From one thread straight to another.

SPC has a day 3 and 4 slight risk out.

The "hole" of EHI south of the EHI maximum is some sort of massive storm or MCS.




Extreme SE NE




Along KY/IL border

SPC seems to like a possible severe threat Saturday and especially Sunday east of the Mississippi.

Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0355 AM CDT Wed May 16 2018

Valid 191200Z - 241200Z

...DISCUSSION...
Models indicate that there may be some adjustments to the mid/upper
flow during this period. While it appears that large-scale blocking
may persist within the mid-latitude westerlies, guidance suggests
that it will shift inland of the Pacific coast, into areas near/east
of the Canadian/U.S. Rockies by the middle of next week, as the
leading edge of a strong zonal Pacific jet approaches the Pacific
Northwest coast. As ridging becomes more prominent over interior
North America, western Atlantic subtropical ridging into the
Northeast is forecast to become suppressed by broad large-scale
troughing within the mid-latitude westerlies. Upstream, another
southern branch closed low may develop and migrate inland of the
California coast early next week, before turning northeastward
toward the northern Rockies. It appears that this will also
maintain the suppression of subtropical ridging centered near/south
of Baja into the Mexican Plateau.

It might not be out of the question that the remnants of the
preceding closed low advancing into the central Plains by this
coming Saturday, and upper portions of the middle Mississippi Valley
into the vicinity of the southern Great Lakes/Ohio Valley region
Sunday, could be accompanied by some continuing risk for organized
severe storm development. This potential could be a little higher
Sunday than Saturday, when some possible phasing of the wave with a
northern branch impulse could result in strengthening wind fields,
in the presence of better low-level moisture near/east of the
Mississippi Valley. At the present time, due to substantial
lingering uncertainties, severe probabilities are being maintained
at less than 15 percent, and severe weather potential through the
remainder of the period still appears relatively low.

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE CENTRAL PLAINS AND LOWER MO VALLEY...

..SUMMARY

SEVERE THUNDERSTORMS WILL DEVELOP ACROSS THE CENTRAL PLAINS INTO THE
LOWER MISSOURI VALLEY SATURDAY. VERY LARGE HAIL AND DAMAGING WINDS
ARE THE PRIMARY THREATS.

..CENTRAL PLAINS/LOWER MO VALLEY

UPPER RIDGE IS EXPECTED TO SHIFT INTO THE MS VALLEY SATURDAY WHICH
WILL ALLOW A PLUME OF HIGHER PW AIR MASS TO SPREAD NORTH ACROSS THE
SOUTHERN/CENTRAL PLAINS INTO THE LOWER MO VALLEY. BOTH THE NAM AND
GFS SUGGEST A CORRIDOR OF STRONGER 500MB FLOW WILL TRANSLATE ACROSS

ALONG THE BOUNDARY ACROSS KS BY 21-22Z AND ROBUST
THUNDERSTORMS/SUPERCELLS SHOULD DEVELOP WITHIN A MODESTLY SHEARED
ENVIRONMENT AHEAD OF A PRONOUNCED COLD FRONT. THIS BOUNDARY WILL
SURGE SOUTH ACROSS THE HIGH PLAINS DURING THE LATTER HALF OF THE

SHORT-RANGE MODEL GUIDANCE SUGGEST A WEAK SURFACE LOW/WAVE WILL
EVOLVE ALONG THE FRONT ACROSS NORTHEAST KS OR PERHAPS SOUTHEAST NE.
LOW-LEVEL HELICITY WILL BE MAXIMIZED EAST OF THIS FEATURE INTO
NORTHERN MO, ALONG/NORTH OF A WARM FRONT THAT SHOULD ORIENT ITSELF
NEAR THE IA/MO BORDER. FORECAST SOUNDINGS ACROSS THE ENH RISK REGION
EXHIBIT SUPERCELL CHARACTERISTICS WITH ADEQUATE LOW-LEVEL SHEAR FOR
POTENTIAL TORNADIC DEVELOPMENT. IF DISCRETE STRUCTURES EVOLVE ACROSS
THIS REGION THERE APPEARS TO BE A RISK FOR VERY LARGE HAIL ALONG
WITH ISOLATED TORNADOES.

Day 3 Convective Outlook

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE MIDWEST/OH VALLEY...

...SUMMARY...
Strong storms may develop across portions of the Midwest and Ohio
Valley region Sunday.

...Midwest/OH Valley...

Central Plains short-wave trough is expected to induce a
considerable amount of convection across portions of the central
Plains/Lower MO Valley late Saturday. Remnants of this activity
should propagate into IA/northern MO by the start of the day3
period. While it's not entirely clear how much influence this
activity will have on the boundary layer, in all likelihood one or
more surface boundaries should serve as the focus for renewed
development by early afternoon. Latest thinking is multiple
clusters/MCS should be ongoing at the start of the period along nose
of a pronounced LLJ. Downstream boundary-layer heating will
contribute to destabilization that is expected to aid robust
thunderstorm development during the afternoon. While mid-level
heights may be somewhat ridgy, aforementioned convective influences
should encourage potentially strong thunderstorm development.
Hail/wind are the primary threats with convection that spreads
toward the OH Valley.

12z NAM and 12z 3K NAM seem worlds apart as far as Sunday goes. NAM has an MCS develop Saturday evening in the plains which dies out overnight and a new one develops on Sunday over N IL and moves east across N IN/N OH. 3K NAM has the same MCS Saturday night in the plains but it maintains itself crossing N IL and diving southeast to SW/S IN and then new storms fire across IL/IN/OH by the end of the run.

