...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM EAST TEXAS TO
CENTRAL ALABAMA...
...SUMMARY...
Scattered severe thunderstorms are forecast across southeast Texas
into the central Gulf states tonight. A few tornadoes and damaging
wind gusts are possible.
...01z Update...
Notable short-wave trough is beginning to eject northeast across the
central Plains early this evening. Water vapor supports this with
the center of circulation near DDC. 500mb speed max affiliated with
this feature will strengthen and translate across north TX-southern
MO-central IN by the end of the period. This evolution will result
in negligible height changes along/near the Gulf coast overnight.
As this feature advances east, LLJ is expected to increase across LA
later this evening, strengthening into northern AL by 10/12z.
Low-level warm advection has proven instrumental in convective
development much of the day with scattered thunderstorms persisting
across the lower MS Valley. However, some increase in convection
appears to be occurring across east TX as the southern influence of
the ejecting short wave glances this region. Earlier thoughts
regarding severe potential remain. 00z sounding from LCH exhibits
strong shear and ample buoyancy for supercells. Latest thinking is
scattered-numerous showers/thunderstorms will persist along a
corridor from northern LA into central MS with the potential for
some uptick in intensity overnight as the LLJ strengthens.

MD 0015 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PARTS OF THE LA INTO SOUTHERN/CENTRAL MS AND SOUTHWEST AL
Mesoscale Discussion 0015
NWS Storm Prediction Center Norman OK
0346 PM CST Fri Jan 09 2026
Areas affected...Parts of the LA into southern/central MS and
southwest AL
Concerning...Severe potential...Watch unlikely
Valid 092146Z - 092315Z
Probability of Watch Issuance...20 percent
SUMMARY...A gradual increase in the tornado threat is possible into
early evening. Damaging wind and isolated hail are also possible.
Watch issuance through the remainder of the afternoon appears
unlikely, but a Tornado Watch will likely be needed at some point
this evening.
DISCUSSION...Scattered thunderstorms are ongoing this afternoon from
LA into southern MS, within a seasonably warm/moist and moderately
unstable environment. Deep-layer shear is strong region-wide, but
convection has largely remained disorganized thus far, likely due to
generally weak ascent and the presence of a warm nose around 700 mb
noted in 18Z soundings from LIX and LCH.
With time, ascent associated with an approaching mid/upper shortwave
trough may support increasing storm organization from late afternoon
into the evening. Low-level flow/shear (which has generally weakened
this afternoon) will also increase in response to the approaching
shortwave, though any more substantial strengthening may not occur
until later this evening.
The current expectation is for a gradually increasing threat of more
organized clusters and a few supercells from late afternoon into the
evening, accompanied by some tornado and wind-damage threat, and
potentially isolated hail. Watch issuance through the remainder of
the afternoon appears unlikely, but Tornado Watch issuance will
become increasingly likely with time into this evening, due to the
anticipated strengthening of the low-level wind profile.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0341 PM CST Fri Jan 09 2026
Valid 111200Z - 171200Z
...Synopsis...
Dry conditions and gradually warming temperatures will likely
dominate the western U.S. under a relatively stagnant upper-level
ridging pattern across the region. Broad northwest flow and
upper-level troughing across the eastern U.S. will continue to usher
in periods of colder temperatures and some precipitation via frontal
systems through late next week, although the High Plains should
remain largely dry.
...Southern/Central High Plains...
A dry return flow pattern should materialize early next week across
the Southern Plains as surface high pressure settles into the
southeastern U.S. Although dry conditions will persist, surface
winds from the west/southwest should remain muted, limiting a
broader fire weather threat. A more amplified upper-level pattern
should emerge by Day 6/Wednesday accompanied by a broad cold front
across the central U.S. This could present a fire weather concern
for portions of the Southern Plains/TX. Increasing northwest flow
aloft over the central/southern Rockies by Day 7/Thursday and
another potential cold front will promote a favorable downslope wind
set up in the lee of the central/southern Rockies. Some uncertainty
in frontal timing limits predictability at this time with no
critical probabilities introduced.
...Day 3/Sunday - Southeast...
Considerable rainfall associated with an upper-level trough and
surface cold front over the weekend will likely mitigate fire
weather concerns from the northern Gulf Coast into the Mid Atlantic
for early next week. However, portions of southern Georgia, Coastal
Plains of the Carolinas and Florida could evade heavier rainfall.
This region could be exposed to dry, post-frontal flow from the
northwest on Day 3/Sunday although marginal fuels precludes
introduction of critical probabilities at this time.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM SOUTHEAST
