.DISCUSSION...Today is shaping up to be a better day for burning with
increasing winds out of the southwest. This will help drive good smoke
dispersion as mixing heights reach to nearly 6,000 feet. RHs drop with
warming temperatures allowing for better burning, but we are expecting
scattered high level cloud cover throughout the day.
