...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF
EAST/SOUTHEAST TEXAS INTO LOUISIANA...

...SUMMARY...
Isolated severe thunderstorms are possible across portions of east
and southeast Texas into western Louisiana today and tonight.

...Synopsis...
A broad upper trough and increasingly strong westerly flow over the
central US are forecast to quickly intensify today, moving into the
Ohio Valley by tonight. Accompanying the strengthening trough, a
surface low over OK will deepen and shift toward the mid MS valley.
Trailing the low, a strong cold front will sweep southeastward with
increasing moisture ahead of it over the far southern Plains. Ahead
of the front, isolated strong to severe storms are possible over
parts of East TX and western LA this afternoon into early Sunday
morning.

...Eastern Texas into western LA...
South of the surface low across parts of central and southeast TX,
low-level warm air advection is expected much of the day associated
with a weakening 850 mb low-level jet. Persistent southerly flow
will help transport low to mid 60s F dewpoints northward across the
TX coastal plain into portions of central TX and far western LA.
Filtered diurnal heating should allow for some warming of the
relatively cool boundary layer. This warming, along with the
increase in low-level moisture, should support at least weak
destabilization by peak heating as cold mid-level temperatures from
the approaching trough move overhead. While overall forcing and flow
aloft should be modest south of the primary upper trough, isolated
thunderstorms are possible within the warm advection regime through
the afternoon and into the evening/overnight hours.

Veering hodographs and a subtle increase in deep-layer shear should
favor some storm organization with convection across southeast TX
into far western LA. Wind fields will be weak, but slightly enlarged
low-level hodographs (ESRH 100-200 m2/s2) and a cellular storm mode
could favor transient supercell structures along with occasionally
organized multicells. A brief tornado and marginally severe hail are
possible with the stronger updrafts. While any sustained severe risk
is likely to be contingent upon sufficient warming for surface-base
buoyancy, at least a low-end risk is possible from late afternoon
through much of the overnight hours ahead of the cold front.

As the cold front moves south from the Red River into central TX
this afternoon and into the evening, additional storms are likely to
form along and behind it as the front encounters the northern
fringes of the moisture plume. Despite sufficient buoyancy (MLCAPE
500-1000 J/kg), the undercutting nature of the surging front should
tend to limit storm intensity. Still, sufficient deep-layer shear
(35-45 kt) could support a few stronger clusters as a broken line
develops and surges south. Isolated hail, and perhaps some strong
gusts are possible as the front is expected to quickly move toward
the coast and reach the Gulf early Sunday morning.

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 OVER MUCH OF
EASTERN TEXAS INTO WESTERN LOUISIANA...

...SUMMARY...
Isolated severe thunderstorms are possible across portions of
southeast Texas into western Louisiana Saturday afternoon and
evening.

...Synopsis...
A shortwave trough will move from the central Plains into the Ohio
Valley and upper Great Lakes on Saturday, with a midlevel speed max
strengthening as it expands northeastward from KS to NY. East of
this system, upper ridging will occur over the East as a trough
moves out of the Maritimes.

At the surface, low pressure will move from OK/KS into northern IL
by 00Z, with a cold front trailing southwest across southern MO,
western AR, and northern TX by that time. A large area of high
pressure will remain over much of the eastern CONUS, with a surface
ridge extending into the northern Gulf for much of the day. As such,
low-level moisture return will be limited from the western Gulf into
TX, with low to mid 60s F dewpoints spreading northward ahead of the
cold front. Southwesterly 850 mb winds to around 50 kt will aid
elevated moisture advection across eastern TX/LA, while the stronger
surface-based instability stays generally west of the Sabine River.

...Eastern TX into western LA...
Modest heating is forecast over central TX ahead of the cold front
during the afternoon, though much of eastern TX into LA will remain
cool at the surface. Coincident with peak heating, thunderstorms are
likely to develop as the cold front intercepts the moist plume over
northern TX around 21Z. While profiles aloft will be cool, lapse
rates will not be particularly steep. With MLCAPE perhaps up to 1000
J/kg within the theta-e plume, and effective shear of 30-40 kt,
marginal hail cannot be ruled out. Locally strong gusts may also
accompany the storms as the cold front surges south.

Farther south, additional activity may develop ahead of the cold
front over southeast TX as moisture increases. Low-level wind fields
will be weak overall, but veering with height. As such, a weak/brief
tornado cannot be ruled out. Otherwise, a line of storms will push
south along with the surging cold front, with marginal hail or
locally gusty winds. Severe risk into LA is less certain, as the
surface air mass remains cool with elevated instability. SBCAPE may
develop into southwest LA late in the period, supporting low severe
probabilities.
