SPC Convective Outlook Day 1

SPC AC 180459

Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1159 PM CDT Wed Sep 17 2025

Valid 181200Z - 191200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS CENTERED FROM
OKLAHOMA INTO MISSOURI...AND INCLUDING PORTIONS OF SURROUNDING
STATES...

...SUMMARY...
Strong to locally severe storms are possible from late afternoon
into tonight from parts of Oklahoma into Missouri and over small
parts of adjacent states.

...Discussion...
An upper trough will remain over much of the central and northern
Plains, with cool midlevel temperatures extending as far south as
northern TX. An upper disturbance will move across OK and KS during
the day, pivoting into IA/MO/AR during the evening. Cooling
aloft/height falls associated with this feature should aid daytime
destabilization.

At the surface, a weak boundary should extend from the TX Panhandle
into northern OK, and into the eastern KS/western MO vicinity.
Daytime heating will combine with the cool air aloft and a
marginally moist boundary layer to produce MLCAPE on the order of
1500 J/kg. Early day rain/storms may occur over KS beneath midlevel
cold pocket, and some of this activity could eventually produce
small hail.

By late afternoon and as the low-level lapse rate plume is
established, renewed development is expected from eastern KS into
OK, with activity pushing into western MO and northwest AR through
evening. Overall, deep layer shear will be marginal, however, strong
high-level flow may support a greater chance of hail from the TX
Panhandle into OK, while the coldest midlevel temperatures also
support hail from eastern KS into MO.

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
1223 AM CDT Thu Sep 18 2025

Valid 191200Z - 201200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe storms are not currently expected on Friday.

...Synopsis...

An upper shortwave trough will move across the northern/central
Plains to the Mid/Upper MS Valley on Friday. At the surface, a weak
low over southwest MN will lift north through the period, while a
broad area of weak low pressure overspreads the central High Plains.
Light southerly low-level flow will maintain mid 50s to mid 60s F
dewpoints from the south-central U.S. northward into the Upper MS
Valley. Pockets of weak instability are forecast, supporting diurnal
thunderstorm activity from the southern Plains into the Mid/Upper MS
Valley. Poor lapse rates and generally weak vertical shear will
preclude severe thunderstorm potential through evening.

As the upper shortwave trough ejects across NE toward the MO Valley
overnight, isolated elevated convection could develop over KS in a
warm advection regime. Cooling aloft will support steepening
midlevel lapse rates. Northwesterly flow aloft will also strengthen
on the back side of the upper trough. A couple of strong storms
could produce sub-severe hail.

Additional thunderstorms are possible across parts of the West as an
upper shortwave trough moves northward across CA/NV into OR, an
shortwave perturbations migrate through upper ridging over the Four
Corners.
