This morning a passing cold front kicked up a lot of dust. This is the PM 2.5 concentration at the Mt. Met. Lab at the University of Utah.
A look at the NAA camera shows just how dusty it got. This morning was clear...
Then the dust blew in around 10:00 AM
Then you couldn't see the mountains
Looking at the MesoWest observations at 11:05 shows winds gusting in the 40s from the northwest. Pretty wild.
