Yesterday's cold-frontal passage probably brought more dust to the central Wasatch than snow. Frontal passage at the University of Utah featured the usual wind shift and temperature drop, but also a spike in PM2.5 associated with blowing dust.
Peak concentrations at the U reached almost 15 ug/m3, which equates to a moderate air quality level.
Cameras at the University of Utah caught the post-frontal dust and gravity-current-like nose of the cold front passing through the Salt Lake Valley.
And check out the terrain induced flows over western Nevada with dust from the Carson Sink providing a great tracer.
