Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0148 AM CDT Fri Mar 13 2026
Valid 131200Z - 141200Z
...Synopsis...
Dry and breezy downslope winds will be likely across portions of the
southern High Plains today. Overlap of relative humidity around
10-15% with sustained west-northwesterly winds around 10-15 mph and
receptive fuels will support a broad area of Elevated fire concerns
in the lee of the higher terrain from eastern Wyoming to New Mexico
and east in NE, KS, OK Panhandle. A few more favored downslope
locations in the immediate lee of the terrain across central New
Mexico and south-central Colorado will see locally Critical
conditions at times. For now, this area remains too localized for
inclusion of Critical areas.

...CRITICAL FIRE WEATHER AREA FOR CENTRAL/EASTERN NEW MEXICO AND
PORTIONS OF WEST TEXAS...
...Synopsis...
A shortwave trough will move southward across the Pacific Northwest
into the Northern Rockies on D2/Saturday. As westerly flow develops
across the Rockies, strong lee cyclone development is likely on
D2/Saturday across the Nebraska Panhandle. As a result, westerly
surface gradients will strengthen across the central/southern High
Plains. Very strong/dry downslope flow is expected to develop,
particularly across eastern New Mexico into far western Texas. In
this region, sustained westerly surface winds 15-20 mph will overlap
relative humidity reductions to 10-15 percent. This in combination
with dry fuels will support maintaining Critical fire areas for
Saturday. Broader Elevated fire weather concerns are expected to
extend into eastern Colorado and far southeastern Wyoming/western
Nebraska. The immediate area in the lee of the higher terrain in
eastern Colorado may see locally Critical conditions. This area may
need to be included in further outlooks if trends increase or
confidence in mountain wave activity increases. Elevated to locally
critical fire weather conditions are likely to persist overnight on
portions of the southern and central High Plains.
Elevated to critical meteorological conditions will extend into
portions of western New Mexico and Arizona. For now, fuels in this
region are not supportive but this event will work to precondition
fuels amid temperatures well above normal.

Day 3-8 Fire Weather Outlook

Valid 141200Z - 201200Z
Progressive zonal flow continues across the central CONUS this
weekend transitioning into a more high-amplitude pattern early next
week and persisting through the forecast period. On Day 4/Sunday, an
upper level trough will dig aggressively southward into the central
and southern Rocky Mountains. This trough tracks through the
southern Appalachians by the end of Day 5/Monday before moving
toward the northeast CONUS on Day 6/Tuesday. Recent forecast
guidance continues to exhibit a notable southern trend and slower
eastward progression with this trough's evolution, introducing some
uncertainty regarding the exact timing of the peak wind as it shifts
eastward. Simultaneously, a robust upper-level ridge will amplify
over the western CONUS. By mid-to-late week, this ridge is forecast
to center over Arizona, with near-record heights over much of the
Southwest.
On Day 3/Saturday, the latest guidance continues to favor robust
surface winds over the southern and central Rockies, extending into
the adjacent High Plains. This area will continue to be watched
closely for a potential mountain wave that would enhance lee side
winds. The limiting factor keeping the outlook area from being drawn
farther west is the higher fuel moisture in place across extreme
western New Mexico into Arizona and Utah where wind and RHs are
expected to meet criteria. However, this event will serve to
pre-condition fuels in these areas as surface temperatures remain
nearly 20 degrees above normal throughout much of the central and
southern High Plains. Additionally, elevated to locally critical
fire weather conditions are likely to persist overnight on portions
of the southern and central High Plains.
On Day 4/Sunday, as the trough axis shifts, vigorous northwest flow
on the backside of the system will maintain a corridor of strong
winds and persistent dry air across SE New Mexico and West Texas.
Both of the 40% and 70% probabilities areas were expanded to account
for the stronger upper-level jet max overhead and the tightening
surface pressure gradient ahead of the advancing cold front.
Conversely, the central and northern Plains will see a transition to
much more stable, post-frontal conditions with significantly cooler
temperatures, keeping these regions below critical thresholds.
On Day 5/Monday, expect breezy and dry conditions to persist across
eastern New Mexico under northerly flow. While the airmass remains
dry, surface temperatures will be cooler and surface wind speeds
appear more localized and marginal. While locally elevated
conditions will be possible, the lack of a widespread, tightened
surface pressure gradient suggests a lower probability of a critical
area at this lead time. An area of 40% probability was added over
extreme south Texas where northerly winds will combine with dry air
behind the front.
On Day 6/Tuesday, warmer temperatures return to the High Plains with
north to northwest upper level flow above much of the central CONUS.
With warmer surface temperatures and resultant higher surface
mixing, more widespread critical conditions will be possible over
portions of the southern Plains. Additionally, the post-frontal
environment over Georgia and Florida, where fuels are driest, will
provide opportunity for locally elevated conditions.
Well above normal temperatures and dry conditions will continue to
cure fuels over the course of several consecutive days across the
southern half of the western CONUS through the outlook period.
Regardless of winds, temperatures and RHs would suggest extended
burn periods across these areas given receptive fuels.
