  24. 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.
