.DISCUSSION...
Issued at 1105 PM CDT Thu Jul 10 2025

Daily chances for showers and thunderstorms will prevail through
early next week as Southeast TX continue to be wedged between a
high pressure systems situated over SW CONUS and another high
pressure system situated over the eastern Gulf and SE CONUS,
allowing for weaknesses to pass overhead. For today (Friday), we
will likely see similar conditions to yesterday, except with
slightly more coverage in showers and thunderstorms (~20-40% PoPs)
as moisture recovers a little more. By Saturday, rain chances
will increase as an upper level trough moves across the Southern
Plains, a weak vort max lingers aloft, and PWs rise to 1.9-2.1
inches. We are expecting isolated to scattered showers to start
over the Gulf and coastal locations during the early morning
hours, followed by scattered to widespread showers and
thunderstorms developing further inland during the mid morning to
late afternoon hours. Storms are expected to dissipate during the
late evening to early night hours. These storms may end up being
efficient rain makers, with rainfall rates of 2-3 inches per hour
possible and could lead to ponding of water along roads and poor
drainage areas. Thus, make sure to take a peek at the radar and
traffic conditions before departing to your destination. Remember
to never cross flooded roads. In addition, stronger storms can
produce strong gusty winds and frequent lightning. If you plan to
spend time or work outdoors, if thunder roars, head indoors.
Similar conditions, but with maybe a little less storm coverage,
can be expected on Sunday.

A decreasing trend in rain coverage/chances is possible Monday
into the mid-week period. The rains and cloud coverage have
allowed us to enjoy the high temperatures peaking in the lower
90s for much of region these past few days. However, the decrease
in rain activity could mean hotter conditions as we progress into
the mid-week period, with highs possibly rising into the mid and
upper 90s for portions of Southeast TX. Heat indices could rise
to near Advisory criteria in some spots. Let`s hope the models
change their minds and keep us on the current cooler summer trend.

.AVIATION...
(00Z TAF Issuance)
Issued at 604 PM CDT Thu Jul 10 2025

Isolated showers and storms have developed along a diffuse sea
breeze that is passing through IAH at this time. Any storms
currently out there will dissipate within the next hour or two.
Like last night, VFR conditions will generally prevail, but some
patchy fog or low CIGs may develop shortly before sunrise then
quickly dissipate after sunrise. Like today, isolated showers and
thunderstorms may develop along the sea breeze in the afternoon.
Southerly winds persist around 4-6kt overnight, then increasing to
around 8-12kt during the day.

.MARINE...
Issued at 1105 PM CDT Thu Jul 10 2025

Light to occasionally moderate onshore winds and seas of 2 to 4
feet will persist for the next several days. Periods of showers
and thunderstorms are anticipated through early next week, then a
gradual decrease in activity is possible. For the next few days,
the weather pattern will be a "rinse and repeat" with showers and
thunderstorms developing along the Gulf waters and coastal
locations during the early morning to early afternoon hours,
followed by activity moving further inland during the mid
afternoon to evening hours. However, a strong storm or two cannot
be discarded during that timeframe, in particular over the bays.
Stronger storms could produce strong gusty winds, outflow
boundaries, and higher seas at times.

Along the Gulf facing beaches, persistent onshore flow will
result in a moderate risk of rip currents. High risk of rip
currents could occur at times. Please follow the beach flag
conditions, and always swim near a lifeguard.
