.DISCUSSION...
Issued at 1200 PM CDT Fri May 15 2026

As the ridge continues to progress to the east through tomorrow, we
will have strong return flow into the region. The pattern will begin
to shift as we have a trough digging around the Four Corners region
digging south and extending into West Texas/Northern Mexico. This
will send a series of mid-level shortwave disturbances into our
region. In addition to this, deep Pacific moisture will also be
pumped into the region increasing PWATs to around 2.0", well above
normal for this time of year climatologically speaking (99th
percentile). Guidance is in pretty good agreement that the area will
receive rain. How much each part of the area will get will be
decided on how the shortwaves track through the region. As of now,
the LREF is continuing to maintain high confidence that all of South
Texas will receive 1" of rainfall (60-75%) through next Saturday.
Will continue to monitor the trends in regards to this due it still
being a few days out.

Heat stress conditions will be another byproduct of the influx of
moisture in the region. The increased moisture will lead to very
warm dew points and increased cloud cover. This will not allow for
temperatures to recover effectively overnight leading to warm
overnight lows and warmer highs during the day. Confidence is
increasing for heat indices around 100-110 degrees from Saturday
through mid-next week. We strongly encourage the practice of heat
safety in these conditions. Take frequent breaks and remember to
stay hydrated, check those backseats, and avoid long exposure in
these temperatures. For more information be sure to check out
weather.gov/heatsafety.

P-ETSS guidance is portraying tide levels potentially 2.0 ft MSL
late this weekend. This would also coincide with the new moon
beginning Saturday and likely increased winds with greater swells.
This will lead to minor coastal flooding and increased risk of rip
currents through early next week.

.AVIATION...
(00Z TAFS)
Issued at 628 PM CDT Fri May 15 2026

VFR conditions currently prevail under cirrus clouds with breezy
southeasterly winds sustained at 15-20 knots and gusts up to 30
knots over the Coastal Plains. Stronger LLJ tonight over the Brush
Country will promote MVFR ceilings to develop, mainly between
09-15Z. Less confidence of MVFR ceilings elsewhere but included
TEMPO groups for VCT/CRP/ALI. Winds will remain strong enough to
negate fog development. Southeasterly winds restrengthen Saturday
morning to 15-20 knots sustained and gusts 25-30 knots again.

.MARINE...
Issued at 1200 PM CDT Fri May 15 2026

Southeasterly moderate to fresh (BF 4-5) breeze today and persist
into the middle of next week. A Small Craft Advisory is in effect
this afternoon through early Saturday morning for the bays and
nearshore waters south of Port Aransas. An extension or/and
expansion of the advisory may be necessary as we progress through
the weekend. There are low to medium rain chances beginning daily on
Tuesday next week.
