Air Quality Forecast:  Today, a finger of light smoke is expected to move west from the Douglas and Big Windy Fires, over the coast, between Humbug Mountain State Park and Gold Beach, and curl back, eventually bringing light smoke into Brookings.   Inland, air quality patterns will be similar to yesterday.  Peak periods of dense smoke will be experienced in the morning in Provolt, Medford, Grants Pass, and Klamath Fall.   Glendale and Cave Junction will experience peak concentrations just before the inversion breaks, typically around noon.   Merlin and Crater Lake will experience peak concentrations in the early evening.   Shady Cove will experience peak concentration in the afternoon.
