SALT LAKE CITY — It STILL smells like a wet campfire outside even after three days of rain, with smoke lingering over the Wasatch Front.
We hoped the storm would clean it out, but that might be because we are used to winter storms cleaning out winter inversions. This is different.
“It’s such an odd pattern,” said KSL Meteorologist Kevin Eubank.
It still smells like smoke and there’s more coming
He said in a cold air pool, the storm scours or vents the atmosphere.
“With smoke, because it comes in from the high levels, the rains actually pulled the smoke down and the concentration on the surface was even more intense,” said
The 24-48 hour forecast for smoke shows some thinning on Friday, but more smoke coming in on Saturday and Sunday.

“It comes in waves, and the only way to get rid of it is to put out the fires in California, Washington and Oregon that are producing all of that smoke,” said Eubank.
More smoke, more fires
There are also fires burning to the North West of us in British Columbia, Canada.
The National Weather Service posted a more detailed explanation on Twitter about how smoke and storms work together, and why the air quality and visibility appear so poor this week.
1/8 For those wondering why the mountains are no escape from the smoke these days… One key difference between our wintertime valley pollution and summertime smoke is the presence or lack of a stable layer in the form of a temperature inversion. #utwx pic.twitter.com/70mk6xl12h

The storm system brought the smoke with it for one thing. And for another, smoke from summer wildfires is different than winter inversion pollution.
