Steady winds, between 10-15 mph, are expected through the afternoon with gusts up to 25 mph through late this morning, falling to around 20 mph this afternoon. Lowest humidity, around 1400-1500, could fall as low as 35-40% but critically low humidity is not anticipated. For Saturday, high pressure will expand into the region. This will ease winds, lower dispersions, boost temperatures. Winds will shift onshore and trend humidity higher. Have a safe burn! .REST OF TODAY...
