8-8-14 Air Quality Report

Smoke Synopsis:
Expect similar conditions today as yesterday – westerly flow and sunny.  Expect smoke on active fires to lift out of valleys and be transported east with the transport winds.  An upper level trough is moving through the area today which will cause the surface and transport winds to die down tomorrow.  Starting tomorrow night and into Sunday expect the diurnal upslope/downslope pattern to reestablish itself.  The decrease in winds should reduce fire activity and plume rise, which along with the diurnal valley winds could cause smoke to concentrate again in valleys downslope of the fires.  Fires are now widespread across entire region with the potential to contribute to a regional smoke haze that will be evident in many cities in the Columbia River Valley.
