7/8/15 Smoky Haze with Some Relief . . . in Central Washington

Expect smoke and haze to continue through Thursday.  North winds are pushing smoke down into to the Cascade Valleys and Basin.  More Central Washington communities may see air quality in the unhealthy for sensitive groups and unhealthy ranges.  

With high temperatures today and Thursday, air quality may improve slightly as smoke becomes aloft, returning some areas to moderate levels.

Starting Thursday night, a strong cold front arrives out of the Northwest with cooler temperatures and humidity.  Initial relief from the smoke before hazy conditions return due to lighter winds and cooler temperatures.  

Looking Ahead:  Combination of Northwest fires producing heavy smoke with humid air and lighter winds . . . smoke moves smoke down valleys - we could have a smoky start to next week.

7/6/15 Calm with Smoky Haze

Hot, sunny conditions to continue through today. Northwest timber fires and several fast moving brush fires are producing smoke, creating a generalized haze in Central Washington.  See satellite image below.

Tonight NW wind should push more smoke into Central WA.  Local and newly arrived smoke will settle in most valley locations bringing compromised air quality.

Tuesday through Friday, we may have poorer air quality than we have seen so far this season  . . . expect a range from moderate to unhealthy for sensitive groups.

Stronger winds Friday afternoon should clear the air.
