Day 1 Convective Outlook

1158 PM CST Wed Nov 19 2025

Valid 201200Z - 211200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE
SOUTHERN PLAINS...

...SUMMARY...
Isolated severe thunderstorms are possible later today into this
evening across the southern Plains. Isolated hail, localized strong
to severe gusts, and a tornado or two are all possible.

...Synopsis...
A mid/upper-level shortwave trough initially extending from the
Southwest into northern Mexico will eject northeastward across parts
of the southern Plains later today. In response to this shortwave, a
surface low will gradually deepen across the south-central Great
Plains and move eastward through the period. A surface boundary
draped across parts of OK/AR in the morning will lift slowly
northward in the advance of the surface low. Upstream, another
shortwave trough will drop southward along the Pacific coast and
evolve into a closed midlevel low across southern CA by the end of
the period.

...Southern Plains...
Scattered storms will be ongoing across parts of the southern Plains
later this morning, aided by a modest low-level jet and ascent
attendant to the approaching shortwave trough. Initially moderate
MUCAPE and effective shear of 40+ kt could support a few strong to
locally severe storms during the morning from parts of eastern NM
into west/central TX and OK, with a threat of isolated hail and
locally gusty winds.

Convection will persist through the day, resulting in generally
modest heating and weakening midlevel lapse rates with time. As a
result, while deep-layer shear will remain relatively strong across
the warm sector, potential for organized convection downstream or in
the wake of morning convection remains somewhat uncertain. Depending
on the extent of heating and destabilization, at least some
potential for isolated supercells and/or organized clusters could
evolve during the afternoon and evening, with a threat of marginally
severe hail and locally damaging wind. Some enlargement of low-level
hodographs with time could also support a brief tornado threat from
parts of central/eastern TX into eastern OK and western AR, if any
surface-based supercells can be sustained.

Farther west, some CAM guidance depicts development of a modestly
organized convective line across NM into west TX during the
afternoon/evening, in closer proximity to the ejecting shortwave
trough. This could pose a threat of strong gusts, but it remains
quite uncertain as to whether instability will be sufficient to
support a severe threat with this scenario.

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.

Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1224 AM CST Thu Nov 20 2025

Valid 211200Z - 221200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Scattered thunderstorms are expected from the Texas coast into the
Tennessee Valley and central/southern Appalachians on Friday. Severe
thunderstorms are not expected.

...Synopsis...

A mid/upper shortwave trough will migrate east from the central
Plains to the Ohio Valley on Friday. Meanwhile, an upper low will
develop southward across southern CA/northwest Mexico. Cold
temperatures beneath the upper low will support isolated lightning
flashes across far southern CA into the Lower CO Valley. Further
east, a broad area of warm advection will transport Gulf moisture
northward across the south-central states toward the TN Valley. As
the upper trough develops east, a weak surface low will move along a
warm front draped across the OH Valley, while a cold front shifts
east across the Ozarks into eastern TX.

Stronger deep-layer southwesterly flow will overspread the warm
sector, but is expected to weaken some with time while also becoming
increasingly displaced to the north of the warm sector (in tandem
with stronger large-scale ascent) into the afternoon/evening.
Isolated to scattered thunderstorms are expected to develop within a
modestly unstable airmass ahead of the cold front, but sub-optimal
thermodynamic profiles and weakening vertical shear will limit
severe potential.

Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0112 PM CST Wed Nov 19 2025

Valid 211200Z - 221200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Scattered thunderstorms are expected from the Texas coast into the
Tennessee Valley and central/southern Appalachians on Friday. Severe
thunderstorms are not expected.

...Synopsis...
A low-amplitude mid-level trough will overspread the TN Valley as an
upper-low becomes established over CA on Day 3/Friday. Cooler
temperatures aloft associated with the CA low will support a few
lightning flashes, mainly offshore. Across the TN Valley, the
passage of the low-amplitude mid-level trough will encourage the
eastward translation of a weak surface low along the OH River toward
the Appalachians through the Friday period. A broad fetch of
low-level moisture will advect northward toward the OH River has a
cold front slowly approaches from the Ozarks (draped southwestward
into eastern TX). The warm sector south of the warm front along the
OH River, and ahead of the cold front east of the Ozarks, should be
adequately buoyant to support isolated to scattered thunderstorm
development through the day Friday into Friday evening.

Nonetheless, the aforementioned mid-level trough should further
de-amplify through Friday, with forcing for ascent expected to
weaken as low-level flow heavily veers with time. Furthermore, the
mainly unidirectional vertical wind shear will become increasingly
displaced from the richer low-level moisture and associated
buoyancy, limiting severe potential across the OH Valley and points
south/west.
