8-11-14 Air Quality Report

Smoke Synopsis:
Stagnant conditions have produced a region-wide haze since Saturday night, with localized areas of dense smoke and very poor air quality.  These conditions will gradually improve on Monday with very hot afternoon temperatures and moderately low humidities.  Winds will continue to be quite light through Tuesday.  Dispersion conditions will slightly improve later Monday, and improve a bit more on Tuesday.  The air flow at mountain elevations will be mostly southeasterly through Tuesday, and will increase some by Tuesday.  Some very scattered thunderstorms are possible Monday night, and will become more widespread and possibly stronger Tuesday afternoon and night.
