07/30/2014 Air Quality Report

Smoke Synopsis:
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.
