Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1128 AM CDT Thu May 31 2018

Valid 311630Z - 011200Z

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM PARTS OF
SOUTHERN MISSOURI INTO SOUTHERN INDIANA AND NORTHERN KENTUCKY...

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER THE NORTHERN
ROCKIES/HIGH PLAINS REGION AND SURROUNDING THE ENHANCED RISK...

...SUMMARY...
Clusters of severe thunderstorms, mainly capable of wind and hail,
are possible from the Missouri Ozarks to the lower Ohio Valley and
Tennessee Valleys, as well as the northern High Plains and northern
Rockies.

...Ozarks into OH Valley...
Multiple clusters of severe storms are expected to affect this
region today, with the first currently producing damaging winds over
southeast IL. These storms are expected to track eastward across
southern IN and northern KY through much of the day. Ref MCD #584
and WW #136 for more information.

In the wake of the initial band of storms, visible satellite imagery
shows rapid clearing across southern MO. This will result in strong
heating, steepening low-level lapse rates, and destabilization
across this region by early afternoon. 12z models are consistent in
re-development of intense storms over this area as a weak shortwave
trough moves into the region from KS. The initial storms will
potentially be supercellular with the risk of very large hail and a
tornado or two. Storms should slowly organize and grow upscale as
outflows merge, with an eventual bowing complex producing damaging
winds expected to move across the ENH area through the evening.

...Northern Great Basin into Northern Rockies...
An active thunderstorm day is expected today from northeast NV and
eastern ID into much of MT. A large upper trough is moving across
CA, with large scale lift and strong winds aloft spreading across
the risk area. Strong heating is occurring this morning, with
dewpoints in the 50s over most of this region. Present indications
are that scattered fast-moving cells will form over the higher
terrain throughout this region, and along a cold front moving into
NV/ID. Multiple clusters of strong/severe storms may persist
through the afternoon and evening. Large hail and damaging wind
gusts will be the main threats.

Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0234 AM CDT Thu May 31 2018

Valid 021200Z - 031200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER A PORTION OF
THE MIDDLE AND LOWER MISSISSIPPI AND TENNESSEE VALLEYS...

...SUMMARY...
Severe storms are expected across portions of the middle through
lower Mississippi and the Tennessee Valley Saturday.

...Middle to lower Mississippi Valley and TN Valley regions...

High-amplitude shortwave trough expected to be situated over the
central and northern Plains early Saturday will begin to track more
east southeast through the upper and middle MS valley after cresting
synoptic ridge. This feature will be accompanied by a cold front
that will surge southeast through the Plains and MS Valley and is
forecast to extend from the OH Valley into southwest TX by the end
of this period. Preceding the front a very moist warm sector with
mid to upper 60s F dewpoints will exist beneath eastward expansion
of an elevated mixed layer, contributing to strong instability
(2000-3000 J/kg MLCAPE) but with also a capping inversion. Northern
portion of the front will occlude over the upper MS Valley where
storms will likely be ongoing from MN into a portion of NE/IA and
northern MO. Evolution of morning storms is uncertain, but some
potential will exist for storms on the southern flank across
northern MO to strengthen as associated outflow boundary continues
southeast into the destabilizing warm sector, and new storms may
develop along southeast surging cold front. Wind profiles along
southern periphery of upper trough will be sufficient for organized
storm structures including supercells and bowing segments with
possible upscale growth. Activity should continue into the lower MS
and TN Valleys during the evening within the evolving northwest flow
regime. Damaging wind and large hail should be the main threats. An
upgrade to higher probabilities may be needed in later updates once
mesoscale details become more evident.

Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1145 AM CDT Fri Jun 01 2018

Valid 011630Z - 021200Z

...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS EASTERN
NEBRASKA...

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE NORTHERN AND CENTRAL PLAINS AND SOUTHEAST STATES...

...SUMMARY...
Large hail, damaging winds, and a few tornadoes are likely from the
northern and central Plains into the middle Missouri Valley this
afternoon into tonight. Severe winds and some hail are expected
across parts of the Southeast, with isolated strong to severe storms
also across the southern High Plains.

...Northern/central Plains...
Water vapor imagery late this morning features a notable late-spring
shortwave trough spreading northeastward from the northern Rockies
toward the northern High Plains, with appreciable height falls
expected as far east as the middle Missouri Valley and Upper Midwest
by tonight. A belt of strengthening (and backing) mid-level winds
will precede this trough, while surface cyclogenesis occurs across
the Dakotas today, and secondary cyclogenesis occurs across the
central Plains tonight.

It appears that an initial increase in severe thunderstorms will
occur relatively early this afternoon across northern Wyoming and
southeast Montana with a few supercells capable of large hail.
Another focus for potentially intense storm development will be in
and around west-central/south-central North Dakota near a surface
triple point. Persistent regenerative convection at midday poses
some uncertainty, but abating cloud cover should allow for rapid
destabilization by mid/late afternoon. Deep-layer/low-level shear
will be more than adequate for supercells capable of large hail and
a few tornadoes especially across west-central/south-central North
Dakota where low-level SRH is likely to be maximized.

