230 PM MDT Mon Jun 8 2026
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
Northeast Colorado
Far Northwest Kansas
Far Southwest Nebraska
* Effective this Monday afternoon and evening from 230 PM until
900 PM MDT.
* Primary threats include...
A couple tornadoes possible
Scattered large hail and isolated very large hail events to 4
inches in diameter likely
Scattered damaging winds and isolated significant gusts to 75
mph possible
SUMMARY...Isolated to scattered severe thunderstorms are forecast to
develop this afternoon and evening. The stronger storms will likely
become supercellular and pose a risk for a couple of tornadoes,
large to giant hail (1 to 4 inches in diameter), and severe gusts.
Some clustering of storms is possible later this evening with the
severe wind threat becoming more prevalent, but a lingering risk for
large hail and a tornado may continue with any surface-based
supercell.
The tornado watch area is approximately along and 60 statute miles
north and south of a line from 10 miles northwest of Denver CO to 25
miles north northeast of Goodland KS. For a complete depiction of
the watch see the associated watch outline update (WOUS64 KWNS
WOU8).
PRECAUTIONARY/PREPAREDNESS ACTIONS...

1000 PM CDT.
* Primary threats include...
A couple tornadoes possible
Widespread damaging winds and isolated significant gusts to 90
mph likely
Scattered large hail and isolated very large hail events to 4
inches in diameter likely
SUMMARY...Isolated to scattered supercells are forecast to develop
and intensify this afternoon into the early evening. Large to giant
hail will be possible with the supercells. A tornado risk with the
possibility for a couple of tornadoes will seemingly develop later
this afternoon into the early evening coincident with perhaps some
enhancement of low-level shear. Upscale growth into a severe linear
cluster is forecast to eventually evolve this evening with severe
gusts becoming more prevalent. Significant severe gusts ranging
from 75-90 mph are possible this evening as this storm evolution
occurs.
The tornado watch area is approximately along and 60 statute miles
north and south of a line from 25 miles south of Mccook NE to 55
miles east northeast of Russell KS. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU7).

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.

Mesoscale Discussion 1036
NWS Storm Prediction Center Norman OK
0641 PM CDT Mon Jun 08 2026
Areas affected...the eastern Texas Panhandle amd far northwestern
Oklahoma
Concerning...Severe potential...Watch unlikely
Valid 082341Z - 090145Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated severe storms will likely pose a threat for hail,
damaging gusts and a brief tornado this evening.
DISCUSSION...As of 2330 UTC, regional radar analysis showed two
stronger thunderstorms have matured along the dryline across the
eastern TX Panhandle. While vertical shear is rather modest, very
hot surface temperatures over 100 F and 60s F surface dewpoints are
supporting moderate instability with these supercells. Isolated
large hail is possible for the next couple of hours given the steep
lapse rates and buoyancy, along with the potential for damaging
winds with T/TD spreads of 40 degrees F. Recent reports of a
landspout also suggests a tornado is possible, especially in
Lipscomb County, TX where back building along the dryline/boundary
with enhanced vertical vorticity has been noted. Weak steering flow
and modest storm motions should keep the severe threat fairly
isolated. Inhibition is also forecast to increase rapidly with the
loss of diurnal heating this evening. This suggests a WW is not
needed, though trends will continue to be monitored.

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
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.
