104 PM PDT Thu Oct 1 2026
.DISCUSSION...Unseasonably hot and dry conditions build late week and
peak this weekend increasing fire danger. By Saturday, many interior
valleys will reach into the upper 90s with daytime RH around 15
percent. Mid and upper elevation RH recovery will become
increasingly poor with strengthening thermal belts. Winds will be
weak and terrain driven. Marine influence will be very shallow along
the coast. Conditions will slowly ease next week, though there
remains essentially 0% chance of wetting rain within the forecast
period.
