Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0750 PM CDT Mon Sep 15 2025

Valid 160100Z - 161200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN WESTERN
SD/NORTHWEST NE PANHANDLE VICINITY AND FAR NORTHEAST NC...

...SUMMARY...
Isolated severe gusts remain possible this evening in the western
South Dakota and northwest Nebraska Panhandle vicinity. A brief
tornado and a severe gust are possible over far northeast North
Carolina in the early morning.

...SD/NE vicinity...
Scattered high-based convection along the WY/NE/SD border area
should continue to pose a near-term threat for sporadic strong to
severe gusts as it progresses east-northeast. Nocturnal
boundary-layer cooling should yield a rapid weakening in the next
couple hours within the mostly meager buoyant airmass. However, a
lobe of upper 50s to lower 60s surface dew points across
northwest/north-central SD may sustain a marginal severe wind threat
in this region through late evening.

...Northeast NC...
A weak offshore cyclone is still expected to approach the Outer
Banks to Albemarle Sound region by 12Z. Guidance does differ on
whether this will actually reach land or remain entirely off the
coast. It will depend on the degree of overnight convective
development around the cyclone, which most recently has been
wobbling to the east. Backing of current northerly surface winds to
the northeast will be required to advect around 70 F dew points onto
land, necessary for weak surface-based instability. This may occur
during the 09-12Z period, coincident with some enlargement to the
low-level hodograph. Should this occur, the setup might support a
brief tornado and/or a localized severe gust.

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

Valid 161200Z - 171200Z

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

...SUMMARY...
Isolated strong to severe thunderstorms are possible on Tuesday
across portions of the central Plains.

...Synopsis...
A positively tilted trough will move through the northern Great
Basin and eventually reach the High Plains by early Wednesday
morning. A weak surface trough/cold front will be positioned from
northern Minnesota southwestward into the central High Plains.
Another weak surface trough will extend farther south into the
southern High Plains. Off the Mid-Atlantic Coast, a weak surface low
will slowly shift north and weaken with time.

...Central Plains...
With the mid-level ascent from the approaching trough not arriving
until late afternoon/evening, it is not clear how much storm
development will occur prior to 00Z. Recent CAM guidance does
suggest that convergence along the surface trough/front may be
sufficient for late afternoon storms. The strongest shear will
likely remain behind the boundary. Upper 50s to mid 60s F dewpoints
will promote around 2000-3000 J/kg MLCAPE. Storms that do develop
will not likely remain discrete for very long given boundary
parallel shear. Isolated severe gusts and large hail will be the
main hazards. Storms should generally weaken during the evening and
beyond given a weak low-level jet response.

...Southern Plains...
While greater surface heating is expected to occur in this region,
limited low-level moisture will keep overall buoyancy modest. Shear
will also be rather modest during the afternoon. A cluster or two of
storms could develop in the High Plains and move eastward, possibly
producing locally gusty winds.

...Upper Mississippi Valley...
There is a weak signal within guidance for evening/overnight storm
development along the cold front. Convergence along the boundary
will only marginally increase after dark. Forcing for ascent will
also be weak and late-arriving. Steep lapse rates could promote a
stronger storm or two with an attendant hail risk. However, with
stronger shear behind the boundary and highly uncertain initiation,
probabilities do not appear warranted.

...North Carolina/Virginia Tidewater...
A weak offshore low will mostly remain offshore. The low will be
gradually weakening, particularly by the afternoon. Low-level flow
enhancement around the low may promote some increased risk for gusty
winds with convection, but limited onshore progression of greater
buoyancy along with rain/clouds will likely prohibit any greater
threat for damaging gusts.

Day 3 Convective Outlook

Valid 171200Z - 181200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorm potential is low on Wednesday.

...Synopsis...
An upper trough over the central/northern High Plains will make
limited progress eastward into the Plains on Wednesday. This feature
is expected to broaden and become more disorganized with time. A
surface trough/cold front from the central Plains into the southern
High Plains will similarly be mostly stationary until later in the
period. Mid-level flow in the Plains will generally remain weak with
only a modest increase behind the cold front closer to the upper
trough.

Morning clouds and precipitation are expected to be ongoing in the
central Plains and parts of the southern High Plains. Upper 50s to
mid 60s F dewpoints will be ahead of the boundary. This will lead to
weak to moderate buoyancy. Thunderstorms are likely in the Front
Range where low-end moisture and upslope flow overlap. This activity
may not be very intense given the buoyancy and uncertain low-level
thermodynamics. Thunderstorms in Kansas/Oklahoma will have greater
buoyancy, but shear will be more limited. Depending on the position
of the front and destabilization, isolated to widely scattered
thunderstorms could develop in the Raton Mesa vicinity. Marginal
northwesterly deep-layer shear could promote a couple of stronger
storms given steep lapse rates. However, confidence in a more
organized severe threat in the Plains remains low at this time.
