The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Southwest Illinois
Western Kentucky
Eastern Missouri
* Effective this Tuesday afternoon and evening from 130 PM until
900 PM CDT.
* Primary threats include...
Scattered large hail and isolated very large hail events to 2
inches in diameter possible
Isolated damaging wind gusts to 70 mph possible
SUMMARY...Mostly elevated storms, driven by strong instability
aloft, will continue to move east-northeastward into the region this
afternoon and early evening. Large hail will be the most common
hazard, with localized wind damage a possibility as well.
The severe thunderstorm watch area is approximately along and 60
statute miles east and west of a line from 45 miles northeast of
Vichy MO to 35 miles east southeast of Poplar Bluff MO. For a

WW 171 TORNADO OK TX 281805Z - 290200Z

URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 171
NWS Storm Prediction Center Norman OK
105 PM CDT Tue Apr 28 2026
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
Southern Oklahoma
North Texas
* Effective this Tuesday afternoon and evening from 105 PM until
900 PM CDT.
* Primary threats include...
A couple tornadoes possible
Widespread large hail and scattered very large hail events to 4
inches in diameter expected
Scattered damaging winds likely with isolated significant gusts
to 80 mph possible
SUMMARY...Rapid development of intense storms/supercells is expected
through the afternoon, especially in vicinity of a surface triple
point and modifying outflow boundary. Given the extreme instability
and strong mid/high-level winds, these supercells will be capable of
very large hail, potentially in excess of baseball size. There will
also be some tornado potential, especially given the influence of
the aforementioned boundary, and some early evening increase in
low-level shear. Eventually, damaging wind potential may also
increase, including the possibility of destructive wind-driven hail
as storms progress east-southeastward.
The tornado watch area is approximately along and 80 statute miles
north and south of a line from 70 miles southwest of Wichita Falls
TX to 50 miles east southeast of Durant OK. For a complete depiction
of the watch see the associated watch outline update (WOUS64 KWNS
WOU1).

MD 0606 CONCERNING TORNADO WATCH 170...177... FOR MUCH OF ARKANSAS...NORTHWEST LOUISIANA...NORTHEAST TEXAS...SOUTHEAST OKLAHOMA

Mesoscale Discussion 0606
NWS Storm Prediction Center Norman OK
0552 PM CDT Tue Apr 28 2026
Areas affected...Much of Arkansas...northwest Louisiana...Northeast
Texas...Southeast Oklahoma
Concerning...Tornado Watch 170...177...
Valid 282252Z - 290045Z
The severe weather threat for Tornado Watch 170, 177 continues.
SUMMARY...Multiple clusters of thunderstorms will track into western
AR this evening, with coverage of other storms increasing toward
sunset.
DISCUSSION...Three distinct clusters of severe/supercell storms are
present this afternoon over OK/AR. One is southeast of FYV, one
near FSM, and a third near IDA. These storms will track eastward
for several more hours into a very moist and moderately unstable air
mass. Forecast soundings and the LZK VAD profile suggest sufficient
low-level and deep-layer shear for continued supercell storm
structures and a risk of all severe modes. The low-level jet is
expected to strengthen this evening around dusk, resulting in
increased coverage of storms, and increasing the risk of a few
tornadoes.
New tornado watch #177 has just been issued for this area until 06z.

MD 0605 CONCERNING TORNADO WATCH 173... FOR CENTRAL MISSISSIPPI INTO SOUTHERN ALABAMA

Mesoscale Discussion 0605
NWS Storm Prediction Center Norman OK
0550 PM CDT Tue Apr 28 2026
Areas affected...central Mississippi into southern Alabama
Concerning...Tornado Watch 173...
Valid 282250Z - 290045Z
The severe weather threat for Tornado Watch 173 continues.
SUMMARY...The convective environment remains favorable or severe
thunderstorms across central Mississippi into parts of southern
Alabama.
DISCUSSION...Latest radar imagery from KDGX and KGWX shows
intensification of a supercell (including a notable three-body
scatter spike) north of the Jackson, MS area. Although this storm is
likely elevated based on the placement of an outflow boundary (noted
in surface observations), a recent 21 UTC sounding from JAN sampled
sufficient MUCAPE for robust convection, even when accounting for
near-storm conditions within the cold pool. This sounding also
sampled effective bulk shear values on the order of 50-60 knots,
which is highly favorable for organized convection. As demonstrated
by the recent trends in the supercell north of Jackson, MS, this
environment should continue to support intensification of ongoing
elevated storms and/or development of new convection over the next
several hours.

