FRIDAY JULY 4TH OBSERVATIONS NEAR THE COMPLEX OF FIRES REPORTED
MAX TEMPERATURES IN THE UPPER 80S TO LOW 90S, WITH MINIMUM RH
VALUES NEAR 20 PERCENT. WINDS INCREASED OUT OF THE NORTHEAST IN
THE EVENING, PEAK GUSTS REACHING 15 MPH. EARLY THIS SATURDAY
MORNING WE ARE SEEING EXCELLENT RH RECOVERY IN THE VALLEYS, WITH
SITES REPORTING VALUES IN THE 90 TO 100 PERCENT RANGE. WITH THAT
SAID, THE BUCKLEY BAR FIRE IS LIKELY SEEING MORE ACTIVE FIRE BEHAVIOR
IN THE UPPER TERRAIN DUE TO THE THERMAL BELT ABOVE THE INVERSION.
MOVING THROUGH SATURDAY WE WILL SEE TEMPERATURES CLIMB BACK UP

EXPECT EAST-NORTHEAST WINDS TO CONTINUE, WITH GUSTS LARGELY
REMAINING BELOW 20 MPH. SUNDAY, LIGHT WINDS BECOME
MORE SOUTH-SOUTHWESTERLY IN THE LATE AFTERNOON, AS A RIDGE BREAKS DOWN
ACROSS THE STATE. THIS FEATURE WILL BRING BACK COOLER TEMPS,
