TL; DR: A low pressure trough concerning Northern Utah will bring light snowfall starting early Tuesday afternoon with more intense snowfall beginning Tuesday night lasting into Wednesday. A winter weather advisory is in effect from Jan. 3 – Jan. 6 from NWS. Temperatures in the valley on Thursday will increase turning any precipitation into rain, however the Wasatch resorts will continue to see snowfall. The chance of precipitation reduces after Thursday as a high-pressure ridge will budge its way into the region dropping the humidity.

The moisture band for this storm is headed from the pacific NW and will only impact Northern Utah with precipitation and snowfall. Temperatures are in the low to mid 20’s with a light wind from the WNW. Expect high winds with the incoming storm from the WNW.
