JACKSON, Wyo. — On winter mornings, a blanket of clouds hovering over the Jackson Hole Valley is a sure sign of a temperature inversion: when the air in the valley is colder than the air above it.
This phenomenon occurs because cold air is denser than warm air and therefore it sinks and fills in lower elevation areas.
Often a sight seen from Teton Pass or the Jackson Hole Tram, inversions make for a dramatic view at higher elevations.
According to Buckrail Meteorologist Alan Smith, a temperature inversion set in today as warmer air aloft moved in with the freezing level. It will reach 9,000-10,000 feet this afternoon. This inversion will likely keep valley high temperatures in the 20s throughout the day.
