Mesoscale Discussion 0367
NWS Storm Prediction Center Norman OK
0820 PM CDT Wed Apr 02 2025
Areas affected...Parts of central Indiana
Concerning...Tornado Watch 99...
Valid 030120Z - 030245Z
The severe weather threat for Tornado Watch 99 continues.
SUMMARY...The tornado and damaging-wind risk is spreading
east-northeastward across central Indiana in Tornado Watch 99.
DISCUSSION...The latest radar data from IND/VWX shows an intense
bowing line segment with an embedded supercell structure tracking
east-northeastward at around 60 kt across central IN. With
moist/unstable inflow for this system (middle 60s dewpoints) and
60-70 kt of line-orthogonal 0-6 km shear (pew IND VWP), this intense
convection will continue to pose a risk of severe wind gusts
(upwards of 80 mph) and embedded tornadoes. Isolated cells
developing ahead of the main line will also pose a risk of
tornadoes, large hail, and damaging winds.
Farther south, semi-discrete supercell clusters are also tracking
east-northeastward within a very favorable environment (350-400
m2/s2 effective SRH and around 1500 J/kg MLCAPE). This activity will
continue to pose a risk of tornadoes, large hail, and damaging winds
as it continues east-northeastward.

Mesoscale Discussion 0366
NWS Storm Prediction Center Norman OK
0745 PM CDT Wed Apr 02 2025
Areas affected...Portions of eastern Indiana into western and
central Ohio
Concerning...Severe potential...Tornado Watch likely
Valid 030045Z - 030245Z
Probability of Watch Issuance...95 percent
SUMMARY...The severe threat will gradually increase across eastern
Indiana into western and central Ohio into the overnight hours.
Tornadoes, damaging winds, and large hail will all be possible. A
Tornado Watch will be issued within the hour (by 0030Z).
DISCUSSION...Along/south of an east/west-oriented warm front
extending across northern IN/OH, an expansive warm/moist sector has
developed (upper 50 to lower 60s dewpoints). Over the next few
hours, a 70-80-kt low-level jet (and associated warm advection) will
overspread the warm sector, promoting a rapid increase in
surface-based thunderstorm development into the overnight hours. The
00Z ILN sounding sampled fairly steep deep-layer lapse rates and
around 1500 J/kg MLCAPE, along with 40 kt of effective shear and a
large clockwise-curved hodograph (around 350 m2/s2 effective SRH).
As storms overspread this environment, they should quickly intensify
into a mix of supercells and organized bowing line segments --
capable of tornadoes, damaging winds, and large hail. A Tornado
Watch will be issued for parts of the area within the hour (by
0030Z).

AR...nwrn MS...wrn TN...wrn KY
Concerning...Tornado Watch 98...
Valid 030033Z - 030230Z
The severe weather threat for Tornado Watch 98 continues.
SUMMARY...A continued gradual increase in potential for damaging
surface gusts, and tornadoes associated with meso-vortices embedded
within the evolving mesoscale convective system, are expected
through 9-10 PM CDT. Additional supercells posing a risk for strong
tornadoes still appear possible across parts of southeastern
Arkansas into the Greater Memphis area.
DISCUSSION...The narrow surface cold pool appears to have
strengthened along a corridor from Texarkana through Little Rock,
Batesville, AR and Poplar Bluff MO, where 2 hourly surface pressure
rises of 2-4 mb were sampled in the 00Z surface obs. A meso low has
developed along the gust front near Cape Girardeau, where a 2
hourly fall in excess of 3 mb was evident. Another may be
developing near/west of Memphis, where another notable fall center
was evident (in excess of 2 mb in 2 hours).
The boundary-layer remains characterized by moderate potential
instability in a narrow corridor within the confluent low-level
regime across southeastern Arkansas toward the Greater Memphis area,
where additional discrete supercell development with potential to
produce a strong tornado remains possible. Farther north into the
lower Ohio Valley this is becoming more unclear as the gust front
begins to overtake initially more discrete storm development.
Regardless, potential for damaging wind gusts and tornadoes with
evolving meso-vortices within the developing mesoscale convective
system are expected to continue a slow eastward progress across
southeastern Arkansas, and areas east of the Mississippi River into
lower Ohio Valley through 02-03Z.

Areas affected...Portions of Lower Michigan
Concerning...Severe potential...Watch possible
Valid 030026Z - 030230Z
Probability of Watch Issuance...40 percent
SUMMARY...Thunderstorms should increase in coverage across portions
of Lower Michigan during the next few hours. The primary concern
would be isolated severe hail, though locally damaging gusts cannot
be entirely ruled out.
DISCUSSION...The latest VWP data from DTX/GRR shows a strengthening
low-level jet and associated warm advection overspreading Lower MI
-- to the north of an east/west-oriented warm front across northern
IN/OH. This will favor an increase in thunderstorm coverage over the
next few hours. The DTX 00Z soundings sampled an environment
marginally supportive of elevated supercell structures embedded
within increasing stratiform rain (around 55 kt of effective shear).
However, marginal elevated buoyancy (880 J/kg MUCAPE) may limit
updraft intensity to an extent. Nevertheless, the risk of isolated
severe hail (around 1 inch) should increase during the next few
hours, and locally damaging winds cannot be entirely ruled out with
any established supercells -- especially farther south closer to the
warm front.

Valid 030100Z - 031200Z
...THERE IS A HIGH RISK OF SEVERE THUNDERSTORMS FROM SOUTHERN
ARKANSAS INTO SOUTHERN ILLINOIS...
...SUMMARY...
A tornado outbreak is ongoing across parts of the lower Mississippi
Valley into the Mid-South and lower Ohio Valley. Numerous tornadoes,
along with multiple EF3+ tornadoes, remain likely. Additionally,
tornadoes, significant severe wind gusts, and large hail to very
large hail remain possible across a broad area from north Texas
northeastward to the southern Great Lakes.
...01z Update...
An elongated corridor of severe thunderstorms has evolved from
southern Arkansas, northeast across the Boot Heel of Missouri into
northern Indiana. Numerous tornadic supercells are noted along this
zone, especially across the High Risk area from southern Arkansas
into southern Illinois. Multiple long-lived tornadoes have likely
produced significant damage in places, and this threat will continue
into the late evening/overnight hours.
Intense LLJ is forecast to translate across the western Tennessee
Valley into the lower Great Lakes, and this will contribute to a
northeastward shift of organized convection after midnight as the
primary short-wave trough ejects toward lower Michigan.
Environmental parameters continue to favor strong tornadoes and
damaging winds, along with large hail.
Upstream across Texas, a secondary low-latitude short-wave trough
will approach far West Texas late in the period. In response to this
feature, LLJ is forecast to increase across the Edwards Plateau by
03/06z, and strengthening is expected as the LLJ shifts toward the
I35 corridor by sunrise. Significant destabilization is expected
into north-central Texas late as moisture surges north. As a result,
supercells are expected to develop and spread east-northeast.
