MD 1039 CONCERNING SEVERE THUNDERSTORM WATCH 290... FOR PORTIONS OF CENTRAL KS
Mesoscale Discussion 1039
NWS Storm Prediction Center Norman OK
0944 PM CDT Mon Jun 08 2026
Areas affected...portions of central KS
Concerning...Severe Thunderstorm Watch 290...
Valid 090244Z - 090345Z
The severe weather threat for Severe Thunderstorm Watch 290
continues.
SUMMARY...Significant severe gusts of 100+ mph have occurred and may
continue downstream of an intense bowing segment and merging
supercell over the next hour.
DISCUSSION...Recent radar and surface observations of the bowing
complex across Saline and Dickinson Counties in KS show significant
severe wind gust potential. The environment is extremely unstable
and supportive of gusts over 100 mph.
An internal surge within the bowing segment recently produced a
measured 113 mph gust at KSLN. Additional significant gusts of 100+
mph are possible where a supercell is interacting with the gust
front near the Saline/Dickinson county line. The significant wind
threat may continue over the next hour as the bowing complex surges
southeastward.

0855 PM CDT Mon Jun 08 2026
Areas affected...central and eastern Kansas
Concerning...Severe Thunderstorm Watch 290...
Valid 090155Z - 090400Z
The severe weather threat for Severe Thunderstorm Watch 290
continues.
SUMMARY...An evolving thunderstorm complex will move southeastward
with a risk for severe gusts this evening.
DISCUSSION...Ongoing convection over Tornado Watch 287 and Severe
Watch 290 has grown upscale into an organized and linear convective
complex this evening. Further upscale growth is likely as the
cluster interacts with a very unstable environment (MLCAPE 4000+
J/kg) and a 25-35 kt southerly low-level jet. The strong instability
and cold pool will likely support severe gusts through this evening.
A few significant gusts to 75+ mph are also possible.
Observed low-level shear is also fairly strong from the ICT VAD
(0-1km SRH of 100-200 m2/s2). This could support a couple of
tornadoes, both with the linear cluster, and with interacting cells
ahead of the outflow. With the complex expected to continue
east/southeast, the risk for severe wind gusts remains high across
WW290.

MD 1037 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR WESTERN/CENTRAL NEBRASKA INTO NORTHERN KANSAS
Mesoscale Discussion 1037
NWS Storm Prediction Center Norman OK
0758 PM CDT Mon Jun 08 2026
Areas affected...western/central Nebraska into northern Kansas
Concerning...Severe potential...Watch possible
Valid 090058Z - 090300Z
Probability of Watch Issuance...60 percent
SUMMARY...Damaging wind potential to evolve downstream through the
evening.
DISCUSSION...One or more clusters of thunderstorms will move
downstream into portions of western and central Nebraska into far
northern Kansas this evening. Surface objective analysis suggests
MLCIN is in place across portions of central Nebraska, with
temperatures cooling with the diurnal cycle. THe 00z sounding from
LBF further supports this notion with a warm nose around 850-700 mb.
With loss of heating, it is likely MLCIN will remain, which may
temper the downstream severe risk with northern extent.
A more well defined cluster coming out of eastern Colorado may
present the more likely severe potential into the evening.
Downstream across southern Nebraska into northern Kansas, MLCIN
weakens with a steep gradient of MLCAPE around 1000-4000 J/kg
extending into north-central Kansas. Additionally, strong deep layer
shear is in place which should foster organization of a damaging MCS
this evening.
A new Severe Thunderstorm watch may be possible to replace portions
of Tornado Watches 288 and 287 by 03z.

Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0805 PM CDT Mon Jun 08 2026
Valid 090100Z - 091200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE CENTRAL PLAINS...
...SUMMARY...
Severe thunderstorms with large to very large hail, damaging wind
gusts and a couple of tornadoes are likely this evening from parts
of northeastern Colorado into northwestern Kansas. Large to very
large hail, severe wind gusts from 60 to 90 mph, and a tornado
threat are likely this evening across parts of north-central and
eastern Kansas. An isolated severe threat may persist for a couple
more hours from the eastern Texas Panhandle into northwestern
Oklahoma.
...Northeast Colorado/Northwest Kansas...
A mid-level shortwave trough, evident on water vapor imagery, is
currently moving northeastward across northeast Colorado. At the
surface, a front is located across eastern Colorado with a moist
airmass extending from northeastern Colorado southeastward into
western Kansas. Surface dewpoints along this corridor range from the
upper 50s to the mid 60s F, which is contributing to moderate to
strong instability. Scattered severe thunderstorms are ongoing
across northeastern Colorado along the western edge of the stronger
instability, and further north into far southeast Wyoming and
western Nebraska. The storms are expected to organize into a line
and move east-southeastward into southwestern Nebraska and
northwestern Kansas this evening. Large to very large hail will be
possible with the more intense supercells over the next hour or two,
mainly along the southern end of the line where some cells are
likely to remain discrete. Hailstones up to 3 inches in diameter
will be possible. A couple tornadoes will also be possible with
supercells. As a transition to linear mode occurs, the wind-damage
threat will increase. Wind gusts above 75 mph will be possible near
the leading edge of any bowing segments.
...North-central and Eastern Kansas...
On water vapor imagery, a subtle shortwave trough appears to be
located from southern Nebraska southward into central Kansas. Ahead
of this feature, a pocket of strong instability is analyzed by the
RAP over south-central Kansas, where MLCAPE is estimated to be in
the 4000 to 5000 J/kg range. A line of severe storms is ongoing in
north-central Kansas, to the north-northwest of the instability
maximum. Multiple supercells with potential for large to very large
hail are ongoing within this line. Over the next couple of hours,
this line is expected to organize into a bowing segment, moving
east-southeastward across the remainder of north-central Kansas and
into eastern Kansas later this evening. The instability combined
with 30 to 40 knots of 0-6 km shear, and steep mid-level lapse rates
near 8 C/km will support a wind-damage threat. If a bowing line
segment can become intense later this evening, a potential will
exist for significant wind gusts above 80 mph. The wind-damage
threat will likely impact far eastern Kansas later this evening, and
western Missouri after midnight. A secondary line of thunderstorms
with severe wind gusts is expected to impact parts of north-central
Kansas after midnight.
...Eastern Texas Panhandle/Northwestern Oklahoma...
A very moist and unstable airmass is located across the southern
Plains. Surface dewpoints from the eastern Texas Panhandle into
northwestern Oklahoma are in the mid 60s to lower 70s F. This is
contributing to strong instability with the RAP showing MLCAPE in
the 3000 to 3500 J/kg range, with steep low-level lapse rates. The
thermodynamic environment should support an isolated threat for
severe wind gusts for a couple more hours this evening...see MCD
1036.
...Far Western Kentucky...
A bowing line segment is currently ongoing in far western Kentucky
along an axis of moderate instability, where the RAP has MLCAPE near
2000 J/kg. RAP forecast soundings to the south of Paducah have 0-3
km storm-relative helicity around 200 m2/s2 early this evening,
suggesting that an isolated tornado threat may persist for another
hour or two. A few strong wind gusts will also be possible.

SPC Day 3-8 Fire Weather Outlook
SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0455 PM CDT Mon Jun 08 2026
Valid 101200Z - 161200Z
...Synopsis...
A large scale upper trough will gradually shift eastward from the
Northern Rockies on Day 3/Wednesday into the Great Lakes by Day
5/Friday. A troughing pattern will likely remain entrenched across
Ontario Canada and northeastern U.S. with another possible short
wave pushing southeastward into the Northern Rockies early next
week. The departing trough and accompanying stronger mid-level flow
will subdue broader fire weather concerns across the West later this
week as the amplifying ridge promotes a warming and drying trend
across the region.
...Day 3-5/Wednesday-Friday...
...Eastern Great Basin, Colorado Plateau and central High Plains...
Stronger westerly surface winds in the wake of a cold front below a
pronounced 80-90 knot mid-level jet, will likely bring an enhanced
fire weather concern to portions of southeastern WY and western NE
Panhandle on Day 3/Wednesday. 70% critical probabilities have been
introduced where west winds of 25-30 mph and RH as low as 15% align
with pockets of dry fuels. Weaker but still impactful westerly flow
will bring a fire weather concern to much of the eastern Great
Basin, Colorado Plateau and Four corners regions where 40%
probabilities remain. The broader fire weather threat contracts
towards the Four Corners and adjacent southern CO Rockies by Days
4-5/Thursday-Friday as influence from the departing upper trough and
surface pressure features begins to wane.
...Sacramento Valley...
Dry, post-frontal northerly flow funneling into the Sacramento
Valley will likely promote an enhanced fire weather threat for this
region and adjacent valley foothills beginning Day 3/Wednesday,
lingering into Day 4/Thursday. North winds of 10 to locally 20 mph,
RH at or below 15% are expected to combine with receptive fuels to
support fire spread. 40% critical probabilities were added for Day
4/Thursday accounting for latest model guidance and duration of
event.
...Day 6/Saturday...
...Northern Arizona and Southern Utah...
A weak upper trough west of Baja Peninsula will aid in northward
transport of deeper Pacific moisture from Tropical Storm Boris
through the week, reaching the lower desert areas of the Southwest
as early as Day 5/Friday. Precipitable water values of one inch or
more should stay south of the Mogollon Rim region through the
weekend. A dry thunderstorm concern will likely exist on the fringes
of the deeper moisture across northern AZ into southern UT. A 10%
probability dry thunderstorm area was introduced, although some
modifications may be needed in subsequent outlooks as forecast
certainty increases.
