Area Forecast Discussion
National Weather Service Houston/Galveston TX
1242 PM CDT Wed Jul 14 2021

.AVIATION [18Z TAF Issuance]...

Scattered to numerous showers and tstorms this afternoon will
increase in coverage and intensity, especially for sites south of
CLL and UTS. Ceilings will be VFR, but expect tempo MVFR with
these passing showers and tstorms. Activity should subside
shortly after sunset with the lack of daytime heating.
Prevailing MVFR ceilings possible for sites CXO and north
overnight. Shower activity picks up again for our coastal sites
(LBX and GLS) early tomorrow morning with a repeat in afternoon
showers and tstorms tomorrow.

.PREV DISCUSSION /Issued 331 AM CDT Wed Jul 14 2021/...

SHORT TERM [Through Thursday Night]...

Precipitation coverage yesterday was much more widespread and
intense than forecast and that makes today's forecast somewhat dicey
as conditions look similar to yesterday. A weak inverted upper level
trough is located over South Texas and this feature will extend into
SE TX. PW values remain robust with PW values ranging from 2.00
inches over the far SW zones to 1.70 inches over the far NE zones.
Forecast soundings show weak capping near 850 mb but the cap can be
broken with heating. Convective temperatures are only in the upper
80's today so convection should initiate by late morning and expand
in coverage and intensity this afternoon. Fcst soundings show CAPE
values between 2500-3000 J/Kg and LI values between -4 and -8 so a
few of the storms could briefly pulse to severe levels and produce
locally heavy rain much like yesterday. 850 mb temps look about 0.5
degrees cooler than yesterday so MaxT values should be similar or a
degree or so cooler than yesterday. MaxT values should again warm
into the lower 90's but will will dependent on when storms develop.
Precipitation should wane with the loss of heating and any residual
showers should end by 02z.

500 heights increase slightly on Thursday but the overall pattern
doesn't really change that much. Forecast soundings again show a
weak but breakable cap near 850 mb. Convective temperatures remain
in the upper 80's with PW values between 1.80 and 2.00 inches. MaxT
values look a bout the same as today with no appreciable change in
850 mb temps. Precip will end by 02z with the loss of heating with
skies clearing overnight. 43

LONG TERM [Friday Through Wednesday]...

The weather Friday through Sunday will be fairly consistent as an
upper level high pressure remains draped across the southern half
of the US. Low level moisture combined with daytime heating will
lead to the chance of scattered afternoon showers through the
weekend and into next week. An upper level low will be dropping
southward from the Upper Midwest Monday into Tuesday with a
boundary setting up west to east from North Texas to the
Carolinas. This boundary will end up sliding into our northern
counties late Monday night and then potentially continue southward
during the day on Tuesday before eventually stalling/washing out.
There is some disagreement in the guidance on how far south the
boundary will push. The GFS keeps the boundary located north of
Conroe while the EC is more aggressive, bringing the boundary all
the way to the coast by Wednesday afternoon. Leaning more toward
the GFS solution, but we are still about a week out, so things may
change. And in either solution, expect scattered precipitation
through Wednesday.

No big changes in the diurnal temperatures through the week with
afternoon highs in the low to mid 90s and overnight lows in the mid
70s. Heat indices over the weekend will potentially be peaking in
the 105 - 110 degree range, so will need to monitor for the need for
heat advisories in the coming days.

Fowler

MARINE...

Light to moderate southeasterly flow will persist through the start
of next week becoming more southerly by midweek next week. Wave
heights will continue to be between 2 to 3 feet through at least
midweek next week. Rip current threat remains low, but remember rip
currents can occur even during low risk - especially near jetties.
Isolated to scattered showers and thunderstorms will be possible
each day, mainly during the morning and afternoon hours.
