.SHORT TERM...
(Tonight through Monday night)
Issued at 345 PM CDT Sat Jun 1 2024

In the near term, expanded Severe Thunderstorm Watch #365 a small
ways to the east earlier after collaborating with SPC as ongoing
convection within the initially issued watch was moving eastward
out of the watch into an area that was also conducive to severe
potential. No change to the watch's expiration time.

Mid-afternoon sfc analysis shows a trof/convergence boundary
sitting along roughly the I-10 corridor, otherwise high pressure
centered along the Carolina coast is remaining in control with
srly low-level flow in place. Water vapor imagery shows weak
troffing in place over the center of the country with a
significant shortwave dropping through it approaching the region
at this time. The combo of these features along with a very moist
airmass (12z KLCH sounding showed a PWAT near 1.8 inches which
forecast soundings indicate is likely higher this afternoon) has
led to another round of scattered/numerous showers/thunderstorms
which initiated near the coast over sern TX and have been
gradually spreading ewd (as lift spreads ahead of the wave) and
inland (via outflow development/collisions).

This convection is expected to linger into the evening hours
before sunset/loss of heating leads to a gradual dissipation.
Until then, the severe threat lingers (thus the going WW) while
the flash flooding threat, already present as noted in reports
received from sern TX, likely grows due to continued development
and slow storm movement. In response, WPC has upgraded the
forecast area to a slight risk for the remainder of today into
tonight.

Sunday looks fairly similar to today as another shortwave is
progged to push ewd across the region within a developing zonal
flow aloft behind the departing trof axis. Forecast soundings
indicate good moisture lingering (mean RHs around 80 percent and
PWATs nearing 2.0 inches which exceeds the 90th percentile per SPC
climo). With daytime heating/mesoscale impacts, expecting yet
another round of convection with elevated rain chances. SPC has
highlighted the swrn 2/3 of the forecast area in a marginal risk
for severe with damaging wind gusts being the main concern
(although recent days have shown that large hail will likely be
part of the equation again). Meanwhile, WPC has highlighted the
entire area again in a marginal risk for excessive rainfall...
while forecasted QPF values don't look menacing, the antecedent
wet conditions will allow for lesser rainfalls to create flooding
issues.

Monday should finally bring some dry weather as the nearly zonal
flow begins getting replaced by weak ridging aloft. Forecast
soundings indicate less capping and better moisture over the nern
zones...and with daytime heating being the primary driver, we
could see a few showers/storms during the afternoon across mainly
the Atchafalaya Basin/e-cntl LA.

.LONG TERM...
(Tuesday through next Friday)
Issued at 345 PM CDT Sat Jun 1 2024

The long term begins Tuesday with ridging developing aloft in
response to a mid/upper-level low digging swd through the Desert
SW into nwrn Mexico...the resulting capping should keep convection
at bay across our region despite the continued good low-level
moisture. Wednesday currently looks like a repeat performance,.

Rain chances, albeit small, return to the forecast for Thursday
and Friday as the ridge begins breaking down in response to a
digging trof over the ern CONUS...the resultant weak capping
allowing for widely scattered convection to develop mainly over
our nern zones.

Temperatures are progged to start rather seasonal with daytime highs
around 90F, although warmer than normal mins are forecast with
readings all through the 70s. A slight warming trend is in the works
with highs in the lower/mid 90s by period's end...overnight lows
remain rather static.

.AVIATION...
(18Z TAFS)
Issued at 1255 PM CDT Sat Jun 1 2024

No real changes to going TAF thinking with scattered convection
expected through this afternoon, especially for the srn terminals,
before dying off with sunset. MVFR or lower ceilings are likely
again tonight with so much low-level moisture in place pooling
below a lowering inversion. Some light fog also looks probably,
especially where rain falls today. Conditions will improve after
sunrise Sunday.

.MARINE...
Issued at 345 PM CDT Sat Jun 1 2024

No headlines are anticipated on the CWF until Monday when a
tightening gradient on lowering pressures over the srn Plains lead
srly winds to increase to caution criteria.
