.DISCUSSION...
SUNNY AND WARM CONDITIONS WITH EXTREMELY LOW RELATIVE HUMIDITIES
WILL PERSIST THROUGH THIS AFTERNOON. TEMPS SHOULD CLIMB ONLY A FEW
MORE DEGREES FROM CURRENT READINGS..WITH NEARLY STEADY TEMPS IN
THE LOWER 70S INTO EARLY THIS EVENING. WINDS SHOULD BE SUSTAINED
FROM THE SOUTH-SOUTHEAST AROUND 10 MPH..BUT THERE COULD BE A FEW
PERIODS OF GUSTS UP TO THE 15-17 MPH RANGE. RELATIVE HUMIDITIES
SHOULD HOLD STEADY THROUGH MOST OF THE AFTERNOON IN THE 13-16
PERCENT RANGE.

BETWEEN 6 AND 8 PM THIS EVENING..WINDS SHOULD DECREASE IN SPEED
INTO THE 5-8 MPH RANGE..AND GUSTINESS IS EXPECTED TO END AS WIND
DIRECTION BECOMES MORE SOUTHEAST TO EAST ESPECIALLY AFTER SUNSET.

READINGS NOT RECOVERING TO BACK ABOVE 40 PERCENT UNTIL BETWEEN 9
AND 10 PM AT THE EARLIEST.
