...Synopsis...
Fire weather concerns will remain low across the contiguous U.S.
today. Additional rainfall associated with a mid-level trough over
the central U.S. will continue to suppress fuels across the Southern
Plains, northward into the Upper Midwest. Dry conditions including
RH as low as 30% and above normal temperatures are expected across
much of the Northeast today amid receptive fuels. However, weak
surface pressure gradients influenced by surface high pressure
extending into the Mid-Atlantic should maintain light winds through
today, reducing the overall fire weather threat.

.PREV DISCUSSION... /ISSUED 1149 PM CST Mon Nov 02 2026/
...Synopsis...
Minimal fire weather concerns are expected across the CONUS for
D2/Wednesday. An upper trough complemented by a surface cold front
and associated precipitation will push into the Upper Midwest, Great
Lakes and Appalachians. Despite lingering dry conditions ahead of
the upper trough amid pockets of receptive fuels across the
northeastern U.S., surface winds will remain light, precluding
introduction of fire weather highlights.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0353 PM CST Tue Nov 03 2026
Valid 051200Z - 111200Z
Upper-level troughing will move over the eastern third of the CONUS
with another (smaller) trough on the eastern edge of the
Intermountain West on Day 3/Thursday. By Day 4/Friday, upper-level
ridging will build in over much of the western US, transitioning
temperatures from below or near-normal to above normal starting this
weekend. Consensus of the latest forecast guidance is that this
ridge, while not particularly strong, will persist through
mid-next-week. A cold front progressing across the eastern states
will bring beneficial rainfall to much of the Appalachian Mountains.
A shortwave trough behind the first trough will bring additional
opportunity for precipitation to the southern Plains and Gulf Coast.
Meanwhile, an upper-level low over Baja CA on Day 4/Friday through
Day 6/Sunday will support easterly flow and result in moderately
strong Santa Ana surface winds. Even with drying conditions present
as this system transits the region, recent rainfall accumulation and
increased live fuel moisture are expected to limit the fire threat
there. Nevertheless, fire weather concerns will be reduced across
almost all CONUS locations through the forecast period given recent
rainfall and subdued fuels.
