Updated at 154 PM CDT Sun Jun 14 2026

- NHC continues to indicate a low chance (30%) of tropical
  development over the next 7 days for a trough of low pressure
  currently located over northeastern Mexico.

- Rainy conditions will continue through at least the middle of
  next week as deep tropical moisture coincides with an
  approaching weak frontal boundary.

- WPC highlights a Moderate Risk (level 3 of 4) for excessive rainfall
  and flash flooding for Monday. A Slight Risk (level 2 of 4) is
  in place for the rest of today, Tuesday, and Wednesday.

- High Rip Current Risk and minor coastal flooding continue
  through at least tonight.

.DISCUSSION...
Issued at 154 PM CDT Sun Jun 14 2026

Deep tropical moisture will remain in place across our area through
the middle of the week, supporting quite a rainy pattern over the
next several days. Our 18Z CRP sounding has already indicated PWATs
of ~2.50 inches, and forecast guidance shows this moisture plume
persisting through at least Wednesday, with PWATs generally ranging
from 2.25-2.50 inches and locally approaching 2.60-2.75 inches. This
very moist airmass, combined with weak steering flow and efficient
warm-rain processes, will create a favorable environment for periods
of heavy rainfall and localized flooding concerns.

Multiple forcing mechanisms are expected to interact over the region
during this period. A weak frontal boundary sagging southward into
Texas will approach and likely stall near portions of the Coastal
Plains, while daily sea breeze circulations and a trough of low
pressure located over northeastern Mexico will provide additional
lift for widespread showers and thunderstorms to develop each
day. The greatest rainfall potential is expected from Monday
through Tuesday night. Current rainfall forecasts support
widespread totals of 3-5 inches across the region, though isolated
higher amounts up to 6-8 inches will likely occur where training
convection develops. Based on the environment and HREF
probabilities, rainfall rates exceeding 2 inches per hour will be
possible within stronger cells, which could quickly overwhelm
drainage systems and produce flash flooding, especially in urban,
low-lying, and poor drainage areas. WPC continues to highlight
much of our CWA within a Slight Risk (level 2 of 4) for excessive
rainfall/flash flooding for the rest of today through Wednesday.
However, an upgrade to a Moderate Risk (level 3 of 4) has become
necessary, particularly for Monday, as confidence in heavier
coverage has increased. All of this has prompted the issuance of a
Flood Watch beginning tonight and continuing through Tuesday
evening.

Temperatures will trend slightly cooler through midweek due to
increased cloud cover and precipitation. However, any locations that
receive limited rainfall could still experience periods of heat
indices exceeding 103 to 107 degrees during the afternoon hours. By
late week, rain chances are forecast to gradually decrease from west
to east as deeper moisture shifts away from the region and weak
ridging begins to rebuild. Stronger subsidence should allow
temperatures and heat indices to trend upward again heading into
next weekend, potentially resulting in elevated heat risk conditions.

As far as coastal hazards go, long-period swells around 6-8 seconds
and seas of 4-5 feet combined with astronomically higher tides due
to the new moon phase will lead to hazardous marine and beach
conditions. This includes a heightened risk for rip currents and
minor coastal flooding concerns during times of high tide through at
least tonight/early tomorrow.

.AVIATION...
(18Z TAFS)
Issued at 154 PM CDT Sun Jun 14 2026

Widespread showers and storms will continue to move through South
Texas over the next several hours. Chances subside slightly late
this evening before another wave of precipitation arrives overnight
tonight. PROB30 groups were utilized to denote this potential.
Expect for mainly VFR conditions to prevail until very early
tomorrow, but any heavier showers or storms will have the
capabilities of briefly reducing CIGS and VSBYs to MVFR/IFR levels.
East-southeasterly winds generally around 5-10 knots will continue
this cycle with occasional gusts up to 20-25 knots in stronger
showers or storms.

.MARINE...
Issued at 154 PM CDT Sun Jun 14 2026

A moderate to fresh (BF 4-5) onshore flow will persist through much
of the period. A Small Craft Advisory is in effect until 4PM, when
Small Craft Exercise Caution conditions will take over and continue
through early in the week. Scattered to numerous showers and
thunderstorms are expected through midweek next week, with locally
heavy rainfall, frequent lightning, and brief gusty winds possible
in and around any stronger storms. Small Craft Advisory conditions
are likely again during the second half of the week as winds are
expected to reach fresh to strong (BF 5-6) levels and seas are
forecast to increase up to 7-9 feet.
