Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0436 PM CDT Tue Jul 16 2024

Valid 181200Z - 241200Z

The pattern in the extended D3/Thur-D6/Fri will feature a trough
moving across the northeastern US as strong high pressure continues
to build across the western US. Late in the extended period, a
deepening trough will potentially move across the Pacific Northwest,
with an attendant cold front D6/Sun-D7/Mon bringing increasing winds
and potential thunderstorm chances.

...Pacific Northwest D3/Thursday - D8/Tuesday...
On D3/Thur, a band of enhanced southwesterly flow aloft will
overspread the Cascades, bringing increased surface winds that will
overlap relative humidity around 10-15 percent. A 40% delineation
was maintained with this outlook. Given the potential for dry
lightning on D2/Wed, fire spread with new lightning ignitions will
be possible.

Moisture will gradually begin to increase northwestward across
California into Oregon and Washington towards the weekend as
deepening trough brings southerly flow back into the region. This
will bring an increase in thunderstorm activity as well as the
potential for increasing winds.

...Great Basin, Idaho, and Arizona D3/Thursday - D8/Tuesday...
Across the western US where high-amplitude ridging continues,
drying conditions and very warm temperatures are expected. Isolated
dry thunderstorm chances will continue across portions eastern
Nevada and far southern Idaho D3/Thur.

Monsoonal moisture will gradually shift southward out of the Great
Basin residing across southern Nevada/Utah/Arizona where
thunderstorm chances will continue. Isolated dry thunderstorms may
be possible across portions southern Utah and eastern Nevada, along
the northern periphery of the better monsoonal moisture through the
end of the period.
