* Primary threats include...
A few tornadoes possible
Scattered damaging wind gusts to 70 mph possible
SUMMARY...Fast-moving thunderstorms over west Tennessee will track
into the watch area this evening, posing a risk of locally damaging
wind gusts and a few tornadoes.

the watch see the associated watch outline update (WOUS64 KWNS
WOU9).
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 8...
AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 1.5 inches. Extreme turbulence and surface wind

MD 0102 CONCERNING TORNADO WATCH 9... FOR MIDDLE TENNESSEE AND SOUTHERN KENTUCKY
Mesoscale Discussion 0102
NWS Storm Prediction Center Norman OK
0913 PM CST Sat Feb 15 2025
Areas affected...Middle Tennessee and Southern Kentucky
Concerning...Tornado Watch 9...
Valid 160313Z - 160415Z
The severe weather threat for Tornado Watch 9 continues.
SUMMARY...Severe threat continues within WW009.
DISCUSSION...A line of thunderstorms continues to track east
northeast across portions of Middle Tennessee and southern Kentucky.
Storms embedded within the line have shown transient rotation, with
instances of hail up to golf ball and damaging wind. With eastward
advancements, storms have begun outpacing the more unstable air
mass. Dew points into the 60s remain as far north as far southern
Kentucky. However, 00z sounding from BNA shows low level CIN and
poor distribution of MLCAPE within the profile. Across east
Tennessee, dew points in the mid to upper 50s are more common with
temperatures cooling rapidly with eastward extent.
Shear profiles remain very strong, with deep layer shear around
45-50 kts and 0-3 km SRH around 600 m2/s2. Despite the decreasingly
favorable thermal environment, deep layer shear will likely favor
continued organization and risk for damaging wind, given recent
trends in a more elongated line with bowing segments. Embedded
MESOVORTEX within the line may still pose a risk for tornadoes.

MD 0101 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR CENTRAL GULF STATES
Mesoscale Discussion 0101
NWS Storm Prediction Center Norman OK
0837 PM CST Sat Feb 15 2025
Areas affected...Central Gulf States
Concerning...Severe potential...Watch likely
Valid 160237Z - 160330Z
Probability of Watch Issuance...95 percent
SUMMARY...New Tornado Watch will be issued across the central Gulf
States by 0330z.
DISCUSSION...Fast-moving upper trough is ejecting across eastern
OK/TX and the associated cold front is surging through the lower MS
Valley region, currently stretching from eastern AR into
south-central TX. An expansive corridor of pre-frontal convection
has developed ahead of the short wave from the lower OH Valley,
southwest into central LA. Over the last hour or so, thunderstorm
activity appears to be gradually sharpening across the lower MS
Valley with at least two bands of strong/severe convection that will
soon spread east of the MS River. Surface temperatures remain in the
lower 70s across much of the warm sector immediately ahead of this
activity, and mid 60s dew points have returned to central MS. While
tornado activity has been somewhat sparse to this point, intense
0-3km SRH warrants concern. Latest thinking is updrafts may continue
to mature and longer-lived supercells are certainly possible, though
an organized QLCS will be the primary storm mode. This MCS will
advance across the remainder of the central Gulf States later
tonight.

MD 0100 CONCERNING TORNADO WATCH 8... FOR WESTERN TENNESSEE AND SOUTHWESTERN KENTUCKY
Mesoscale Discussion 0100
NWS Storm Prediction Center Norman OK
0609 PM CST Sat Feb 15 2025
Areas affected...western Tennessee and southwestern Kentucky
Concerning...Tornado Watch 8...
Valid 160009Z - 160145Z
The severe weather threat for Tornado Watch 8 continues.
SUMMARY...Tornado threat continues within WW008. Threat will
continue downstream into portions of Middle Tennessee and Western
Kentucky.
DISCUSSION...A broken line of thunderstorms has shown an uptick in
intensity over the last hour across the Arkansas/Tennessee border.
Line embedded supercells are observed, with activity ahead of the
main line also exhibiting rotation. The low level jet, with axis
currently from central LA to middle TN/southern KY, is progged to
continue strengthening through the evening, with low level shear
becoming more favorable. This strong southerly flow has also ushered
in deeper moisture and a more favorable air mass across western
Tennessee, steadily approaching southern Kentucky.
Given the progress of the main line, maintenance of individual cells
ahead of the line will be difficult. However, deep layer shear of
50-55 kts will continue to support line embedded mesocyclones and
potential for damaging wind and tornadoes. This threat is spreading
eastward and will likely necessitate a downstream watch into
southern Kentucky soon.

MD 0099 CONCERNING TORNADO WATCH 8... FOR LOWER MISSISSIPPI VALLEY
Mesoscale Discussion 0099
NWS Storm Prediction Center Norman OK
0549 PM CST Sat Feb 15 2025
Areas affected...Lower Mississippi Valley
Concerning...Tornado Watch 8...
Valid 152349Z - 160115Z
The severe weather threat for Tornado Watch 8 continues.
SUMMARY...Pre-frontal supercells may mature over the next few hours
as they track across northeast LA into west-central MS. Tornado risk
will increase if this occurs. Will continue to monitor for possible
Tornado Watch immediately downstream into Mississippi.
DISCUSSION...Over the last hour or so, pre-frontal convection has
gradually increased across central into northeast LA, especially
from Rapides to Caldwell Parish. This activity is not too organized
at this time but there is some concern these storms may continue to
mature within a strongly sheared environment, immediately ahead of
the frontal convection. If so, tornado risk may increase
accordingly.

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0656 PM CST Sat Feb 15 2025
Valid 160100Z - 161200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS IN THE TN/LOWER
MS VALLEYS AND THE DEEP SOUTH...
...SUMMARY...
Severe thunderstorms are expected through early morning Sunday
across parts of the Tennessee/Lower Mississippi Valleys and the Deep
South. Tornadoes, a few of which could be strong, and scattered to
widespread damaging winds should be the primary threats.
...TN/Lower MS Valleys and the Deep South...
Broken linear convection is ongoing from the Mid-South to the Lower
Sabine Valley, along and just ahead of a surface cold front that is
expected to move east tonight. A relatively broad warm-moist sector
heated into the 70s and low 80s earlier, and has supported a plume
of MLCAPE 500-1500 J/kg. As a well-defined shortwave trough over the
Lower MO Valley to northeast TX progresses east into the Central OH
Valley and Deep South, an extensive QLCS will evolve from the TN
Valley to the central Gulf Coast. Pre-QLCS convection across LA
should persist with eastern extent across the Gulf Coast States.
Very strong 850-700 mb winds (65-80 kt) should be prominent from the
Ark-La-Miss to central parts of MS/AL northward. This flow regime
should support widespread strong gusts with embedded severe swaths,
yielding scattered to widespread damaging winds, along with a threat
for mesovortex tornadoes. After coordination with WFO BMX, have
expanded the level 3-ENH risk northeastward in AL. The fast-moving
QLCS will eventually outpace the warm-moist sector in the TN
Valley/southern Appalachian vicinity.
Farther south, the 00Z JAN sounding sampled a more deeply mixed air
mass than progged by operational guidance, with mean-mixing ratios
near 11 g/kg. Rich boundary-layer moisture closer to the Gulf Coast
suggests that semi-discrete supercells merging into the southern
portion of the QLCS would be the more favored scenario for a few
longer-lasting/strong tornadoes overnight.
