The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Southwest Arkansas
Northwest Louisiana
Southeast Oklahoma
Northeast Texas
* Effective this Saturday night and Sunday morning from 1010 PM
until 600 AM CDT.
* Primary threats include...
Scattered large hail likely with isolated very large hail events
to 2 inches in diameter possible
Scattered damaging wind gusts to 70 mph possible
A tornado or two possible
SUMMARY...Isolated to scattered thunderstorms will continue to track
southeast into the overnight hours. Nocturnal cooling and increasing
boundary-layer inhibition will limit surface-based storms and large
hail up to 2 inch diameter will be the main hazard. Isolated severe
gusts also are possible. If a storm can become surface-based, a
tornado is also possible.
The severe thunderstorm watch area is approximately along and 65
statute miles north and south of a line from 60 miles southwest of
De Queen AR to 35 miles east of El Dorado AR. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU7).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.

MD 0542 CONCERNING SEVERE THUNDERSTORM WATCH 147... FOR NORTHEASTERN TEXAS...SOUTHWESTERN ARKANSAS...NORTHWESTERN LOUISIANA
Mesoscale Discussion 0542
NWS Storm Prediction Center Norman OK
1142 PM CDT Sat Apr 25 2026
Areas affected...northeastern Texas...southwestern
Arkansas...northwestern Louisiana
Concerning...Severe Thunderstorm Watch 147...
Valid 260442Z - 260645Z
The severe weather threat for Severe Thunderstorm Watch 147
continues.
SUMMARY...Severe threat continues within WW147.
DISCUSSION...A pair of supercells continue to track south and east
southeastern Arkansas. These cells have a history of producing hail
up to 2.75 inches in diameter and continue to have high MESH cores.
In the short term, these will pose the greatest severe risk with the
primary threat being large to very large hail. While these storms
are likely elevated, should they be able to continue southward into
the warmer air and vicinity of more backed surface flow, a tornado
could be possible.
CAM guidance seems to suggest that eventually, storms will cluster
and move across northern Louisiana through the morning. This may
lead to a shift in potential for strong to severe wind. Given the
diurnal stabilizing of the boundary layer, winds may not make it to
the surface keeping this threat isolated.

MD 0541 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR NORTH-CENTRAL TEXAS
Mesoscale Discussion 0541
NWS Storm Prediction Center Norman OK
1031 PM CDT Sat Apr 25 2026
Areas affected...north-central Texas
Concerning...Severe potential...Tornado Watch likely
Valid 260331Z - 260500Z
Probability of Watch Issuance...95 percent
SUMMARY...A mature supercell continues to track southward in WW144.
A new watch will likely be needed soon.
DISCUSSION...A mature supercell with a history of tornadoes and hail
up to baseball size continues to track southeast near the Ft. Worth
area. This supercell will likely continue given the favorable very
unstable and highly sheared environment across central/eastern
Texas. VAD profiles from KFWS show 0-1km SRH around 350 m2/s2 with
large clock-wise curvature in the low levels. The threat for large
to very large hail and tornadoes will continue with this storm. A
new watch will likely be needed to replace portions of WW144 and
extend further south.

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0800 PM CDT Sat Apr 25 2026
Valid 260100Z - 261200Z
...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
SOUTHEAST OKLAHOMA AND FAR NORTHEAST TEXAS...
...SUMMARY...
Severe thunderstorms with a potential for large to very large,
tornadoes and severe wind gust will continue this evening into
tonight across parts of the southern Plains and Ark-La-Tex.
Additional severe storms with hail and isolated severe gusts will be
possible in parts of the central Plains.
...Southern Plains/Ark-La-Tex...
A low-amplitude mid-level shortwave trough is evident on water vapor
imagery from east-central Kansas southward into west-central
Oklahoma. At the surface, a moist airmass is located over the
eastern part of the southern Plains into the Ark-La-Tex, where
surface dewpoints are in the mid 60s to the mid 70s F. The RAP shows
strong instability across north Texas and southern Oklahoma, with
MLCAPE in the 3000 to 4000 J/kg range. Scattered severe storms are
ongoing near an instability maximum that is near the Red River north
of the Dallas/Fort Worth Metroplex. The RAP is also showing very
steep mid-level lapse rates over southern Oklahoma and far north
Texas. 700-500 mb lapse rates are estimated to be in the 7.5 to 8
C/km range. This will be favorable for large to very large hail.
Hailstones of 2 to 3 inches in diameter will be possible with the
more intense supercells.
In addition, a low-level jet is analyzed from northeast Texas into
eastern Oklahoma. The low-level jet has not strengthened as much as
was originally forecast, but is still expected to gradually ramp up
over the next few hours. This will increase low-level shear
maintaining a tornado threat. The RAP still increases 0-3 km
storm-relative helicity into the 350 to 400 m2/s2 range within a
couple of hours, suggesting that a potential for strong tornadoes
will continue. A wind-damage threat is also expected to be
maintained this evening into the early overnight period, as a severe
convective cluster moves southeastward toward the Ark-La-Tex.
Concerning the placement of the Moderate, it appears that severe
threat coverage will be more limited north of I-40. For this reason,
the northern extent of the Moderate Risk area has been trimmed.
...Central Plains...
Water vapor currently shows a subtle shortwave trough moving into
the mid Missouri Valley and another one moving into the central High
Plains. At the surface, a moist airmass is located from central and
eastern Kansas into far southeast Nebraska, where scattered
thunderstorms are ongoing. Across this area at mid-levels, flow is
generally from west to southwest at 30 to 40 knots. This is creating
sufficient deep-layer shear for organized severe storms. Steep
mid-level lapse rates will be favorable for isolated large hail.
Severe wind gusts will also be possible.
