Smoke from wildfires out west to create more haze in our sky next few days

Temperatures continue to rise despite an increase in haze through at least Wednesday

Wildfire smoke from out west to create more haze through at least Wednesday

ROANOKE, Va. – The drought and extreme heat in western Canada and the Pacific Northwest has led to a number of large wildfires. As smoke from these fires gets lofted up, the jet stream can carry it to different places in the U.S. The west/northwest winds at airplane level have made it possible for that smoke to arrive in Virginia.

Even though most of it is suspended thousands of feet above the surface, the air quality Tuesday may pose an issue to those who are usually sensitive to changes in air quality. The most noticeable thing through at least Wednesday will be an increased amount of haze.

Wednesday will be a little hotter, thanks to a breeze coming down the mountains. That breeze will remain intact for the rest of the week, thanks to another front moving in from the north. In addition to the breeze, expect humidity levels to drop a little more by Thursday and Friday.