MD 0604 CONCERNING TORNADO WATCH 174... FOR EXTREME NORTHEAST ARKANSAS AND THE MISSOURI BOOTHEEL

Mesoscale Discussion 0604
NWS Storm Prediction Center Norman OK
0526 PM CDT Tue Apr 28 2026
Areas affected...Extreme northeast Arkansas and the Missouri
Bootheel
Concerning...Tornado Watch 174...
Valid 282226Z - 290000Z
The severe weather threat for Tornado Watch 174 continues.
SUMMARY...A supercell migrating across far southeast Missouri and
northeast Arkansas may pose a locally higher severe threat over the
next 1-2 hours.
DISCUSSION...Surface observations across the MS Valley show a
stationary boundary/outflow draped across northern AR into KY. A
supercell with a history of producing severe hail and gusts up to 70
mph is approaching this boundary from the northwest along the
eastern MO/AR border. Although MRMS 50 dBz echo tops depict a recent
weakening trend with this storm, regional radar imagery has recently
begun to sample strengthening mid-level flow within the storm
(though precise feature identification is difficult given the
storm's distance from the nearest RDA). Further intensification
appears possible as the storm reaches the boundary where low-level
SRH is enhanced and a more moist/buoyant air mass resides on the
immediate warm side. This may support a localized corridor of higher
severe hail, wind, and tornado potential within the next 1-2 hours.

MD 0603 CONCERNING TORNADO WATCH 174... FOR WESTERN AND MIDDLE TENNESSEE INTO SOUTHERN KENTUCKY

Mesoscale Discussion 0603
NWS Storm Prediction Center Norman OK
0451 PM CDT Tue Apr 28 2026
Areas affected...western and Middle Tennessee into southern Kentucky
Concerning...Tornado Watch 174...
Valid 282151Z - 282345Z
The severe weather threat for Tornado Watch 174 continues.
SUMMARY...A severe threat is expected to persist downstream across
western and middle Tennessee and possibly into parts of southern
Kentucky as an MCV migrates east through early evening.
DISCUSSION...Latest KNQA imagery shows a developing MCV near north
of the Memphis, TN area. Additionally, swaths of severe wind have
been noted in velocity imagery in the vicinity of the MCV. This
feature is expected to continue east/northeast over the next few
hours through an axis of higher MLCAPE values located downstream
across middle TN into southwest KY where surface dewpoints remain in
the mid 60s to low 70s. Although downstream VWPs show more meager
low-level helicity compared to locations further west/southwest,
sufficient hodograph elongation through a deep layer appears
sufficient to maintain organized convection - most likely in the
form of convective bands/clusters capable of producing severe winds
and perhaps embedded circulations. Downstream watch issuance will
likely be needed as this activity approaches the eastern bounds of
WW 174.

MD 0602 CONCERNING TORNADO WATCH 171... FOR NORTH CENTRAL TEXAS

Mesoscale Discussion 0602
NWS Storm Prediction Center Norman OK
0450 PM CDT Tue Apr 28 2026
Areas affected...North Central Texas
Concerning...Tornado Watch 171...
Valid 282150Z - 282315Z
The severe weather threat for Tornado Watch 171 continues.
SUMMARY...A cluster of intense supercell thunderstorms will track
southeastward across the Dallas/Fort Worth metro areas over the next
couple of hours. Very large hail, damaging winds, and a tornado or
two are expected.
DISCUSSION...A line segment of embedded supercells extends from
northeast of Breckenridge to west of Denton TX, moving southeastward
at 25 knots. These storms have produced several reports of severe
hail in the last 1-2 hours, including 2 inch hail in Jack county.
The air mass ahead of these storms is very moist and unstable with
dewpoints in the mid 70s and MLCAPE values approaching 4000 J/kg.
Effective shear values over 50 knots and mid-level lapse rates >8.0
C/km suggest continued supercell structures capable of very large
hail. Given the quasi-linear nature of this cluster of storms,
there is the potential for the development of one or more bowing
structures capable of damaging winds. Also, while low-level winds
are not particularly strong, recent VAD profiles suggest that
slightly backed surface winds and considerable hodograph curvature
in the lowest 2km are contributing to 0-3km SRH over 200 m2/s2,
suggesting a risk of a tornado or two this evening.

