Smoke / Air Quality Forecast for Wednesday, August 20, 2014

Smoke Synopsis:
A bit cooler and breezy today in most locations.  Some gusty west to northwest winds 20-30 mph are possible late afternoon in and downstream of aligned canyons.  Some showers and thunderstorms are possible in the northern portion of central Washington.

We appear to have made it through the warmer, dry period this last weekend without generating any significant new fires and the firefighters were ready for Tuesday’s winds, so I would say we’re “out of the woods” – referring to smoke, not Washington’s trees.  This is reflected in the green forecast presented below.
