DISCUSSION
THERE IS SOME UNCERTAINTY SURROUNDING THE PATTERN FOR EARLY NEXT
WEEK. A LOW PRESSURE SYSTEM PASSING TO THE NORTH ON SUNDAY WILL
ALLOW THE MARINE LAYER TO DEEPEN, WHICH SHOULD KEEP RELATIVE
HUMIDITES HIGH. HOWEVER, THERE IS A CHANCE FOR WEAK OFFSHORE FLOW
BEHIND THE SYSTEM ON MONDAY. IF FLOW TURNS OFFSHORE, THEN
RELATIVE HUMIDITIES MAY BE LOWER THAN CURRENTLY EXPECTED AND
WINDS MAY BE OUT OF THE NORTHEAST. NOT EXPECTING ANY SANTA ANA
WINDS. OTHERWISE, A SUBTLE WARMING TREND IS ANTICIPATED FROM
MONDAY THROUGH MID-NEXT WEEK.
