TL ; DR: The closed low over the southwest U.S. has merged with the strong vorticity max over the interior mountain west which will fuel continued mountain precipitation today into tonight. Mountain precipitation will continue through tonight into early Sunday. Once this system passes through, a ridge will build into our region.
Short Term:
A front has passed through this morning, with dropping dew points. Mixing from this system will help to remove any leftover pollution from the previous inversion this past week. Now that we are post frontal, we are seeing northwesterly flow at the surface, helping to advance orographic precipitation.
As the system continues to move eastward, precipitation in the valley will fizzle out by this afternoon and mountain precipitation will continue through the evening. The mountains are predicted to receive 1-5" of snow through the day today with up to 1" of SWE.
Long Term:
By late Sunday, the trailing ridge will build over Utah. This will bring more calm weather with highs in the mid 30s and lows near the 20s for the next few days. This ridge will persist through the week.
