Day 1 Fire Weather Outlook

1246 AM CDT Mon Apr 13 2026
Valid 131200Z - 141200Z
...CRITICAL FIRE WEATHER AREA FOR EASTERN WYOMING...SOUTHWESTERN
SOUTH DAKOTA...NORTHWESTERN NEBRASKA...
...CRITICAL FIRE WEATHER AREA FOR SOUTHEASTERN COLORADO AND ADJACENT
HIGH PLAINS...
...Synopsis...
Continued southwesterly flow aloft is expected today across much of
the central/southern Plains. A shortwave trough is expected to
approach the southern Plains very late in the period. A weaker
shortwave trough in the central Northern Plains will also be
present. At the surface, a broad area of low pressure will exist
east of the terrain.
...Eastern Wyoming into western South Dakota and Nebraska...
The northern stream mid-level jet will be favorably timed with
afternoon heating/minimum RH. This feature, coupled with the surface
trough to the east, will drive 20-25 mph winds in eastern portions
of Wyoming and adjacent western South Dakota and Nebraska. RH will
likely fall to 10-15%. Critical fire weather is expected for a few
hours during the afternoon. Farther south into the Front Range,
winds will be weaker leading to elevated fire weather.
...Southeast Colorado and vicinity...
The position of a modest surface low in southeast Colorado will
promote surface winds of around 20 mph despite the stronger
mid-level winds lagging farther southwest. Terrain enhancement could
also lead to local corridors of stronger winds. RH of around 15% is
expected during the afternoon. These conditions will support
critical fire weather.
...Piedmont...southern Appalachians...
Dry return flow around a surface high pressure system will promote
10-15 mph winds within parts of the southern Appalachians and the
Piedmont region. RH of near 20% is possible in parts of the
Mid-Atlantic though higher values of 25-35% are expected with
southward extent. Given how dry fuels are, elevated fire weather
conditions are expected.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1248 AM CDT Mon Apr 13 2026
Valid 141200Z - 151200Z
...CRITICAL FIRE WEATHER AREA FOR SOUTHEAST COLORADO AND ADJACENT
HIGH PLAINS...
...Synopsis...
The progression of the upper trough in the Southwest/southern High
Plains is expected to slow on Tuesday. The trough may not eject into
the Plains until early Wednesday morning. A surface low will deepen
in the central High Plains.
...Southeast Colorado and vicinity...
A similar setup to Monday is expected, though the location of the
trough will bring better alignment of stronger mid-level winds to
the region. The deepening surface low will further increase surface
wind speeds to 20-25 mph. RH of around 15% appears likely. Farther
east into Kansas, the surface winds will be similarly strong along
with a very dry airmass (RH perhaps nearing 10% in some locations).
Recent rainfall should mitigate some fire weather risk with eastward
extent. Critical fire weather is expected.
...Parts of the Southwest into the southern High Plains...
The base of the trough over this region along with a moderately
strong surface pressure gradient will promote 15-20 mph winds. RH
will be somewhat uncertain given the expected mid-level clouds.
However, around 20% is possible for broad portions of the region.
Elevated fire weather is forecast during the afternoon.
...Mid-Atlantic...
Dry return flow will continue in the Mid-Atlantic. 10-15 mph winds
around the surface high are probable during the afternoon. 25-30% RH
will also occur. Despite the marginal meteorological conditions,
very dry fuels will support an elevated fire weather threat.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0436 PM CDT Sun Apr 12 2026
Valid 141200Z - 201200Z
...Synopsis...
A robust mid-level trough and associated jet maxima enters the
Southern Plains on Day 3/Tuesday as a lee surface cyclone evolves
across the Central Plains, promoting a fire weather threat across
the region. Lingering dry and breezy conditions are expected across
eastern NM and West TX on Day 4/Wednesday as the mid-level trough
translates eastward. Another pronounced upper trough moves into the
Pacific Northwest Day 5/Thursday. Increasing southwesterly flow
aloft ahead of the eastward propagating trough should promote dry,
downslope flow and a continued fire weather threat across the
Southern High Plains Thursday with a more widespread impact across
this region on Day 6/Friday as the amplifying trough moves into the
central U.S., eventually moving into the eastern U.S. over the
weekend. Farther east, upper-level ridging will keep much of the Mid
Atlantic and Southeastern U.S. dry through the week. The
exceptionally dry fuels and occasional elevated southerly winds will
pose a lingering fire weather threat across this region.
...Day 3/Tuesday...
...Southern Plains...
A 60-70 knot mid-level jet rounding the base of an eastward moving
trough along with deepening lee cyclone across the Central Plains
will support downslope drying and enhanced southwest winds of 20-25
mph across portions of the southern High Plains on Day 3/Tuesday.
70% critical probabilities have been introduced across southeastern
CO, far southwestern KS and adjacent NM/OK/TX border areas where
fuels remain most receptive, largely missing out on recent wetting
rainfall across the region. The 40% critical probability area
remains mostly intact for much of the southern High Plains.
...Mid-Atlantic...
A residual dry air mass under a persistent ridge aloft will remain
across the Southeast and Mid Atlantic through much of next week. A
surface low and corresponding mid-level trough moving across the
Great Lakes will promote elevated southwest winds across portions of
the Mid Atlantic. A 40% critical area was introduced into portions
of VA and NC where alignment of dry and breezy conditions and
exceptionally dry fuels is most likely.
...Day 4-6/Wednesday-Friday...
...Southern Plains...
The Southern Plains will remain a focus for fire weather concerns
through this week with a dry, downslope regime prevailing across the
region. Southwesterly flow aloft and subsequent lee surface
troughing across the central/southern Plains will support breezy
west/southwest winds and low RH each afternoon Days
4-5/Wednesday-Thursday. A 40% critical probability area was added
for Thursday across much of eastern NM, southeastern CO,
southwestern KS and adjacent TX/OK Panhandle areas. A more
pronounced and amplified upper-level trough approaches the central
CONUS by the end of the week. The associated mid-level jet streak
and deepening surface cyclone across the Central Plains will aid in
stronger west/southwest winds behind a dry line. Although recent
rainfall has mitigated wildfire spread potential in some areas,
several days of drying ahead will likely allow more receptive fuels
to develop across the southern High Plains by the end of the week.
40% critical probabilities have been introduced for Day 6/Friday
across much of southeastern NM, TX/OK Panhandles, southeastern CO
and southwestern KS.
