Nevertheless, evidence of a weak front moving over the Salt Lake Valley can be seen in the meteograms at the Salt Lake City airport overnight. Note how winds shift from southeasterly to northwesterly from about 2300 to 0100 MDT. Without larger-scale forcing, the preferred flow direction at the airport overnight is southeasterly, so northwest flow is a dead give away that something is up.
I'm no expert in this area, but I'm guessing that the front took one look into Utah County, saw the Y on the hill, and decided it was better off hanging around the U than to spending time today at BYU.
Forecasts for today show a somewhat disorganized pattern with the front weakening and another push of colder air moving into the state later in the day. The HRRR forecast for 0000 UTC (1800 MDT), for example, shows strong southerly flow pushing into southern Salt Lake County, where it meets an apparent lake breeze or perhaps remnants of last night's front. A stronger windshift lies over the northwest corner of Utah.
