(Today through Friday)
Issued at 313 AM CDT Thu Jun 13 2024

The recent active weather pattern will largely come to an end today
as the subtropical ridge axis over northern Mexico into the desert
southwest begins to build into the region. We will add some low rain
chances to the coastal plains this afternoon as at least a few of
the hi-res models show some convection developing during peak
heating. We are also noting some weak cyclonic circulation in water
vapor imagery over western Texas. We will continue to monitor this
as it continues to move southward today. For now, we will not
mention any convection outside of the coastal plains, but it is
worth monitoring. Otherwise, expect temperatures to remain at or
above normal, ranging from the lower 90s to near 103 degrees.
Overnight lows will range from near 70 to near 80 degrees as skies
remain mostly clear. We will keep the forecast dry across all areas
on Friday as highs inch upward a degree or two from what we are
forecasting today.

.LONG TERM...
(Friday night through Wednesday)
Issued at 313 AM CDT Thu Jun 13 2024

A shortwave moving to the northeast over the Plains this weekend
will create a weakness in the Subtropical Ridge over Texas by
Sunday. A plume of tropical moisture initially spreads north to over
eastern parts of our area. The seabreeze will become active Sunday
and each day through at least mid week. Low chances of showers and
thunderstorms return to near the Coastal Plains on Sunday, then west
to the I-35 corridor on Monday and Tuesday. Models are increasing
the potential for development of a tropical system with NHC now
indicating a 40% chance in the southwestern Gulf of Mexico. Whatever
develops, models have a consensus in taking the system into Mexico
as the Subtropical Ridge begins to re-strengthen over Texas. The
moisture plume shifts toward the west with rain chances spreading to
the Rio Grande on Wednesday into Thursday. Enhanced rainfall may
become possible near the Coastal Plains early in the week, then
across the southern parts of the Rio Grande Plains later in the
week. Seasonably hot temperatures and humid conditions are expected.

.AVIATION...
(18Z TAFS)
Issued at 1146 AM CDT Thu Jun 13 2024

A rather quiet forecast compared to the last several days as TS is
not expected through the day today. Some VCSH was added at SAT and
SSF to account for weak convection developing along a boundary
situated over the central portion of the CWA. VFR CIGs and Visby`s
can be expected through the period. Winds should generally remain
less than 10 kts and transition back and forth from eastern to
southerly. There is an outside shot at some MVFR CIGs at SAT and SSF
after sunrise Friday, but confidence is too low to include in the TAF
at this time.
