Update
Updated for the 06z aviation discussion.

Aviation
Vfr conditions prevail at all area airports and will persist
through the morning hours. However, periods of vicinity showers
and storms are possible at most area airports through the morning
and afternoon hours Wednesday that could cause lower ceilings and
visibilities. These storms could cause temporary wind shifts
greater than 30 degrees as well. Msw

discussion...

overall synoptic overview of the northern gulf coast states
continues to reflect an unsettled summertime pattern thanks to
weak low mid level heights and ample daytime heating - leading to
daily afternoon evening rain and storm chances. Only local
enhancement to note is a weak inverted trough in the low mid
levels, generally situated from the ms delta, NE to southern al.

While most convection across inland locations should come to an
end after sunset, some overnight showers or perhaps a few storms
may persist across southern ms, generally along and north of
i-10 12 and east of i-55 due to supportive dynamics convergence in
association with the westward progressing inverted trough.

Blended guidance did hint at this enhancement, with some
overnight pop's in this location, but have kept higher pop's
across offshore zones due to overnight marine instability in
place.

By Wednesday, the aforementioned weak inverted trough tracks west
across central la, with a deep southerly moist return flow
developing across most of SE la and southern ms. This will help
drag a tongue of enhanced pw of around 2.3-2.5", combined with
increasing southerly 925-700mb layer winds ~10-20knots. Overall
impact will lead to an increase in storm coverage tomorrow, with a
few stronger thunderstorms possible producing wind gusts
25-35mph. This increase in low-level flow may help move storms a
bit more, with an average storm motion 180 8kts, but being this
weak means storms will largely propagate from outflow boundary
interactions and still produce localized flooding.

The southerly return flow will persist and deepen Thursday and
into Friday, with continued anomalously high pw each day leading
to widespread shower and storm chances. Weak storm motions
continuing to average around 180 7-8kts will allow for a
persistent day-to-day threat of localized flash flooding, as well
as gusty downdraft winds.

This upcoming weekend into early next week will feature much of
the same story. Interesting to note the nam GFS points at some
type of small (perhaps mesoscale?) low to mid-level spin up in the
nw gomex under weak heights aloft. H5 temps illustrate this to
have a warm core with it so this may need to be monitored. Only
local impacts should be continued day-to-day widespread
shower storm chances. Good news is with so much rain, temperatures
appear to remain near to slightly below normal, with no signs of
excessive heat in the long range at this time. Klg
marine...

overall weather pattern will continue to remain unsettled across
marine zones, thanks to a weak inverted trough across coastal se
la and southern ms areas. Expect spotty shower storm chances
through the next several days, with better coverage in the
overnight hours. Main threats in any one storm will be gusty
downdraft winds in excess of 25-35 knots and lightning. This
pattern should continue through the weekend and early next week.

Klg
aviation...

convective development will be the primary concern through 00z.

Have included vcts wording at all of the terminals to reflect this
risk, and have prevailing MVFR visibilities and showers at khum
where ongoing convection is most pronounced today. Given the high
soil moisture values in place at kmcb, kbtr, khdc, and kasd from
previous rains, another round of low ceilings and fog will be
possible tonight. Have prevailing lifr ceilings developing after
10z and lingering through 14z at these terminals, and have also
included some ifr visibility restrictions at kmcb around 12z
tomorrow. The low stratus deck should gradually lift into an MVFR
layer of 1500 to 2000 feet at these terminals after 15z tomorrow.

The remaining terminals should see MVFR ceilings of around 3000
feet after 15z tomorrow as cumulus development increases with
daytime heating. 32
