Areas affected...Central into southern Lower Michigan
Concerning...Tornado Watch 113...
Valid 150223Z - 150400Z
The severe weather threat for Tornado Watch 113 continues.
SUMMARY...Aside from damaging winds and isolated large hail,
discrete storms near the warm front will pose the greatest tornado
risk if they can intensify.
DISCUSSION...Discrete convection has been noted ahead of the linear
segments moving southeastward off of Lake Michigan. Given their
proximity to the warm front and the large SRH on KGRR VAD (over 400
0-1 km), these storms will pose the greatest risk for tornadoes
should they intensify. A strong tornado is possible within this
environment.

0832 PM CDT Tue Apr 14 2026
Areas affected...Northern Illinois and southeast Wisconsin
Concerning...Tornado Watch 109...
Valid 150132Z - 150300Z
The severe weather threat for Tornado Watch 109 continues.
SUMMARY...The tornado risk will focus on northern Illinois with QLCS
circulations still possible farther north. Damaging wind potential
will be greatest with linear storm modes.
DISCUSSION...The strongest activity in WW 109 exists in northern
Illinois. With the low-level jet focusing in this area (50+ kts
noted on KDVN and KLOT VAD), moist inflow and strong low-level shear
will support a threat for tornadoes (possibly strong) as well as
damaging winds and isolated large hail. Storm interactions have thus
far limited how organized low-level mesocyclones have become, but
the environment is quite favorable.
In southeast Wisconsin, convection has been much more linear. A line
segment moving toward Milwaukee is favorably oriented with the deep
layer shear vector. Damaging winds are still possible, but the
impacts of earlier supercell outflow may modulate this threat to
some extent. The KMKX VAD still shows sufficient low-level shear
that QLCS circulations may also occur at the leading edge of the
convective line.

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0754 PM CDT Tue Apr 14 2026
Valid 150100Z - 151200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROS PORTIONS
OF THE GREAT LAKES REGION...
...SUMMARY...
Severe thunderstorms are expected through tonight from the southern
Plains into the Midwest. Large hail, several tornadoes (some
strong), and swaths of severe/damaging gusts are all likely,
particularly from eastern Iowa into the southern Great Lakes.
...Synopsis...
Scattered discrete/semi-discrete supercells are ongoing across
eastern Iowa, far northern Illinois, and southern Wisconsin along a
diffuse warm frontal zone stretching eastward from weak surface low
analyzed over eastern NE/western IA. The primary severe risk through
the overnight hours will be associated with this activity as it
spreads southeast through early morning. Further south across the
central/southern Plains, poorly organized convection casts
uncertainty in the nocturnal severe threat; however, a favorable
environment will remain in place through Wednesday morning and could
support severe convection.
...Midwest/Great Lakes...
01 UTC regional radar mosaics show semi-discrete supercells ongoing
across far eastern IA, northern IL, and southern WI with the early
stages of upscale growth evident as storms interactions increase.
This trend will continue through the overnight hours as this
activity propagates east/southeast into lower MI and northern IN.
The recent 00z DVN RAOB sampled a convective environment highly
favorable for organized convection, which will maintain the
potential for significant hail and tornadoes in the near term (most
likely through 03 UTC) before a full transition to a linear mode
takes place. Once this transition occurs, severe winds (including
the potential for significant gusts in excess of 75 mph) and
embedded circulations appear probable for areas downstream.
...Southern Iowa into Kansas...
Thunderstorm development along a southward sagging cold front is
anticipated in the coming hours across northeast KS into southern
IA. Regional soundings sampled adequate buoyancy and strong
deep-layer wind shear (around 50 knots) that will likely support
organized convection along the front for a few hours. Storm motions
along the boundary may foster clustering/upscale growth, but a
severe wind, hail, and perhaps tornado threat is expected to
materialize through the night.
...Oklahoma into Texas...
Convective evolution thus far across western OK into northwest TX
has been relatively lackluster given the otherwise buoyant and
strongly sheared environment sampled by the 00z OUN sounding. This
is likely due to expansive convective outflows resulting in
undercutting and clustered storm modes as well as the presence of a
subsidence inversion (also noted in the 00z sounding). It remains
unclear whether or not this activity will be able to re-intensify
through the late evening hours given. However, strengthening flow
fields through 06 UTC may support some degree of improved
organization and a more robust severe threat. This potential is
hinted by recent HRRR solutions, but overall confidence is limited.
Based on these trends, opted to remove the 30% hail/wind
probabilities given low confidence in severe coverage. Further south
into western TX, attempts at sustained convection have been noted
over the past hour along the dryline, but downstream inhibition may
limit overall storm coverage.

