DISCUSSION
HIGH PRESSURE WILL REMAIN IN PLACE ACROSS THE AREA THROUGH THE
PERIOD. THIS WILL MEAN, MAINLY CLEAR SKIES ACROSS THE AREA. THIS,
ALONG WITH LIGHT AND VARIABLE WINDS WILL MAKE FOR RH VALUES
DROPPING BELOW 30% AT TIMES FOR THE NEXT 3 DAYS. THE ONLY CONCERN
OVER THE NEXT FEW DAYS WILL BE DUE TO LOW RH VALUES.
