DISCUSSION
MOSTLY SUNNY, DRY, AND WARM TODAY FOR THE AREA. WINDS WILL START OUT
LIGHT (<10 MPH) AND WESTERLY IN THE MORNING, BECOMING BREEZIER (10-
15 MPH) AND MORE SOUTHWESTERLY IN THE AFTERNOON. MINIMUM HUMIDITIES
ARE EXPECTED TO BE AROUND 15-20%. PATCHES OF CLOUDS MAY DRIFT OVER
THE AREA STARTING AT 1300 AS HIGH-BASED/VIRGA SHOWERS DEVELOP
NEARBY. WHILE THE CHANCE FOR RAIN IS NEAR-ZERO, THE CHANCE FOR AN
OUTFLOW BOUNDARY MAKING IT TO THE BURN AREA IN THE AFTERNOON IS
ABOUT 40%, MAINLY BETWEEN 1500 AND 1800. BRIEF GUSTY WINDS UP TO 30
MPH MAY OCCUR WITH ANY OUTFLOW BOUNDARIES. SMOKE DISPERSAL WILL BE
VERY GOOD IN THE AFTERNOON. OVERNIGHT HUMIDITY RECOVERY IS EXPECTED
TO BE AROUND 50-60%.
DOWNSLOPING SW/W WINDS AT 5-10 MPH WITH SPORADIC 20-30 MPH GUSTS
WILL DEVELOP LATE TONIGHT INTO SATURDAY MORNING. BREEZY SW/W WINDS
WILL CONTINUE SATURDAY AFTERNOON, WITH OCCASIONAL GUSTS UP TO 20
MPH. HOWEVER, MINIMUM HUMIDITIES SHOULD STAY A BIT HIGHER THAN THE
LAST COUPLE OF DAYS DUE TO INCREASING HIGH CLOUDS IN THE
AFTERNOON, ONLY DROPPING DOWN TO ABOUT 30%. SMOKE DISPERSAL WILL
BE GOOD TO VERY GOOD SATURDAY AFTERNOON.
