.DISCUSSION...
STABLE DEEP MARINE LAYER UP TO NEAR 6000 FEET CONTINUES TO SPILL INTO BUT
ERODE INTO THE BURN AREA. THIS IS KEEPING HUMIDITY ELEVATED. HOWEVER...
WINDS WILL CONTINUE AND BECOME STRONGER THIS AFTERNOON AND
ESPECIALLY THIS EVENING. THIS IS WHEN GUSTS TO 35 MPH ARE EXPECTED.
A RATHER STRONG COLD FRONT WILL MOVE OVER THE FIRE TONIGHT...NEAR
MIDNIGHT FOR PASSAGE...AND WINDS WILL SHIFT TO THE NORTHWEST.
WINDS GUSTS OF 25 TO 30 MPH WILL CONTINUE THROUGH SATURDAY IN A
MUCH MORE UNSTABLE COOL AIR MASS WITH MODERATE HUMIDITY.
PRECIPITATION CHANCES ARE ONLY FROM A STRAY SHOWER TONIGHT. THE
WIND WILL DECREASE TO LIGHT SATURDAY NIGHT FOR VALLEY AND RIDGE
TOPS...AND THEN TURN OFFSHORE NORTH TO NORTHEAST EARLY SUNDAY
MORNING BEFORE GRADUALLY TURN TO DIURNAL UPSLOPE SUNDAY AFTERNOON.
