.DISCUSSION...
HIGH PRESSURE REMAINS IN CONTROL TODAY AND TOMORROW. THIS WILL
KEEP THE WEATHER QUIET. IT WILL ALSO KEEP THE TRANSPORT WIND ON
THE LOW SIDE TODAY, RESULTING IN LOWER DISPERSIONS. UNDER THE
HIGH, THE GENERAL WIND WILL BE WEAK, ALLOWING FOR THE SEA BREEZE
TO BE MORE DOMINATE. THIS HAS CAUSED THE SOUTHWEST WIND TO DEVELOP
AT THE SURFACE, AND MAY MAKE THE WIND AT THE BURN SITE VARIABLE,
AS THE SEA BREEZE FROM BOTH COASTS MEET IN THE VICINITY. TONIGHT,
THE WIND WILL GO LIGHT AND VARIABLE. WHILE THE MODELS ARE CALLING
FOR A SOUTH WIND, THERE IS A SLIGHT CHANCE FOR THE DRAINAGE WIND
TO TAKE OVER. ALSO, THERE IS A POTENTIAL FOR FOG DEVELOPMENT IN
THE BURN AREA IN THE EARLY MORNING HOURS, WITH EVEN BETTER CHANCES
OF FOG FRIDAY NIGHT.
