WILL ALSO ALLOW SOME MIXING TO OCCUR AFTER 1 PM CREATING VERY GOOD
SMOKE DISPERSAL THROUGH ABOUT 5 PM WHEN A QUICK RETURN TO POOR
DISPERSAL IS EXPECTED. SIMILAR CONDITIONS ARE EXPECTED AGAIN
THURSDAY THOUGH WITHOUT SNOW...AS GOOD MIXING WILL AGAIN CREATE
VERY GOOD SMOKE DISPERSAL FROM 1 PM TO 5 PM.
