Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1043 AM CST Sat Jan 31 2026
Valid 311700Z - 011200Z
...NO CRITICAL AREAS...
No changes to Day 1 Fire Weather Outlook were needed. Stronger
northwest winds of 15-25 mph associated with a strong cold front
will continue to spread into the FL Peninsula today. Relative
humidity within the dry, post-frontal air mass will fall to around
30 percent this afternoon, concentrated along the southern AL/GA and
FL Panhandle region. High temperatures primarily in the 30s F
coupled with marginal fuel dryness will limit a broader fire weather
threat across the region where dry and breezy conditions align.
However, pockets of drier fuels may support a locally elevated
wildfire spread potential this afternoon across the northern Gulf
Coast.

...Synopsis...
A deepening surface low off the Mid-Atlantic coast will drive 15-20
mph surface winds down the Florida Peninsula today. It is possible
that marginal RH reductions may occur along the Florida-Georgia line
(30-35% during the afternoon). However, light precipitation was
observed on Friday which will dampen fuels. Coupled with
temperatures in the 40s F, fire weather concerns will likely remain
minimal. Elsewhere within the CONUS, combinations of cool/cold
temperatures, light winds, and poor fuel receptiveness will preclude
concerns.

U.S. Day 2 Fire Weather Outlook

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0134 PM CST Sat Jan 31 2026
Valid 011200Z - 021200Z
...NO CRITICAL AREAS...
...Florida...
A very dry, post-frontal air mass being advected into FL will result
in daytime relative humidity 25-35 percent range by Sunday
afternoon, with eastern peninsular locations falling to around 20
percent. Northwest winds of 10-15 mph will gradually subside through
Sunday afternoon as the deep surface low east of the Carolinas
accelerates northeastward. Recent light but widespread rainfall
across central/southern FL, marginally dry fuels and cool
temperatures primarily in the 40s F should still mitigate
significant fire weather concerns for Sunday, precluding the need
for broader Elevated highlights.

.PREV DISCUSSION... /ISSUED 1140 PM CST Fri Jan 30 2026/
...Synopsis...
The potent upper-level trough on the East Coast and associated
surface cyclone offshore will lift northeastward with time on
Sunday. Surface high pressure and colder air will shift eastward
into the more of the eastern U.S.
...Florida...
Confidence in reduced RH during the afternoon is higher than on
Saturday. RH of 25-35% appears possible along the eastern Peninsula.
As with Saturday, temperatures will remain on the cool side. More
importantly, winds speeds will be on a downward trend through the
period. Given this expected environment, fire weather risk is
expected to remain low.
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.
