...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF
FAR EASTERN TEXAS INTO LOUISIANA...

...SUMMARY...
Isolated large hail may occur with thunderstorms that develop across
parts of far eastern Texas into Louisiana tonight into early Friday
morning.

...Synopsis...
A compact mid-level shortwave trough will move across the Northeast
and eject into the Atlantic while modest surface lee troughing will
prevail along the East Coast through the day into early Friday
morning. Adequate moisture and lift associated with this lee
troughing will promote at least isolated thunderstorm development.
Meanwhile, a second trough aloft is poised to traverse the
Inter-mountain West while diverging from the broader upper cyclonic
flow regime and evolving into a 500 mb cutoff-low. At the surface, a
cold front will move across the Plains states, preceded by a region
of weak low pressure and associated low-level WAA across the
mid-South. Colder mid-level temperatures associated with the
approaching upper trough/cyclonic flow regime will contribute to
enough buoyancy to support a very isolated severe threat early
Friday morning.

...Portions of the mid Atlantic into the Carolinas...
As the aforementioned trough moves toward the Atlantic, a gradual
veering and weakening of the tropospheric wind profiles is likely.
Marginal instability will be in place to support isolated to
potentially scattered thunderstorm development, with strong enough
diurnal heating likely to promote some boundary-layer mixing.
However, the lack of both stronger buoyancy and flow aloft to be
transported to the surface suggests that severe gusts would be too
sparse for Marginal highlights at this time. Nonetheless, a strong
to marginally severe gust or two cannot be completely ruled out.

...Far eastern Texas into Louisiana...
Within the roughly 06-12Z time frame, a plume of steeper mid-level
lapse rates (up to 8 C/km based on 00Z NAM, GFS, and 03Z RAP
forecast soundings) is expected to overspread a modest
moist/warm-air advection regime, promoting over 1000 J/kg MUCAPE in
spots. While much of this instability is expected to be elevated,
cellular convection may ingest air-parcels down to 850 mb, within a
layer of modestly veering low-level winds, with around 150 m2/s2
effective SRH available to any storms that form. As such, storms may
become organized and long-lived enough to support isolated large
hail, with a Marginal risk for severe storms maintained over the
area.

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 ACROSS PARTS OF
CENTRAL/EAST TEXAS...LOUISIANA...AND SOUTHWESTERN MISSISSIPPI...

...SUMMARY...
Isolated strong to severe thunderstorms may occur Friday across
parts of central/east Texas, Louisiana, and southwestern
Mississippi. Large hail and strong to damaging winds should be the
main threats.

...Texas into the Lower Mississippi Valley...
Mainly elevated thunderstorms will probably be ongoing to the north
of a warm front at the beginning of the period across parts of east
TX and LA. This activity will be supported by modest low-level warm
advection, which is forecast to weaken through Friday morning.
Still, given the forecast combination of MUCAPE around 500-1250 J/kg
and 35-45 kt of deep-layer shear, this convection may continue to
pose an isolated large hail threat across parts of LA and perhaps
southwestern MS through the morning hours before diminishing.

As a closed upper low slowly pivots across the Southwest and towards
the southern High Plains through the period, a belt of enhanced
west-southwesterly mid-level winds will remain over much of
central/east TX into parts of the lower MS Valley. A generally
southwest-northeast oriented surface boundary should be located over
these areas, with rich low-level moisture characterized by upper 60s
to perhaps low 70s surface dewpoints to its south. It appears that
this boundary will serve a focus for potentially robust convection
through the day, possibly beginning by early afternoon across
central TX as an upper jet overspreads this region. Up to 1000-1500
J/kg of MLCAPE may develop along/south the front. Coupled with
strong deep-layer shear, this should support some organized
convection. Isolated large hail and strong to locally damaging wind
gusts appear to be the main threats as storms move slowly
east-southeastward into coastal TX/LA in tandem with the surface
front through Friday evening.
