Sunday Update for Washington State

The cooler weather, onshore winds, and scattered rain will continue today as the clouds move east.  We should be back to clear skies on Monday afternoon and Tuesday.  Not for long though!  More cloudy and cool weather is expected to roll in on Wednesday.   Thanks to the weather, many Washington residents will continue to see relatively good air quality today and beyond.  However, it can be difficult to assess fire and smoke activity with all these clouds since satellites do not have a clear view.

Most of Western Washington is experiencing Good air quality, but a fire on JBLM has been sending smoke north and causing Moderate to Unhealthy air quality around the Seattle area.  The fire is contained but could continue to generate modest smoke that impacts nearby cities.

Northerly winds are expected on Monday, which could blow a little Canadian smoke into our state, but nothing like we saw earlier this year.  Residents in the Spokane area could also see smoke blow in from Idaho and Montana.  It should be short lived though, since Tuesday's forecast shows westerly winds are expected for the coast and southerly winds for Eastern Washington.

All in all, sporadic rain and shifty winds should keep air quality pretty good in our state, but if you are downwind from a fire you should expect some smoke.

Large Washington Fires:

McLeod, Cougar Creek, and Crescent Mountain in the North/Central Cascades are the largest fires in the state and continue to send smoke to various parts of Central and Eastern Washington.

The Boyds fire in Ferry county and the Horns Mountain fire in Stevens county have been impacting northeastern Washington, including Spokane.

The Maple fire on the southeast side of the Olympic National Park has seen minimal growth (currently 2,150 acres).

The Miriam and Meninick fires continue to generate moderate smoke for Yakima county.

PM2.5 monitors on Sunday (10 am)

Smoke returns to eastern WA, western WA on track to get a whiff. Improvement on Thursday

Image
Active weather over the last week helped most of the state breathe easy. But much of eastern WA took a turn for the worse last night with fine particle pollution levels ranging from Moderate to Unhealthy. Wildfires in Okanogan County and BC (just north of Stevens County) are the main culprits. Here's what the latest satellite picture looks like. A thin layer of smoke covers much of eastern WA, with denser plumes closer to the above mentioned areas (partially obscured by upper level clouds). Forecast for eastern WA Winds will die down and allow smoke to start accumulating later today through Thursday morning. This could lead to areas of Very Unhealthy air in parts of Okanogan and Stevens Counties. Unhealthy conditions currently seen in Spokane are likely to improve slightly as winds turn northeasterly. Here's what the Canadian FireWork model is predicting for 2PM Wednesday (left) and 5AM Thursday:   Not expecting much clearing until late Thursday, but by then we might have smoke...

Rain this weekend! Bad news for fires.

Image
Good air quality has been sustained across the state for several days now thanks to some precipitation, cooler temperatures, and increased relative humidity.   Significant precipitation is expected this weekend too, which will further reduce any remaining fire activity.   Clear skies are expected next week but the summer weather is done for this year.  We are even starting to see some agricultural and prescribed burns in places, which indicates that the summer wildfire season is on its way out the door. Fire activity on the eastern slopes of the Cascades has been minimal. The light rain on Tuesday helped increase containment of fires like McLeod and Crescent Mountain . Some light s moke and fire activity will still be visible in parts of Okanogan County (e.g. Pasayten, Twisp) as stumps, downed logs, and other ground fuels continue to smolder.  Expect Good air quality for the next few days with some intermittent Moderate conditions immediately downwind of...
