Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0954 AM CDT Wed Aug 27 2025

Valid 271700Z - 281200Z

IsoDryT area was trimmed in portions of eastern Washington,
northwest Montana, and the Idaho Panhandle. PWAT values are
generally over 1" for much if not all of the IsoDryT area today, and
the possibility of training storms today and development of showers
and wet thunderstorms in following days over the same locations
lowers confidence in the outlook. Additionally, locally elevated
conditions are likely in portions of central into northwest Montana
east of the Rockies as breezy easterly winds develop amid a modestly
dry airmass.

...Synopsis...
A pair of convectively augmented midlevel lows will track northward
across the Northwest today. The associated forcing for ascent
coupled with an influx of deepening midlevel moisture will support
sufficient buoyancy for isolated/embedded lightning within
high-based showers. While storm coverage may be somewhat limited
(5-10 percent), any embedded storms may pose a risk of
lightning-induced ignitions and locally gusty winds across parts of
WA into the ID Panhandle and far northwest MT, given dry fuels.
Farther south, a continuation of mixed wet/dry thunderstorms are
expected across OR into northern CA, though preceding days of modest
rainfall limits confidence in the overall threat.
