.DISCUSSION...

THE UPPER LEVEL LOW PRESSURE SYSTEM CURRENTLY OVER THE SOUTHEAST U.S.,
WILL CONTINUE TO MOVE OFF TO THE NORTHEAST TODAY. AS IT DOES,
SURFACE HIGH PRESSURE WILL BE BUILDING OVER SOUTH FLORIDA. THE
COMBINATION OF THE TWO WILL KEEP LIGHT AND VARIABLE WINDS WITH LOCAL SEA BREEZES.
IT WILL ALSO KEEP QUIET, DRY WEATHER IN THE FORECAST FOR THE
REMAINDER OF THE WEEK. THE RELATIVE HUMIDITY THIS AFTERNOON AT THE
FIRE SITE WILL LIKELY DROP BELOW 40 PERCENT BUT REMAIN ABOVE
CRITICAL THRESHOLDS. THE LOW LEVEL WIND WILL ALSO BECOME 5 TO 10
MPH AND THIS WILL ALLOW THE DISPERSION TO BEGIN POOR TO FAIR BUT
BECOME GENERALLY GOOD BY EARLY IN THE AFTERNOON.
