Air Quality Summary Report - Pioneer Fire             For: Sunday, September 4, 2016 

ARA: Mark Fitch (mark_fitch@nps.gov)                                ARA (T): Eric Dobbs (eric.dobbs@freshfromflorida.com)
FIRE, WEATHER AND SMOKE SYNOPSIS
Weather:  Deep-layer moisture will move into the area today, prompting a good chance for scattered showers this afternoon.  The deepening trough over the Pacific northwest combined with less solar heating will continue to keep winds relatively weak today.  A trough axis will pass through the area, promoting a dominant northerly component in the winds today with northeasterly winds in the morning shifting to northerly in the afternoon.   Up-canyon winds will be around 4 – 7 mph after 1:00pm while ridge winds will be a 8 -12 mph with gusts to 15 mph over exposed ridges; these winds will shift between northeasterly and northwesterly throughout the day.  Strongest winds in north-to-south oriented valleys.  Inversion will break between noon and 1pm.  Increased cloud cover will be seen for much of the day in the area.
Fire Activity:  Yesterday, the fire grew 765 acres putting the current interpreted size to 181,065 acres.  Higher RH values and increased cloud cover will help lower fire activity today.  Rising dew point temperatures this afternoon will increase surface RH values.  The most active fire activity will be seen north of HWY 17 and HWY 21 in the Clear Creek, Deadwood, and Bear Valley drainages. Grass and shrub fuels will be active for uphill runs in valley locations.  Wind/slope alignment will result in moderate spread rates; however significant spread rates are not expected.  Tomorrow, slightly drier conditions are expected which will likely marginally increase the fire activity for tomorrow.
Smoke Summary:  Smoke will concentrate in the low valleys this morning and mix down to the surface for much of the day.  Increased cloud cover will decrease the chances of clearing out this afternoon due to less mixing in the lower levels.  Smoke will begin to settle into the valleys with the biggest impacts for areas northeast, east, and directly south of the fire. Today, the most significant smoke impacts will be to Lowman, Stanley, and Garden Valley.
