Day 1 Fire Weather Outlook

Valid 041200Z - 051200Z
...NO CRITICAL AREAS...
...Synopsis...
Minimal fire weather concerns are expected across the CONUS for
today. An upper trough and associated surface low will shift into
the Upper Midwest through today, bringing precipitation and limited
fire weather threat to portions of the Deep South, Ohio River
Valley, Great Lakes and Upper Midwest. Pockets of receptive fuels
exist across the northeastern U.S., but absence of overlapping dry
and breezy conditions precludes introduction of broader fire weather
highlights.

Day 2 Fire Weather Outlook

1159 PM CST Tue Nov 03 2026
Valid 051200Z - 061200Z
...NO CRITICAL AREAS...
...Synopsis...
Limited fire weather concerns for the CONUS will carry over from
D1/Wednesday into D2/Thursday. Precipitation associated with a
surface cyclone and attendant cold front will push into the
Northeastern U.S. This will aid in fuel recovery and reduce the fire
weather threat across this region after consecutive days of above
normal temperatures and low RH were observed.

Day 3-8 Fire Weather Outlook

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.
