Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0135 AM CDT Tue Sep 30 2025

Valid 301200Z - 011200Z

...NO CRITICAL AREAS...

...Synopsis...
Fire weather potential is expected to remain limited for today
across the country, though localized concerns may emerge across
portions of the northern High Plains and Northeast.

...Northern High Plains...
06z surface observations show a deepening surface low/lee trough
across eastern MT and along the High Plains. Increasing
southwesterly flow aloft associated with the passage of an upstream
perturbation will favor further deepening and strengthening
south/southwesterly flow across the Plains. While the strongest
winds are currently expected east of the surface trough, higher
moisture content will limit RH reductions and the overall fire
threat. To the west of the trough - namely across eastern WY and
adjacent portions of NE/SD - 15-20 mph west/southwest winds are
likely with RH reductions as low as 20%. Elevated fire weather
conditions will likely develop for some locations, but recent MRMS
QPE shows patches of wetting rainfall across southeast WY over the
past 24 hours, and ERCs remain near seasonal averages. Dry grassy
fuel beds may support some fire spread, but the overall fuel
landscape does not appear conducive for broader fire concerns.

...Northeast...
North/northwesterly flow will persist today across VT, NH, and much
of ME. Latest guidance suggests sustained winds will likely remain
in the mid to upper teens, but some locations may see winds above 20
mph. An influx of drier air will promote RH reductions into the
mid/upper 30s, but the general consensus among
deterministic/ensemble solutions is that RH values will generally
remain above critical thresholds. Additionally, fuel guidance
suggests that most fuels are not overly receptive, though
grass-dominant fuel beds may support spread after several days of
dry conditions.
