07/30/2014 UDATED Air Quality Report

Smoke Synopsis: UPDATED
High pressure will linger over the area through the end of the work week. A slight shift in the ridge will allow temperatures to ease back down into the 90s later in the week. Short-range expect light and variable winds with upslope/downslope diurnal pattern dominating. Look for more smoke to be visible coming from within the fire perimeters as fire activity continues to increase. Smoke will settle into low-lying/valley areas overnight and lifting out with daytime heating. Models are pointing towards the possibility of mid-level moisture making its way into the area by the weekend with the potential of some isolated thunderstorms and dry lightning. Due to an increase in instability over the fires the Chiwaukum Complex became more active than anticipated. Several smoke plumes are visible and smoke is pushing north towards the areas of Twisp and Winthrop. Smoke from the Chiwaukum Complex could potentially combine with smoke from the Carlton Complex leading to moderate overnight impacts. Overnight downslope/ down-canyon winds may push more smoke in to the Leavenworth area causing heavier impacts that may be unhealthy for sensitive groups.
