Mesoscale Discussion 1224
NWS Storm Prediction Center Norman OK
1154 PM CDT Sat Jun 20 2026

Areas affected...portions of northeast Colorado

Concerning...Severe potential...Watch unlikely 

Valid 210454Z - 210700Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated thunderstorms capable of producing large hail
will be possible this evening into the early morning hours. The
overall limited space and time of this threat should preclude a
watch. The area will continue to be monitored.

DISCUSSION...Despite the cool nocturnal boundary layer, isolated
supercell thunderstorms have developed across portions of northeast
Colorado this evening. These storms are developing on the nose of an
objective analyzed 70-knot upper-level jet moving across the central
Rockies, and appear to be rooted around 700 millibars per RAP
forecast soundings. One of these supercells produced 2.5" hail
across portions of Logan County, CO, within the last hour before
weakening and eventually dissipating as it moved east. A second
supercell has developed to its southwest across Weld County, CO.
This secondary supercell appears to have undergone a split, with the
left mover remaining nearly stationary over Greeley, CO.
Multi-radar, multi-sensor objective analysis of these storms
suggests hail around 1.5" is possible. 

Although there is a lack of well defined low-level forcing
mechanisms, general large-scale ascent of a moist unstable
environment will support an ongoing threat of thunderstorm
development this evening into the early morning hours. Steep lapse
rates in the 700-500 millibar layer (around 9 C/km) will support
large hail potential with any of these storms, perhaps even
significant (2-2.5") hail. The overall space/time of this potential
should remain fairly limited and a watch is currently not
anticipated. However, should it become apparently that additional
thunderstorm development is likely, a watch may be considered late
this evening/overnight.

Mesoscale Discussion 1223
NWS Storm Prediction Center Norman OK
1147 PM CDT Sat Jun 20 2026

Areas affected...portions of eastern Kansas into far western
Missouri

Concerning...Severe potential...Watch possible 

Valid 210447Z - 210545Z

Probability of Watch Issuance...60 percent

SUMMARY...Severe gusts may persist with ongoing storms for at least
a few more hours as the storms exceed the eastern bounds of ongoing
Severe Thunderstorm Watches 359 and 361. A downstream Severe
Thunderstorm Watch is being considered.

DISCUSSION...A cold-pool-driven bow echo MCS (with mesovortices and
a pronounced rear-inflow jet) continue to track eastward across
central KS, with an uptick in convective intensities noted with line
segments flanking the MCS to the northeast, at the nose of a 700 mb
WAA regime. These storms are poised to continue tracking eastward
amid 1000-2000 J/kg MUCAPE and locally lower MLCINH. Given
widespread 40-50 kts of effective bulk shear (oriented normal to the
MCS leading line) preceding ongoing storms and the aforementioned
buoyancy, it is plausible that a severe gust threat may continue
east of the bounds of Severe Thunderstorm Watches 359 and 361. This
may especially be the case because MLCINH may only slowly increase
in eastern KS given a very moist boundary layer, characterized by
70+ F surface dewpoints. As such, conditions are being monitored for
the need of a downstream Severe Thunderstorm Watch issuance.

1130 PM CDT Sat Jun 20 2026

Areas affected...portions of the Nebraska Sandhills

Concerning...Severe Thunderstorm Watch 360...

Valid 210430Z - 210630Z

The severe weather threat for Severe Thunderstorm Watch 360
continues.

SUMMARY...Thunderstorms continue moving east across portions of
north-central Nebraska this evening. Modest instability and strong
shear should maintain the MCS structure, although weak low-level
lapse rates should keep any severe threat rather isolated.

DISCUSSION...A north-south linear MCS has organized across portions
of north-central Nebraska this evening and will continue eastward
into the morning hours. The overall environment remains
kinematically favorable for thunderstorm organization (effective
layer shear greater than 50 knots), although the thermodynamic
environment remains modest at best with between 500 to 1000 J/kg of
MUCAPE along the line of storms. Additionally, low-level lapse rates
continue to weaken, with 0-3 kilometer lapse rates objectively
analyzed to be around 3 C/km. Thus, despite the linear MCS's
organization, the elevated nature of the individual thunderstorms
and the weak low-level lapse rates should limit any severe wind
potential to being isolated/sporadic in nature.

Areas affected...portions of western into central Kansas

Concerning...Severe Thunderstorm Watch 359...361...

Valid 210424Z - 210600Z

The severe weather threat for Severe Thunderstorm Watch 359, 361
continues.

SUMMARY...Severe gusts will remain a concern with the ongoing MCS
for at least the next few hours.

DISCUSSION...A mature cold-pool-driven MCS continues to propagate
southeastward across western into central KS, with several recent
measured severe gusts noted. Recent KICT inbound velocity data shows
that a pronounced rear-inflow jet persists with this MCS, as well as
a book-end/line-end mesovortex on its northern flank. Furthermore,
this MCS will continue to progress southeastward amid a highly
sheared and buoyant airmass, characterized by 50 kts of effective
bulk shear (oriented roughly normal to the MCS leading line) and
2000+ J/kg MLCAPE, driven by 8+ C/km mid-level lapse rates. Given
the highly organized storm structure and favorable ambient
supporting environment, severe gusts will likely continue with this
MCS for at least a few more hours.

Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
0759 PM CDT Sat Jun 20 2026

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.
