HIGH PRESSURE RIDGE ALOFT WILL SLOWLY WEAKEN TODAY THROUGH FRIDAY
AS A TROUGH APPROACHES THE CENTRAL CALIFORNIA COAST.
THIS SHOULD RESULT IN INCREASING WEST WINDS AND INCREASING
HUMIDITY THROUGH THE REMAINDER OF THIS WEEK.

FOR TODAY...MARINE LAYER DEPTH IS NEAR 2200 FEET THIS MORNING...
EXPECT IT TO DEEPEN TO 2800 FEET THIS AFTERNOON. A THERMAL BELT
WILL BE PRESENT AT ELEVATIONS BETWEEN 3500 AND 5700 FEET. EXPECT
THE LOWEST HUMIDITY AT THESE ELEVATIONS TO BE IN THE SINGLE
DIGITS AND OCCUR DURING THE LATE NIGHT AND EARLY MORNING
HOURS.
