CONDITIONS WEDNESDAY WILL BE SIMILAR TO THOSE EARLY WEEK.
CALM NIGHTTIME WINDS WILL DEVELOP INTO AFTERNOON NW LIGHT WINDS WITH WEAK
GUSTS UP TO 15MPH. A WARMING TREND IS EXPECTED THROUGH THE LATER HALF
OF THE WEEK WITH TEMPERATURES REACHING UP TO MID TO HIGH 80S THROUGH
THE WEEKEND. THIS HEATING IS DUE TO AN INCOMING UPPER LEVEL RIDGE.
RIDGING WILL CREATE A DRIER AND MORE STABLE ATMOSPHERE, SO EXPECT SLIGHTLY
LOWER RH VALUES BOTH FOR DAYTIME AND NIGHTTIME. WINDS WILL ALSO BE WEAKER
THROUGH THIS TIME, INCREASING THE INFLUENCE OF SMOKE ON BURN OPERATIONS.
NO RAIN, DRIZZLE, OR LOW CLOUD COVERAGE IS EXPECTED THROUGH OCT 6.
