SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook

Valid 081200Z - 091200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM EAST TEXAS
TO THE CENTRAL GULF COAST...
...SUMMARY...
Isolated to widely scattered strong to severe thunderstorms may
occur from portions of East Texas into the Central Gulf Coast region
on Saturday. Large hail is the primary hazard with the strongest
storms.
...Synopsis...
An upper-level trough will eject into the southern Plains during the
afternoon on Saturday. This feature will progress eastward into
parts of the lower Mississippi Valley late Saturday into Sunday
morning. A strong mid-level jet will accompany this trough. At the
surface, a cold front will be draped across the Mid-South/Southeast
into North Texas. A weak surface low will develop along the front in
Central/East Texas and move into lower Mississippi Valley during the
evening.
...North Texas...
Convection will likely be ongoing early Saturday morning. Forecast
soundings indicate sufficient elevated buoyancy, mid-level lapse
rates, and effective shear to support large hail for an hour or two.
Thereafter, buoyancy should quickly decrease.
...East Texas into lower Mississippi Valley and western Florida
Panhandle...
The cold front may make some southward progress early in the period,
but is generally expected to stall somewhere in the Gulf Coast
vicinity. This boundary will demarcate the where the greatest severe
potential will be as mid/upper 60s F dewpoints are expected south
of the boundary. While some convection may be ongoing along the
boundary early in the period, models suggest potential for
additional development by the evening as stronger mid-level ascent
approaches. Areas along and south of the cold front will have the
greatest potential for near-surface to surface based storms. Steep
mid-level lapse rates and strong deep-layer shear will support a
threat for large hail, primarily. Depending on the degree of
surface-based destabilization that occurs, and isolated strong wind
gusts or perhaps a tornado could also occur. Low-level wind fields
will not be overly strong, but should be sufficient for those
conditional risks.
The overall severe threat will gradually decrease with northern
extent. However, there will be some elevated buoyancy (perhaps
500-750 J/kg MUCAPE) north of the boundary along with strong
deep-layer shear. Small to marginally severe hail could occur with
the strongest storms.

...CRITICAL FIRE WEATHER AREA FOR THE TEXAS TRANS-PECOS AND FAR
SOUTHEASTERN NEW MEXICO...
The Elevated area was trimmed in the TX South Plains and TX
Panhandle, where recent rainfall and marginal wind/RH should limit
fire-weather concerns today. Farther northeast, an Elevated area was
added for portions of western OK into western north TX. Here, the
latest surface observations already show 15-20 mph sustained
northwesterly surface winds (with higher gusts) amid upper teens to
lower 20s RH. Given a lack of appreciable rainfall here over the
last several days, elevated fire-weather conditions are expected.
For additional details, see the previous discussion below.
..Weinman.. 03/07/2025
.PREV DISCUSSION... /ISSUED 0139 AM CST Fri Mar 07 2025/
...Synopsis...
A mid-level trough progressing across the Four Corners region, along
with a developing surface low over west-central Texas, will
translate eastward throughout today. Strong surface winds in the
vicinity of the surface low and immediately following a cold front
will bring Critical fire-weather conditions across much of West
Texas into Southeastern New Mexico. Elevated fire-weather conditions
will be present from southern and eastern New Mexico into portions
of the Texas Panhandle, down into the far western Edwards Plateau.
...West Texas into Far Southeastern New Mexico...
Across western Texas into far southeastern New Mexico, surface winds
are expected to reach as high as 30 MPH with relative humidity
values dropping into the single digits. The strongest surface winds
prior to the cold-frontal passage will be confined to the
U.S./Mexico border, particularly over the Texas Lowland Deserts,
Davis Mountains, and Big Bend, with a secondary round of
post-frontal high winds reaching further eastward and northward into
southern New Mexico. The post-frontal environment will be
characterized by higher relative humidity values at or above 20%,
but current ERC fuels guidance shows fuels at or above the 95th
annual and seasonal percentiles. Given the high winds and receptive
fuels, higher relative humidity values are not considered a limiting
factor for Critical conditions at this time.
...Eastern New Mexico into the Texas Panhandle...
Further north into the Texas Panhandle and eastern New Mexico,
Elevated fire-weather conditions are expected in both pre- and
post-frontal regimes, with winds around 15-20 MPH and relative
humidity values around 15%. Portions of the Oklahoma Panhandle into
eastern Oklahoma will also experience Elevated fire-weather
conditions, but recent wetting rainfall and current ERC fuels
guidance are limiting factors for the inclusion of highlights.

