Day 1 Convective Outlook

Valid 230100Z - 231200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER A PORTION OF
SOUTHERN ARIZONA...

...SUMMARY...
Scattered thunderstorms capable of damaging wind gusts will persist
this evening mainly over southern Arizona.

...Southern Arizona...

Thunderstorms that initiated over the mountains of southeast AZ are
moving westward, and other storms that developed over the Mogollon
Rim are moving southwest. These storms with consolidating outflows
will continue to produce occasional downburst winds this evening as
they move through southern AZ where deeply mixed boundary layers
with 40 F surface temperature/dewpoint spreads exist.

...Middle Atlantic region...

Multicell storms continue developing in warm sector from the
Carolinas into the Middle Atlantic region where MLCAPE ranges from
1500-2000 J/kg, and a belt of 30-35 kt winds exist in the 900-700 mb
layer. These storms will remain capable of producing a few strong to
damaging wind gusts through mid-evening, before a stabilizing
boundary layer contributes to a gradual weakening trend.

...Southeast Wyoming through central Colorado...

Storms moving off the higher terrain will remain capable of
downburst winds through mid-evening, followed by a gradual weakening
trend as the atmosphere stabilizes.

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 MARGINAL RISK OF SEVERE THUNDERSTORMS FROM SOUTH
CAROLINA ACROSS CENTRAL AND EASTERN NORTH CAROLINA AND EXTREME
SOUTHEAST VIRGINIA...

...SUMMARY...
Numerous thunderstorms with a few damaging wind gusts are possible
Tuesday mainly across the central and eastern Carolinas.

...Synopsis...
An upper high will be centered over the Four Corners states, with a
ridge extending north across WY and MT. Northern portions of this
ridge will break down Tuesday night as a shortwave trough moves
across ID and MT, and this feature will also support thunderstorms
through evening.

To the east, a deep upper trough will approach the Appalachians with
cooling aloft and substantial southerly winds. A cold front will
slowly move across eastern VA and the Carolinas, where a moist and
unstable air mass will support numerous daytime thunderstorms, some
producing strong wind gusts.

...Eastern NC/SC and extreme southeast VA...
A very moist air mass with mid 70s F dewpoints will exist ahead of
the cold front, and heating will lead to MUCAPE in excess of 2000
J/kg prior to frontal passage. Substantial lift along the front will
lead to early afternoon development, with numerous storms expected
from southeast VA across the Carolinas. Storms may be cellular at
first, but deep-layer shear and mean winds will be oriented parallel
to the front. The result should be merging outflows, with linear
structures advancing east throughout the day. Shear will be weak,
but numerous storms with substantial outflow will create
opportunities for marginally severe but locally damaging wind gusts.

...Southwest into central MT...
Batches of storms are likely to develop near the ID/MT border during
the afternoon with the upper disturbance which will eventually
flatten the ridge. A steep lapse rate environment will exist, with
generally weak winds below 700 mb. This may support small hail and
gusty winds, but severe weather is generally not anticipated as
storms continue into central MT through evening.

...MAXIMUM RISK BY HAZARD...
Tornado: <2% - None
Wind: 5% - Marginal
Hail: <5% - None

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF
THE NORTHERN PLAINS...

...SUMMARY...
Isolated severe storms will be possible Wednesday across portions of
the northern Plains.

...Synopsis...
The eastern U.S. upper trough will continue east towards the
mid-Atlantic/northeast coast on Wednesday as upper-level high
pressure remains entrenched over the southwest states. A belt of
stronger mid-level flow will extend from the Pacific Northwest into
the northern Plains, and a pronounced shortwave trough will move
east across the Canadian Rockies along the international border. A
surface frontal boundary extending from northern FL west through
south TX will move little, while a cold front, initially across the
northern Rockies, moves east into the northern Plains Wednesday
night.

...Northern Plains...
The large-scale ridge is forecast to flatten somewhat with the
approach of the Pacific Northwest upper trough and monsoon impulses
rotating around the upper-level anticyclone. Weak/pockets of
moderate instability should develop by afternoon along a pre-frontal
trough as diurnal heating of upper 50s/lower 60s dew points takes
place. Thunderstorms may develop along the pre-frontal trough and
the approaching cold front, though an expanding EML and increasing
CINH may limit overall coverage. Adequate shear (35-40 kts) will be
in place for updraft organization and support at least some risk for
severe storms.
