DISCUSSION
AS A THIN SECTION OF HIGH PRESSURE ENTERS THE AREA, WINDS
WILL SHIFT AND MIXING HEIGHTS WILL REMAIN RELATIVELY LOW, ESPECIALLY DUE
TO THE PROXIMITY OF THE COASTLINE. OFFSHORE NE WINDS TODAY WILL PERSIST
THROUGH THE NIGHT. SUNDAY BRINGS SE WINDS TO THE BURN SITE. GUSTS WITH
THESE SE WINDS COULD BE OROGRAPHICALLY ENHANCED ALONG THE RIDGES UP TO 20MPH.
RH VALUES OVERNIGHT ARE EXPECTED TO BE AROUND 80% DUE TO OFFSHORE FLOW AND
HIGH PRESSURE COMPRESSING AND PUSHING THE MARINE LAYER AWAY FROM THE BURN
SITE.