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1100 AM CST Fri Mar 07 2025
Valid 071700Z - 081200Z
...CRITICAL FIRE WEATHER AREA FOR THE TEXAS TRANS-PECOS AND FAR
SOUTHEASTERN NEW MEXICO...
The Elevated area was trimmed in the TX South Plains and TX
Panhandle, where recent rainfall and marginal wind/RH should limit
fire-weather concerns today. Farther northeast, an Elevated area was
added for portions of western OK into western north TX. Here, the
latest surface observations already show 15-20 mph sustained
northwesterly surface winds (with higher gusts) amid upper teens to
lower 20s RH. Given a lack of appreciable rainfall here over the
last several days, elevated fire-weather conditions are expected.
For additional details, see the previous discussion below.
..Weinman.. 03/07/2025
.PREV DISCUSSION... /ISSUED 0139 AM CST Fri Mar 07 2025/
...Synopsis...
A mid-level trough progressing across the Four Corners region, along
with a developing surface low over west-central Texas, will
translate eastward throughout today. Strong surface winds in the
vicinity of the surface low and immediately following a cold front
will bring Critical fire-weather conditions across much of West
Texas into Southeastern New Mexico. Elevated fire-weather conditions
will be present from southern and eastern New Mexico into portions
of the Texas Panhandle, down into the far western Edwards Plateau.
...West Texas into Far Southeastern New Mexico...
Across western Texas into far southeastern New Mexico, surface winds
are expected to reach as high as 30 MPH with relative humidity
values dropping into the single digits. The strongest surface winds
prior to the cold-frontal passage will be confined to the
U.S./Mexico border, particularly over the Texas Lowland Deserts,
Davis Mountains, and Big Bend, with a secondary round of
post-frontal high winds reaching further eastward and northward into
southern New Mexico. The post-frontal environment will be
characterized by higher relative humidity values at or above 20%,
but current ERC fuels guidance shows fuels at or above the 95th
annual and seasonal percentiles. Given the high winds and receptive
fuels, higher relative humidity values are not considered a limiting
factor for Critical conditions at this time.
...Eastern New Mexico into the Texas Panhandle...
Further north into the Texas Panhandle and eastern New Mexico,
Elevated fire-weather conditions are expected in both pre- and
post-frontal regimes, with winds around 15-20 MPH and relative
humidity values around 15%. Portions of the Oklahoma Panhandle into
eastern Oklahoma will also experience Elevated fire-weather
conditions, but recent wetting rainfall and current ERC fuels
guidance are limiting factors for the inclusion of highlights.

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1030 AM CST Fri Mar 07 2025
Valid 071630Z - 081200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS NORTHWEST
TEXAS/TEXAS BIG COUNTRY LATE TONIGHT INTO EARLY TOMORROW MORNING...
...SUMMARY...
Thunderstorms capable of producing isolated hail are possible across
northwest Texas/Texas Big Country late tonight into early tomorrow
morning. Additional thunderstorms are possible across the Southwest
States this afternoon and evening.
...Northwest TX/TX Big Country...
Recent satellite imagery shows a well-defined upper low over the
Lower CO Valley. This upper low is forecast to progress eastward
across the Southwest States, with an expansive fetch of
southwesterly flow aloft extending from the base of this low into
the OH Valley. Recent satellite imagery also shows a low-amplitude
shortwave trough over the central Plains, while the 15Z surface
analysis places an associated low over the MCI vicinity. A cold
front extends back west-southwestward from this low into the OK
Panhandle while a dryline extends more southwestward through central
OK into southwest TX.
The central Plains shortwave is expected to progress quickly
northeastward through the OH Valley, with the attendant surface low
taking a similar path while gradually weakening/filling. The cold
front will push southward through OK into north TX, gradually
slowing its progress throughout the evening as surface pressures
fall across the southern High Plains ahead of the approaching
Southwest upper low. A modest surface low will likely develop along
the southwestern periphery of the cold front (over the southwest
TX/western TX Hill Country vicinity) early tomorrow morning.
Low/mid-level southern flow will strengthen as this low develops,
creating a region of focused warm-air advection over the TX Big
Country/northwest TX. Resultant moistening of low levels (around 850
mb) beneath profiles characterized by cold mid-level temperatures
and steep mid-level lapse rates will likely result in around 1000
J/kg of MUCAPE from 08/09Z through 12Z. This buoyancy coupled with
continued forcing for ascent, from both warm-air advection and the
approaching upper low, will support thunderstorm development. Strong
southwesterly flow will exist through the cloud-bearing layer, and
the resulting shear is expected to be strong enough to support
organized storms capable of producing hail. This threat will be
fairly localized and only last a few hours, but the anticipated
strong/severe storm coverage merits the introduction of 5% hail
probabilities.
...Elsewhere...
Isolated thunderstorms are anticipated this afternoon across the
Southwest, as ascent from an upper low traverse the region interacts
with limited buoyancy supported by steep lapse rates and modest
low/mid-level moisture. Highest coverage is anticipated over
northwest/north-central NM this afternoon and evening. A few
thunderstorms are possible along the central Gulf Coast early
tomorrow morning as well.
Additionally, a few lightning flashes are possible within any of the
deeper convective cores across southern CA this afternoon/evening.
Even so, overall coverage is currently expected to be less than 10%.
