Pioneer Fire Air Quality Forecast September 3, 2016

Air Quality Summary Report - Pioneer Fire             For: Thursday, September 3, 2016 

ARA: Mark Fitch (mark_fitch@nps.gov)                                ARA (T): Eric Dobbs (eric.dobbs@freshfromflorida.com)
FIRE, WEATHER AND SMOKE SYNOPSIS
Weather:  An upper-level trough has deepened over the Pacific northwest, weakening the pressure gradient in the low levels, which will weaken the winds significantly below ridge tops.  With a trough axis approaching, transport winds will be west to west-southwest this afternoon with speeds of 10 – 15 mph.   Up-canyon winds will be around 4 – 8 mph after 1:00pm while ridge winds will be a 8 -12 mph with gusts to 15 mph after exposed ridges; these winds will shift between southwesterly to northwesterly throughout the day.  Strongest winds in west-to-east 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 only 323 acres putting the current interpreted size to 180,300 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 to high spread rates.  Tomorrow, an increase in moisture and a good chance of showers in the late morning and afternoon will continue to decrease fire activity.
Smoke Summary:  Smoke will concentrate in the low valleys this morning and slowly mix down to the surface for much of the day.  Increased cloud cover will decrease the chances of clearing out this afternoon, but could see some lightening late this afternoon as mixing peaks.  Smoke will begin to settle into the valleys this evening, 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.  Elevated smoke plumes from the Pioneer and adjacent fires will affect Salmon and Challis areas today and this evening.
