...REMARKS...HIGH PRESSURE WAS IN PLACE FOR MUCH OF THE MONTH. THIS
KEPT A THICK MARINE LAYER IN PLACE FOR MUCH OF THE MONTH. THEREFORE
FOG OR HEAVY FOG WAS REPORTED ON ALL BUT ONE DAY THIS MONTH ALTHOUGH
HAZE WAS RECORDED ON THAT ONE DAY (THE 20TH). SKIES WERE VERY SMOKY
AND ASH FELL ALMOST DAILY DUE TO NUMEROUS WILDLAND FIRES THROUGHOUT
NORTHERN CALIFORNIA. THE SMALL AMOUNT OF PRECIPITATION THAT DID FELL
CAME IN THE FORM OF DRIZZLE. NO RECORDS WERE REPORTED THIS MONTH.
