Severe March 14-17 Severe

TDS crossing I-55. This is going to clip NW Montgomery County and move into Grenada Co near Elliott

We're going to go considerable on that warning. Rotational velocity is quite strong.
TDS also appears to extend to at least 10,000 ft

THIS IS IN MS.

...THERE IS A HIGH RISK OF SEVERE THUNDERSTORMS ALONG A CORRIDOR
FROM CENTRAL MISSISSIPPI INTO NORTHERN/CENTRAL ALABAMA...

...SUMMARY...
A tornado outbreak is expected across the central Gulf Coast States
and Deep South into the Tennessee Valley. Numerous significant
tornadoes, some of which should be long-track and potentially
violent, are expected this afternoon and evening. The most dangerous
tornado threat should begin across eastern Louisiana and Mississippi
during the late morning to afternoon, spread across Alabama late day
into the evening, and reach western parts of the Florida Panhandle
and Georgia Saturday night.

...Central Gulf States/Tennessee Valley Region...

Strong cyclone that is lifting northeast across the upper MS Valley
will eject into northwest Ontario later today as a very strong
mid-level speed max digs southeast across northern Mexico into
south-central TX. Later tonight, this jet will translate into the
central Gulf States with winds in excess of 110kt. In response to
this feature, a surface low should evolve along the trailing
boundary along the TX/LA border early in the period, then track
northeast into western KY by 16/00z. Additionally, an intense LLJ
will evolve by mid day across northern MS and strengthen during the
afternoon as it gradually shifts downstream into AL/middle TN/KY by
early evening. Net result should be for a bit higher moisture
content to advance farther north than previous thought.

Early this morning, an arcing band of scattered supercells extended
across southern IL into eastern AR. More isolated activity has
persisted much of the late evening across portions of MS. Latest
thinking is convective overturning should remain minimal across the
lower MS Valley and this will allow significant destabilization to
materialize ahead of the surface low early in the period. Latest
surface data depicts lower 70s dew points across southern
LA/southwest MS, with mid 60s approaching the south side of the
Memphis metro. Confidence is increasing that a corridor of strong
buoyancy and intense shear will be in place prior to the
aforementioned speed max/short-wave trough. Forecast soundings
exhibit steep mid-level lapse rates with ESRH in excess of 500 m2/s2
across a broad swath of the central Gulf States, especially the
categorical High Risk delineation.

While scattered strong/severe thunderstorms will likely be ongoing
at the start of the period across the western TN Valley, convection
should increase in intensity by late morning across LA as the
leading edge of the approaching short wave begins to influence this
region. Continued boundary-layer heating will lead to subsequent
development and supercells should mature and race northeast as the
flow strengthens. This flow regime favors long-lived tornadoes, and
the parameter space suggests potentially violent, long-track
tornadoes. This activity will grow upscale in both coverage and
intensity through late afternoon as the overall severe complex
shifts downstream. Large hail and damaging winds may also accompany
these storms, but the primary concern today will be the likelihood

for a tornado outbreak, especially across Mississippi into Alabama.

FROM BIRMINGHAM NWS CONCERNING TODAY FOR THE "MAIN EVENT"


National Weather Service Birmingham AL
238 AM CDT Sat Mar 15 2025

BLUF: A prolific severe weather event is expected today, with
multiple rounds of supercells likely through the afternoon hours.
Given the parameter space, tornadoes associated with these
supercells will have the capacity to be violent and long-lived.

Tornado watches and warnings are ongoing to our west, with new
convection already building in WFO Jackson`s southern tier of
counties. These storm will continue to build north, eventually
translating into our first round of severe weather for the day.
However, some of these early storms may end up being suppressed, as
a special 05z balloon from BMX shows a rather stout warm nose
between 850 and 700mb. Even with the suppression, the early
convection will still be capable of producing all modes of severe
weather.

The significant tornado threat will really begin to ramp up around
noon, when the second surface low begins to develop near the
ArkLaTex region, ejecting into the lower Midwest. High-res guidance
continues to indicate rapid destabilization across the warm sector,
with a large portion of our region remaining relatively unphased by
the early convection. In fact, this morning convection could even
aid these afternoon supercells by planting residual boundaries for
them to latch onto. Once the warm nose overhead erodes, and storms
are able to tap into the full environment overhead, any storm that
starts to spin will be capable of producing a tornado. Any one of
these tornadoes will also have the capacity of become strong,

violent, and long-lived.

These supercells will continue to trek east into the evening hours,
remaining somewhat isolated from each other for the majority of the
event. However, things will begin to become more congested as these
storm push past I-65, eventually becoming more linear in shape. Even
with that scenario, storms along the line could retain their
supercell characteristics, keeping the strong tornado threat
lingering through the entirety of our CWA.

Even with storms expected to be ongoing as the sun comes up, there
is still time to prepare for what appears to be a prolific tornado
event across the region. Gather important documents, charge your
devices, and do not hesitate to act when prompted. These storms
could be moving 50+ MPH when a warning is issued, and time will be
of the essence. On a high-end day like today, take every precaution
necessary to protect yourself, and your loved ones.