TEXAS TO THE CENTRAL GULF STATES...
...SUMMARY...
Scattered severe thunderstorms are forecast across southeast Texas
into the central Gulf states. A few tornadoes, damaging wind gusts,
and large hail are possible through tonight.
...20Z Update...
A stronger storm has evolved out of activity in central Texas. This
activity is occurring along a buoyancy gradient along the surface
boundary. While storms will likely remain elevated, a strong to
severe storm or two may be capable of marginally severe hail. The
Marginal has been adjusted to account for this potential.
Additionally, the Slight risk has been moved slightly southward in
central Mississippi given persistent northerly winds and drying low
levels in northern portions of the state. See the previous forecast
for additional details.
..Wendt.. 01/09/2026
.PREV DISCUSSION... /ISSUED 1030 AM CST Fri Jan 09 2026/
...Southern LA northeastward into MS/AL this afternoon...
A southerly fetch of fully modified Gulf air (surface dewpoints near
70 deg F) within a weak but persistent warm-air advection regime
over the central Gulf Coast will probably yield a continuation of
isolated to scattered thunderstorms through the afternoon. Some
breaks in the stratus will promote additional heating of the moist
and weakly unstable airmass. Some weakening of low-level shear has
been observed this morning via the Jackson, MS and Hammond, LA
WSR-88D VADs, and this trend may continue through the mid afternoon
before strengthening later today and into tonight. In the meantime,
an isolated threat for damaging gusts and perhaps a brief tornado
may continue with a stronger storm or two.
...TX/LA/MS/AL this afternoon into the overnight...
Visible-satellite imagery this morning shows an extensive
multi-layer shield of clouds across south-central TX northeastward
into western LA. Ahead of a larger mid-level trough moving east
across the southern Rockies into the southern Plains, a couple of
minor disturbances embedded within strong southwesterly flow are
forecast to move northeastward from TX into the lower MS Valley. In
the low levels, a quasi-stationary front will serve as the northwest
delimiter of the moist/unstable sector before gradually moving
southward across east TX into the Ark-La-Miss later tonight. The
air mass southeast of the front will destabilize this afternoon,
leading to eventual scattered thunderstorms with MLCAPE of 1000-1500
J/kg. This initial activity later this afternoon over TX into LA
will gradually shift eastward into LA/MS this evening and MS/AL
during the overnight. Ample deep-layer shear will pose a risk a few
strong/severe storms capable of damaging winds and hail. Towards
the late afternoon over east TX and western LA and especially
through the evening from southwest LA into central MS, 700-mb flow
(per EC model guidance) is forecast to intensify. This
strengthening of the low to mid-level flow and enlarging of the
hodographs will probably coincide with the primary period of concern
for severe storms. A few supercells capable of a tornado risk will
be the main hazard. However, a threat for scattered damaging gusts
accompanying other organized storm structures and possibly a hail
threat will also continue into the overnight.

...South-Central Texas and Edwards Plateau...
A dry, post-frontal environment will be in place across the Southern
Plains for Day 2/Saturday as an upper-level trough progresses
eastward and surface high pressure builds into the region. Current
observations and short term model guidance suggests showers and
thunderstorms evolving from late Day 1/Friday through early Day
2/Saturday will remain largely east of the eastern extent of
existing elevated highlight area across central TX. Farther west,
dry conditions including single digit surface dew points and RH
values as low as 15%, combined with broad northerly post-frontal
flow of 10-15 mph (locally sustained 20 mph ) will promote a few
hours of heightened fire weather concern in south-central TX and
Edwards Plateau Saturday afternoon. Fire weather concerns diminish
late Saturday afternoon and evening as winds relax and colder
temperatures in the 30s settle into region.
..Williams.. 01/09/2026
.PREV DISCUSSION... /ISSUED 0157 AM CST Fri Jan 09 2026/
...Synopsis...
Mid-level troughing will intensify as it moves eastward across the
central US D2/Saturday. In the wake of the trough, a cold front will
sweep southeastward through the Plains. A dry post-frontal air mass
will develop over much of the Plains, with the driest portions
expected across parts of south-central TX and the Rio Grande Valley.
Gusty northerly winds of 20-25 mph will overlap with the dry air
mass likely supporting elevated fire-weather conditions over
portions of south-central TX and the Big Bend Region Saturday
afternoon.
As the front moves eastward, there is some uncertainty regarding how
far west thunderstorms will form overnight D1/Friday into early
D2/Saturday. Locally elevated fire-weather conditions may briefly be
possible farther east if significant rain does not fall. However,
the most likely corridor is farther west toward the Big bend region
where the strongest winds and lowest RH are expected to persist.
Fire-weather concerns will quickly abate near sunset as a cooler air
mass enhances RH recoveries and winds slacken.

