This Hazardous Weather Outlook is for the western two thirds of
Utah and southwest Wyoming.

.DAY ONE...Today and Tonight

Fog, locally dense, will remain in place along the Wasatch Front
as well as the Cache Valley, Bear Lake area, and I-80 corridor
west of Salt Lake City through the morning hours. Travelers
should anticipate visibilities lowering to below a quarter mile
at times. Ice crystals will also seed out of the fog, leading to
slick travel conditions along area roadways. This fog may burn off
or thin by early afternoon, but is expected to redevelop tonight.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Inversion conditions will continue through at least Friday.
Expect fog to persist across many of the lower northern valleys
through the end of the week. Urban haze and poor air quality will
also continue through Friday due to the strong and persistent
valley inversions across northern Utah.

The next real chance to scour out the fog and haze will come
Friday night through Saturday. A weather disturbance approaching
from the northwest, though generating minimal amounts of
precipitation, will bring enough wind and colder air aloft to
break down the inversions and push fog and haze out of the area.


Weather spotters are encouraged to report significant weather
conditions according to standard operating procedures.