1128 AM CDT Fri May 18 2018

Valid 181630Z - 191200Z

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
THE CENTRAL PLAINS....

...SUMMARY...
Severe thunderstorms are possible near the Front Range of the
Rockies eastward into parts of the central and southern Plains late
this afternoon and tonight.

...Central and Southern Plains...
Nocturnal and morning convection now located over eastern Nebraska
and north central Kansas has generated an east-west low-level
boundary that extends from central Kansas into southeast Colorado.
Areas of widespread stable low clouds, especially over eastern
Colorado but also evident over northwest and north central Kansas,
will inhibit diabatic heating into at least early afternoon, and may
promote maintenance of a differential heating discontinuity that
will help focus later thunderstorm development.

The large scale pattern will continue to be characterized by modest
southwest flow aloft advancing eastward over the central and
southern Plains as weak perturbations embedded into the flow move
toward the High Plains. A surface low over southeast Colorado may
drift southward as strong heating occurs this afternoon, with the
aforementioned boundary serving as a focus for thunderstorm
development later this afternoon and evening. North of the
boundary, an easterly component to the low-level flow will provide
moist upslope winds, and dependent on the degree of cloud
dissipation and development of pockets of stronger heating, may
support additional storm development by mid-to-late afternoon.

Sufficient low-level moisture is in place over the central and
southern High Plains with surface dew points in the 50s and lower
60s. 12Z regional soundings continue to exhibit steep mid-level
lapse rates, and strong diabatic heating south of the central plains
boundary will contribute to moderate instability with MLCAPE of
1500-2500 J/kg. Although mid-level winds will be in the 25-35 kt
range, veering wind profiles will result in 35-45 kt bulk shear
which will enhance storm organization and intensity. In addition,
low-level shear will be stronger along and north of the boundary
where backed near-surface winds will be present.

Storms are expected to develop initially over parts of southeast and
north-central/northeast Colorado as the cap weakens this afternoon.
There is potential for a few discrete supercells to form in the
earlier stages of the convective cycle. Steep lapse rates will
enhance hail growth with these storms with potential for significant
hail to occur with stronger cells as they spread eastward with time
into western Kansas. The presence of a well-mixed deeper PBL will
also be supportive for strong wind gusts to occur.

Other severe storms are expected to develop near the dry line
extending southward into west Texas, with primary threats for large
hail and damaging winds. The overall thermodynamic environment will
be supportive of cold pool development and potential for storms to
grow upscale into one or more bowing line segments this evening.
This scenario is indicated by most morning CAM guidance and suggests
a transition to primarily a wind damage threat. A strengthening
southerly low-level jet is forecast to develop by this evening from
Texas across Oklahoma into southern Kansas, and the associated
convergence and warm advection near the terminus of the LLJ is
likely to maintain strong-to-severe convection spreading eastward
across Kansas into the overnight hours.

...Tennessee/Lower Ohio Valley and the Southeast...
Widespread convection is anticipated this afternoon as the moist air
mass over the region destabilizes amidst diurnal heating. Weak
vertical shear across the area suggests that the only severe
potential would come from water-loaded downbursts which result from
updraft strengthening due to cell mergers, but this is expected to
occur only on a very isolated/episodic basis.

Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1229 PM CDT Sat May 19 2018

Valid 201200Z - 211200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
THE MID-MISSISSIPPI AND LOWER OHIO VALLEYS...

...SUMMARY...
Strong to severe storms may develop across portions of the Midwest
and Ohio Valley region Sunday. Additional strong storms are possible
across portions of central Texas.

...Midwest/Ohio Valley Vicinity...

A somewhat complex forecast scenario is expected for Sunday, mainly
due to possible impacts from overnight convection in the Day 1
period and any ongoing storms Sunday morning. That being said, ample
opportunity for strong to severe storms will exist along a myriad of
surface boundaries. A cold front will be positioned along the MO/KS
border early in the afternoon with a weak surface low over northwest
MO. The front will then extend west to east across northern MO into
central IL/IN/OH. Strong heating to the south of the boundary, with
dewpoints in the mid to upper 60s, will result in strong
destabilization across portions of the Mid-MS and lower OH Valleys.
Midlevel lapse rates, while not impressive, will be adequate when
coupled with strong instability for maintaining stronger updrafts.
0-6km shear will be generally weak across the region in the absence
of stronger deep layer forcing for ascent. However, portions of the
region will be on the southern fringes of narrow corridor of
stronger bulk shear located over the Great Lakes and values ranging
from around 25-35 kt appear reasonable at this time. All of this
together should support storms capable of severe hail. Furthermore,
steep low level lapse rates and weak low level flow likely will
favor outflow dominant convection. As such, damaging winds will be
possible with some potential for upscale growth into one or more
bowing segments should stronger cold pools become established.

...Portions of Central Texas...

Severe potential across central TX also is somewhat uncertain due to
expected ongoing convection moving south/southeast toward the region
at the beginning of the period. The timing of this convection and
position of any related outflow boundary will impact where strong to
possibly severe storms may develop during the afternoon. Warm, moist
advection ahead of the boundary should result in scattered storm
development. Deep layer shear will remain weak, but modestly steep
midlevel lapse rates and moderate instability will be adequate for
at least brief intense updrafts capable of hail. Some stronger wind
gusts also will be possible as storms struggle to maintain
intensity/organization.

...MAXIMUM RISK BY HAZARD...
Tornado: 2% - Marginal
Wind: 15% - Slight
Hail: 15% - Slight
