Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
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.

...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
0151 PM CST Sun Feb 01 2026
Valid 021200Z - 031200Z
...NO CRITICAL AREAS...
...Central/Southern High Plains...
Westerly flow aloft over the southern Rockies ahead of an
approaching mid-level trough, along with lee cyclone development
across eastern NM and the TX Panhandle will support breezy
conditions across the central/southern High Plains Monday. Primary
driver of elevated north/northwest winds from southeastern WY,
eastern CO and western KS, will be an evolving cold front north of
the deepening surface low near the TX Panhandle. North/northwest
winds of 15-20 mph are expected amid relative humidity in the 20-25%
range across the central High Plains. A drier, downslope
presentation is expected farther south with RH falling to as low as
15% across portions of eastern NM and the TX Panhandle coinciding
with west/southwesterly surface flow approaching 20 mph by
mid-afternoon. Localized elevated fire weather concerns are likely,
but marginally dry fuels across the region should mitigate a wider
fire weather concern.
...Florida...
Forecast remains consistent with lighter northwesterly winds across
the FL peninsula Monday as high pressure settles into the northern
Gulf. Very dry conditions will remain with RH falling to around 25%
in interior locations, but inhibited winds should mitigate a broader
fire weather threat.

.PREV DISCUSSION... /ISSUED 1229 AM CST Sun Feb 01 2026/
...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
0334 PM CST Sun Feb 01 2026
Valid 031200Z - 091200Z
...Synopsis...
A broad upper-level troughing pattern across the eastern U.S. and
ridging across the West is likely to persist through much of this
week. Longer term ensemble guidance suggests a slow deamplification
and shift eastward of the ridge into the Great Plains early next
week which could allow more favorable Pacific moisture trajectories
into the Pacific Northwest and Northern Rockies by Day 8/Sunday. At
the surface, another southward advancing cold front and related
mid-level trough encountering increasing lower-level Gulf moisture
will support widespread precipitation from eastern TX on Day
3/Tuesday into much of the Southeast by Day 4 Wednesday, mitigating
fire weather concerns. Dry conditions and above normal temperatures
are expected under the ridge for the West and into the High Plains.
...Days 4-5/Wednesday-Thursday - Desert Southwest and Southern
California...
A developing mid-level low near Baja California, along with an
emerging sustained east-to-west surface pressure gradient should
augment stronger easterly winds across the Desert Southwest and
southern CA by midweek. Persistently low relative humidity
(including poor overnight recoveries) are likely to persist through
midweek. Although alignment of dry and breezy conditions are
probable, a marginally dry fuelscape should allay a more significant
fire weather concern Wednesday and Thursday.
