Air Quality Summary Report - Pioneer Fire             For: Wednesday, September 7, 2016 
ARA: John Washington (jwashington@fs.fed.us)


FIRE, WEATHER AND SMOKE SYNOPSIS
Weather: Drier conditions will be seen today, with a slight chance of afternoon high level clouds. An upper level disturbance will leave the area today as an upper level ridge begins to build in the area. The ridge will bring a warming and drying trend over the next few days. Wind speeds will be relatively weak near the surface and aloft with transport winds primarily out of the west this afternoon.  Up-canyon winds will be around 4 – 8 mph, while ridge winds will be 7 - 10 mph with gusts to 15 mph over exposed ridges.  Inversion will break between 11am and 1pm. Over next few days expect the ridge to strengthen and bringing warmer and drier conductions supporting increase fire behavior.
Fire Activity: Increased temperatures, and lower RH values will increase fire activity this afternoon.  The most active fire activity will be seen north of HWY 17 and HWY 21 in the Clear Creek, Deadwood, and Bear Valley drainages. Relative humidity (RH) values will be around 25 – 30 percent in lower valleys and 35 – 40 percent in high elevations.  Grass and shrub fuels will be active for uphill runs in valley locations.  Wind/slope alignment may result in moderate spread rates; however significant spread rates are not expected due to low-level moisture and weak winds.
Smoke Summary:  Smoke will concentrate in the low valleys this morning and mix down to the surface for much of the day.  The majority of areas will see clearing in the mid-to-late afternoon hours as daytime mixing peaks.  Smoke will begin to settle into the valleys in the mid-to-late morning hours with the biggest impacts for areas northeast, east, and southeast. Today, the most significant smoke impacts will be to Lowman and Stanley.
