8-10-14 Air Quality Report

Smoke Synopsis:
Very hot and dry conditions will exist over the area today and Monday, with lower elevations reaching 100 degrees and even upper elevations into the 80s with low relative humidities.  It will be quite stagnant with mostly light winds, creating the potential for thick smoke in areas near and downwind of fires, especially during night and early morning hours.  Dispersion will be generally poor, as well, with only limited afternoon mixing of the atmosphere.  There may be slightly improved dispersion by Tuesday as a weather system approaches, but thunderstorms and lightning will become more probable then.  More clouds and showers are possible Wednesday, with improving air quality.
