Smokey Skies

 
Smokey Skies for eastern Utah and western Colorado

On Wednesday the subtropical ridge of high pressure, that has been around the region since early July,
was stretched from southern Oregon into southern New Mexico. Clockwise rotation around the ridge
is producing a northwest flow over eastern Utah and western Colorado this week. There are numerous
wildfires in northern California, southern Oregon, northern Nevada, and Idaho. The northwest flow aloft
is pulling smoke in to the region from these fires.

The forecast is for the ridge to remain in its current orientation through Friday, then amplify northward
over the Great Basin over the weekend. This will continue to allow smoke to drift over eastern Utah and
western Colorado into early next week.
