Day 3-8 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0353 PM CDT Thu Aug 29 2024

Valid 311200Z - 061200Z

...Day 3/Saturday - Isolated Dry Thunderstorms...
A large-scale ridge will remain in place across much of the West,
while a midlevel low and related height falls begin to impinge on
the Pacific Northwest. Given gradually increasing midlevel moisture
along the Cascades, and terrain-driven ascent, an isolated
thunderstorm cannot be entirely ruled out. However, confidence in
this scenario is too low for Isolated Dry Thunderstorm probabilities
at this time. Farther south, the northern periphery of a deeper
moisture plume will phase with ample diurnal heating and orographic
ascent over the higher terrain across portions of southern NV into
southwest UT. This will promote isolated dry thunderstorms atop
modestly receptive fuels during the afternoon/early evening.

...Days 4-5/Sunday-Monday - Isolated Dry Thunderstorms...
The above-mentioned midlevel low will advance east-northeastward
across northern CA/southwest OR on Day 4/Sunday, and continue
east-northeastward across OR into ID on Day 5/Monday. Isolated dry
thunderstorms will be possible across south/central OR on Day
4/Sunday, with increasing potential into the overnight hours -- as
midlevel moisture/instability increases ahead of the midlevel low.
Thereafter, the risk of mixed dry/wet thunderstorms will continue
spreading/expanding eastward across eastern OR into ID -- in tandem
with the midlevel low/trough. While fuel receptiveness across the
region is uncertain, several days of boundary-layer drying (beneath
the large-scale ridge) preceding this thunderstorm event will pose
at least some risk of lightning-induced ignitions.

Thunderstorm potential will continue across the northern Rockies on
Day 6/Tuesday, though gradually increasing moisture and
precipitation cast uncertainty on the overall fire-weather risk --
precluding Isolated Dry Thunderstorm probabilities.
