...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE SOUTHEAST AND EASTERN GULF COAST VICINITY...

...SUMMARY...
Strong thunderstorm development, accompanied by at least some risk
for severe weather, may continue through the day into Sunday night
across parts of the Southeast and eastern Gulf Coast region.

...Parts of the Southeast/Gulf Coast...
No major changes have been made to the Marginal Risk area. 

A QLCS may be ongoing Sunday morning from southeast LA into southern
MS and far southwest AL, as an initially vigorous mid/upper-level
trough/low and surface cyclone move eastward across a gradually
moistening environment. Some threat for locally damaging wind and a
brief tornado may accompany this QLCS Sunday morning, though scant
buoyancy and a tendency towards gradual dampening of the primary
shortwave trough and surface cyclone may result in a weakening trend
with the initial QLCS. 

Despite the expected weakening trend, deep-layer flow/shear across
the warm sector will remain favorable for organized convection, and
continued low-level moistening may allow for deep convection to
redevelop near the Gulf Coast. Destabilization will likely remain
limited, but if sufficient buoyancy can be maintained, then some
threat for locally damaging wind and/or a tornado could evolve
across south AL/GA and the FL Panhandle into the afternoon, and
potentially spread into parts of the FL Peninsula by Sunday night.

Another area of storm redevelopment may evolve across parts of MS/AL
during the afternoon and evening, in association with the primary
midlevel low. The extent of recovery in the wake of the morning QLCS
remains uncertain, but cooling temperatures aloft could support
development of a few strong storms and potentially an isolated
severe threat.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM EAST TX INTO
LA AND SOUTHWEST MS...

...SUMMARY...
Severe thunderstorms are possible from Saturday into Saturday night
from parts of Texas into the lower Mississippi Valley. Isolated hail
will be possible across parts of Texas during the day, with an
increasing threat of damaging winds and a couple tornadoes expected
Saturday night from east Texas into Louisiana and southwest
Mississippi.

...Synopsis...
A vigorous mid/upper-level shortwave trough will move across the
southern Plains during the day, before reaching the lower MS Valley
vicinity Saturday night. This system will be accompanied by a strong
midlevel jet (60-80 kt at 500 mb) and a consolidating surface low
that is forecast to eventually deepen and reach the ArkLaTex region
by evening. Relatively rich low-level moisture (with dewpoints in
the 60s F) will already be in place Saturday morning across parts of
TX/OK, and will eventually spread into parts of the lower MS Valley
by evening, in conjunction with the advancing surface low. 

...Southern Plains into the lower MS Valley...
Elevated storms will likely be ongoing Saturday morning from parts
of west/northwest TX into southern OK, which could pose an isolated
hail threat. Early-day convection may gradually evolve into a
loosely organized QLCS across north TX and vicinity, with additional
isolated strong to severe storm development possible into central TX
as the primary mid/upper shortwave trough ejects eastward. Weak to
locally moderate buoyancy and increasing deep-layer shear will
support at least an isolated severe threat through the afternoon,
though CAM guidance varies regarding the coverage and duration of
organized storms through the first part of the period. 

Guidance generally depicts increasing low-level mass response
near/after 00Z, which should aid the development of a more organized
QLCS during the evening across parts of east TX. This QLCS is
expected move eastward into parts of LA and lower MS Valley during
the late evening and overnight hours. While instability will become
increasingly scant with eastward extent, strengthening low/midlevel
flow and effective SRH will support development of one or more
organized bowing segments, with an attendant threat of scattered
damaging winds. Some increase in the tornado threat will also be
possible Saturday evening/night, both with line-embedded
mesovortices, and also potentially with any supercells within the
warm-conveyor belt region that eventually merge into the primary
QLCS. 

Most guidance suggests some weakening trend prior to 12Z Sunday
morning, with the stronger forcing potentially becoming displaced
from the effective warm sector. However, some threat for locally
damaging winds and a brief tornado could persist near the LA/MS
coasts through the end of the forecast period.

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE SOUTHERN PLAINS...

...SUMMARY...
Isolated strong to severe thunderstorms may produce occasional hail
and gusty winds this evening into the overnight hours across parts
of the southern Plains.

...Southern Plains...
An upper trough over Baja California late this morning will move
eastward across the Southwest/northern Mexico into the southern
Rockies by early Saturday morning. Gradually strengthening low-level
flow will continue to advect somewhat richer moisture northwestward
from the TX Hill Country (mostly 50s surface dewpoints) into parts
of west TX and western/central OK through the period. Modestly
steepened mid-level lapse rates present will support around 500-1000
J/kg MUCAPE by this evening across the southern High Plains. Various
NAM/RAP forecast soundings show strong effective bulk shear (around
50-70 kt) this evening/overnight as southwesterly mid/upper-level
flow strengthens with the approach of the upper trough, which will
likely support thunderstorm organization.

Isolated thunderstorms should initially develop on the northwest
periphery of the low-level moisture return over parts of northwest
TX and vicinity late this afternoon/early evening with some hail
threat. As large-scale ascent associated with the upper trough
approaches the southern High Plains later this evening, a more
extensive southwest to northeast corridor of convection is expected.
One or more clusters may eventually evolve into linear bands and
develop east-northeastward along/near an eastward-moving Pacific
front.

One of these linear clusters with perhaps embedded supercells seems
likely to occur early Saturday morning (after 14/06Z) from parts of
west into northwest TX as stronger forcing for ascent overspreads
this region. Mainly an isolated severe hail risk with the strongest
updrafts this afternoon/evening should transition to a mix of
hail/wind potential during the overnight hours as the convective
mode becomes more linear. Strengthening low-level warm-air advection
over OK tonight will favor primarily elevated strong to locally
severe thunderstorms capable of occasional hail, perhaps extending
as far north as southern KS during the pre-dawn hours Saturday.

...NO CRITICAL AREAS...

...Southeast...
A dry air mass associated with surface high pressure moving into the
Mid Atlantic will support minimum relative humidity as low as 15
percent across portions of the southeast and northern FL today.
Although dry fuels are present, a diffuse surface pressure gradient
will promote light winds of 10 mph or less across much of the
Southeast, limiting a broader fire weather threat. However, brief
and localized elevated fire weather concerns are still possible
across the coastal plains of GA/SC where sustained northeast winds
of 10 mph, relative humidity below 20 percent and dry fuels align.

...Southern Plains...
Increasing mid and upper-level moisture and associated cloud cover 
ahead of a pronounced short wave trough entering the Southwest is
observed overspreading the Southern Plains. At the surface, lee
troughing across the central/southern High Plains continues to usher
in deeper boundary layer moisture from the Gulf into TX/OK. These
factors should largely subdue fire weather concerns today, with
wetting rains expected tonight into Day 2 across much of the
Southern Plains as the short wave ejects into the region.

..Williams.. 02/13/2026

.PREV DISCUSSION... /ISSUED 1214 AM CST Fri Feb 13 2026/

...Synopsis...
A mid-level shortwave trough and associated jet max will traverse
the southwestern CONUS through the day today, bringing mid-level
moisture from the Pacific. Additionally, with the lee troughing
across the southern high Plains, moist air is expected to surge
northward cross the southern Plains. This is expected to promote
widespread precipitation in these regions, minimizing fire weather
concerns. Elsewhere, surface high pressure associated with
northwesterly flow aloft should settle across the eastern CONUS, and
the light winds associated with the high pressure should keep fire
concerns minimal.
