New fires in eastern WA. Prescribed burning likely

The Rock Creek fire on SR410 near Cliffdale is causing Moderate air around Naches. Expect air quality to vary between Moderate and Unhealthy for Sensitive Groups overnight in Naches, Yakima, Tieton and Cowiche, with daytime clearing through Friday. The Kittitas valley could see a little overnight smoke from this fire after Wednesday. 

In the lower Colombia Gorge, two fires are burning light fuels near Roosevelt. Areas from Wishram to Lyle will see a some smoke settling overnight, leading to ModerateUnhealthy for Sensitive Groups air.

It should be noted that several prescribed burns are planned throughout the Okanogan-Wenatchee National Forest in the coming days and weeks, and the public may see smoke as a result. 

Northeast winds blowing across the state will slacken early Wednesday, meaning colder overnight temperatures, calmer winds, and higher relative humidities, aiding fire fighting efforts. We should have less and less smoke as the week wraps up.

Here's a snapshot of the statewide forecast for Wednesday
