...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE CENTRAL HIGH PLAINS REGION...

...SUMMARY...
Scattered convection, with isolated strong to marginally severe
thunderstorms, will spread across portions of the central High
Plains region on Sunday.

...Central High Plains Region...

Dominant upper anticyclone is currently centered over the TX
Panhandle and this feature is expected to move little through the
day1 period. As a result, any weak disturbances will be directed
north across the Great Basin toward WY/MT where these features will
then turn southeast and advance toward the lower OH Valley. One such
feature is currently located over eastern NV/western UT. Substantial
convection developed ahead of this feature across the Great Basin
Saturday afternoon/evening. Scattered convection will likely evolve
downstream across WY/northern CO later today, especially as boundary
layer warming aids destabilization. Forecast soundings for
CPR/LAR/GXY all exhibit minimal inhibition by 21z and scattered
thunderstorms should readily develop in response to this approaching
short wave. Weak deep-layer flow/shear suggest updrafts will
struggle to organize; however, sufficiently steep lapse rates and
adequate instability favor gusty winds and perhaps marginally severe
hail with the strongest cores. Latest model guidance suggests a
notable increase to the LLJ across western KS into western NE during
the evening which should encourage eastward propagation after
sunset.

The "Convective Outlooks" issued by SPC can be thought of as a detailed discussion of the Severe Thunderstorm threat and it's associated risks nationwide. Risk levels range from Marginal to Slight, Enhanced, Moderate, and High and are issued based on the likelihood of 3 major severe weather threats; the risk of tornadoes, damaging winds, and hail. These discussions are often heavily laced meteorological terminology that may be difficult to understand without a background in the field. However understanding these discussions shouldn't be thought of as necessary. Instead, should DuPage county fall under one of these threat levels for severe weather, the response should be to have a heightened level of awareness about the deveoloping weather. Keep an eye on the "Watch County Notification" for any active severe weather watches issued for DuPage county; the "Hazardous Weather Outlook" and "Severe Weather Statement" can also be helpful in explaining the developing risk; additionally, watch for "Active Weather Warnings" and keep an eye on our "Regional Satellite and Radar" products which can be viewed with active watches/warnings or lightning activity.

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
GEORGIA INTO THE CAROLINAS AND SOUTHERN VIRGINIA...AND PORTIONS OF
THE CENTRAL PLAINS...

...SUMMARY...
Isolated strong to severe thunderstorms may occur Monday across
parts of Georgia into the Carolinas and southern Virginia, and for
portions of the central Plains. Occasional damaging winds and hail
should be the main threats.

...Georgia into the Carolinas and Southern Virginia...
An upper trough centered over much of the eastern CONUS and Canada
should move little on Monday. Around 30-40 kt of mid-level
northwesterly flow should be present on the southern periphery of
the upper trough, and to the east of upper ridging over the Plains.
A weak surface low initially over KY should develop towards the
Carolinas through the day, with a trailing cold front slowly moving
east-southeastward across the TN Valley into the central
Appalachians and Southeast through the period.

A seasonably moist low-level airmass should be in place ahead of the
cold front. Diurnal heating of this airmass should encourage the
development of around 1500-2500 J/kg of MLCAPE by Monday afternoon
from portions of the Deep South into the western/central Carolinas.
Current expectations are for thunderstorms to gradually increase in
coverage and intensity through the afternoon and early evening along
and ahead of the front. 25-40 kt of effective bulk shear is forecast
across these areas, decreasing with southwestward extent into GA.

Convection should organize into multiple small bowing clusters with
time, with a couple supercells also possible. With steepened
low-level lapse rates where robust diurnal heating occurs, isolated
strong to damaging winds should be the main threat as this activity
spreads east-southeastward through early Monday evening. Occasional
hail may also occur with any marginal supercells. With instability
forecast to decrease towards the coast, these thunderstorms should
gradually weaken with eastward/southward extent Monday evening.

...Central Plains...
An upper ridge should continue to dominate much of the western and
central CONUS on Monday. Most guidance shows a low-amplitude
mid-level perturbation rounding the apex of the ridge and spreading
east-southeastward across parts of the central Plains through the
period. Modestly enhanced mid-level west-northwesterly winds should
accompany this feature. A surface low should consolidate over KS and
vicinity through the day while deepening slightly, with a narrow
corridor of rich low-level moisture extending from parts of NE into
eastern KS and MO. A cold front is forecast to make some southward
progress across the central High Plains through Monday evening.

It appears that weak ascent associated with the low-amplitude
shortwave trough may be sufficient to aid robust thunderstorm
development across parts of NE by late Monday afternoon. This
activity should generally occur along/ahead of the cold front.
Various NAM forecast soundings across this region show a favorable
thermodynamic and kinematic environment for multicells and marginal
supercells. The main uncertainty continues to be overall
thunderstorm coverage in this narrow zone. Have included low severe
probabilities for both hail and wind, with the potential for a
supercell or small cluster to track generally southeastward across
NE towards the KS border through early Monday evening. Confidence in
convection persisting Monday night was not high enough to extend the
Marginal Risk farther south/east into north-central KS at this time.

Initially high-based convection should also develop over the higher
terrain in northern/central CO, before spreading eastward into the
central High Plains by late Monday afternoon. Mid-level winds should
remain fairly weak across this area, which is forecast to be on the
southern periphery of the shortwave trough. Still, any of this
activity that occurs along/near the southward-moving cold front may
be capable of producing strong to locally severe wind gusts, as
low-level lapse rates are forecast to steepen through the day due to
diurnal heating and the boundary layer becoming well mixed. The best
convective signal in guidance for a small cluster occurring is
across parts of northeastern into east-central CO. Accordingly, low
severe wind probabilities have been included to address this
potential.

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
NORTHEASTERN OKLAHOMA...SOUTHEASTERN KANSAS...SOUTHWESTERN
MISSOURI...AND NORTHWESTERN ARKANSAS...

...SUMMARY...
Isolated severe thunderstorms appear possible Tuesday across parts
of northeastern Oklahoma, southeastern Kansas, southwestern
Missouri, and northwestern Arkansas.

...Southern/Central Plains into the Ozarks...
Large-scale upper ridging is forecast to remain prominent over much
of the western/central CONUS on Tuesday, with an upper trough/low
moving little over the eastern states. In between these two
features, a low-amplitude shortwave trough should move southeastward
through the day from parts of the central Plains into the Ozarks.
Modestly enhanced mid-level northwesterly winds attendant to the
shortwave trough should overspread these regions by Tuesday
afternoon. At the surface, an area of low pressure should be in
place over OK. A cold front should move southward across the central
Plains through Tuesday evening, while a warm front sharpens east of
the low across the Ozarks. A dryline/surface trough should extend
southward from the low across the southern Plains.

A narrow corridor of moderate instability should develop from
southeastern KS/northeastern OK into the Ozarks Tuesday afternoon
along and south of the warm front, where most guidance suggests
upper 60s to low 70s surface dewpoints should be in place. Modest
convergence may be maximized to the northeast of the surface low by
peak afternoon heating in the vicinity of a triple point. It appears
that enough low-level convergence and modest large-scale ascent
associated with the shortwave trough may exist to support robust
surface-based thunderstorms by late Tuesday afternoon. If this
activity forms, it would pose an isolated severe threat given
moderate instability and adequate deep-layer shear forecast. A small
Marginal Risk has been included to account for this possibility,
with the southeastward extent of appreciable severe risk into AR
Tuesday evening/night remaining rather uncertain.
