...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE CENTRAL GULF COAST...AND PORTIONS OF THE MIDWEST/SOUTHERN GREAT
LAKES...
...SUMMARY...
An isolated threat for damaging winds and a tornado or two may
persist Tuesday along/near the central Gulf Coast, with a separate
area of isolated strong to severe thunderstorms potentially
developing by Tuesday afternoon across parts of the Midwest and
southern Great Lakes.
...Synopsis...
A large-scale upper trough will continue to dominate much of the
CONUS on Tuesday. An embedded mid-level shortwave trough is forecast
to advance quickly northeastward across the OH Valley and Great
Lakes regions through the day. The primary surface low should be
located over the Upper Midwest Tuesday morning, and it should
develop northeastward into Ontario in tandem with the shortwave
trough. A trailing cold front will sweep east-southeastward through
the period across the OH/TN Valleys and parts of the Southeast.
...Central Gulf Coast States...
A line of thunderstorms will likely be ongoing at the start of the
period Tuesday morning across parts of central/southern AL and the
western FL Panhandle. This activity is expected to continue moving
eastward while gradually weakening through the morning, as it
generally outpaces rich low-level moisture return and appreciable
instability. Still, a narrow spatial/temporal window will probably
exist for strong to locally damaging winds with the line, so long as
it can remain near-surface-based. A brief tornado or two also
appears possible focused along/near the coast, as 0-1-km SRH
associated with the southern extent of a 40-60 kt low-level jet
should be sufficient for updraft rotation. An isolated severe threat
may persist into Tuesday afternoon and continue through Tuesday
night across southeastern AL, southwestern GA, and the FL Panhandle
vicinity as mid to upper 60s surface dewpoints attempt to advance
inland across these areas. But, poor lapse rates aloft and limited
daytime heating from cloud cover should temper the development of
any more than weak instability.
...Midwest/Southern Great Lakes...
Beneath a very strong (90-110 kt) mid-level jet and ahead of a
surface cold front, low-topped convection may form relatively early
in the day across eastern IL and western IN. Although low-level
moisture is expected to remain rather limited with surface dewpoints
generally in the low 50s, cold mid-level temperatures coupled with
daytime heating should aid in the development of weak instability
through Tuesday afternoon. Impressive low/mid-level winds veering
with height will support strong deep-layer shear and updraft
organization. Given the forecast strength of the low-level flow,
isolated strong to severe winds appear to be the main threat.
However, sufficient low-level shear to support some risk for a
tornado or two should also be present. Given latest model trends
regarding areas where weak destabilization seems probable, the
Marginal Risk has been expanded westward to include parts of eastern
IL, and northward to encompass much of southern Lower MI. With the
loss of daytime heating, convection should quickly weaken by Tuesday
evening as it continues eastward into western OH.

...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF EXTREME SOUTHEAST ARKANSAS INTO NORTHEAST LOUISIANA AND CENTRAL
MISSISSIPPI...
...SUMMARY...
Severe thunderstorms with a threat for tornadoes and damaging winds
are possible today through tonight from parts of east Texas through
the Lower Mississippi Valley. An instance of hail or a brief tornado
also cannot be ruled out over parts of the Midwest.
...Synopsis...
A mid-level trough will traverse the central U.S. while progressing
eastward and taking on a negative tilt. During the day, a 100+ kt
500 mb jet streak will overspread the central MS Valley as a 994 mb
surface low tracks from the central Plains toward the Great Lakes.
Deep-layer ascent and strong vertical wind shear ahead of the
mid-level trough/surface low will support strong thunderstorm
development along or immediately ahead of an eastward-advancing
Pacific front. Storms should mature over the Mid-South during the
afternoon and progress toward the Gulf Coast states by evening.
Given adequate low-level moisture and overall buoyancy over the
Mid-South, severe thunderstorms are possible. Closer to the surface
low, and where temperatures are coldest aloft, an isolated severe
threat may materialize, particularly over portions of the Midwest.
...Mid South toward the Gulf Coast Region...
Thunderstorms should be ongoing along or immediately ahead of the
Pacific front at the start of the period over portions of central or
eastern TX. Despite widespread cloud cover likely over the entire
warm sector, strong low-level warm-air/moisture advection (driven
primarily by a 60+ kt southerly 850 mb jet) will contribute to a
moistening boundary layer, as cooler temperatures aloft graze the
Mid-South from the north and west. Mid 60s F dewpoints, overspread
by 6-7.5 C/km mid-level lapse rates, will boost SBCAPE into the
500-1000 J/kg range by afternoon peak heating across portions of
extreme eastern TX and LA into southern and central MS. Here, the
overlapping of the intense low-level and mid-level jets will support
rapidly veering/strengthening vertical wind profiles, contributing
to sizeable clockwise-curved low-level hodographs with mid-level
elongation. Effective SRH exceeding 400 m2/s2 will support the
development of strong mesovortices embedded within a squall line.
Damaging gusts and QLCS tornadoes are possible, especially over
eastern LA into southern and central MS, where the best overlap of
SRH and adequate surface-based buoyancy should precede a
well-organized QLCS. A few strong tornadoes are also possible given
the very strong low-level shear. Otherwise, the squall line should
progress eastward into AL with an isolated damaging gust/tornado
threat, though the severe threat should begin to wane sometime
between 09-12Z as the line outpaces the warm sector.
...Portions of the Midwest...
Near the surface low, very cold temperatures aloft will support 8+
C/km mid-level lapse rates beneath 60 F surface dewpoints, boosting
SBCAPE to over 500 J/kg by late morning or early afternoon. Strong
deep-layer ascent will support the development of several
thunderstorms amid deep-layer southerly flow. Speed shear will
contribute to elongated hodographs, and when considering the colder
temperatures aloft, a couple instances of severe hail may accompany
multicellular clusters. Furthermore, strong low-level convergence
north of the surface low, in the vicinity of abundant surface
vertical vorticity, may result in the development of a landspout or
two with one of the stronger multicells as well.

