Isolated to scattered showers are possible this evening, and again tomorrow. The coverage of the shower activity may increase tomorrow and Saturday compared to the past few days as a surge of tropical moisture enters the western gulf. Slightly higher seas and increased winds are expected on Saturday as this disturbance moves through. High pressure builds over texas again next week continuing the stretch of mostly normal summer like conditions for the region.

area forecast discussion
national weather service houston galveston tx
738 pm cdt Thu aug 22 2019

Aviation [00z TAF issuance]
A couple of showers are lingering over the area at this time, but
will be expecting the activity to continue to weaken dissipate as
we move into the evening. No issues overnight but with the deeper
low-level moisture continuing to move in from the gulf, we should
see the timeline of offshore activity tracking inland, speed up a
bit. Have kept with previous TAF trends with starting the mention
of vcsh vcts a couple of hours faster than previous days (15-17z).

The highest rain chances are expected to remain over the southern
half of the CWA (roughly from i-10 to the coast) during the early
part of the day... With scattered activity developing elsewhere by
the afternoon. Due to the tropical nature of the airmass, will be
expecting things to quiet down once again by Fri evening. 41

Prev discussion issued 322 pm cdt Thu aug 22 2019
short term [through Friday]...

deep low level moisture will continue to pool into the gulf waters,
gradually moving northward into the coastal regions of southeast
texas today and tonight. GOES tpw is indicating 2.1 inches across
the southern and central portions, with higher values over the
gulf waters. The increased low level moisture will continue to
induce a few more showers and thunderstorms this afternoon,
particularly over the southern half of the forecast area,
dissipating in the evening with the loss of heating. Over the
local waters however, passing showers will continue tonight, with
a few of them moving into the coastal regions from time to time.

Light southerly wind flow with low temperatures in the mid to
upper 70s expected tonight.

Friday, shower and thunderstorm activity is forecast to continue.

The low level moisture will prevail over the waters, gradually
filtering into the southern regions in the morning and spread
further inland in the afternoon. The NAM model and sounding data
for iah and gls shows the increase in low level moisture on Friday
with values starting around 2.0 inches early in the morning,
increasing up to near 2.6 inches in the afternoon. Over the
northern portions pwat values stay around 2.0 inches or less. With
the lack of strong subsidence aloft, the combination of available
moisture, diurnal effects and outflow boundaries will continue to
create a favorable environment for shower and thunderstorm
development across the local area. Although there are some
differences between the GFS and nam, both agree to keep most of
the deep low level moisture mainly over the gulf waters and the
southern regions of the cwa. Thus, kept the higher rain chances
over these areas. Look for showers and thunderstorms moving over
the waters and southern regions in the morning, expanding
northward in the late morning and afternoon. Most of the activity
is expected to dissipate in the evening, with showers lingering
over the waters and coastal regions Friday night. Due to the
increase in cloud coverage and rainfall activity, high
temperatures will be slightly cooler. 24
long term [Saturday through Wednesday]...

over the weekend, expect a wet weather pattern with showers and
thunderstorms continuing to develop from time to time as pulses
of deep low level moisture move across southeast texas. The
strongest heaviest activity should remain mainly over the gulf
waters and southern half of southeast texas. On Saturday, the nam
shows an area of pwat values of around 2.5 to 2.7 inches moving
over the southeast quadrant early morning through early afternoon.

Although slightly drier, the GFS also shows good moisture content
with values of up of to 2.2 inches during this period. On Sunday,
a similar weather pattern can be expected as another pulse of low
level moisture moves across the region.

Next week, low level moisture will decrease and the mid level
ridge looks to build back into western and central texas. A
summertime pattern can be expected with passing showers over the
local waters and coastal counties during the night and early
morning hours, followed by isolated to scattered showers and
thunderstorms developing inland during the late morning and
afternoon hours. High temperatures expected to be in the low to
mid 90s south of i-10 and in the mid to upper 90s north of
i-10... Possibly reaching 100 degrees f in the northwestern
quadrant. Low temperatures will range in the mid 70s to low 80s
each night. 24
