FIRE WEATHER PLANNING FORECAST FOR NORTHWEST CALIFORNIA
NATIONAL WEATHER SERVICE EUREKA CA
1231 AM PDT SUN JUL 5 2026
DISCUSSION
WARM AND DRY CONDITIONS WILL CONTINUE ACROSS THE
INTERIOR AREAS TODAY, WITH AFTERNOON RELATIVE HUMIDITY DROPPING
INTO THE MID-TEENS TO MID-20S ACROSS TRINITY AND LAKE COUNTIES.
FIRE ACTIVITY WILL SLOW IN RIVER VALLEYS OVERNIGHT DUE TO GOOD
HUMIDITY RECOVERIES, BUT HIGHER RIDGE TOPS WILL EXPERIENCE POOR
RECOVERY, ONLY REACHING 40 TO 50 PERCENT. THIS WILL KEEP FUELS DRY
AND ACTIVE LONGER INTO THE NIGHT ON UPPER SLOPES.
REMNANT MOISTURE MOVING NORTH FROM THE TROPICS WILL BRING A 10
PERCENT CHANCE OF AFTERNOON THUNDERSTORMS TO NORTHEASTERN TRINITY
COUNTY ON MONDAY. BECAUSE THE LOWER ATMOSPHERE REMAINS
DRY, ANY STORM THAT DEVELOPS BRINGS A RISK OF DRY LIGHTNING AND
ERRATIC WIND SHIFTS. A BUILDING INTERIOR RIDGE BRINGS A 60-70
PERCENT CHANCE OF A SIGNIFICANT HEAT WAVE BY WEDNESDAY AND THURSDAY,
WHICH WILL LIFT MIXING HEIGHTS AND PUSH VALLEY TEMPERATURES PAST 100
DEGREES.
