Though high pressure will build, winds will remain out of the north, with gusts of upwards of 15-17 mph during the afternoon hours. During the overnight hours into Sunday, a dry cold front will graze the burn area, bringing an increase in windspeed during the overnight hours. Much of the wind will be seen on higher elevation ridges and slopes with greater exposure to the northwest during the overnight hours. By Sunday, these winds will increase in speed out of the northwest with gusts approaching the 25 mph for the higher exposure terrain during the morning and early afternoon hours. A gradual decrease in wind speed is expected through the afternoon on Saturday as high pressure strengthens. Warming and drying is anticipated over the burn through Sunday, with another grazing storm following quickly in its heels. .TODAY... Sky/weather.........Mostly sunny (25-35 percent cloud cover).
