.KEY MESSAGES...

- A conditional threat remains for severe thunderstorms capable
  of producing large hail and damaging winds (tornadoes cannot be
  ruled out) tomorrow afternoon/evening along and north of the
  Highway 105 corridor.

- Post-frontal conditions will maintain near to below normal
  temperatures into the weekend, with a likely chance of 1-1.5
  inches of rain areawide by Monday.

- Drier and warmer conditions will return by early next week.

.DISCUSSION...
Issued at 1208 AM CDT Wed May 6 2026

A relatively active weather pattern will continue across
southeast Texas as we sit firmly in the pathway of southwesterly
flow aloft for the rest of the week. This flow is positioned
between broad troughing across the Upper Great Plains and broad
ridging across Mexico into parts of the Gulf. All of this flow is
being amplified (in-part) by a slowly-moving area of low pressure
set to move across the Baja Peninsula. This, in combination with
lift from an incoming frontal boundary through the day on
Wednesday, will present a somewhat favorable spatiotemporal window
for convection across east-central Texas into Deep East Texas.
The "somewhat" comes into play due to a persistently dry 700-850mb
layer that will set a significant convective threshold (or cap)
against the development of severe thunderstorms. High-resolution
guidance picks up on this cap with a rather paltry convective
distribution, however, any storms that can get through the cap
will still have some ingredients to work with (2500+ J/kg of CAPE,
mid-level lapse rates of 7-7.5 C/km, and 30-40+ kts. of bulk wind
shear). Large hail, damaging winds and tornado threats remain on
the table as a result.

Beyond this upcoming window for severe weather in the next 24-36
hours, post-frontal isentropic uplift will be the main convective
theme and source of precipitation through the weekend. With the
area of low pressure still slowly approaching West Texas by
Friday, it will inject overrunning southwesterly flow with
vorticity to instigate more widespread rounds of convection into
Saturday and make this the wettest time period in the current
forecast range. WPC Day 1-7 QPF forecasts of 1-1.5 inches are
mostly from this round of rainfall. Long-range guidance suggests a
drier and warmer period (temperature maximums/minimums in the
mid-to-upper 80s/upper 60s) by Monday as the next frontal
boundary arrives and the area of low pressure finally weakens and
shifts eastward into Louisiana.

.AVIATION...
(00Z TAF Issuance)
Issued at 642 PM CDT Tue May 5 2026

MVFR ceilings will begin to gradually filter in over the evening
hours and eventually becoming widespread by 06Z/Wednesday. There
is potential for IFR ceilings early Wednesday morning, especially
for terminals north of I-10. Cannot entirely rule out some patchy
fog for CXO and terminals northward between 11Z-15Z. MVFR ceilings
are expected to stick around through the entire day. Going into
Wednesday morning, scattered showers will begin developing along
the coast as early as 12Z and expanding over inland areas around
18Z. There is potential for isolated thunderstorms mainly after
21Z for terminals north of and including CXO, but the potential is
too low to include in any of those TAFs at this time. Winds will
be southerly and generally less than 10 kt. The exception to this
is CLL and UTS where a frontal boundary will begin pushing into
the area in the afternoon leading to a northerly wind shift. Winds
will remain on the light side behind the front. Ceilings will
gradually decrease again going into Wednesday evening.

.MARINE...
Issued at 1208 AM CDT Wed May 6 2026

Onshore flow will maintain some brief activity for seas with light
to moderate swells in the next 24 hours ahead of a frontal
boundary. Once the frontal boundary is offshore by Thursday,
showers and thunderstorms are more likely (30-50% chance of
development), especially by Friday into Saturday. Post-frontal
northerly to northeasterly winds are expected to remain below the
threshold requiring issuance of a Small Craft Advisory, however,
wind speeds could still exceed 20 kts. overnight Thursday further
offshore into the Gulf. Long-range guidance suggests another
chance of post-frontal showers/thunderstorms offshore beginning
later on Sunday.
