FIRE WEATHER PLANNING FORECAST FOR NORTHWEST CALIFORNIA
NATIONAL WEATHER SERVICE Eureka CA
1211 AM PDT Mon Jun 16 2025
...Locally elevated fire weather conditions expected Monday and
Tuesday afternoons and evenings in Zone 264...
.DISCUSSION...Slightly cooler inland temperatures are forecast
today. Another shortwave moving toward the area with a front will
bring some shower potential in northeastern Trinity, but
thunderstorm chances remain low (5% or less) as instability
remains meager. Northerly afternoon winds increase today,
particularly in Mendocino and Lake counties. Low afternoon RH
between 15 and 25% will allow for areas of locally elevated fire
weather conditions. Breezy northerlies continue through the week,
with stronger winds possible late week. Minimum RH values may
trend upward slightly behind a weak front, but elevated to locally
critical fire weather conditions are still possible.
