Recommended Posts

Mobile County, Alabama and southeastern Mississippi counties near Hattiesburg and Laurel have already several reports of radar observed or confirmed tornadoes with these isolated supercells coming off the Gulf or remnant energy from yesterday's severe storms across Southeast Texas and Louisiana. 

This is the beginning rounds of possibly several waves of severe thunderstorms ongoing now through tonight and likely until Sunday

There are a couple of rotating supercells coming off the Gulf of Mexico that are spawning quick spin-up tornadic waterspouts and tornadoes. Until 5:15PM CST there is a Tornado Warning for the southeastern portion of Mobile County from one of these supercells coming off the Gulf.  It appears to have had a history of tornadic waterspouts from the prior Special Marine Advisories and Warnings mentioning a sighted waterspout.

  Day 1 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1159 PM CST Fri Dec 27 2024

   Valid 281200Z - 291200Z

   ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
   FAR EAST TEXAS...LOUISIANA...CENTRAL AND SOUTHERN MISSISSIPPI...AND
   FAR WESTERN ALABAMA...

   ...SUMMARY...
   An outbreak of severe storms with tornadoes, wind damage, and large
   hail is expected today from parts of the southern Plains, eastward
   into the lower Mississippi Valley and central Gulf Coast states.
   Several long-track strong tornadoes are expected.

   ...Tornado Outbreak Likely This Afternoon and Evening Across the
   Lower Mississippi Valley and Central Gulf Coast States...

   A mid-level trough will move quickly eastward across the southern
   Plains today, as an associated mid-level jet moves through the base
   of the trough. A surface low will deepen across northeast Texas as a
   warm front advances northward into the Ark-La-Tex. Scattered
   thunderstorms will first develop near the surface low during the
   morning, as surface temperatures warm and as large-scale ascent
   rapidly increases due to the approaching system. Isolated large hail
   will be the initial severe threat across northeast Texas. The exit
   region of a 60 to 80 knot mid-level jet will overspread much of east
   Texas around midday, where more vigorous thunderstorms are expected
   to develop during the early afternoon. These storms will have
   potential to produce severe wind gusts, isolated large hail and
   tornadoes. A severe MCS appears likely to intensify and organize as
   this activity increases in coverage.

   Further to the east, an axis of maximized low-level moisture is
   expected to be in place during the early afternoon, oriented from
   southern Louisiana into western Mississippi. Surface dewpoints along
   and near the axis will be in the mid to upper 60s F. The moist axis
   will be aligned with a strengthening low-level jet. Scattered
   discrete cells are expected to initiate across the undisturbed moist
   sector during the afternoon, with several vigorous storms moving
   east-northeastward across the central Gulf Coast states. RAP
   forecast soundings near the exit region of the mid-level jet, from
   central Louisiana into central Mississippi, show steep mid-level
   lapse rates around 8 C/km, with 0-6 km shear in the 45 to 55 knot
   range. This environment will support supercell development, with a
   potential for strong tornadoes, wind damage and isolated large hail.
   Forecast soundings in the early to mid afternoon near the low-level
   jet from eastern Louisiana into south-central Mississippi show
   backed surface winds to the southeast, and increase 0-3 km
   storm-relatively helicity to around 300 m2/s2. This should be
   favorable for tornadic supercells. The low-level jet is forecast to
   move east-northeastward across the central Gulf Coast states in the
   mid to late afternoon. Supercells that can tap the higher surface
   dewpoints and stay within or near the axis of the low-level jet
   should be able to produce long-track EF3+ tornadoes, and several of
   these will be possible.

   The severe linear MCS further to the west, is expected to move
   quickly eastward across the lower Mississippi Valley during the
   afternoon, and will likely be accompanied with widespread severe
   wind gusts, with potential for gusts above 65 knots along the more
   intense part of the line. By early evening, this line of severe
   storms is expected to become the dominant feature across the region.
   Widespread wind damage is expected along the leading edge of the
   line from the central Gulf Coast states into southern parts of the
   Tennessee Valley. Tornadoes will be possible with embedded
   supercells within the line, and with line echo wave patterns that
   form. Due to the fast-moving mid-level trough, large-scale ascent is
   expected to support the severe linear MCS from the evening into the
   overnight. A potential for wind damage and tornadoes is expected to
   continue after midnight as the line moves across middle Tennessee
   and Alabama. The MCS with some severe potential, is expected to move
   into the southern Appalachians and northern to central Georgia by
   the end of the period.

