.DISCUSSION...
Issued at 1145 PM CDT Thu Jul 23 2026

Bertha dissipated earlier this evening over the Houston metro
area. All that`s left is a remnant trough with a few light showers
as it continues to slide off to the west. Drier air begins to more
in during the day Friday, but there may be just enough residual
moisture to generate a few isolated showers, mainly west of I-45
closer to Bertha`s remnants. Otherwise, we become mostly sunny
again with highs in the low to mid 90s. We should mix out our dew
points just enough to prevent a Heat Advisory for Friday.

Ridging builds over the central US again this weekend and lasts
well into next week. Rain chances will be near nil, but the
temperatures will be on the rise. We should see highs climb into
the mid to upper 90s this weekend, followed by near or exceeding
100 next week for inland areas. We`ll still have lower daytime dew
points on Saturday, so we should remain below advisory levels, but
starting Sunday, each day has the potential of needing a Heat
Advisory as humidity levels slowly climb.

.AVIATION...
(12Z TAF Issuance)
Issued at 526 AM CDT Fri Jul 24 2026

GOES PW imagery shows some drier air beginning to move into the
region from the ESE, though with values still in the 1.7-2.0"
territory, one cannot rule out some isolated showers today. That
said, they should be short-lived at any individual site with
little impact...so these chances won`t be mentioned in the TAFS.
Otherwise, some sporadic MVFR cigs should lift into VFR territory
areawide by 15-16z. Southerly winds 10-15kt should diminish after
sunset. SREF indicates some patchy fog potential west and north of
the metro area late tonight/early Sat morning.  47

.MARINE...

Winds and seas will continue to subside in the wake of Bertha.
Small craft should exercise caution through Friday morning with
winds of 15-20 kt and seas around 4-5 feet. Light to moderate
south to southwesterly winds will prevail thereafter with 2-3 foot
seas.
