With upper level transport winds continuing to bring smoke into Colorado from fires in the Pacific Northwest, we do anticipate that there will be an increase in particle pollution for much of the state over the weekend. For Saturday, it appears that the biggest impacts will be in northwestern and west-central parts of the state, so we are giving the heads up to folks in Craig, Meeker, Grand Junction, Rifle, Aspen, and surrounding areas. Although smoke concentrations are not anticipated to reach advisory levels, it's not completely out of the question so stay tuned to this space throughout the weekend.
It's likely that smoke will begin to increase in these impacted areas late Saturday morning and continue through the afternoon as the air mass at the earth's surface warms up and taps into the smoke that will be aloft. So if you are planning some strenuous outdoor activities on Saturday in northwestern or west-central Colorado, the earlier the better.
We are still monitoring the situation for Sunday/Monday as we could see an influx of additional smoke from fires in Canada. More on that as the situation evolves.
