...New AVIATION...

.UPDATE...
Issued at 918 AM CDT Wed Aug 24 2022

The wet pattern continues this morning with widespread light
showers with embedded heavier rainfall spread across much of
central, south central and southwest Louisiana. The general trend
from the latest high res guidance is for this activity to persist
over the next few hours with additional development across
southeast Texas through the early afternoon. This should be
followed by a gradual lowering of coverage through the evening. The
precip and cloud cover will once again hold afternoon highs in
the low to mid 80s.

Will evaluate the need to extend the flood watch further with the
afternoon package, but trends so far this morning make that a
likely proposition.

.SHORT TERM...
(Today and tonight)
Issued at 215 AM CDT Wed Aug 24 2022

Scattered thunderstorms are redeveloping already this morning.
Radar estimates over the past 4 days from at some locations are 5
to 10", however most locations are 1 to 5" with lesser amounts
near the coast. The ground is generally saturated across a large
portion of the area, especially the northern zones.

A cold front remains stalled to the north with a very moist air
mass in place south of the boundary. PWATs are above the 90th
percentile. With the weak convergence and upper divergence in
place and the high moisture content, high rain chances are
anticipated. While guidance has seemed to somewhat overestimate
coverage, widespread convection is expected. Hi-res guidance is
indicating fairly high rainfall totals over locations that
have received significant amounts over the past few days, plus
they are slightly more focused from Jefferson Co through Rapides.
Opted to expand the FFA farther south for today.

A lull in convection may occur this evening, however another round
of wet weather is expected Thursday as the same pattern remains in
place.

For Friday the weak surface convergence begins to lift northwest,
but the overall pattern will remain in place. More rain.

&&

.LONG TERM...
(Thursday through Tuesday)
Issued at 215 AM CDT Wed Aug 24 2022

Forecast for this weekend into early next week look to remain on the
wet side with above seasonal pops each day. The reason will be a
relative weakness overhead in the sub-tropical ridge, while
southerly flow continues to bring in abundant Gulf moisture. Even
though there will be no low level surface boundary around to focus
storm development, daytime heating and an active sea breeze should
be enough for a good deal of showers and storms from late morning
into the afternoon.

With the expected extra cloud cover and convection, high
temperatures each day are expected to be a little below climo norms.

.AVIATION...
(18Z TAFS)
Issued at 1248 PM CDT Wed Aug 24 2022

Widespread showers and scattered thunderstorms will continue
through the afternoon and early evening hours before becoming more
isolated by late evening. Gusty winds and visibility restrictions
can be expected in the vicinity of these storms.

The significant rainfall that has fallen thus far today along with
light winds overnight could lead to some areas of fog or low
ceiling development especially at AEX, but confidence in this
isn't high enough to include anywhere except AEX at this time.

Redevelopment of showers is expected to begin again very early
Thursday morning with thunderstorms again developing by mid to
late morning.