An amplified midlevel trough will advance eastward across the
Northeast and Mid-Atlantic through the period. Strong forcing for

could result in an isolated lightning flash with low-topped
convection overspreading the Mid-Atlantic. However, low confidence
in this scenario and expected limited coverage precludes a TSTM area
at this time. Upstream, an expansive cool/dry air mass will limit
thunderstorm potential across the CONUS.

DISCUSSION...Moderate to heavy snowfall exceeding 1.0 inches/hour is
currently occurring across portions of western/southwestern Kansas
in the presence of surface cold air advection and 700mb

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE SOUTHEAST...
...SUMMARY...
A few severe thunderstorms are forecast on Saturday across the
central Gulf Coast and Southeast.
...Central Gulf Coast into the Southeast...
Along and south of an outflow-reinforced cold front extending across
central AL into southern MS, scattered thunderstorms will be ongoing
across the central Gulf Coast into the Southeast at the start of the
period. These storms will generally be focused along a 30-40-kt
southwesterly low-level jet and ahead of a northeastward-moving
frontal wave.
Despite modest buoyancy, ample boundary-layer moisture (middle/upper
60s dewpoints) and around 50 kt of effective shear will continue to
promote organized storm clusters, to include the potential for a
couple supercells. Damaging winds will be a concern, though enlarged
clockwise-curved low-level hodographs (upwards of 200-250 m2/s2
effective SRH) within the moist axis will yield some risk for a
couple tornadoes as well. The tornado risk will be largely dependent
on the degree of convective overturning in the warm sector. The
window of greatest severe risk appears to be from 12Z-18Z -- before
low-level flow veers ahead of the approaching front and departing
frontal wave. A SLGT risk was added for this corridor of heightened
severe potential.
Thunderstorms will generally spread northeastward across GA into the
Carolinas in tandem with the northeastward-advancing low-level jet
and frontal wave, where they will eventually outpace the
surface-based warm sector during the afternoon.

...Southwest TX and Rio Grande Valley...
A vigorous 70-80 knot mid-level jet over the Permian Basin and TX
Panhandle will accompany an upper trough ejecting into the southern
High Plains through the afternoon, contributing to surface lee
troughing across eastern NM. Efficient boundary layer mixing under
mostly clear skies south of the surface trough and robust mid-level
flow will support downslope-enhanced west winds of 15-20 mph amid
15-20% relative humidity this afternoon across the Permian Basin
region. A swath of 20-25 mph west winds is expected from
southeastern NM into the TX Rolling Plains amid 15% RH, but recent
rainfall should mitigate fire weather threat, with elevated
highlights remaining to the south of higher antecedent moisture
conditions. Elevated fire weather conditions are likely to extend
into central TX/Hill Country this evening as surface flow
transitions to the northwest ahead of a looming secondary cold front
dropping south through Northwest TX. These meteorological conditions
should align with receptive fuels within a region that has seen
minimal rainfall in the last 30 days.
..Williams.. 01/09/2026
.PREV DISCUSSION... /ISSUED 0147 AM CST Fri Jan 09 2026/
...Synopsis...
A potent shortwave trough over the Southwest is forecast to rapidly
move eastward before merging with a broader upper trough over the
central US. A front, trailing from the first trough/low will linger
over the Ozarks and Red River Valley. A weak lee low will develop
and move east as cold front move south. Gusty west/northwest winds
and dry conditions may promote elevated fire-weather potential.
...Southwest TX and Rio Grande Valley...
As the upper trough approaches from the west, large-scale ascent
will support increasing mass response over portions of West TX. As
the weak secondary low deepens over the southern Rockies, strong
southwesterly flow aloft will overspread the remnant warm/dry sector
over parts of Southwestern TX and the Rio Grande Valley. Downslope
winds and diurnal heating should result in low RH around 20% through
the afternoon. Winds will initially be sustained around 15-20 mph,
but eventually the approach of the second cold front will support
increasing gusts to 20-30 mph turning northwesterly. The increasing
winds will overlap with low RH late in the afternoon and into the
evening. Some dry and windy conditions may extended eastward into
the western Hill Country after dark. With dry fuels in place outside
of recent and expected rainfall, several hours of elevated
fire-weather conditions appear probable.

