Mesoscale Discussion 0040
NWS Storm Prediction Center Norman OK
0129 AM CST Sat Jan 24 2026
Areas affected...Northwest/Southwest/North-Central
TX...South-Central/Southeast OK
Concerning...Winter mixed precipitation
Valid 240729Z - 241130Z
SUMMARY...A mix of freezing rain and sleet is expected to persist
from southwest Texas into north-central Texas and
south-central/southeast Oklahoma throughout the morning.
DISCUSSION...Surface observations around the region currently place
the freezing line from Bonham (in Fannin County TX) southwestward
through northwest Tarrant County before diving more
south-southwestward through San Saba, TX. This orientation puts much
of the DFW Metroplex just above freezing, with some temperatures
actually increasing a degree or two amid light precipitation and
resultant wet bulbing. Even so, continued cold-air advection is
anticipated, with temperatures eventually dropping below freezing
later this morning. Those areas already below freezing will also see
temperatures continue to decrease throughout the morning.
Current regional radar imagery shows some banding across
north-central TX (northwest of the Metroplex), where strong 850mb
warm-air advection is ongoing. Correlation coefficient from KFWS
suggests most of this is sleet. Additionally, a large area of light
precipitation continues to build upstream of the region amid modest
lift attendant to a subtle lead shortwave trough and continued
isentropic ascent. Expectation is for precipitation to continue
across this region for the next several hours, with sleet as the
prominent p-type across southwest/northwest TX and south-central OK.
Freezing rain will likely become more common across north-central TX
over the next hour or two, with another transition to sleet possible
later this morning as the surface continues to cool.

Mesoscale Discussion 0039
NWS Storm Prediction Center Norman OK
0118 AM CST Sat Jan 24 2026
Areas affected...Far Eastern Oklahoma...Central and Northern
Arkansas.
Concerning...Winter mixed precipitation
Valid 240718Z - 241115Z
SUMMARY...Heavy snowfall, with rates up to 1 inch per hour, are
expected to develop from parts of far eastern Oklahoma eastward
across much of central and northern Arkansas over the next several
hours. The snow should be mixed with sleet over parts of central
Arkansas.
DISCUSSION...The latest water vapor imagery shows a mid-level trough
in the western U.S., with a belt of strong zonal westerly flow over
much of the central and eastern U.S. Lift is currently maximized
over the Ark-La-Tex and southern Ozarks, where a shortwave trough
appears to moving through the flow, and the right exit region of an
expansive mid-level jet is located. Within this zone, radar shows a
large area winter precipitation, which is organized into an
east-to-west band. This band is being supported by strong lift
associated with the northern edge of a 35 to 45 knot low-level jet.
As the low-level jet shifts eastward across south-central Arkansas
over the next 3 to 6 hours, isentropic lift will become maximized in
parts of central and northern Arkansas. Snowfall rates are expected
to peak near 1 inch per hour within the heaviest part of the band.
On southern edge of the band, a sleet/snow mix is expected. The
potential for heavy precipitation should continue over the next four
to six hours.

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF
THE EASTERN GULF COAST...
CORRECTED FOR GRAPHIC ERROR
...SUMMARY...
Strong to severe thunderstorms are possible across parts of the
eastern Gulf Coast states Sunday into Sunday night. Damaging gusts
are expected to be the primary risk.
...Synopsis...
A broad positively tilted larger-scale mid-level trough over the
central US is forecast to intensify Sunday as it moves eastward and
absorbs several smaller perturbations ejecting from the Rockies and
western CONUS. The most prominent of these smaller-scale features
will move from the Sabine Valley and central Gulf Coast,
northeastward into the Tennessee Valley and central Appalachians by
Monday night. Amplification of the overall trough and southwesterly
cyclonic flow aloft will support the development of a weak surface
low ahead of the cold front moving into the Southeast. Southerly
flow ahead of this low will result in modest modification inland of
a remnant Gulf air mass south of a large Arctic intrusion/cold air
damming. Weak buoyancy and strong forcing will likely support a band
of thunderstorms with the potential for some strong/severe storms
through parts of the eastern Gulf Coast Sunday afternoon.
...Eastern Gulf Coast States...
Gradual destabilization is expected early Sunday first over southern
LA and MS as the surface low and warm front lift northward. Strong
isentropic ascent over the shallow Arctic air mass will likely
support a band of initially elevated convection from portions of
East TX into southern LA and MS gradually spreading eastward. With
time, these storms will encounter the northward advancing modified
warm sector as the cold front impinges on the western edge of the
moisture return through the day.
Weak destabilization peaking around 500-750 J/kg of MLCAPE will
overlap with strong deep-layer shear of 50-60 kt. This will allow
for some intensification/organization of the ongoing storms where
the near surface air mass can destabilize. Likely linear in nature
owing to the strong frontal forcing, a few stronger segments appear
plausible, especially across southeastern Alabama and the Florida
Panhandle into southwestern Georgia late Sunday afternoon and
evening. Damaging gusts would be primary risk given 50-70 kt flow in
the lowest 1-3 km AGL. A brief QLCS tornado is also possible, but
less certain as the low-level wind field gradually veers through the
day as the main ascent lifts away to the north.

...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms appear unlikely Monday.
...Synopsis...
Mid-level troughing and strong cyclonic flow aloft will shift
southward over the US before gradually moving offshore Monday. A
second trough is expected to move south out of Canada into the Great
Lakes as it also intensifies. The mid-level flow pattern is forecast
to continue to amplify with troughing persisting over the eastern
US. In turn, ridging is forecast to build over the central and
western portions of the country with increasingly strong
northwesterly flow.
At the surface, a robust and widespread Arctic air mass with strong
high pressure will dominate the lower 48 as a cold front moves
offshore into the Atlantic and down the FL Peninsula. Widespread
winter weather and cold temperatures will largely preclude robust
inland surface moisture outside of coastal south FL. However, weak
lapse rates and only glancing ascent suggests thunderstorm potential
here is low. Thus, thunderstorms and severe weather appear unlikely
over the US on Monday.