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0504 PM CDT Tue Apr 14 2026
Valid 161200Z - 221200Z
...Synopsis...
A pronounced upper trough moves into the Pacific Northwest Day
3/Thursday. Increasing southwesterly flow aloft ahead of the
eastward propagating trough should promote dry, downslope flow and a
continued fire weather threat across the southern High Plains on Day
3/Thursday. A more widespread fire weather threat is expected on Day
4/Friday as the amplifying trough moves into the central U.S.
Farther east, upper-level ridging will keep much of the Mid Atlantic
and Southeastern U.S. dry through the week. The exceptionally dry
fuels and occasional elevated southerly winds will pose a lingering
fire weather threat across this region. Towards the end of the
forecast period, another deep trough will approach western CONUS.
While extended model discrepancy exists, fire weather concerns will
likely continue next week in regions that have seen minimal
precipitation.
...Portions of the Central/Southern Plains - Day 3/Thursday through
Day 6/Sunday...
On Day 3/Thursday, southwesterly flow aloft and subsequent lee
surface troughing will support a continued fire weather threat as
dry and breezy southwesterly surface flow extends into the
upper-central High Plains. Southwesterly winds of 15-25 mph combined
with RH hovering around 15 percent are expected across portions of
the southern Plains, with 40% probabilities of Critical fire weather
conditions maintained. North of a region of forecast precipitation
on Day 1/Tuesday - Day 2/Wednesday, 40% Critical probabilities have
been introduced across eastern WY, southern SD, and northern NE.
This is to account for 15-25 percent RH and southwesterly winds of
15-20 mph atop drying fuels. However, increasing mid/high level
clouds may dampen the bimodal fire environment to some extent,
precluding the introduction of 70% Critical probabilities at this
time.
A more pronounced and amplified upper-level trough approaches the
central CONUS by Day 4/Friday. The associated mid-level jet streak
and deepening surface cyclone across the central Plains will aid in
stronger west/southwest winds behind the persistent dry line. 70%
Critical probabilities have been maintained for Day 4/Friday across
much of east/southeastern NM, TX/OK Panhandles, and parts of West
Texas where extended guidance agreement portrays combined
probabilities of less than 15 percent RH and greater than 20 mph
winds, and the potential for an incoming cold front that may further
exacerbate the fire environment.
On Day 5/Saturday, locally elevated fire weather conditions may
arise in a dry post-frontal airmass, though uncertainty in frontal
timing and overlap of stronger winds and lower RH precludes the
introduction of probabilities at this time. As the amplified upper
trough exits the region on Day 6/Sunday, surface troughing across
High Plains and surface high pressure centered over east TX will
promote dry return flow for much of the region. Given the overall
pattern and ensemble guidance agreement in low RH and stronger
winds, 40% Critical probabilities have been introduced.
...Mid-Atlantic/Piedmont - Day 3/Thursday through Day 6/Sunday...
On Day 3/Thursday, a leading shortwave will aid in the breakdown of
the upper ridge across the East Coast. However, precipitation
chances are minimal east of the Blue Ridge Mountains, maintaining
dry conditions. Southwesterly winds of up to 10 mph and 25-35
percent RH atop receptive fuels support the introduction of 40%
Critical probabilities across the region. As the East Coast upper
ridge breaks down ahead of the deepening upper trough over the High
Plains on Day 4/Friday, the potential for a downslope wind event
exists in the lee of the Appalachians. Strong west/northwesterly
winds will traverse the Blue Ridge Mountains allowing for surface RH
to drop as surface winds increase along the Piedmont, promoting the
introduction of 40% Critical probabilities. On Day 5/Saturday, dry
southwesterly flow returns to the Piedmont and broader Southeast as
the surface low enters southern Ontario. With no expected
precipitation across the region, 40% Critical probabilities have
been introduced where dry and breezy conditions continue atop dry
fuels. Chances for precipitation increase on Day 6/Sunday as the
upper trough moves overhead, which could alleviate broader fire
concerns. However, the extent of wetting rainfall is uncertain,
precluding the introduction of probabilities at this time.
