...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM A PORTION
OF THE OHIO VALLEY INTO THE MIDDLE ATLANTIC REGION...

...SUMMARY...
A few strong to severe storms are possible today over a portion of
the Ohio Valley into the Mid-Atlantic.

...Synopsis...

Upper trough will continue to advance slowly northeast through the
Great Lakes and OH Valley this period. Attendant occluded low will
move from WI to southeast Ontario. An occluded front will stretch
from the surface low in WI eastward into MI, then trail southward as
a cold front through western OH, the TN Valley and into the western
Gulf by 12Z today. Warm front will extend from central VA
northwestward through western PA. The cold front will advance east
and off the Atlantic seaboard during the evening.

...Upper Ohio Valley and lower Great Lakes region...

Leading band of convection along warm conveyor belt will likely
continue weakening as it moves into a more stable atmosphere. In
wake of this activity, a narrow corridor of weak instability may
develop from eastern OH into western and central PA, within the
mid-upper dry slot region and just ahead of the cold front, where up
to 500 J/kg MLCAPE is possible. A few storms might initiate in this
strongly sheared, but weakly unstable environment by late morning or
towards noon. Low-topped supercells and bowing segments are possible
with threat for mainly locally strong wind gusts and perhaps a brief
tornado. If it becomes more apparent instability will be sufficient
for sustained robust updrafts, a slight risk may be warranted in
later updates.

...Mid Atlantic region...

Convection will likely weaken during the morning as it moves through
the central and southern Appalachians. Farther downstream diabatic
heating is expected in the pre-frontal warm sector and up to 1000
J/kg MLCAPE is possible during the afternoon. However, mid-level dry
slot, presence of an inversion around 700 mb along with tendency for
the low-level winds to veer to southwesterly ahead of the front
suggest thunderstorm initiation might be problematic. Nevertheless,
at least a few thunderstorms are possible in this environment with
mostly unidirectional flow suggesting a few updrafts could develop
mid-level rotation, posing a risk for mainly strong downdrafts and
possibly some hail.

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 SLIGHT RISK OF SEVERE THUNDERSTORMS FOR NORTHERN
LOUISIANA INTO WEST-CENTRAL MISSISSIPPI...

...SUMMARY...
Isolated to scattered severe thunderstorms are possible across parts
of the lower Mississippi Valley during the evening and overnight.

...Synopsis...
A mid-level disturbance will move from AZ/NM eastward during the
period and reach the OK/AR border by early Tuesday morning. A
frontal zone initially in the northern Gulf of Mexico will advance
northward through parts of TX during the day as a surface low
develops over west-central TX by early evening. An inverted surface
trough will extend northwest through the TX Panhandle into the
central High Plains during the day. After dark, a cold front will
sweep east across much of TX as the surface low develops eastward
into MS at daybreak Tuesday.

...Southern Great Plains into the lower MS Valley...
Strengthening southerly low-level flow and increasing moisture from
the northwest Gulf will spread north through TX during the day.
Considerable cloud cover will likely limit destabilization across
east TX within a moist/marginally unstable warm advection zone.
Farther west over the TX Panhandle, isolated storms are forecast by
late afternoon within a northwest-southeast corridor. Steepening
tropospheric lapse rates will support a few strong to severe
thunderstorms potentially capable of a hail/wind risk. This
diurnally driven activity will likely weaken by sunset. Farther
south over northwest and into central TX, uncertainty remains
whether a few storms can manage to form during the late afternoon.
Wind profiles would support updraft rotation but a paucity of storm
coverage implied by model convective schemes, casts doubt whether
more than a storm or two will develop.

During the evening into the overnight, increasing mid-level height
falls will overspread east TX into the lower MS Valley. Storm
coverage will likely increase concurrent with a strengthening warm
conveyor and mid-level DCVA. Forecast soundings show a relatively
deep/moist boundary layer with strong deep shear. The more vigorous
storms may organize into a few small clusters/bands with an
accompanying damaging wind hazard being the primary concern near and
south of the warm front. This activity will likely spread east
across the MS River late Monday night into early Tuesday morning.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR NORTHEAST
TEXAS...SOUTHERN ARKANSAS AND NORTHERN LOUISIANA...AND INTO
WEST-CENTRAL MISSISSIPPI...

...SUMMARY...
Isolated to scattered severe thunderstorms are possible across parts
of the southern Great Plains during the late afternoon and evening
Monday, with the risk shifting into the Arklatex and lower
Mississippi Valley during the evening and overnight.

...Synopsis...
A mid-level shortwave trough will move from the Desert Southwest and
into the southern High Plains by the late afternoon, before moving
into the lower MS Valley by daybreak Tuesday. A residual frontal
zone from the weekend draped along the Gulf Coast will advance
northward across parts of TX as a surface low develops in the
southern High Plains during the day. The surface low is forecast to
develop eastward from northwest TX and along the Red River before
reaching southern AR by early Tuesday morning. A dryline/Pacific
cold front will sweep east across TX primarily after dark.

...Southern Great Plains into the lower MS Valley...
As cyclogenesis occurs over the southern High Plains during the day,
strengthening low-level southeasterlies will advect moisture
north/northwestward into northwest TX/western OK. Although moisture
will likely remain relatively stunted (surface dewpoints in the 50s
deg F), cooling mid-level temperatures resulting in steepening
700-500mb lapse rates, and strong heating near/west of the arcing
frontal zone and dryline, will contribute to weak destabilization.
Veering/strengthening wind profiles with height will support updraft
rotation and a risk for large hail with the stronger updrafts.
Elevated, marginally severe storms are possible farther east to the
north of the warm front over OK and AR during the evening and
overnight hours, as large-scale ascent spreads east.

Farther south in TX, isolated to scattered thunderstorms are
possible mainly during the late afternoon/early evening. There is
still uncertainty regarding storm initiation (e.g., dryline, warm
conveyor farther east). A hail/wind risk would likely accompany the
stronger storms, but yet-to-be-resolved mesoscale details preclude
higher severe probabilities. Model run-to-run continuity lends
confidence in greater storm coverage after dark from parts of north
TX east into MS as a LLJ strengthens. Forecast soundings suggest
organized storm structures including bowing segments and supercells
are possible with the activity Monday night. Hail and wind appear
to be the primary risks but a tornado risk could develop as
low-level shear intensifies late.
