Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1024 AM CDT Fri Aug 09 2024

Valid 091700Z - 101200Z

The previous forecast remains on track with some expansion of both
isolated dry-thunderstorm risk areas needed based on recent
observations and trends in latest guidance. 

...northern Rockies...
As of 15 UTC, isolated lightning strikes were noted across portions
of southern ID and northern UT. Negligible MRMS rainfall rate and
1-hour accumulation estimates associated with this convection
suggests that little rainfall is reaching the surface. Given the
very dry sub-cloud layer noted in the 12 UTC BOI sounding and an
extensive plume of agitated mid-level cumulus, the potential for
isolated dry thunderstorms appears to be more widespread than
previously forecast. 

...northern Washington...
To the northwest across north-central WA, convection along the
international border appears to be producing areas of wetting
rainfall based on MRMS rainfall estimates. However, the 12 UTC OTX
sounding amd GOES PWAT estimates suggest drier conditions exist east
of the Cascades where a convective signal is noted in 12 UTC CAM
guidance. 

...northeast Nevada...
Areas of breezy/dry conditions remain likely this afternoon across
northeast NV; however, morning guidance continues to suggest that
elevated fire weather conditions should remain fairly isolated and
transient given an overall nebulous/weak synoptic regime.

.PREV DISCUSSION... /ISSUED 1238 AM CDT Fri Aug 09 2024/

...Synopsis...
A subdued upper-level ridge will persist within the Great Basin into
part of the northern Rockies. In the Northwest, a low-amplitude
upper trough will make gradual progress eastward through the day.

Some isolated thunderstorm activity, some of which may be dry, is
possible in the northern Cascades as well as central Idaho into
western Wyoming. Storm motions in Washington will a touch on the
slow side, make a mix of wet/dry storms probable. Storms have some
potential to be drier in the northern Rockies given the belt of
stronger mid-level winds aloft. Fuels within the terrain have
generally received lower rainfall amounts recently and fuels indices
suggest some degree of receptiveness.

Marginally dry and breezy conditions are also expected in the lee of
the northern Sierra into adjacent parts of the northern Great Basin.
Winds will not be overly strong and any sustained elevated
conditions are likely to be spatially limited.
