1056 PM CDT Sun Apr 26 2026
Areas affected...Far northeast Oklahoma and far northwest Arkansas
Concerning...Tornado Watch 153...
Valid 270356Z - 270530Z
The severe weather threat for Tornado Watch 153 continues.
SUMMARY...Local extensions of WW 152 may be needed based on the
evolution of convection across far northeast Oklahoma and
north-central Oklahoma over the next hour.
DISCUSSION...With the recent demise of a supercell near the
Bartlesville, OK area, the short-term severe threat across WW 152 is
now primarily confined to far northeast OK where convection
continues to intensify on the western flank of a robust supercell
located in far southeast KS. Although this back building convection
is not ideally located on the storm scale for discrete convection,
it is intensifying within an environment characterized by STP values
of 4-6 per recent mesoanalysis estimates. These estimates seem to be
a valid characterization of the environment based on nearby KINX VWP
observations, which are sampling 0-1 km SRH on the order of 500
m2/s2. Additionally, a weak low-level confluence boundary is noted
draped across northeast OK into far northwest AR with at least one
attempt at new convective development noted near the OK/MO/AR
border. Given the highly favorable shear environment (and reservoir
of nearly 3500 J/kg MLCAPE), severe convection will remain possible
for the next couple of hours across far northeast OK and perhaps far
northwest AR.
Further west, GOES IR imagery depicts an intensifying cell near
Fairview, OK. This intensification appears to be coincident with the
cell crossing a northward advancing warm front, suggesting that it
is now beginning to ingest near-surface parcels. Consequently,
further intensification of this cell is expected, and given the
favorable sheared environment downstream, will likely pose some
tornado concern in the next couple of hours across portions of
north-central OK.
Given these localized convective trends, portions of WW 152 may need
to be extended in time to address the developing concerns.

1037 PM CDT Sun Apr 26 2026
Areas affected...Southwest and South-central Missouri
Concerning...Tornado Watch 153...
Valid 270337Z - 270530Z
The severe weather threat for Tornado Watch 153 continues.
SUMMARY...A tornado threat is expected to continue for several more
hours into the early overnight period across parts of southwest and
south-central Missouri.
DISCUSSION...On water vapor imagery, a vigorous shortwave trough is
evident over the northern Ozarks. Near this feature, scattered
strong to severe thunderstorms are ongoing. Ahead of and to the
south of the storms, moderate instability is analyzed by the RAP in
southwest Missouri. Over the top of the unstable airmass, mid-level
flow is westerly at 40 knots. This is creating shear favorable for
supercells. In addition, the RAP is showing a 30 to 40 knot
low-level jet located over west-central and southwest Missouri. The
WSR-88D VWP at Springfield, Missouri has a looped hodograph with 0-3
km storm-relative helicity near 650 m2/s2. This will continue
support a tornado threat with supercells. Large hail and wind damage
will also be likely with supercells.

Tornado Watch Number 155
NWS Storm Prediction Center Norman OK
940 PM CDT Sun Apr 26 2026
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
Southern Kansas
Western and North Central Oklahoma
* Effective this Sunday night and Monday morning from 940 PM
until 400 AM CDT.
* Primary threats include...
A few tornadoes and a couple intense tornadoes possible
Scattered large hail and isolated very large hail events to 3
inches in diameter likely
Scattered damaging wind gusts to 70 mph likely
SUMMARY...Isolated supercell thunderstorms are expected tonight near
a warm front lifting northward into southern Kansas. These storms
will pose a risk for a few tornadoes (some may be strong), large to
very large hail, and damaging wind gusts. A more conditional risk
exists across western Oklahoma along a retreating dryline. If a
storm develops across this area, a very favorable environment will
support a risk for tornadoes, very large hail, and damaging wind
gusts.
The tornado watch area is approximately along and 130 statute miles
north and south of a line from 70 miles west southwest of Alva OK to
40 miles east southeast of Enid OK. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU5).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and 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 Thunderstorm Watch Number 154
NWS Storm Prediction Center Norman OK
910 PM CDT Sun Apr 26 2026
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Northern Kansas
Northwest Missouri
* Effective this Sunday night and Monday morning from 910 PM
until 400 AM CDT.
* Primary threats include...
Scattered large hail and isolated very large hail events to 3
inches in diameter likely
Scattered damaging wind gusts to 70 mph likely
A tornado or two possible
SUMMARY...Severe thunderstorms will increase from west to east
across the watch area through the nighttime hours. Isolated to
scattered elevated supercell storms will pose a risk for large to
very large hail and damaging wind gusts. If a storm can become
surface based as a warm front lifts northward across
central/southern Kansas, a tornado or two also will be possible. The
the tornado risk is more conditional and uncertain, with the hail
and wind risk expected to be the predominate severe hazard.
The severe thunderstorm watch area is approximately along and 165
statute miles east and west of a line from 55 miles north northeast
of Manhattan KS to 50 miles south southeast of Manhattan KS. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU4).

tornadoes.

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0805 PM CDT Sun Apr 26 2026 Valid 270100Z - 271200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS CENTRAL/EASTERN KANSAS...NORTHERN OKLAHOMA...FAR WESTERN MISSOURI... ...SUMMARY... Scattered severe thunderstorms with large to very large hail, damaging winds and tornadoes are expected tonight across parts of the southern/central Plains to Lower Missouri Valley. A couple of strong tornadoes and hailstones up to 2-3 inches in diameter are possible. ...01Z Update... A prominent shortwave trough now nearing the Colorado/Kansas border is promoting elevated convection ahead of it. An 8.2 C/km mid-level lapse rate was sampled on the 00Z DDC sounding this evening. These steep lapse rates should shift eastward along with the shortwave trough. Additional, stronger convection remains possible in parts of central/eastern Kansas into northern Oklahoma. Earlier convection has complicated the low-level thermodynamic environment, though large hail and damaging winds are possible with organized cells and linear structures. The tornado threat through the evening is somewhat less clear, but a deepening surface low should advect richer moisture northward. Depending on storm mode and low-level stability, tornadoes remain possible in parts of northern Oklahoma and south-central Kansas later this evening. In the short term, the greatest threat for a strong tornado is in southeast Kansas. In Oklahoma into North Texas, the dryline is surging westward. This area will become increasingly removed from large-scale ascent. An isolated storm or two remain possible at least trough mid-evening. Lastly, convection in Missouri and southeast Kansas will eventually grow upscale. A buoyancy gradient within the Mid-South region may serve as a focus for continued southeast movement through the evening. Marginal wind and hail are possible with this activity. ..Wendt.. 04/27/2026Read more
