I suspected something about the weather had changed when I saw a fully cloudy sky this morning on my way to school, but I didn't expect snow today. I guess I should have paid better attention to the weather.
From the NWS in Salt Lake:

The radar shows this snow is widespread, and the camera display shows that as well.
Looks like this fun weather will stick around a few days...
This winter hasn't really felt like winter, so why the change?
Most of February we the Intermountain West has been the parking spot of a high pressure ridge. This kept our temperatures rather warm and skies clear. This is not the pattern that brings us snow.
Today, the ridge is off to our west, meaning a trough has backed up towards the west. This allows storms to come into Utah.
