Warming up again; Air quality getting worse

Posted
and last updated

After being in a deep freeze the last couple days, it's finally starting to warm up!

High pressure building in from the west will keep it dry this week and help to gradually warm things up. Temperatures will climb faster in the mountains than in the valleys. As a result, inversions will develop and air quality will get worse. Try to limit your driving and not idle the car!

Inversions are expected to weaken this weekend.
