DISCUSSION
PARTLY CLOUDY CONDITIONS WILL BREEZY SOUTH AND SOUTHWEST WINDS WILL
PREVAIL THROUGH THE REMAINDER OF THIS AFTERNOON AND EVENING. WINDS
WILL BECOME SLIGHTLY MORE WESTERLY OVERNIGHT BUT REMAIN GUSTY AT TIMES.
ON MONDAY, EXPECT BREEZY SOUTHWEST WINDS TO LINGER DURING THE FIRST HALF
OF THE DAY, PARTICULARLY BEFORE 1400, WHEN 20-FT SUSTAINED SPEEDS ABOVE
10 MPH AND GUSTS OF 22-25 MPH CAN BE EXPECTED. THESE SPEEDS SHOULD
WEAKEN MID-AFTERNOON, WITH GUSTS FALLING CLOSER TO 15 MPH AFTER 1500.
CLEAR SKIES AND DOWNSLOPE FLOW WILL CAUSE HUMIDITY VALUES TO FALL BY
8-12 COMPARED TO TODAY, AND GIVEN RECENT FORECAST BIASES AND THE
PREDOMINANTLY SOUTH-FACING ASPECT OF THE UNIT, ANTICIPATE RH VALUES
TO FALL BELOW MODEL GUIDANCE, CLOSER TO 20% IN THE AFTERNOON.
TUESDAY WILL BRING AN INCREASE IN CLOUD COVER, COOLER TEMPERATURES,
LIGHTER WINDS AND MODERATING HUMIDITY LEVELS IN ADVANCE OF A LOW
PRESSURE SYSTEM. THIS SYSTEM IS EXPECTED TO BRING WETTING RAIN TO
THE UNITS ON WEDNESDAY (80% CHANCE).
