VERY QUIET CONDITIONS SHOULD CONTINUE TODAY AND  
TOMORROW, WITH TEMPERATURES REACHING THE LOW 40S.  
SMOKE DISPERSAL WILL BE POOR THROUGH THE PERIOD WITH SHALLOW  
MIXING HEIGHTS AND LIGHT WINDS. AN APPROACHING STORM SYSTEM WILL  
BRING A CHANCE OF SNOW SHOWERS WEDNESDAY NIGHT INTO THURSDAY. SNOW  
ACCUMULATION LOOKS TO BE LIGHT WITH LESS THAN AN INCH EXPECTED.  
BETTER MIXING AND INCREASED WINDS OUT OF THE NORTHWEST SHOULD LEAD  
TO BETTER SMOKE DISPERSAL THURSDAY AFTERNOON.
