Day 1 Fire Weather Outlook

1046 AM CST Sun Feb 01 2026
Valid 011700Z - 021200Z
...Florida...
Current surface observations across FL depict a very dry,
post-frontal northwest flow of 10-15 mph over the state this
morning. Single digit dew points and daytime heating should result
in afternoon relative humidity values close to 20 percent across the
east-central FL peninsula. Although abnormally cold temperatures
with highs only in the 40s F are expected, current fire activity
along with dry fuels, lack of significant rainfall attributed to the
frontal passage yesterday and northwest winds of up to 15 mph will
yield an enhanced fire weather concern through the afternoon. Thus,
Elevated highlights were introduced across the east-central FL.

.PREV DISCUSSION... /ISSUED 1228 AM CST Sun Feb 01 2026/
...Synopsis...
Fire weather concerns will continue to be minimal across most of the
CONUS today. Pockets of localized concerns could develop in parts of
central Florida during the afternoon. RH could fall below 30% along
the east coast of the Peninsula. Winds will be decreasing through
the day, but 10-15 mph is possible briefly. Overall, cooler
temperatures and recent light precipitation should preclude a
greater fire weather risk.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1229 AM CST Sun Feb 01 2026
Valid 021200Z - 031200Z
...NO CRITICAL AREAS...
...Synopsis...
After upper-level ridging shifts into parts of the Plains on Sunday,
a shortwave trough will lead to some breakdown of that ridge as it
dives southeastward into the central Plains on Monday. At the
surface, a modest lee trough/cyclone will develop in the central
high Plains and shift southward. Fire weather risk will broadly
remain low across a majority of the CONUS.
...Central/southern High Plains...
With the development of the lee trough/cyclone, at least modest
downslope winds appear possible during the afternoon. Winds will be
more northerly in the central High Plains. Mid/upper clouds make RH
reductions uncertain in this area. Farther south, winds in eastern
New Mexico will more likely be westerly and RH could fall below 20%.
In both areas, winds will be on the light side with around 15 mph
expected (locally up to 20 mph). This overall environment will be
conducive to fuel drying but is not expected to carry more than a
localized fire weather risk.
...Florida...
RH below 25-30% will again be possible during the afternoon. A more
relaxed pressure gradient will mean lighter winds than the previous
two days. Temperatures will be warmer, however. Without stronger
surface winds, fire weather risk appears low. Localized concerns are
possible where recent rainfall was not observed.

U.S. Day 3-8 Fire Weather Outlook

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0347 PM CST Sat Jan 31 2026
Valid 021200Z - 081200Z
...Synopsis...
Broad northwest flow with mid-level troughing is likely to persist
across the eastern U.S. through late next week. Seasonably cold
temperatures and additional opportunities for precipitation across
portions of the Southern Plains and Southeast midweek should keep
fire weather concerns minimal through much of next week. Ensemble
model guidance continues to suggest a prolonged upper-level ridging
pattern across the West, bringing above normal surface temperatures
and dry conditions to much of the Intermountain West and High Plains
through next weekend.
...Day 3/Monday - Florida...
Residual northerly flow and dry conditions across the FL Peninsula
should extend into Day 3/Monday. However, a more diffuse pressure
gradient and resultant lighter north winds is expected as a surface
high settles into the Gulf. Although low relative humidity and
warmer temperatures are likely across the peninsula Monday, recent
rainfall and diminished north winds should limit the fire weather
threat across the area.
...Days 3-6/Monday-Thursday - Central/Northern High Plains...
Fire weather concerns increase across the central and northern High
Plains Day 3/Monday. An eastward propagating mid-level wave entering
the Northern Plains and surface trough development in the lee of the
central and southern Rockies, should support enhanced downslope
drying and breezy conditions across the central and northern High
Plains early next week. Degree of drying and magnitude of RH
reductions is still uncertain, limiting confidence in introducing
Critical probabilities at this time. However, unseasonably warm
temperatures under high amplitude ridging, drying fine fuels,
particularly across the northern High Plains where snow-free
conditions exist, could increase wildfire risk in the coming days
where dry/breezy conditions align.
...Days 5-6/Wednesday-Thursday - Desert Southwest and Southern
California...
Dry conditions and relatively warm temperatures will continue across
the Southwest through the middle of next week under a building ridge
over the West. Model guidance depicts a potential cut-off low
developing near Baja California by Wednesday. Broad surface high
pressure sliding southward into the Southern Plains midweek along
with the favorably positioned mid-level low could support stronger
easterly winds across the Desert Southwest and enhanced offshore
flow across southern CA Wednesday and Thursday. However, marginal
fuels could limit overall impact from dry/breezy conditions limiting
predictability for the midweek time frame.
