.DISCUSSION...

High pressure overhead today results in sunny skies and dry
conditions. An approaching weather system to our west will help to
slowly increase southeasterly winds throughout the day. With
lighter winds in the morning, poor to fair smoke dispersal is
expected at ignition time. Minimum relative humidity values in the
afternoon will be around 25 percent. Winds will also increase
overnight into Friday as the system gets closer. Wet and windy