OF EXTREME SOUTHEAST ARKANSAS INTO NORTHEAST LOUISIANA AND CENTRAL
MISSISSIPPI...
...SUMMARY...
Severe thunderstorms with a threat for tornadoes and damaging winds
are possible today through tonight from parts of east Texas through
the Lower Mississippi Valley. An instance of hail or a brief tornado
also cannot be ruled out over parts of the Midwest.
...Synopsis...
A mid-level trough will traverse the central U.S. while progressing
eastward and taking on a negative tilt. During the day, a 100+ kt
500 mb jet streak will overspread the central MS Valley as a 994 mb
surface low tracks from the central Plains toward the Great Lakes.
Deep-layer ascent and strong vertical wind shear ahead of the
mid-level trough/surface low will support strong thunderstorm
development along or immediately ahead of an eastward-advancing
Pacific front. Storms should mature over the Mid-South during the
afternoon and progress toward the Gulf Coast states by evening.
Given adequate low-level moisture and overall buoyancy over the
Mid-South, severe thunderstorms are possible. Closer to the surface
low, and where temperatures are coldest aloft, an isolated severe
threat may materialize, particularly over portions of the Midwest.
...Mid South toward the Gulf Coast Region...
Thunderstorms should be ongoing along or immediately ahead of the
Pacific front at the start of the period over portions of central or
eastern TX. Despite widespread cloud cover likely over the entire
warm sector, strong low-level warm-air/moisture advection (driven
primarily by a 60+ kt southerly 850 mb jet) will contribute to a
moistening boundary layer, as cooler temperatures aloft graze the
Mid-South from the north and west. Mid 60s F dewpoints, overspread
by 6-7.5 C/km mid-level lapse rates, will boost SBCAPE into the
500-1000 J/kg range by afternoon peak heating across portions of
extreme eastern TX and LA into southern and central MS. Here, the
overlapping of the intense low-level and mid-level jets will support
rapidly veering/strengthening vertical wind profiles, contributing
to sizeable clockwise-curved low-level hodographs with mid-level
elongation. Effective SRH exceeding 400 m2/s2 will support the
development of strong mesovortices embedded within a squall line.
Damaging gusts and QLCS tornadoes are possible, especially over
eastern LA into southern and central MS, where the best overlap of
SRH and adequate surface-based buoyancy should precede a
well-organized QLCS. A few strong tornadoes are also possible given
the very strong low-level shear. Otherwise, the squall line should
progress eastward into AL with an isolated damaging gust/tornado
threat, though the severe threat should begin to wane sometime
between 09-12Z as the line outpaces the warm sector.
...Portions of the Midwest...
Near the surface low, very cold temperatures aloft will support 8+
C/km mid-level lapse rates beneath 60 F surface dewpoints, boosting
SBCAPE to over 500 J/kg by late morning or early afternoon. Strong
deep-layer ascent will support the development of several
thunderstorms amid deep-layer southerly flow. Speed shear will
contribute to elongated hodographs, and when considering the colder
temperatures aloft, a couple instances of severe hail may accompany
multicellular clusters. Furthermore, strong low-level convergence
north of the surface low, in the vicinity of abundant surface
vertical vorticity, may result in the development of a landspout or
two with one of the stronger multicells as well.

