URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 361
NWS Storm Prediction Center Norman OK
1000 PM CDT Sat Jun 20 2026
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Southwest into South-Central Kansas
Northwest Oklahoma
Far Northeast Texas Panhandle
* Effective this Saturday night and Sunday morning from 1000 PM
until 400 AM CDT.
* Primary threats include...
Scattered damaging winds and isolated significant gusts to 80
mph likely
Isolated very large hail events to 2 inches in diameter possible
SUMMARY...A severe squall line will continue southeastward and pose
a risk for severe gusts into the overnight. Gusts ranging from 60
to 80 mph are possible. Large hail may accompany the stronger cores
on the western flank of the squall line.
The severe thunderstorm watch area is approximately along and 65
statute miles north and south of a line from 55 miles south
southwest of Garden City KS to 10 miles northeast of Wichita KS. For
a complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU1).
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.

NWS Storm Prediction Center Norman OK
740 PM CDT Sat Jun 20 2026
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Western into Central Nebraska
* Effective this Saturday night and Sunday morning from 740 PM
until 100 AM CDT.
* Primary threats include...
Scattered large hail and isolated very large hail events to 2
inches in diameter possible
Scattered damaging wind gusts to 70 mph possible
SUMMARY...Isolated to scattered severe thunderstorms are forecast to
pose a risk for large hail and severe gusts through the late
evening. A couple of elevated supercells and a thunderstorm band
moving from west to east will be the primary storm modes with this
activity.
The severe thunderstorm watch area is approximately along and 60
statute miles east and west of a line from 70 miles north northwest
of Mullen NE to 65 miles south southwest of Mullen NE. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU0).

URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 359
NWS Storm Prediction Center Norman OK
720 PM CDT Sat Jun 20 2026
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Central into Northern Kansas
South-Central Nebraska
* Effective this Saturday night and Sunday morning from 720 PM
until 300 AM CDT.
* Primary threats include...
Scattered damaging winds and isolated significant gusts to 80
mph likely
Isolated very large hail events to 2 inches in diameter possible
A tornado or two possible
SUMMARY...Clusters of severe thunderstorms are forecast to move into
the Watch area this evening and continue into the overnight. Severe
gusts will likely accompany the more intense thunderstorms and their
outflow along the leading gust front. Severe gusts ranging from 60
to 80 mph are possible. Large hail may also occur with the stronger
thunderstorm cores. As the low-level jet intensifies this evening
and a linear cluster evolves, a tornado or two is possible that
would be embedded within the squall line.
The severe thunderstorm watch area is approximately along and 85
statute miles east and west of a line from 45 miles east northeast
of Hastings NE to 25 miles west southwest of Hutchinson KS. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU9).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.

Mesoscale Discussion 1220
NWS Storm Prediction Center Norman OK
0942 PM CDT Sat Jun 20 2026
Areas affected...portions of west-central into southern Kansas...the
extreme northeastern Texas Panhandle...and far northern Oklahoma
Concerning...Severe potential...Watch possible
Valid 210242Z - 210345Z
Probability of Watch Issuance...60 percent
SUMMARY...A downstream Severe Thunderstorm Watch issuance is being
considered.
DISCUSSION...A mature cold-pool-driven MCS continues to produce
measured severe gusts across western KS. Both NEXRAD single-site and
MRMS mosaic radar data have shown an uptick in the organization and
intensity of the MCS, with a somewhat increased southeasterly
propagation speed and a well defined rear inflow jet. Given residual
1500-3000 J/kg MLCAPE and 40-50 kts of effective bulk shear ahead of
this MCS, it is plausible that the accompanying wind swath may
potentially cross into far northern OK. As such, a downstream Severe
Thunderstorm Watch issuance will probably be needed given a
persisting strong MCS structure with accompanying measured severe
gusts.

Valid 210100Z - 211200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
KANSAS...
...SUMMARY...
Severe thunderstorms remain likely across parts of the central
Plains this evening into late tonight. Large hail, severe winds
(some 75+ mph), and a few tornadoes are possible.
...Central Plains...
An intense supercell cluster over northwest KS is expected to grow
at least modestly upscale with time this evening, and spread
east-southeastward across parts of northern/central KS, while more
isolated supercells may evolve across southwest KS and move toward
south-central KS through at least dusk. MLCAPE of near/above 2000
J/kg and effective shear of 50+ kt will continue to support
organized storms with large hail (potentially 2+ inches in diameter
with any sustained supercells), severe wind gusts (possibly 75+
mph), and some tornado potential, especially with storms that
persist into richer low-level moisture across central/eastern KS.
Storm evolution remains somewhat uncertain overnight into eastern KS
and western MO, but a storm cluster and possible MCS may continue
through the end of the period, with severe-wind potential, and some
hail and tornado threat with any embedded supercells.
Farther northeast, elevated supercells may continue to pose a threat
of hail and isolated strong to severe gusts from southeast NE into
northeast KS through dusk. See MCD 1215 for more information.
To the west, a cluster of storms with a history of measured severe
gusts is moving into parts of southwest SD and the NE Panhandle.
Increasing CINH with time and eastward extent should result in a
gradual weakening trend, though some severe threat will remain
possible into mid/late evening across the NE Sand Hills region. See
MCD 1218 for more information.
Some threat for isolated supercells may persist farther south into
northeast CO through dusk, with a threat of hail. Other remnant
high-based convection may pose a threat of localized severe gusts
through dusk across parts of western/central WY.