Farther south, additional at least isolated to widely scattered late
afternoon/early evening development is expected southward across
South Dakota and into central Nebraska initially in vicinity of a
surface trough, with more extensive upscale-evolving development
likely this evening as an upstream cold front overtakes the surface
trough. A very unstable environment will exist along and
south/southwest of a warm front, with deep-layer/low-level shear
maximized near/just north of the warm front. Supercells capable of
very large hail and some tornado risk can be expected initially,
with the scenario likely to result in mature MCS development by late
evening. Aided by a strengthening (50+ kt) low-level jet, an MCS is
likely to spread southeastward with damaging wind potential across
the Missouri Valley this evening and possibly into the overnight.

...Southeast States...
Although the severe-weather potential may not be as widespread as
previously thought, multiple outflow/differential-heating related
boundaries will help focus an increase in coverage/intensity of
thunderstorms this afternoon within a moist and increasingly
unstable environment. Damaging winds will be the most common impact,
although some hail is possible as well.

...Southern High Plains...
Widely scattered thunderstorms are forecast to develop this
afternoon near the dryline, from northwestern OK and the eastern TX
Panhandle southwestward across the lower Caprock region to the lower
Pecos River area around FST. Isolated severe gusts and/or hail
appear possible for a few hours before nocturnal cooling stabilizes
the air mass in the evening and convective coverage/intensity
accordingly declines.

By mid-afternoon, intense insolation will contribute to surface
temps above 100 F and very deep/well-mixed boundary layers -- even
on the moist side of the dryline -- beneath midlevel lapse rates
exceeding 8 deg C/km. Even where moist-sector dew points mix down
into the 50s F, heating and weak mass convergence readily should
remove MLCINH and contribute to MLCAPE exceeding 2000 J/kg in much
of the outlook corridor. DCAPE of 1000-2000 J/kg should be common,
supporting maintenance of hail and acceleration of downdrafts to
surface. Vertical shear is forecast to be modest by most measures
under or near the upper ridge, as low-level flow is expected to
weaken with southward extent, yielding small boundary-layer
hodographs. As such, the primary convective mode should be
multicellular, though some supercell structures are possible over
the Panhandle/western OK area where mid/upper winds and cloud-layer
shear will be more favorable.

Sent home from work today, it was a slow day due to the forecast and I have a sinus infection. Happy to see today will be an active severe weather day. Already have GR2 pulled up and ready to go. Hope to see some nice supercells today.

Already have extreme CAPE pushing into the Plains threat areas. Western extent of the moderate risk is at ~4000 SBCAPE.

There has been research that shows a respectable amount of derechos are parts of derecho families (i.e., at least one derecho over a span of a few days). In other words, if there's one, there may be more.

Yesterday wasn't a derecho in the traditional definition, but I believe they're at least decreasing the amount of significant wind reports to be a part of that definition (was 3).

Mesoscale Discussion 0608
NWS Storm Prediction Center Norman OK
0213 PM CDT Fri Jun 01 2018

Areas affected...Much of North Dakota...western into central South
Dakota

Concerning...Severe potential...Watch likely

Valid 011913Z - 012115Z

Probability of Watch Issuance...80 percent

SUMMARY...Severe storms are expected to develop and become more
widespread with time. One or two WW issuances will likely be needed
later this afternoon.

DISCUSSION...A cumulus field is becoming increasingly agitated
across western North Dakota/South Dakota, and a few thunderstorms
have also initiated across northwestern North Dakota and vicinity.
Convective trends should continue to increase across the region in
response from an 1) approaching, mid-level shortwave trough over
Montana/Wyoming, 2) weak convective inhibition, and 3) moderate to
strongly unstable thermodynamic profiles (i.e., MUCAPE values
ranging from around 1500 J/kg in central North Dakota to 4000+ J/kg
in western South Dakota. Backed surface wind fields along and north
of an east-west-oriented warm front was also contributing to
enhanced low-level shear especially across North Dakota, and initial
surface-based development in this area will likely have some tornado
potential.

With time the magnitude of forcing and rapidly weakening inhibition
will result in widespread convective development, with mixed
linear/cellular modes and upscale growth possible with eastward
extent. All modes of severe are likely with this scenario,
including tornadoes (especially across North Dakota) and very large
(2"+ diameter) hail (areawide). Pending evolution of convective
trends, one or more WWs will likely be issued before 21Z.

Areas affected...Western and Central Nebraska

Concerning...Severe potential...Watch likely

Valid 011956Z - 012200Z

Probability of Watch Issuance...95 percent

SUMMARY...Severe potential is increasing. A WW will likely within
the next hour.

DISCUSSION...Convective initiation is underway across far northern
Nebraska, in an environment characterized by extreme instability
(3500+ J/kg). While the 19Z LBF sounding indicates a cap remains in
place, agitated cumulus north of LBF suggests convective inhibition
is rapidly decreasing across central to northern Nebraska. The
extreme instability combined with over 35 kts of effective bulk
shear and modest low-level shear (0-1km SRH greater than 100 m2/s2)
suggest organized severe is likely. Damaging wind gusts and large
hail (including very large hail exceeding 2+ inches) appear to be
the main threats, though a tornado or two may also be possible given
the high levels of buoyancy in place.

The shear is good in the 19z Bismark sounding... just needs a bit more moistening and/or warming



19z sounding near where the current tornado warnings are


Sounding just west of the moderate risk

They put PDS wording on this non-confirmed tornado. Dunno why, but I'll give them the benefit of the doubt that they have more info than I do.
