DISCUSSION
WARM CONDITIONS AND MOSTLY LIGHT, MAINLY EAST AND SOUTHEAST WINDS
ARE EXPECTED OVER THE NEXT FEW DAYS. AFTERNOON MINIMUM RELATIVE
HUMIDITY VALUES ARE FORECAST TO BE BETWEEN 35-45% INLAND AND
CLOSER TO 50% CLOSER TO THE COAST. A DAILY RISK OF ISOLATED TO WIDELY
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE OVER THE NEXT SEVERAL DAYS.
WHILE PRE-DAWN FOG CAN'T BE RULED OUT ENTIRELY, IT SHOULD BE VERY
ISOLATED AND RESTRICTED TO KNOWN FOGGY SPOTS - LOW-LYING AND
USUALLY WITH THEIR OWN LOCAL SOURCE OF MOISTURE.
