The Importance of Geography  It doesn’t take much for mountains to get 12”+ snow events Wasatch Range/Uinta Mountains

The Snow Verification Mess  No CoCoRaHS…  Joe and Sally live in valleys…  Left to look at random ski resorts, SNOTEL, and few Mesonet obs  Speaking of SNOTEL…

Lessons Learned  Behind a cold front, there can be a “lag” in gusty winds  Four lows in the four corners!  The same storm system that brought mountains over a foot of snow, can bring nothing to places like the salt flats  Geography is REALLY important  Dense fog is difficult to verify given lack of obs.
