DISCUSSION
SOMEWHAT GUSTY WINDS THIS MORNING ARE EXPECTED TO DIMINISH
THROUGH THE AFTERNOON. WIND DIRECTION WILL PRIMARILY BE FROM
THE NORTH-NORTHWEST, BUT COULD VARY BASED ON LOCAL TERRAIN
EFFECTS. WINDS MAY ALSO BECOME MORE VARIABLE IN DIRECTION AS
THE SPEEDS DROP OFF LATE THIS AFTERNOON. THE RELATIVELY LIGHT
WIND SPEEDS AND MIXING HEIGHTS BELOW 5000 FT AGL WILL LEAD TO
FAIR TO GOOD SMOKE DISPERSAL.
