Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0256 PM CDT Sun Oct 19 2025

Valid 192000Z - 201200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS THROUGH TONIGHT
FROM THE APPALACHIANS INTO THE MID-ATLANTIC...

...SUMMARY...
Low-topped convection with isolated lightning flashes may produce
occasional strong-damaging gusts, and possibly a brief/weak tornado,
through the remainder of this afternoon into the Appalachians and
tonight into the Mid-Atlantic.

...20Z Update...
Given the increasing lack of large-scale support and the weakening
trend of convection near the west-central coast of Florida, severe
probabilities have been removed from the Florida Panhandle/Big Bend.

A shallow band of convection continues north and eastward from the
upper Ohio Valley into the central Appalachians. The strongest
mid-level ascent will continue into the Mid-Atlantic this evening.
Despite minimal buoyancy, strong low/mid-level winds will support
sporadic damaging wind gust potential.

..Wendt.. 10/19/2025

.PREV DISCUSSION... /ISSUED 1123 AM CDT Sun Oct 19 2025/

...Appalachians this afternoon into the Mid-Atlantic tonight...
A sharp midlevel trough and associated 100+ kt jet will progress
from TN/KY late this morning to the Mid-Atlantic region by early
Monday morning. An associated surface cyclone is in the process of
occluding just north of Lake Superior, while a trailing cold front
continues eastward across the upper OH Valley/Appalachians today and
reaches the Atlantic coast/southern New England overnight. A narrow
band of shallow convection/enhanced reflectivity coincides with the
front/wind shift from eastern KY into OH as of 16z. West of the
surface wind shift, low-topped convection with isolated lightning
flashes continues with the primary midlevel vorticity max/left-exit
region of the jet across central KY/middle TN.

Buoyancy is expected to remain weak (MUCAPE of 100-300 J/kg) and the
depth of the frontal convection will be marginal for charge
separation and lightning production. Still, there will be some
potential for downward momentum transfer of ~50 kt low-midlevel flow
and isolated wind damage with the consolidated convective band this
afternoon from eastern OH/KY and WV eastward into the Appalachians,
and overnight into the Mid-Atlantic.

...Northeast Gulf coast this afternoon...
The remnants of early morning convection persist near and south of
the FL Panhandle in association with a pre-frontal wind shift and a
weakening southern stream shortwave trough. Forcing for ascent is
expected to weaken through the afternoon and substantial inland
destabilization is unlikely given widespread clouds and weakening
southerly flow components with time. Thus, any remaining severe
threat will be confined to the coast and will likely end later this
afternoon.

...WA coast today...
A midlevel trough with associated cold air aloft and steep
low-midlevel lapse rates is spreading inland. A few low-topped
thunderstorms have been observed this morning along the WA coast,
and a few additional storms will be possible for the next 6 hours or
so. Vertical shear is sufficiently strong for some storm
organization, but the odds of sustained supercells appear too low to
warrant the introduction of severe probabilities.

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
1211 PM CDT Sun Oct 19 2025

Valid 201200Z - 211200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe storms are unlikely Monday.

...Synopsis...

An upper trough will lift northeast across New England on Monday. At
the same time, a surface low will develop east across Quebec with a
trailing surface front moving across New England. Showers and
thunderstorms will likely be ongoing Monday morning along the front
within a warm advection regime. Southeasterly low-level flow will
support a narrow warm sector across the region, though instability
will remain muted given poor lapse rates. Still, strong mid/upper
flow could foster gusty winds as the front moves across New England
through early afternoon, though severe potential will remain low.

Additional thunderstorms will be possible further south across FL
where the southern extent of the New England surface front will arc
southwestward across the FL Peninsula. A moist boundary layer and
modest instability may support isolated thunderstorms during peak
heating, but weak vertical shear and poor lapse rates will preclude
severe thunderstorm potential.

Further west, another upper trough will move across the Plains to
the MS Valley. In tandem with the upper system, a surface front will
sweep across the Plains into the Midwest. Given a prior cold front
passage, the airmass will remain dry and thunderstorm activity along
the front will be limited. Cold temperatures aloft may be sufficient
for a lightning flash or two across the Upper Midwest or Great Lakes
vicinity, but overall coverage is expected to be less than 10
percent.

Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0210 PM CDT Sun Oct 19 2025

Valid 211200Z - 221200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms are possible over the Great Lakes, South
Florida, and the northwest Gulf Coast regions Tuesday. Severe
thunderstorms are not expected.

...Synopsis...

A broad upper trough will envelop much of the eastern half of the
CONUS on Tuesday. A surface low will migrate across the Great Lakes,
with a trailing cold front developing southeast across TX and the
much of the Southeast and Eastern Seaboard. Rich boundary layer
moisture across coastal TX into LA will be in place ahead of the
front, aiding in weak to moderate destabilization through peak
heating. Stronger large-scale ascent will be focused well to the
northeast, but ascent along the front may support isolated
thunderstorms. Vertical shear will generally be weak, but a couple
of stronger storms could produce gusty winds. More robust updrafts
will likely be limited by poor midlevel lapse rates/warm midlevel
temps.

Additional isolated thunderstorms will be possible across parts of
the Great Lakes and upper Ohio Valley beneath the cold core of the
upper low/trough, and across south FL within a moist and unstable
environment. Severe storms are not expected.
