Sunday Night-Wednesday:

Two shortwave troughs will move through Utah this week and bring 4-12″ of snow to most of Utah’s mountains through Wednesday.

Snow will get going Sunday night as the first shortwave moves into the state.

This will be associated with the cold front pushing from north to south.

Snow will fall apart a bit over the northern Wasatch before redeveloping over the central Wasatch and central Utah.

Snow will continue through Monday with the first shortwave before moving east out of the region. 

The second shortwave will close off into a cutoff low and redevelop snow over southern and central Utah.

Snow will then continue through Tuesday and Wednesday before tapering off Wednesday night as the shortwave slowly pushes east.

Winter Weather Advisories have been issued in anticipation of this.