SPC 2000Z Day 1 Outlook

Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0300 PM CDT Tue Apr 28 2026
Valid 282000Z - 291200Z
...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS NORTH
TEXAS...
...SUMMARY...
Multiple rounds of severe thunderstorms will occur across parts of
the southern Plains into the lower Mississippi/Tennessee Valleys and
Southeast through this evening. Very large to giant hail (2-4+
inches), swaths of severe/damaging winds, and a few tornadoes are
all possible.
...20Z Update...
The previous forecast remains on track, and only minor adjustments
were made with this update. Most noteworthy, the CIG2 (intensity
level 2/2) hail area was expanded northward into south-central OK,
where robust splitting supercells are evolving in an environment
characterized by 2500-3000 J/kg MLCAPE and around 50 kt of effective
shear. These storms will continue to pose a risk of very large hail
through the afternoon. In north TX, a corridor of relatively higher
tornado potential is evident along a remnant outflow boundary --
where low-level shear is locally enhanced. Refer to Tornado Watch
171 and MCD 599 for more information.
..Weinman.. 04/28/2026
.PREV DISCUSSION... /ISSUED 1151 AM CDT Tue Apr 28 2026/
...Southern Plains to Lower Mississippi Valley/Southeast...
Have upgraded portions of North Texas to a Moderate Risk for what is
anticipated to be a semi-focused sub-regional corridor of supercells
including very large hail potential along with some damaging
wind/tornado risk centered on mid-afternoon through
early/mid-evening.
First, a loosely organized complex of storms continues to progress
east-northeastward along the Red River of southeast
Oklahoma/northeast Texas and broader parts of eastern Oklahoma at
late morning. Additional increasingly surface-based development
seems probable on this near-frontal zone and associated moist axis
and thermal gradient that extends east-northeastward to the
Mid-South/ArkLaMiss. This may include supercells as well as the
possibility of an upscale-growing complex. Other initially elevated
severe storms are expected to continue and increase today from
northeast Oklahoma across the Ozarks toward parts of the
Mid-South/Mississippi Valley. Large hail is the initial risk, but a
surface-based storm risk could develop pending boundary layer
warming.
Broadly speaking outside on ongoing storms, a strongly unstable
airmass exists across the southern Plains to the ArkLaTex, along and
near a slowly retreating/northward-returning warm front. This is
beneath relatively strong winds aloft, particularly in
mid/high-levels based on morning upper-air data. Additional intense
surface-based convective development is forecast near the triple
point in north-central Texas towards the ArkLaTex this afternoon,
where extreme instability (4000+ J/kg MLCAPE) and very strong
deep-layer shear (50-60+ kt) will support the potential for multiple
intense supercells. Very large to giant hail (2-4+ inches) may occur
with the strongest supercells given the overall very favorable
environment and presence of steep mid-level lapse rates. Some
tornado threat may also exist with these supercells, even though
low-level shear is not forecast to be overly strong.
Additional severe storms are expected as far east as Mississippi and
Alabama today -- see Mesoscale Discussion 594 for short-term
details. An additional secondary round of upscale-growing storms
with increasing damaging wind potential could also move into this
same region late today, or more so tonight.

0230 PM CDT Tue Apr 28 2026
Valid 301200Z - 011200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PARTS OF
SOUTHWEST AND SOUTH-CENTRAL TEXAS...
...SUMMARY...
Strong to locally severe thunderstorms are possible across parts of
southwest and south-central Texas on Thursday.
...Southwest into central TX...
A mid/upper-level low initially off of the Baja California coast is
forecast to eject eastward as a shortwave across northern Mexico,
and approach Far West Texas late in the period. A belt of moderate
to strong midlevel westerlies will be maintained downstream of this
system across much of TX. Easterly post-frontal low-level flow will
maintain relatively favorable moisture across southwest TX, though
somewhat weaker midlevel lapse rates (compared to previous days) may
limit MUCAPE to the 1000-2000 J/kg range. While weaker than previous
days, this buoyancy magnitude would still be conditionally favorable
for organized convection, given the presence of moderate to strong
deep-layer shear.
Details of storm coverage and evolution through the period remain
uncertain. Relatively vigorous elevated convection could support
some isolated hail potential, especially if early-day storms can be
maintained through the day, or with any diurnal surface-based
development. Storm coverage will likely tend to increase by Thursday
night, in response to the approaching shortwave trough. While
convective mode may quickly become complex late in the period, some
threat for hail or localized severe gusts could accompany the
strongest storms. Given the potential for one or more rounds of deep
convection within a relatively favorable environment, a Level
1/Marginal Risk has been included for southwest TX and vicinity.