subtle surface warming and moistening sufficient to contribute to
weak boundary-layer based instability, based on forecast soundings
and the 12Z sounding from Jackson. But, this also appears to be
occurring as low-level hodographs shrink and trend more linear, in
the wake of the initial short wave trough now accelerating northeast
of the middle Mississippi Valley. As a result, potential for
further similar mesovortex intensification accompanied by the risk
for a brief tornado and/or damaging wind gusts seems likely to
diminish shortly, if it hasn't already.

...SUMMARY...
Severe thunderstorms are expected across southeast Texas into the
central Gulf states.
...MS/AL This morning...
Multiple clusters of thunderstorms are ongoing this morning across
parts of MS. This activity is in a moist surface air mass with
dewpoints in the mid 60s, and MLCAPE values of 500-1000 J/kg. VAD
profiles suggest sufficient low-level shear for some concern for a
tornado or two this morning as activity tracks northeastward into
western AL. However, model forecast soundings suggest a warm layer
in the 600-700mb layer that is likely limiting updraft strength and
the overall severe risk.
...TX/LA This Afternoon...
Strong, broad southwesterly flow aloft will be present across much
of the southeastern United States today, with several small
perturbations embedded within the flow. A quasi-stationary front is
currently positioned from south TX into southern AR. The air mass
southeast of the front will destabilize this afternoon, leading to
scattered thunderstorm development. MLCAPE of 1000-1500 J/kg and
sufficient deep-layer shear will pose a risk a few strong/severe
storms capable of damaging winds and hail.
...LA/MS This Afternoon/Evening...
By late afternoon, ample daytime heating/destabilization will lead
to scattered thunderstorms over LA, spreading northeastward into MS.
Mid-level lapse rates will be weak, but slowly strengthening
low-level winds and shear will pose a risk of a few severe storms
capable of damaging wind gusts and a few tornadoes.
...Southern MS/AL Overnight...
The consensus of CAM solutions suggest that storms will become
focused along a surface baroclinic zone late tonight from southeast
MS into southern AL. During this period, most models suggest
significant strengthening of the southerly low-level jet, with
forecast hodographs becoming increasingly favorable for supercells
and a few tornadoes - despite marginal thermodynamic support.

Mid-level northwesterly flow is forecast to become established
across the central U.S. on Monday. This appears likely to persist
into mid-week as a large-scale trough develops in the Mississippi
Valley. The pattern will help to usher cold and dry air southward
into the Great Plains and Southeast, which will limit moisture
return. From Thursday into Friday, the trough is forecast to move
into the eastern U.S., reinforcing northwesterly mid-level flow over
much of the nation. As a result, a cold and dry airmass is expected
to remain over the continental U.S, minimizing the potential for
thunderstorm development.

...DISCUSSION...
Mid-level northwesterly flow is forecast to become established
across the central U.S. on Monday. This appears likely to persist
into mid-week as a large-scale trough develops in the Mississippi
Valley. The pattern will help to usher cold and dry air southward
into the Great Plains and Southeast, which will limit moisture
return. From Thursday into Friday, the trough is forecast to move
into the eastern U.S., reinforcing northwesterly mid-level flow over
much of the nation. As a result, a cold and dry airmass is expected
to remain over the continental U.S, minimizing the potential for

...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected to develop across the U.S. Sunday or
Sunday night.
...DISCUSSION...
An upper-level trough will move eastward to near the eastern
Seaboard on Sunday, as northwest flow aloft becomes established
across much of the central and eastern part of the U.S. At the
surface, a large area of high pressure will settle in across the
south-central and southeastern U.S., keeping conditions relative dry
and stable over most of the nation. For this reason, thunderstorms
are not expected to develop over the continental U.S. Sunday and
Sunday night.
