Short term (today through Saturday)
The moist summer pattern will continue, although today should be
a slight reprieve from the higher rain coverage of the last couple
days. A bermuda ridge pattern will dominate the central gulf
coast region with fairly typical, scattered diurnal showers and
thunderstorms expected with daytime heating. Of interest in the
tropics, a trough of low pressure over the bahamas may try to get
better organized by this weekend as the system approaches the
florida peninsula, however this system will not have impacts to
the central gulf coast region. Of more interest locally, satellite
imagery shows a well defined mid upper level low over the
southwest gulf of mexico that is moving northwest. The models are
in decent agreement taking this low trough northwest then north
today through Friday across the western gulf reaching off the
texas coast by Friday afternoon. This should bring another surge
of deeper tropical moisture into the forecast area on Friday, so
have maintained the high rain chances from the previous forecast.

The weather prediction center has kept most of the area in a
marginal risk of excessive rainfall on Friday and the pattern
definitely supports locally very heavy rainfall amounts that may
result in ponding of water and some flooding. A few stronger
thunderstorms producing frequent lightning and gusty winds may
also occur mainly during afternoon hours today and tomorrow.

On Saturday, a shortwave trough moving east across the northern and
central plains region is expected to have enough westerly flow down
to the red river valley area to cause the mid level low trough to
drift north to northeast near the upper texas and southwest
louisiana coast on Saturday and Saturday night. The ECMWF builds
the low pressure area or a trough down to 850 mb by Saturday
evening. This will likely continue to keep the forecast area in
deeper tropical moisture that will support high rain chances along
with locally heavy rainfall.

Long term (Sunday through Wednesday)
A low or trough of low pressure from the mid levels down to 850 mb
should drift northeast to east near or over southeast louisiana on
Sunday. Once again, this will maintain deep tropical moisture and a
favorable environment for fairly widespread rainfall and a threat of
locally very heavy downpours from heavier showers and thunderstorms.

This system should finally start to exit the region on Monday,
however there will still be deep tropical moisture over the region
to support scattered to numerous showers and thunderstorms. In fact,
it should remain a fairly wet pattern with scattered showers and
thunderstorms Tuesday into Wednesday as a frontal boundary will
start to approach the region from the north as a fairly potent
series of shortwave troughs carve out a broader mid upper level
trough across the upper to mid mississippi valley and great lakes
region. 22 td

Aviation
All terminals currentlyVFR, although kmcb has recently had some low
stratus, producing ceilings at fl004. Certainly some potential for
MVFR to ifr ceilings over the next few hours with some fairly
shallow and isolated convection moving off the gulf of mexico.

Carrying vcsh in the near term to handle this. If there is going to
be fog around sunrise, it's most likely to be at kbtr and kmcb, but
can't rule it out at khum, khdc and kasd. Improvement likely by 14-
15z. A few hours of MVFR ceilings will be possible as the cumulus
field develops at mid-morning, with scattered convection likely to
develop by mid-day. Any mention of thunder will be limited to vcts
for now until area of main focus becomes more apparent. Brief ifr
conditions with any thunder that directly impacts a terminal. Threat
diminishes again by sunset. Fog threat for Thursday night will be
dependent on when and where precipitation occurs during the daytime
hours. 35

Marine
Overall weather pattern will continue to remain unsettled across
marine zones, thanks to a weak inverted trough across southern and
central louisiana. 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 35