SPC Day 2 Fire Weather Outlook

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0242 PM CDT Tue Apr 28 2026
Valid 291200Z - 301200Z
...Southwest...
A 50-60 knot mid-level jet at the base of an embedded, low-amplitude
short wave within broader west-southwest flow will evolve across the
Southwest and Southern Plains Wednesday. Increasing upper cloud
cover within a Pacific moisture plume will have overspread the
region by Wednesday morning. This should inhibit RH recoveries west
of the NM central mountain chain, preconditioning an already dry
fuel environment for another dry and breezy day. Sustained west
winds of around 15 mph across portions of far eastern AZ into
western NM overlapping RH of 10% or less during the day, will
support an elevated fire weather threat Wednesday. Locally critical
fire weather conditions to include sustained winds of 20-25 mph are
possible mainly in the leeward slopes of more prominent mountain
ranges in southern NM. Farther east, a backdoor cold front will
bring considerable improvement in dewpoints and RH, lowering the
overall fire weather threat across the southern High Plains. Some
slight modifications were made to the highlighted area based on
latest forecast guidance consensus.
...Southern Georgia and Northern Florida...
Increasing west winds south of a surface low moving into the
northeastern U.S. will emerge across portions of the Southeast
Wednesday. The steady west winds and residual dry boundary layer
with minimal Gulf moisture influence will overlap a dry and drought
stressed landscape. This will support elevated fire weather
conditions across portions of southern GA into northern FL where
west winds of around 10 mph, RH of 25-35% and receptive fuels align.
Isolated showers and thunderstorms are possible across the FL
Panhandle and adjacent AL/GA border areas Wednesday afternoon, but
more widespread precipitation is not expected until Wednesday night
into Thursday morning. A slight southward extension into the FL
Peninsula was made to the existing elevated area based on latest
model guidance.
..Williams.. 04/28/2026
.PREV DISCUSSION... /ISSUED 1231 AM CDT Tue Apr 28 2026/
...Synopsis...
A mid/upper level shortwave trough will traverse the Midwest into
the Ohio Valley as an attendant surface low approaches the
Mid-Atlantic. A trailing cold front will progress east of the
Appalachians extending into the Southeast by Wednesday afternoon.
Dry westerly flow south of the advancing cold front is expected to
increase fire weather concerns for portions of southern GA and
northern FL where fuels remain dry. Enhanced mid-level westerly flow
ahead of an approaching Pacific trough will bolster a continued
downslope regime across the Southwest. With preceding days of
fire-effective weather conditions and receptive fuels, fire weather
concerns will persist over central NM to far eastern AZ on
Wednesday.
...Southwest...
Persistent westerly mid-level flow and developing lee-surface
troughing will promote dry and breezy conditions across eastern AZ
into central NM. While winds are fairly marginal compared to
previous days, widespread westerly winds of 15-20 mph and RH of less
than 15 percent amid dry fuels will support Elevated fire weather
conditions on Wednesday afternoon.
...Southern Georgia and northern Florida...
Beneath the upper level trough, a deepening surface low over the
Mid-Atlantic will enhance southwest to westerly surface winds across
much of the Southeast. An Elevated fire weather threat exists where
delayed Gulf moisture return amid an existing dry boundary layer is
expected to support minimum RH reductions of 25-35 percent (locally
less than 25 percent) across portions of southern GA into northern
FL by Wednesday afternoon. However, precipitation appears likely
along a southward progressing cold front through central GA. Fire
weather highlights may be adjusted in future outlooks as forecast
guidance aligns in the location/extent of the cold front and
rainfall amounts.

SPC Day 3-8 Fire Weather Outlook

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0440 PM CDT Tue Apr 28 2026
Valid 301200Z - 061200Z
...Synopsis...
An upper-level trough will be a predominant feature across the
eastern U.S. through early next week. A gradually southward
progressing cold front and accompanying rainfall is expected across
much of the Deep South, Southeast and portions of the Mid-Atlantic
where extensive drought and receptive fuels remain. This should have
an overall mitigating influence on fire weather concerns through the
weekend, with the exception of the FL Peninsula. Meanwhile, an
upper-level trough with accompanying ample Pacific moisture aloft
will intersect a cold front draped over the Southern Plains on Day
3-4/Thursday-Friday. This should support widespread wetting rains
and a reduced fire weather threat across much of the central and
southern High Plains. Upper-level ridging across the West will
promote a warming and drying trend through the weekend, with a dry
and breezy regime returning to the Desert Southwest and southern
Great Basin ahead of the next Pacific trough early next week.
...Day 3-5/Thursday-Saturday - Florida Peninsula...
Dry conditions including relative humidity at or below 35% and
breezy west winds are expected Days 3-4/Thursday-Friday with showers
and thunderstorms associated with a frontal boundary confined along
the northern Gulf Coast and the FL Panhandle. An upper-level wave
and deepening surface trough should bring increasing west/southwest
winds to FL on Day 5/Saturday. This could aid in bringing additional
boundary layer moisture from the Gulf into the state, although very
dry fuels and drought could still support wildfire spread. 40%
critical probabilities have been introduced into central FL for Days
3-5/Thursday-Saturday. Longer term forecast guidance shows
appreciable rainfall across the FL Peninsula on Day 6/Sunday as the
cold front finally shifts southeastward, bringing reprieve to a
preceding multi-day fire weather threat.
