FIRE, WEATHER AND SMOKE SYNOPSIS Weather: A cold front will be moving through the fire area today. The cold front will bring cooler and moister conditions. Valley winds will be west 8-12 mph, while ridge winds will be 10 - 15 mph with gusts to 20 mph over exposed ridges. The inversion will break between 11am and 1pm. Fire Activity: Decreased temperatures, and higher relative humidity (RH) values will decrease fire activity in the late afternoon today.  The most active fire activity will be seen north of HWY 17 and HWY 21 in the Warm Springs, Deadwood, and Bear Valley drainages. RH values will be around 15-20 percent in the lower valleys and 25-30 percent in the higher elevations.  Active surface fire with single and group tree torching can be expected. Wind/slope alignment may result in moderate spread rates.

Smoke Summary:  Smoke will concentrate in the low valleys this morning, then mix down to the surface for much of the day.  The majority of areas will see clearing in the early-to-late afternoon hours as daytime mixing peaks.  Smoke will again settle into the valleys in the overnight hours. Today, the most significant smoke impacts will be to Garden Valley, Lowman, Stanley and Fairfield areas.
