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. ..Weinman.. 11/11/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
