.DISCUSSION...
MOSTLY CLOUDY CONDITIONS IN THE FORM OF MID TO HIGH LEVEL CLOUDS ARE
EXPECTED TODAY OVER THE BURN SITE WITH THE SUN ABLE TO PENETRATE
WHERE CLOUDS ARE NOT AS OPAQUE. ALTHOUGH WINDS ARE LIGHT,
ANTICIPATING THAT DISPERSION INDEX WILL BE GENERALLY GOOD. MINIMUM
RELATIVE HUMIDITY VALUES MAY DROP CLOSE TO 30% BY 2PM-4PM AS MIXING
HEIGHTS RISE CLOSE TO 2400 FEET BY IGNITION TIME AND NEAR 5500 FEET
BY 2PM. THE DROP IN RELATIVE HUMIDITY VALUES WILL LIKELY BE SLOWER ON
THE WEST ASPECT OF THIS BURN (CLOSER TO 3 PM) THAN THE EASTERN AND
SOUTH ASPECT DUE TO SUN ANGLE/ASPECT.

KBDI VALUES SHOULD HOLD BELOW 300 TODAY AND SUNDAY. IN ADDITION, FOG
POTENTIAL TONIGHT SHOULD BE LIMITED.

THEN, ON SUNDAY, ANTICIPATING SUNNY CONDITIONS, SOUTHWEST WINDS OF
5-8 MPH BY LATE MORNING, AND GUSTY WINDS BY THE AFTERNOON AS A COLD
FRONT APPROACHES SUNDAY NIGHT. DISPERSION SHOULD STILL BE GENERALLY
GOOD TO GOOD BY SUNDAY AFTERNOON.
