Day 3-8 Fire Weather Outlook

Valid 291200Z - 041200Z

A closed upper low will approach the Pacific Northwest Coast Day
3/Friday - Day 4/Saturday, but forecast guidance has been
inconsistent on how far inland the low moves over British Columbia
and Washington. Forecast guidance has been increasingly consistent
in the low retrograding back offshore early next week. Meanwhile,
upper-level ridging will slowly build back over the West, especially
the Intermountain West, this weekend through early next week with a
warming and drying trend. Thunderstorm coverage will diminish across
the West and likely be mostly confined to portions of the Four
Corners region this weekend into early next week.

...Day 3/Friday - Day 5/Sunday...
As the upper low approaches the Northwest, dry/breezy conditions are
likely in portions of northern California, Inland Northwest, and
northwest Great Basin Day 3/Friday - Day 5/Sunday. Current forecast
guidance indicates the potential for locally elevated winds/RH and
low probabilities of critical conditions. However, given the recent
lightning, holdovers will be a concern. Established fires are also
likely to see increased burn periods and lower RH/higher winds
helping to increase spread potential.

Isolated drier thunderstorms are possible ahead of the upper low
across portions of the Northwest, northwest Great Basin, and
northern Rockies Day 3/Friday and possibly into Day 4/Saturday.
However, too much forecast uncertainty exists to include
probabilities at this time. Showers are likely for portions of
northwest Oregon and western Washington associated with the upper
low Day 3/Friday into Day 5/Sunday.
