...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE NORTHERN PLAINS...
...Synopsis...
A mid-level impulse will traverse the north-central CONUS today,
encouraging surface troughing across the northern Plains into the
southern High Plains, with a surface cold front poised to surge
southward across the northern Plains during the later half of the
period. Preceding the surface cold front, within the surface
troughing regime, dry and windy conditions are expected across
portions of the northern and central Plains. Over the central
Plains, 15-25 mph west-southwesterly sustained surface winds amid
15-20 percent RH will encourage Elevated wildfire-spread potential
given dry fuels. Across the northern Plains, closer to the stronger
upper support, sustained westerly surface winds may reach 20 mph in
spots, with sustained northwesterly surface winds potentially
exceeding 30 mph behind the cold front. Given dry fine fuels and RH
dipping to at least the 15-25 percent range by afternoon peak
heating, Elevated/Critical highlights have been maintained.

...CRITICAL FIRE WEATHER AREA FOR EXTREME SOUTHEAST ARIZONA INTO
CENTRAL AND SOUTHERN NEW MEXICO...
...Synopsis...
A mid-level trough over the eastern Pacific will rapidly approach
the CONUS and impinge on the Desert Southwest tomorrow (Tuesday),
encouraging surface low development across the southern Plains. As
this occurs, dry downslope flow from the southern Rockies will
overspread portions of the southern High Plains, promoting
wildfire-spread potential. By afternoon peak heating,
west-southwesterly surface winds in the 15-25 mph range will become
common, along with RH dipping to 5-15 percent. Critical fire weather
highlights have been introduced where guidance consensus shows 20+
mph sustained surface winds overlapping with 10 percent RH for at
least a few hours Tuesday afternoon.

Day 3-8 Fire Weather Outlook

0412 PM CDT Sun Mar 09 2025
Valid 111200Z - 171200Z
A very active fire-weather pattern is expected across the southern
Plains throughout the extended forecast period, as a series of
robust midlevel shortwave troughs traverse the area amid
increasingly dry/receptive fuels. The greatest concern is on Day
6/Friday, when widespread critical conditions are expected across
the southern Plains, with the potential for high-end critical to
extremely critical conditions also evident.
...Days 3-5/Tuesday-Thursday - Southern High Plains...
The first low-latitude midlevel shortwave trough and related strong
flow aloft will overspread the southern Rockies and adjacent High
Plains during this time frame. This will yield dry/windy conditions
west of the dryline each afternoon, with critical conditions
expected.
...Day 6/Friday - Southern Plains...
A highly amplified large-scale trough and attendant 100+ kt midlevel
jet streak will emerge over the southern Plains, while a surface
cyclone rapidly deepens over the central Plains. In response, very
strong deep-layer westerly flow will overspread a deep/dry air mass
across the southern Plains, where fuels will be drying out leading
up to the event. This system will favor widespread critical to
extremely critical fire-weather conditions. Further northeastward
extensions of the 70-percent Critical probabilities may become
necessary in future outlooks as forecast confidence increases
regrading RH reductions.
Thereafter, a secondary low-latitude shortwave trough will likely
emerge over the southern High Plains on Day 7/Saturday, leading to
another day of critical conditions across the region.
