Day 3 Convective Outlook

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER A PORTION
OF THE LOWER MISSISSIPPI VALLEY AND SOUTHEAST STATES...
...SUMMARY...
A potential outbreak of severe storms including strong tornadoes,
large hail and damaging wind will exist Thursday afternoon into the
overnight across a portion of the lower Mississippi Valley and
Southeast States.
...Lower Mississippi Valley and Southeast States...
A robust shortwave trough will move from southern TX early Thursday
northeast through the lower MS Valley during the day and into the OH
Valley overnight. Thursday morning a cold front will extend from the
Great Lakes southwest to a weak surface low in eastern TX, then
south into the western Gulf. In response to the ejecting shortwave
trough, the cyclone is forecast to undergo significant deepening as
it develops northeast during the day. A cold front will accelerate
through the lower MS Valley and into the Southeast States, while a
warm front initially from northeast TX into northern LA and central
MS lifts northward to near the TN border by evening.
It is likely that elevated storms will be ongoing in warm advection
regime across northern MS, AL and TN. This activity is expected to
continue lifting northward allowing for destabilization from the
south with time. Rich low-level moisture with upper 60s to near 70 F
dewpoints will advect northward through warm sector contributing to
moderate instability with up to 2000 J/kg MLCAPE. Potential will
exist for discrete storms to develop in the warm sector as the
boundary layer destabilizes during the afternoon. Vertical wind
profiles with very strong shear and large 0-1 km hodographs will
support supercells capable of producing strong tornadoes and large
hail. Activity will spread northeast through the lower MS valley
during the day and into the TN Valley by late afternoon into the
evening. Additional storms may also develop along the cold front
with linear structures capable of damaging wind.
...OH Valley...
Widespread early storms during the first half of the day lower
confidence in more than A SLGT/MRGL risk for this region at this
time. However, some destabilization is expected by late day or
during the evening. Potential will exist for a line of storms to
develop along the cold front with damaging wind and QLCS tornadoes
the main threats. The SLGT risk may need to be expanded farther
north in later outlooks.

Vaya cómo está el tema en estos momentos en algunas zonas de los estados del SE de EEUU, la mayoría de los avisos del National Weather Service ahora centrados en Alabama. Multitud de "Tornado Warning" y varias "Tornado Emergency"
Hay varios directos en youtube que están siguiendo al detalle, también videos en twitter
No me gustaría vivir en esas zonas...
