In some instances, however, the cold pool is incredibly shallow. As such, it might be better labeled a cold puddle. One could observe lingering pollution in such a cold puddle yesterday afternoon over the Great Salt Lake and and lower elevations of the northern Salt Lake Valley.

What is happening here is that an extremely shallow puddle of cold air remained entrenched over the Great Salt Lake. That cold air eventually pushed southward and eastward into the Salt Lake Valley with the Great Salt Lake breeze yesterday afternoon. The temperature contrast accompanying the Great Salt Lake breeze was greatly concentrated thanks to the warm southerly flow ahead of it.
The Salt Lake City Airport and areas to the west can sometimes feel like another planet compared to the University of Utah and the east bench, and that was the case late yesterday afternoon.
