Smoke Synopsis: Friday morning update
Most stations in the area reached “Unhealthy” and “Unhealthy to Sensitive Groups” level yesterday.  Hayfork was in “Hazardous” level.  Good to excellent day-time mixing is expected during the day for the next few days.  Transport wind speed will gradually increase from today through Monday.  However, the transport wind direction will shift from Northwesterly today to Westerly tomorrow to Southerly flow on Sunday.  Heavy smoke is still likely in river drainages in Shasta-Trinity National Forest during the overnight periods until inversion break the following morning.
