.DISCUSSION...

Winds will stay light and variable for another few hours,
gradually becoming more sustained from the northwest at around 5
mph through the afternoon. RH steadily falls throughout the day to
around 25-30 percent by mid afternoon. Mixing and smoke dispersal will
increase in turn as temperatures warm.

Winds do look to pick up some tomorrow, with southwesterly gusts
around 20 mph by mid-day. With RH Friday afternoon falling to
around 20 percent, this could result in faster fire spread if any
embers persist into tomorrow.