WW 60 SEVERE TSTM TX 250205Z - 250800Z
URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 60
NWS Storm Prediction Center Norman OK
905 PM CDT Sun Mar 24 2024
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
North Texas
* Effective this Sunday night and Monday morning from 905 PM
until 300 AM CDT.
* Primary threats include...
Scattered large hail and isolated very large hail events to 2
inches in diameter possible
Scattered damaging wind gusts to 65 mph possible
A tornado or two possible
SUMMARY...Strong to severe storms are expected to persist across
parts of North Texas through the late evening and overnight hours,
with some additional development and intensification possible
southwestward toward central Texas later this evening.
The severe thunderstorm watch area is approximately along and 60
statute miles east and west of a line from 25 miles west northwest
of Sherman TX to 20 miles west southwest of Stephenville TX. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU0).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for 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. Severe thunderstorms can and occasionally do produce
tornadoes.
&&
OTHER WATCH INFORMATION...CONTINUE...WW 59...
AVIATION...A few severe thunderstorms with hail surface and aloft to
2 inches. Extreme turbulence and surface wind gusts to 55 knots. A
few cumulonimbi with maximum tops to 450. Mean storm motion vector
25025.

MD 0295 CONCERNING HEAVY SNOW FOR PARTS OF SOUTHEASTERN MINNESOTA AND NORTHERN/CENTRAL WISCONSIN
Mesoscale Discussion 0295
NWS Storm Prediction Center Norman OK
0504 PM CDT Sun Mar 24 2024
Areas affected...Parts of southeastern Minnesota and
northern/central Wisconsin
Concerning...Heavy snow
Valid 242204Z - 250300Z
SUMMARY...A snowband with eventual heavy rates near 1-1.5 inch/hour
is expected to move northward across parts of southeastern Minnesota
and northern/central Wisconsin into tonight. The onset of heavier
rates is expected in the 23Z-04Z time frame.
DISCUSSION...KARX radar data and mesoanalysis as of 22Z indicate a
well-defined frontogenetic band moving northward across far northern
IA, southern MN, and southwest WI. This band is generally located
along the northern periphery of a swath of 40-50-kt 1-km flow per
regional VWP data, which also shows a large clockwise-curved
low-level hodograph -- indicative of strong low-level warm-air
advection. The associated low-level warm nose is yielding melting of
hydrometeors beneath the snowband (and a robust bright-banding
signature), with light to moderate snowfall rates thus far.
With time, the band will continue northward into a region of colder
low-level air, and additional low-level cooling should be aided by
nocturnal effects and wet-bulbing. As a result, snowfall rates
should eventually increase to near 1-1.5 inch/hour as the snowband
moves into the increasingly cold air. There is some uncertainty on
how widespread these heavier rates will be (especially in the next
couple of hours), due to the marginally cold temperatures and much
of the frontogenetic ascent remaining below the dendritic growth
zone. Nevertheless, the heavy-snow potential should increase in the
23Z-04Z time frame.

MD 0298 CONCERNING SEVERE THUNDERSTORM WATCH 59... FOR CENTRAL OKLAHOMA...SOUTHERN KANSAS
Mesoscale Discussion 0298
NWS Storm Prediction Center Norman OK
0702 PM CDT Sun Mar 24 2024
Areas affected...Central Oklahoma...Southern Kansas
Concerning...Severe Thunderstorm Watch 59...
Valid 250002Z - 250200Z
The severe weather threat for Severe Thunderstorm Watch 59
continues.
SUMMARY...Isolated large hail and a few strong wind gusts will be
possible this evening. The threat is expected to be too isolated for
weather watch issuance, to the east of the current watch.
DISCUSSION...The latest high-resolution radar from Oklahoma City
shows a north-to-south corridor of convection across west-central
Oklahoma, where a couple severe storms are ongoing. The airmass
ahead of this convection is weakly unstable, with MLCAPE generally
around 500 J/kg. Water vapor imagery suggests that a subtle
shortwave trough is moving through central Oklahoma. This feature
should continue to provide support for continued convective
development for a couple more hours. Mesoscale analysis from the RAP
currently has strong deep-layer shear in place across much of
central Oklahoma, suggesting that an isolated severe threat will
continue this evening. However, as the storms move further east into
weaker instability, any severe threat should become increasingly
isolated. Large hail and a few damaging wind gusts will be possible,
before the severe threat continues to downtrend further.
