SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1250 AM CST Tue Feb 25 2025
Valid 261200Z - 271200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms are possible from north Texas to the Ohio
Valley on Wednesday.
...Discussion...
A mid-level trough will amplify as it moves from the Upper Midwest
into the Lower Great Lakes and Ohio Valley on Wednesday. A surface
cold front will accompany this trough as it moves south through the
day. Moisture will be mostly limited, but there may be enough for
some weak instability from north Texas to the Ohio Valley. As
isentropic ascent and convergence along the cold front intensify,
isolated thunderstorms may develop during the afternoon. Any
thunderstorm activity should be mostly diurnally driven as elevated
instability will be minimal after sunset.

NWS Storm Prediction Center Norman OK
1127 PM CST Mon Feb 24 2025
Valid 251200Z - 261200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorm probabilities are less than 10 percent across the lower
48 States today.
...Discussion...
Strong upper trough is moving onshore along the Pacific Northwest
Coast early this morning. This feature will deamplify a bit as it
digs southeast across the northern Rockies into the central
Plains/upper MS Valley region by the end of the period. As this
short wave shifts inland, surface pressures will build over the
northern Rockies/Great Basin forcing a cold front into the eastern
Dakotas-central NE-central CO by 26/00z. Large-scale forcing ahead
of this feature will contribute to mid-level moistening within a
steep lapse rate environment. Forecast soundings along/near the
frontal zone suggest weak mid-level buoyancy, likely sufficient for
at least shallow elevated convection. While a few of the strongest
updrafts may penetrate levels necessary for lightning discharge,
current thinking is the probability for thunderstorms is too low to
warrant a risk this period.

MD 0119 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR NORTHERN OREGON...SOUTHERN WASHINGTON
Mesoscale Discussion 0119
NWS Storm Prediction Center Norman OK
0643 PM CST Mon Feb 24 2025
Areas affected...Northern Oregon...Southern Washington
Concerning...Severe potential...Watch unlikely
Valid 250043Z - 250245Z
Probability of Watch Issuance...5 percent
SUMMARY...Potential for a few gusts, some of which could be severe,
over the next few hours.
DISCUSSION...Thunderstorm activity is ongoing, with two more
organized bands noted near the Portland Metro and across the
Columbia Gorge. Though thermal profiles are poor, strong upper level
forcing from a mid-level jet max is overspreading the region amid
some MLCAPE around 100-240 J/kg. The increase in winds aloft can be
noted in the VAD from RTX (Portland, OR), where speeds up to 50-60
kts are observed in the bottom 3 km. A few gusts around 50 mph were
observed earlier in reporting sites near the Oregon coast. Steep low
to mid-level lapse rates are also in place regionally, with forecast
soundings from the NAM/RAP suggesting profiles are deeply mixed.
This will allow for potential for even low topped showers to mix
down higher momentum gusts at times, some of which may approach
severe limits. Given the rapid loss of daytime heating and poor
thermal environment, this is expected to remain localized and a
watch is unlikely to be needed.

Valid 250100Z - 251200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE PACIFIC NORTHWEST...AND OVER SOUTH FLORIDA...
...SUMMARY...
Scattered storms remain possible across the Florida Keys/far
southern Florida this evening. Localized damaging gusts or a brief
tornado may occur. Isolated strong wind gusts are also possible
across parts of the Pacific Northwest.
...01z Update...
Strong 12hr mid-level height falls are spreading across the Pacific
Northwest in response to a progressive trough that will advance
inland after 06z. 100+kt 500mb jet will translate across southern OR
and weaken late tonight as it shifts east with the short wave.
Scattered convection is currently noted ahead of the main jet core,
with lightning observed in the deeper updrafts, extending from off
the OR Coast into southwest WA. Isolated strong wind gusts have been
observed with this activity, and steep lapse rates appear somewhat
favorable for allowing strong flow just off the surface to mix down.
Have extended 5 percent severe wind probabilities to the WA/OR Coast
to account for this scenario, primarily this evening.
Low-latitude short-wave trough is digging southeast across the
central Gulf Basin. Low-level warm advection persists ahead of this
feature across south FL where a considerable amount of weak
convection is currently noted. Strong 0-6km bulk shear favors the
possibility for updraft organization, but poor lapse rates are
limiting buoyancy, and low-level shear is mostly weak. Will maintain
a MRGL Risk for the possibility of a wind gust or brief tornado.

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0308 PM CST Mon Feb 24 2025
Valid 261200Z - 041200Z
Fire weather concerns will remain limited through the middle portion
of the work week before increasing across the Southwest and southern
High Plains beginning on D5/Friday through early next week. The
general trend depicted in long-range guidance over the past several
days continues to hold with an upper-level regime change anticipated
heading into early March. Anomalously strong upper ridging over the
western CONUS will gradually break down through the end of the
current work week followed by a transition to a more progressive
regime characterized by higher-amplitude upper troughs meandering
across the Southwest and southern CONUS. As this occurs, robust
surface cyclogenesis will become more probable across the Four
Corners/Plains, resulting in strengthening winds over a region that
has seen little precipitation over the past 1-2 weeks and increasing
ERC values/fuel dryness. Elevated to critical fire weather
conditions appear possible each day from eastern AZ to western TX
beginning D5/Friday through D8/Tuesday, though confidence in the
potential on any given day remains somewhat low. While the GFS/ECMWF
both generally show the same evolution of the synoptic regime and
the potential for fire weather concerns, considerable discrepancies
regarding the timing and placement of upper-troughs and attendant
surface features are noted. Additionally, GEFS/ECENS guidance
appears to be too tightly clustered around their respective
deterministic solutions, leading to limited confidence that the most
probable scenario is being accurately captured by guidance at this
range. For this reason, highlights are withheld, but will likely be
needed in future forecast updates.
