SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0242 PM CDT Wed Mar 20 2024
Valid 202000Z - 211200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS NORTHWEST
TEXAS INTO WESTERN OKLAHOMA...AND ACROSS THE TEXAS COAST...
...SUMMARY...
Isolated, marginally severe storms will be possible through this
evening across parts of western Oklahoma and northwest Texas. Hail
will be possible early Thursday morning across the Texas Coastal
Plain vicinity.
...20z Update...
The only changes with the 20z update were to adjust 10 percent
thunderstorm probabilities based on ongoing convection and trends in
short term guidance. The Marginal (level 1 of 5) risks across TX and
OK remain unchanged from the previous outlook. Isolated large hail
will be the main risk, though strong gusts also are possible with
storms across the northwest TX into western OK. See previous
discussion below for more details.
..Leitman.. 03/20/2024
.PREV DISCUSSION... /ISSUED 1133 AM CDT Wed Mar 20 2024/
...Parts of western and central Oklahoma and adjacent portions of
Texas...
Rather steep mid-level lapse rates across the Oklahoma/Texas area
are contributing to isolated/high-based convection across central
Oklahoma late this morning. Daytime heating of a very modestly
moist boundary layer will push mixed-layer CAPE values up to 500
J/kg mixed-layer CAPE locally across portions of the Texas
Panhandle/northwestern Texas and into western and central Oklahoma
this afternoon. This will be sufficient -- given modest ascent in
the vicinity of weak surface low pressure over northern Oklahoma and
associated surface troughing extending southwestward -- to permit
additional/new storm development this afternoon.
With a rather deep mixed-layer evolving through peak heating, a few
strong wind gusts could occur near more intense convection.
Marginal hail also cannot be ruled out, given ample shear and the
steep mid-level lapse rates. Overall risk will remain limited and
isolated.
...Middle Texas Coast vicinity...
Low-level warm advection/quasi-geostrophic ascent will increase
across eastern Texas tonight, as short-wave troughing shifts into
the southern Plains from northern Mexico. Atop a low-level stable
layer, steep mid-level lapse rates may support development of
isolated thunderstorms very late in the period, in response to the
increasing ascent. With ample cloud-layer shear for sustained
updrafts, some risk for hail may evolve toward the end of the
period, with a couple of the strongest storms -- largely in the inch
to inch-and-a-half range.
...Elsewhere...
Very weak convection is ongoing across the Northeast, as strong
upper troughing shifts across the region. Convection will remain
very low-topped and likely with little to no lightning given lack of
appreciable CAPE. However, very strong deep-layer flow across the
region will likely promote gusty winds, and associated tree damage
this afternoon/evening.

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0154 PM CDT Wed Mar 20 2024
Valid 211200Z - 221200Z
An Elevated risk area is introduced to portions of southeast Wyoming
into adjacent areas of western Nebraska. Latest forecast guidance
continues to show the development of a strong downslope flow regime
across central WY to the NE Panhandle. Spread in guidance has been
sufficiently reduced to introduce a fire weather risk area. While
ERCs remain somewhat marginal for much of the region, local reports
suggest that fine, 1-hour fuels should be sufficiently dry to
support a fire threat. 15-25 mph winds with 20-25% RH remains likely
across this region, but drier/windier solutions hint at RH
reductions down to 15% by peak heating.
..Moore.. 03/20/2024
.PREV DISCUSSION... /ISSUED 0154 AM CDT Wed Mar 20 2024/
...Synopsis...
Predominantly zonal mid-level flow is anticipated across the U.S. on
Thursday, leading to generally mild conditions and low fire-weather
concerns. Locally drier and windier conditions could develop in
portions of the Southern and Central Plains, but confidence is
currently too low in these scenarios to warrant any Elevated areas
at this time.
...NE Panhandle and vicinity...
Confidence has increased in a surface cyclone developing in the lee
of the Rockies near the NE Panhandle throughout the day on Thursday.
This will support some moisture return across the Southern Plains,
as well as relatively dry, downsloping flow in the NE Panhandle,
eastern WY, and northeastern CO. Deep, well-mixed boundary layers
could yield relative humidities around 20 percent across the region
with sustained winds of 15-20 mph. Fuels do not appear to be
critically dry, but could support some fire spread (e.g., ERCs
approaching the 70-80th percentiles in some areas). No Elevated area
is delineated in this outlook due to slightly lower confidence in
the location of the surface cyclone and attendant moisture
gradients; guidance will be monitored for possible future inclusion.
...West TX...
An area of slightly stronger mid-level flow is expected to
overspread West TX on Thursday afternoon, contributing to locally
gustier surface conditions. Wind speeds around 15-20 mph and
relative humidities around 15-20 percent could contribute to local
Elevated fire-weather conditions. However, highlighting a particular
area is currently difficult due to the chance for wetting
precipitation Wednesday night into Thursday morning. Confidence in
such a scenario will continue to be monitored, possibly warranting
areal delineations in future outlooks.

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0154 PM CDT Wed Mar 20 2024
Valid 211200Z - 221200Z
An Elevated risk area is introduced to portions of southeast Wyoming
into adjacent areas of western Nebraska. Latest forecast guidance
continues to show the development of a strong downslope flow regime
across central WY to the NE Panhandle. Spread in guidance has been
sufficiently reduced to introduce a fire weather risk area. While
ERCs remain somewhat marginal for much of the region, local reports
suggest that fine, 1-hour fuels should be sufficiently dry to
support a fire threat. 15-25 mph winds with 20-25% RH remains likely
across this region, but drier/windier solutions hint at RH
reductions down to 15% by peak heating.
..Moore.. 03/20/2024
.PREV DISCUSSION... /ISSUED 0154 AM CDT Wed Mar 20 2024/
...Synopsis...
Predominantly zonal mid-level flow is anticipated across the U.S. on
Thursday, leading to generally mild conditions and low fire-weather
concerns. Locally drier and windier conditions could develop in
portions of the Southern and Central Plains, but confidence is
currently too low in these scenarios to warrant any Elevated areas
at this time.
...NE Panhandle and vicinity...
Confidence has increased in a surface cyclone developing in the lee
of the Rockies near the NE Panhandle throughout the day on Thursday.
This will support some moisture return across the Southern Plains,
as well as relatively dry, downsloping flow in the NE Panhandle,
eastern WY, and northeastern CO. Deep, well-mixed boundary layers
could yield relative humidities around 20 percent across the region
with sustained winds of 15-20 mph. Fuels do not appear to be
critically dry, but could support some fire spread (e.g., ERCs
approaching the 70-80th percentiles in some areas). No Elevated area
is delineated in this outlook due to slightly lower confidence in
the location of the surface cyclone and attendant moisture
