WW 48 TORNADO AL LA MS CW 112355Z - 120700Z
URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 48
NWS Storm Prediction Center Norman OK
655 PM CDT Wed Mar 11 2026
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
West-Central and Southwest Alabama
Southeast Louisiana
Southern and Southeast Mississippi
Coastal Waters
* Effective this Wednesday night and Thursday morning from 655 PM
until 200 AM CDT.
* Primary threats include...
A couple tornadoes possible
Scattered damaging wind gusts to 70 mph likely
Isolated large hail events to 1 inch in diameter possible
SUMMARY...An organizing band of strong to severe thunderstorms is
forecast to move east across the Watch this evening into the early
overnight hours. Damaging straight-line winds and a tornado risk
will probably accompany the more intense portions of the squall
line. Additionally, a couple of supercells ahead of the band are
also possible and may yield an all hazard risk.
The tornado watch area is approximately along and 100 statute miles
east and west of a line from 45 miles northeast of Meridian MS to 25
miles southwest of Houma LA. For a complete depiction of the watch
see the associated watch outline update (WOUS64 KWNS WOU8).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.
&&
OTHER WATCH INFORMATION...CONTINUE...WW 45...WW 47...
AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 1 inch. Extreme turbulence and surface wind
gusts to 60 knots. A few cumulonimbi with maximum tops to 450. Mean
storm motion vector 24035.

MD 0226 CONCERNING TORNADO WATCH 48... FOR PARTS OF SOUTHEASTERN LOUISIANA AND MISSISSIPPI AND SOUTHWESTERN ALABAMA
Mesoscale Discussion 0226
NWS Storm Prediction Center Norman OK
0939 PM CDT Wed Mar 11 2026
Areas affected...parts of southeastern Louisiana and Mississippi and
southwestern Alabama
Concerning...Tornado Watch 48...
Valid 120239Z - 120445Z
The severe weather threat for Tornado Watch 48 continues.
SUMMARY...Occasional brief tornadoes and locally damaging wind gusts
will remain possible with a cluster of storms overspreading the
region through midnight-2 AM CDT.
DISCUSSION...The organized convective system, with at least a couple
of embedded meso beta scale lower/mid-tropospheric cyclonic
circulations and occasionally intensifying meso gamma scale cyclonic
circulations closer to the surface, is generally being maintained.
This is likely being supported by inflow of boundary-layer based
CAPE up to around 1000 J/kg, within a narrow corridor of better
low-level moisture return roughly aligned with a 30-35 kt
southwesterly 850 mb jet nosing inland of the Gulf coast.
It appears that this corridor of destabilization and enlarged
low-level hodographs will persist and develop east-northeastward
across southeastern Mississippi through southwestern Alabama into
the 05-07Z time frame, with the eastward progression of the
mid-level short wave across Louisiana. As long as this continues,
occasional brief tornadoes and locally damaging wind gusts will
remain possible.

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0754 PM CDT Wed Mar 11 2026
Valid 120100Z - 121200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE MIDDLE ATLANTIC AND OVER MUCH OF THE GULF STATES...
...SUMMARY...
Isolated to scattered severe thunderstorms are expected tonight from
the Gulf Coast into parts of the Mid-Atlantic.
...01z Update...
Middle Atlantic: Narrow corridor of yet-to-be overturned instability
extends across eastern WV into the Middle Atlantic. Several short
line segments have developed ahead of the primary short wave, but
the leading convection over eastern MD/northern DE into NJ is the
primary concern, as this activity has a bit more buoyancy to work
with than the trailing convection across central PA into western WV.
Strong deep-layer shear remains favorable for organized storms to
spread across this region over the next few hours before ingesting
cooler marine layer near the Atlantic coast.
Gulf States: Expansive MCS has evolved over the lower MS Valley
early this evening. This complex has developed ahead of a
low-latitude upper low over south central TX that is becoming more
negative tilt with time. Exit region of midlevel jet will translate
along the Gulf coast overnight, and this will encourage eastward
propagation through sunrise. 00z sounding from LIX exhibited strong
shear, but a substantial warm layer is noted around 4-5km. This warm
layer should gradually cool as the aforementioned upper low advances
east tonight.
