Discussion See aviation section for 00z tafs.

Aviation Isolated convection will continue to move inland
across south texas over the next couple of hours. But activity
should continue to show diminishing trends with loss of heating.

MVFR vsbys ceilings will be possible with passing showers.VFR
conditions are expected through tonight except for possible
MVFR ceilings over the coastal bend into the southern brush
country before daybreak. Expect another round of showers to
move inland across the coastal bend early in the morning as
the mid level low over the northwest gulf of mexico approaches.

MVFR vsbys ceilings will occur with the showers through 15z.

Convection will gradually move inland through the afternoon
and affect the victoria crossroads and eastern brush country.

Chance of storms will not be high enough to insert in lrd cot
tafs Monday afternoon. MVFR to ifr vsbys will occur with the
showers and thunderstorms respectively in the afternoon over the
coastal plains.

short term (tonight through Monday night)...

short term period continues to be dominated by an upper level
disturbance over the western gulf of mexico. This, combined with
increasing tropical moisture will continue a persistent pattern of
at least scattered showers and thunderstorms across much of the
area. Highest rain chances will remain east, but moisture does
spread far enough west to bring in slight chances west by Monday.

Inverted trough in the low levels tonight through Monday should
move to the coast or slightly inland by Monday night. Through
Tuesday night, area averaged QPF should remain under half an inch
for most of the area as pwat values becoming only marginally above
normal. Highest moisture hold off until Tuesday. Winds will be
mainly east to northeast through Monday as a result, but will
begin to shift southeast along the coast as the trough moves
inland. High temperatures should be held down a bit... To more
normal levels with increasing cloud coverage. Low temps expected
in the 70s due to the increased moisture.

Long term (Tuesday through Sunday)...

the main feature of the long term period will be a broad mid level
low over the northern gulf of mexico which can be seen on water
vapor imagery this afternoon. The low is expected to slowly move
west through mid week. This will result in increased moisture, with
pwats reaching 2.3-2.4 inches by Wednesday afternoon which is about
2 standard deviations from normal for mid september. With plenty of
moisture, expected showers and thunderstorms to be efficient with
heavy rainfall possible. Wpc has a marginal risk of excessive
rainfall for much of south texas on Tuesday with a slight risk
along the immediate coast. While widespread rain does look likely
for Tuesday through Thursday time period, have bumped pops down some
from blended solutions to around 50-60%. There are still differences
between models runs with how long the mid level low will linger over
south texas before eventually lifting north. For now have pops
decreasing Thursday night into Friday, but that may need to be
adjusted if the low stalls. Ridging will build in behind the low,
keeping us drier for the weekend. The GFS has the ridge staying in
place over texas through early next week, while the ECMWF shows
another easterly wave approaching the texas coast. With mostly
cloudy skies, high temperatures will be at or slightly below normal
with highs in the 90s through the week.

Marine...

shower and thunderstorms will be likely daily through Thursday as
an upper level disturbance remains over the region. Light to
moderate northeasterly flow will persist Monday, then shift around
to the southeast by Monday night as a coastal trough shifts
inland. This light to moderate onshore flow will then persist
through the end of the period.
