
include the mention of fog at LFT and ARA later tonight/near
sunrise. Guidance is still hitting on fog more so at other sites
but there is at least some agreement with fog moving into Acadiana
prior to sunrise, so went ahead and added tempo groups to account
for this. Otherwise, no changes with light winds and VFR
conditions prevailing.

.MARINE...
Issued at 156 PM CDT Sat Jun 8 2024

A light to occasionally moderate onshore flow will persist into
early next week, becoming somewhat variable as a weak front stalls
near the coast. Dry weather is expected to prevail into tonight,
with rain chances increasing over the northwest Gulf of Mexico on
Sunday...spreading to the inland lakes and bays by Monday. From
there through the work week, daily isolated to scattered showers
and storms can be expected.
