High pressure, both in the low and upper levels, will be making 
its way westward into the region today into the weekend. We can't
rule out a few isolated coastal showers this morning, and maybe a
tstm or two late in the day/evening (HRRR seems to like areas 
between IAH and Lake Livingston), but overall rain chances will 
continue on a downward trend for the majority of the area.

More sun and drier air also translates to increasing temperatures 
unfortunately. Daytime highs will trend back into the mid 90s this 
weekend. We might even need a further bump in the fcst and into the 
95-100F degree range for some locations Mon-Wed. That's when llvl
ridging should be centered just to our south...and favors a swly 
flow which tends to allow readings to climb quickly. 

Mid level ridging across the Rockies will sink ssewd during the 
second part of the week that'll reinforce the dry, hot wx for the 
remainder of the work week.  47

(00Z TAF Issuance)
Issued at 627 PM CDT Thu Jul 16 2026

Iso-sct showers and storms will continue to push across SE Texas 
through this evening and dissipate gradually as diurnal heating 
and instability decreases. IFR-MVFR cigs/vis and VRB winds at 
around 10-15 KTS with gusts up to 25 KTS are possible in storms. 
Otherwise, expect winds to gradually decrease this evening, 
relaxing to 5 KTS or less tonight into early Fri morning. Mostly 
VFR conditions are expected throughout the nighttime hours, 
however, some sites could see MVFR cigs early Fri morning for a 
few hours along with isolated areas of patchy fog. Fog, if any is 
expected to burn off around 14-15Z and cigs will gradually lift 
and scatter out shortly after sunrise. Winds will be S-SE at 5-10 
KTS on Fri.

SSE-S winds 10 to 15 knots and 2-4 foot seas should prevail across 
the coastal waters today into Saturday. With high pressure moving 
into the northwest Gulf later in the weekend, look for wind speeds 
to diminish and take on a more southwesterly component at night and 
in the mornings until the seabreeze kicks in. Corresponding wave 
heights will also trend down closer to 2 feet Sunday and beyond.
