Day 2 Fire Weather Outlook

Valid 151200Z - 161200Z

...Northeastern Oregon into Central Idaho Mountains...
An embedded mid-level short wave within broader southwest flow aloft
along with residual monsoon moisture across the region will promote
showers and thunderstorms mainly along the Cascades and more complex
terrain in central and northeastern OR into central ID. Monsoon
moisture will be more diffuse across this region, generally between
0.60- 0.80" with higher values of 0.90-1.00" in the Columbia Basin.
The short wave perturbation and modest southwesterly flow aloft will
support faster moving thunderstorms (25-30 mph forward motions),
limiting rainfall in areas where fuels are still receptive. Although
some wetting rains occurred across portions of northeastern OR and
adjacent west-central ID, there still remains a broader risk of
ignitions outside of this rainfall corridor.

...Southern Plains...
Dry and breezy conditions south of a weak frontal boundary are
expected across portions of northwest OK and the TX Panhandle
D2/Saturday. This zone of overlap will be narrower than previous
days, with south winds of around 15 mph and RH falling to as low as
15 percent by peak heating Saturday afternoon. Fuels remain very dry
with notable fire activity. Added Elevated highlights across parts
of the TX Panhandle, northwest OK into far southern KS to account
for this recurring diurnal threat.

.PREV DISCUSSION... /ISSUED 0152 AM CDT Fri Aug 14 2026/

...Synopsis...
The upper ridge over the central US is forecast to continue building
rapidly as the weak western US trough is pushed northward. Showers
and thunderstorms are likely on the periphery. Beneath the ridge,
very warm temperatures are again likely over the central US
promoting low humidity, breezy winds and some fire-weather risk.

...Southern Plains...
Another day of very hot conditions is expected beneath the building
ridge across the central and southern Plains. Afternoon temperatures
in the low hundreds are likely again supporting RH minimums around
20-25%%. A weak surface low and trailing surface trough will promote
gusty southwesterly winds of 10-15 mph at the surface, albeit
slightly weaker than Friday. With little recent rainfall, area fuels
are very dry. Some locally elevated fire-weather concerns are
possible for parts of western OK and the TX Panhandle Saturday, but
the weaker winds will preclude an Elevated area.

...Northwest...
To the north and west of the upper ridge, weak troughing will
persist atop a plume of monsoon moisture. Another round of showers
and thunderstorms is likely over parts of WA/OR and into western ID.
While recent rainfall over the WA/OR Cascades should likely temper
fuels, drier conditions over eastern OR and western ID may allow
fuels to remain more receptive to lightning ignitions. Mean storm
speeds around 25 mph and relatively dry low-levels could support
some risk for dry thunderstorms Saturday afternoon and evening.
Adjustments to the IsoDryT area will likely be needed pending
rainfall amounts on Friday, but some risk for lighting over dry
fuels is apparent.
