SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0153 PM CST Sun Feb 25 2024
Valid 261200Z - 271200Z
...CRITICAL FIRE WEATHER AREA FOR PARTS OF EASTERN NEW MEXICO INTO
THE TEXAS PANHANDLE AND SOUTH PLAINS...
The Elevated area has been expanded into more of the central Plains
and Midwest. Surface winds should reach 15-20 mph ahead of the
surface front with RH likely falling to around 20-25% (locally
lower, particularly with westward extent). Elsewhere, only minor
modifications were made based on the most recent guidance.
..Wendt.. 02/25/2024
.PREV DISCUSSION... /ISSUED 0159 AM CST Sun Feb 25 2024/
...Synopsis...
Split mid-level flow over the western and central US will gradually
coalesce into broad and strong southwesterly flow as a Pacific
trough digs south over the northern Great Basin. Several weak
perturbations within the amplified sub-tropical jet will move across
the southern and central Rockies intensifying a robust surface lee
trough. Increasing downslope pressure gradients and momentum
transfer from the flow aloft will bolster strong surface winds
across the southern and central High Plains. With unusually warm and
dry conditions also present, widespread elevated and critical
fire-weather conditions are expected over the southern High Plains.
...Southern and central High Plains...
As flow aloft strengthens and gradually becomes southwesterly, lee
troughing should rapidly intensify across the southern and central
High Plains. Downslope winds of 25-30 mph appear likely Monday
afternoon across parts of eastern NM, southeastern CO and western
TX/OK. Coincident with temperatures in the 70s to 80s F, afternoon
RH values will fall to 15-20%. Intensifying dryness in area fuels
is expected to support the risk for fire spread in combination with
the aforementioned meteorological conditions. Widespread elevated to
critical fire-weather concerns appear likely for the southern and
central High Plains. Localized fire-weather concerns are also
possible farther north into parts of eastern WY and western NE,
though fuels here are less receptive and uncertainty is higher.

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1116 AM CST Sun Feb 25 2024
Valid 261200Z - 271200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected on Monday.
...Synopsis...
The upper-air pattern on Monday will feature a split-flow regime
over the West. A mid-level trough over the Pacific Northwest coast
will amplify as it moves southeastward into the northern
Rockies/northern Intermountain regions. A belt of strong
subtropical flow will extend from the eastern Pacific
east-northeastward into the Desert Southwest/south-central U.S. In
the low levels, a surface low over the Upper Midwest will shift
southeast, as a cold front pushes through the northern Rockies and
the northern Great Plains. A warm conveyor belt farther east over
the mid MS Valley will likely lead to isolated to widely scattered
showers and a few thunderstorms developing within a broad zone of
warm-air advection from the Mid South northward into the southern
Great Lakes. Current indications by model guidance suggest only low
thunderstorm probabilities across the southern Great Lakes Monday
night, lending doubt to the need for low-severe probabilities.

this morning as well as updated fuel information.
..Wendt.. 02/25/2024
.PREV DISCUSSION... /ISSUED 0158 AM CST Sun Feb 25 2024/
...Synopsis...
Split flow aloft will continue to strengthen over much of the
western and central US before turning more zonal with time. Several
small perturbations within the southern branch of the strong flow
will cross the southern Rockies strengthening a lee trough.
Downslope winds across parts of the southern High Plains will likely
support elevated to near-critical fire-weather conditions.
...Southwest and Southern High Plains...
Northwest flow aloft is forecast to intensify over parts of the
Southwest and southern High Plains through D2/Sunday. Aided by the
stronger flow aloft, and a lee trough, gusty downslope winds of
20-25 mph are possible across parts of eastern NM, southeastern CO
and west TX. Afternoon RH values below 20% will also be likely with
unseasonably warm temperatures. With little rain over this area in
the past several weeks, emerging dryness within area fuels is
expected to support a risk for elevated to near-critical
fire-weather conditions through the afternoon hours.
Strong winds and low humidity may also extend farther north across
parts of eastern CO and southeastern WY where strong gusts are
expected through terrain gaps. While meteorological conditions
appear likely to support some risk for critical fire-weather
conditions, area fuels remain only modestly receptive. Uncertainty
on fuel availability is high suggesting concerns will likely remain
more localized.

A split-flow pattern is present across the CONUS today with surface
high pressure and a dry air mass in place across most of the country
except for the Northwest.
A mid-level trough will amplify across the Pacific Northwest through
the period which will bring significant rain and mountain snow. As
cold air overspreads the region tonight, enough destabilization may
occur to support some lightning strikes with cellular convection
across the ocean, but perhaps also inland across western Washington.
Elsewhere, no thunderstorms are anticipated.

Isolated thunderstorms may occur Sunday night across parts of
coastal/northwest Washington.
...Discussion...
The upper flow field across the U.S. will continue to trend toward
an increasingly zonal configuration with time, as upper troughing
continues to shift away from the East Coast into the western
Atlantic.
At the surface, high pressure will prevail across much of the
country, along with generally dry/stable conditions.
During the second half of the period, a short-wave trough digging
southward along the British Columbia coast will reach the Pacific
Northwest. Cold air aloft/steep lapse rates will likely yield weak
destabilization late -- largely across the western Washington
vicinity. As such, sporadic lighting may evolve with showery
convection anticipated across this area.
Elsewhere, thunderstorms are not expected.