It's Broyles tho who thinks every setup is the next "big one"

1300z SPC OTLK disco suggested higher probs 

.Southern Plains to Southern Appalachians and central Gulf
   Coast...
   Convection is increasing in two main regimes either side of the
   warm/marine front:
   1.  Elevated convection to its north over north-central TX,
   predominantly of a hail concern, and forecast to move/expand into
   the Arklatex over the next few hours.  See Severe Thunderstorm Watch
   717 and related mesoscale discussions for near-term details.
   2.  Warm-sector thunderstorms building gradually from east TX across
   parts of LA to southern MS.  This activity will pose a threat for
   tornadoes, isolated hail, and occasional severe gusts.  See SPC
   Mesoscale discussions 2294 and 2295, with watches likely over these
   areas today as well.

   Peak tornado and severe-gust potential should be from this afternoon
   into tonight, in and near the "Moderate" and "Enhanced" areas.
   Perhaps the greatest uncertainty at this time is coverage of
   supercells in the warm sector during peak instability this afternoon
   and into evening, following the morning episode, given 1) the need
   for recovery behind earlier activity and 2) subtle and gradual
   boundary-layer forcing/convergence would be the main factor
   contributing to their development.  A broad area of favorable
   moisture, represented by mid-60s to near 70 F surface dewpoints,
   will contribute to peak MLCAPE in the 2000-2500 J/kg range from east
   TX to southwestern MS, and around 1000-1500 J/kg from central MS
   into central/southern AL where diurnal heating will be less a factor
   than theta-e advection for preconvective destabilization. 
   Hodographs will favor supercells and tornado potential during the
   day -- especially near the marine/warm front -- but largest after
   00Z east of the Mississippi River where a 45-60-kt LLJ will overlap
   at least marginally surface-based inflow parcels.  SRH of 150-250
   J/kg in the lowest 1/2 km, and 200-400 J/kg in the effective-inflow
   layer, should be attainable.

   Any sustained, discrete supercell in this environment will pose a
   threat for cyclic, strong tornado production.  As the primary
   convective band organizes and moves into increasing moisture and
   LLJ-enlarged hodographs in low levels this evening, embedded
   LEWP/bowing features may produce both severe gusts and tornadoes. 
   The cumulative tornado threat suggests maintaining "moderate" level
   probabilities with this outlook cycle, but enough uncertainty
   remains to preclude a greater unconditional risk area.  As the event
   proceeds through the overnight hours, one or two dominant QLCSs
   should continue across AL and into portions of GA and the FL
   Panhandle, with a threat persisting for embedded severe gusts and at
   least a few tornadoes.

Day 1 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1029 AM CST Sat Dec 28 2024

   Valid 281630Z - 291200Z

   ...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON
   AND TONIGHT ACROSS PORTIONS OF EAST TEXAS...LOUISIANA...CENTRAL AND
   SOUTHERN MISSISSIPPI...AND SOUTHWESTERN ALABAMA....

   ...SUMMARY...
   Tornadoes (some strong with at least EF2 damage possible), severe
   gusts and hail are expected today into tonight. The threat area will
   shift eastward from parts of north and central Texas early, across
   east Texas and the lower Mississippi Valley today, then over the
   Tennessee Valley, parts of Georgia, and the central Gulf Coast
   tonight.

   ...East TX to AL/GA...
   A powerful mid-level shortwave trough and associated 80-90 knot jet
   max will rotate quickly eastward across TX today and become
   negatively-tilted as it tracks into the lower MS Valley this
   evening.  Ample low-level moisture (dewpoints in the mid 60s to
   lower 70s) is in place ahead of this system across east TX, much of
   LA, and central/southern MS.  Morning convection is slowly weakening
   across the warm sector, and low-clouds will continue to erode.  This
   will help to develop a corridor of moderate instability with MLCAPE
   values of 1500-2000 J/kg.  This will set the stage for a significant
   severe weather event through the evening as supercells and bowing
   structures form over east TX and race eastward across LA into MS.  

   The co-location of the mid-level jet, strengthening winds in the
   low-levels, surface cyclogenesis, and ample moisture provide a
   synoptically-evident setup for all severe hazards through the
   evening.  The corridor of greatest concern will be late afternoon
   through the evening from central LA into central MS.  Considered an
   upgrade to HIGH for this area, but will maintain the ongoing MDT
   after consultation with local WFOs.  Strong and long-tracked
   tornadoes and widespread damaging winds are possible in this region,
   with the primary uncertainty regarding storm-mode and linear forcing
   mechanisms.

   Activity will spread across AL overnight, where slightly less
   low-level moisture will somewhat decrease the overall severe threat.
    Nevertheless, an active squall line with damaging wind potential
   and embedded rotating storms/tornado threat will likely persist.
