Day 1 Fire Weather Outlook

1054 AM CST Tue Nov 11 2025

Valid 111700Z - 121200Z

...Southwest Florida...
Cooler but very dry post-frontal flow from the north is still
expected to bring elevated to locally critical fire weather concerns
to the southwest FL Peninsula through this afternoon. Elevated
highlights were maintained across the area as north winds of up to
15 mph and relative humidity in the 20-30% range contribute to an
increased wildfire spread potential amid moderately dry fuels.

...Southern and Central Plains...
Deep layer northwesterly flow occurring over the Rockies
in addition to surface troughing across the Central Plains will
support enhanced downslope winds and drying leeward of the
central/southern Rockies today. A slight expansion of elevated
highlights were made into the Denver metro area and adjacent
foothills where sustained winds of 15 mph and relative humidity as
low 15% will align with dry fuels. A similar expansion was made into
the Trans-Pecos region of TX. Otherwise, no changes to a more
expansive elevated fire weather threat across central TX/far
southern OK resulting from dry return flow on the western periphery
of a surface high pressure anchored over the southeastern U.S.

...Synopsis...
On the backside of an amplified large-scale trough departing the
Eastern Seaboard, a dry (albeit cool) post-frontal air mass has
infiltrated the FL Peninsula. Here, a tight surface pressure
gradient and enhanced northerly low-level flow down the Peninsula
will yield dry/breezy conditions across parts of southern and
southwest FL during the afternoon. Around 10-15 mph sustained
northerly surface winds and 20-30 percent RH will favor elevated to
locally critical fire-weather conditions, given at least modestly
receptive fuels.

Farther west, a subtle/low-amplitude midlevel perturbation embedded
within moderate west-northwesterly flow aloft will overspread the
central and southern Plains during the day. This will reinforce
surface troughing and a tight pressure gradient across the region.
On the eastern periphery of the surface trough, 15-20 mph sustained
south-southwesterly surface winds combined with 20-25 percent RH
will yield elevated to locally critical fire-weather conditions
across the southern Plains. To the west, downslope warming/drying
amid the tight pressure gradient will also contribute to dry/breezy
conditions from the lee of the central Rockies into the central High
Plains. These conditions atop dry fuels will lead to a brief period
of elevated fire-weather conditions during the afternoon -- before
surface winds begin to weaken.
