Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1111 AM CST Thu Nov 21 2019

Valid 221200Z - 231200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
SOUTHEAST TX INTO LA...

...SUMMARY...
Thunderstorms are expected from the southern Plains into the lower
Mississippi Valley Friday. A low probability of locally strong wind
gusts and perhaps a brief tornado will exist from southeast Texas
into Louisiana during the day.

...Southeast Texas into Louisiana...

Showers and thunderstorms will likely be ongoing Friday morning
along and ahead of a surface cold front. This cold front will
stretch from southwest AR into central TX at the beginning of the
period, shifting east/southeast from western LA to the TX Gulf Coast
by 00z. Southerly low level flow ahead of the front will maintain
surface dewpoints in the mid 60s to near 70 F. Cloudiness and shower
activity will limit destabilization, with a narrow corridor of
MLCAPE generally less than 1000 J/kg expected across southeast TX
into LA during the late morning into the afternoon. Lapse rates also
will remain poor, further limiting storm intensity.

However, strong deep layer southwesterly shear will overspread the
region as a shortwave trough shifts from the central/southern Plains
to the mid-MS Valley. Effective shear near 40-50 kt will support
some organized/rotating storm structures. Furthermore, while low
level speed shear is not particularly strong, forecast soundings
indicate small, curved hodographs ahead of the front near the Sabine
River. As a result, an isolated strong to severe storms capable of
locally strong wind gusts and perhaps a tornado will be possible.

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

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 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0212 AM CST Thu Nov 21 2019

Valid 231200Z - 241200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated to widely scattered thunderstorms are expected over a part
of the Southeast States Saturday. Threat for severe weather appears
low at this time.

...Synopsis...

A progressive southern-stream shortwave trough will move through the
Southeast States accompanied by a cold front Saturday. Weak
cyclogenesis is expected over the TN Valley early in the period, and
this low is forecast to weaken as it moves northeast into the
central Appalachians. Secondary cyclogenesis is forecast across NC
and VA overnight as a strong vorticity maximum moves into the base
of the upper trough and interacts with the baroclinic zone.

...Southeast States...

Partially modified Gulf air with surface dewpoints generally in the
low to mid 60s F will advect into the Gulf Coast states Saturday.
This will result in some destabilization, but instability will
remain very marginal (MUCAPE below 500 J/kg) due to widespread
clouds and poor low to mid-level lapse rates. It is likely that
scattered showers with embedded thunderstorms will be ongoing along
the warm conveyor along and just ahead of the cold front, and this
activity will advance east during the day. Thunderstorm coverage
will probably diminish with eastward extent due to more limited
moisture and instability. However, a separate area of thunderstorms
may develop over the coastal Carolinas late Saturday night as the
front intercepts richer low-level moisture. While vertical shear
will be more than adequate to support storm organization, the very
weak thermodynamic environment should remain a limiting factor for
severe storms.
