SERVICE.
DISCUSSION
WIND CONDITIONS ARE CURRENTLY VERY LIGHT IN THE AREA, FAVORING A
DIRECTION OUT OF THE NORTH (I.E. DOWN-CANYON) THROUGH OWL CANYON WITH
4-7 MPH OR LESS EXPECTED TO CONTINUE THROUGH AT LEAST 0800-0900.
STARTING 0900, BUT MORE LIKELY CLOSER TO 1000, STRONGER WINDS SHOULD
BEGIN TO MIX DOWN WITH PREVAILING NORTHWEST DIRECTION. THERE IS LITTLE
INDICATION THAT THE HOGBACK DUE WEST WILL SIGNIFICANTLY IMPACT WIND
SPEEDS NEAR THE HWY 287/CR 72 INTERSECTION, LIKELY BECAUSE THE PREVAILING
FLOW DIRECTION (FROM THE NW) WILL BE QUITE WELL-ALIGNED WITH THE GAP/CHANNEL
ASSOCIATED WITH HWY 287. WITH THAT, EXPECT PEAK SUSTAINED WINDS 13-18 MPH
FROM MIDDAY THROUGH APPROXIMATELY 1800, WITH GUSTS 26-32 MPH. POTENTIAL FOR
ANY SOUTHERLY WIND COMPONENT APPEARS TO BE LOW, WITH RELATIVELY HIGH
CONFIDENCE IN WIND DIRECTIONS REMAINING WNW/NW THROUGH THE DAY.
TEMPERATURES WILL CLIMB TO NEAR 80F THIS AFTERNOON, WITH MINIMUM HUMIDITY
14-17%. VENTILATION RATES WILL BE HIGH, PARTICULARLY AS WINDS BEGIN TO MIX
DOWN MID TO LATE MORNING, AND CONTINUING THROUGH THE AFTERNOON GIVEN
DEEPENING MIXING HEIGHTS AND HEALTHY TRANSPORT WINDS ALOFT. TRANSPORT
WINDS WILL ALSO CARRY A PREVAILING DIRECTION FROM THE WEST-NORTHWEST.
