Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1239 AM CST Tue Nov 18 2025
Valid 181200Z - 191200Z
...NO CRITICAL AREAS...
...Synopsis...
Critical fire weather concerns are not expected for today across the
country, though localized concerns may emerge across portions of the
Southeast and southern Appalachians this afternoon. Early-morning
satellite imagery depicts a weakening upper wave over the central
Plains. This feature, along with an attendant surface low, will
shift eastward into the OH Valley through this evening. Across the
West, another upper wave continues to drift southward along the CA
coast. Strong low-level winds are expected to accompany both of
these systems, however, increasing showers/thunderstorms coincident
with the breezy conditions will mitigate fire weather concerns.
Elsewhere, surface winds are expected to remain sufficiently benign
to limit the fire weather threat.
...Georgia into the Carolinas...
Dry conditions are expected to continue across GA into the Carolinas
for today. Southerly winds will help advect some returning moisture
into the region, but ensemble consensus is that RH minimums in the
20-30% range will be common once again. Surface high pressure will
limit wind speeds to mainly near/below 10 mph based on the 90th
percentile of recent HREF/NBM runs. However, a few locations,
especially at higher elevations, may see occasional gusts upwards of
15-20 mph that may support very localized fire weather concerns.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0110 AM CST Tue Nov 18 2025
Valid 191200Z - 201200Z
...NO CRITICAL AREAS...
...Synopsis...
The potential for critical fire weather conditions appears limited
for Wednesday. Latest guidance shows reasonably strong agreement in
the eastward translation of the southern CA upper low into the Four
Corners region over the next 48 hours. Modest lee
troughing/cyclogenesis is expected as this occurs, but the low-level
wind response is expected to be fairly muted with around 10-15 mph
sustained winds across parts of the southern High Plains.
Additionally, scattered to widespread mid/high-level cloud cover is
anticipated, which will modulate diurnal heating and most likely
limit RH reductions to the 25-35% range. Recent ensemble guidance
hints that some mid-afternoon clearing is possible across far
northeast NM into the OK/TX Panhandles, which may be sufficient for
a pocket of sub-25% RH and winds between 15-20 mph. However, this
potential appears too limited/localized to warrant risk highlights
at this time.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0332 PM CST Mon Nov 17 2025
Valid 191200Z - 251200Z
Fire weather concerns across the CONUS remain low through early next
week. A deep mid/upper trough and associated enhanced mid-level flow
pivoting through the Southwest through midweek brings a region of
broad lift/ascent to the Southern Plains over an northward advancing
warm front by Day 3/Wednesday. Anomalously high boundary layer
moisture ahead of the upper trough will support much needed
widespread showers and thunderstorms across the Southern Plains from
Days 3-5/Wednesday-Friday. This should mitigate fire weather
concerns where fuels still remain quite dry and receptive to fire
spread. An evolving surface low over the Southern Plains late this
week and accompanying frontal boundary moves into the Southeast by
Saturday, bringing additional rainfall and reduced fire weather
concerns to much of Ohio River Valley, Mid-Atlantic and Southeast.
Another mid-level trough and sufficient low-level Gulf moisture
provides additional opportunities for precipitation to the Southern
Plains early next week. However, uncertainty in timing and expected
state of fuels renders little confidence in fire weather impacts to
the region at this time with no critical probabilities introduced.
