VERY QUIET CONDITIONS SHOULD CONTINUE TODAY AND
TOMORROW, WITH TEMPERATURES REACHING THE UPPER 30S TO 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

TO BETTER SMOKE DISPERSAL THURSDAY AFTERNOON.
