.DISCUSSION...
Issued at 1246 AM CDT Sat Jun 7 2025

A mid- to upper level ridge will remain the dominant weather feature
across South Texas this weekend, promoting strong subsidence that
will limit vertical motion and significantly reduce the potential
for convection. While an isolated shower or two cannot be completely
ruled out this afternoon near the coast, chances remain very low
(less than 15%). Additionally, the Saharan dust plume that arrived
yesterday will further suppress rainfall and contribute to hazy
conditions. Reduced visibilities of 5-6 miles are expected to
persist throughout the day today.

The ridge will also continue to support hot conditions across the
region through early next week. Temperatures will run 3-8 degrees
above normal, with 850 mb temperatures between 20-25 degC
contributing to widespread afternoon highs in the triple digits west
of the I-37 corridor and the 90s across the remainder of South
Texas. South-southeasterly surface flow will continue to usher in
low-level moisture, further elevating heat stress. Heat index values
are forecast to reach 110-117 degF, leading to a Major to Extreme
risk for heat related impacts. As for our risk today, a few isolated
locations in portions of the Brush Country may briefly approach the
threshold for a Heat Advisory. However, widespread criteria are not
expected as the presence of the aforementioned Saharan dust may keep
actual temperatures slightly lower than model projections. While I
have opted to not issue an Advisory today, confidence is increasing
for more widespread heat impacts on Sunday and Monday.

Regardless of Advisory status/issuance, please continue to practice
heat safety: stay hydrated, limit time outdoors, avoid strenuous
activity during peak heating hours, and always check vehicles for
children and pets!

Heading into early next week, the upper ridge is forecast to shift
westward, allowing weak mid-level disturbances to pass across the
region. This shift in the upper-level pattern, coupled with rising
moisture will lead to low-to-medium (20-60%) rain chances beginning
late Tuesday through much of the next work week. Probabilities are
highest across the Victoria Crossroads where moisture and lift will
be more favorable, with more limited activity expected along the Rio
Grande due to the close proximity of the retreating ridge. The
highest probability of rainfall potential is forecast Wednesday. By
late week, rain chances gradually taper off as the upper-trough
slowly propagates eastward. Increased cloud cover and any rainfall
that occurs throughout the week, will help moderate daytime
temperatures slightly, with highs dropping into the 90s areawide
Wednesday-Thursday.

.AVIATION...
(06Z TAFS)
Issued at 1246 AM CDT Sat Jun 7 2025

Generally VFR conditions expected through the TAF cycle. Haze will
impact all terminals during the TAF cycle, but have only mentioned
this for VCT as most locations will not have a noticeable decrease
in visibility. MVFR ceilings are expected tonight, especially
between 09Z-14Z. ALI is also expected to develop periods of MVFR
visibility during the 09Z-14Z time frame.

.MARINE...
Issued at 1246 AM CDT Sat Jun 7 2025

A moderate to fresh (BF 4-5) onshore breeze can be expected
through next week. A plume of Saharan dust that arrived yesterday
will result in hazy skies this weekend. Low to medium (30-60%) rain
chances return Tuesday and will linger through much of the next
work week.
