  warranting advisories by Sunday or Monday.

.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...
(00Z TAF Issuance)
Issued at 727 PM CDT Thu Jul 23 2026

Lingering showers and storms associated with now Tropical
Depression Bertha continue to push westward and away from the
Houston metro terminals. Some lingering rain showers will remain
possible over and around area terminals themselves through 02-03Z.
Afterwards, the main impact will be the timing of MVFR ceilings
lifting back to VFR which as of right now looks to be generally
between 05Z-12Z from south to north overnight. Southeasterly to
southerly winds will prevail late this evening into Friday with
sustained winds around 10 kt and occasional gusts around 15-20 kt
through the afternoon. Some isolated showers will be possible
Friday late morning/afternoon, but coverage is too low for any TAF
mentions.

Winds and seas will continue to subside in the wake of Bertha.

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.
