..DISCUSSION FROM SFOFWFMTR
ONSHORE WINDS, COOLER TEMPERATURES AND A DEEPENING MARINE LAYER
WILL PREVAIL THROUGH TONIGHT. THE MARINE LAYER WILL QUITE LIKELY
COMPLETELY MIX OUT BY LATER MONDAY. THE PATTERN WILL CONTINUE TO
COOL DURING THE WORK WEEK, WITH A LOW PRESSURE SYSTEM BRINGING
SHOWERS FOR MUCH OF THE REGION DURING MIDWEEK. THERE'S A SLIGHT
CHANCE OF WET THUNDERSTORMS OVER MONTEREY COUNTY LATE TUESDAY NIGHT
AND WEDNESDAY. WETTING RAINS ARE LIKELY FOR MUCH OF THE CENTRAL
COAST, WITH CHANCES INCREASING FOR THE BAY AREA.
..DISCUSSION FROM SFOFWFEKA
A FRONT ARRIVES LATE SUNDAY LEADING TO A PRONOUNCED COOLING AND
MOISTENING TREND. WESTERLY TO NORTHWESTERLY WINDS WILL TURN BREEZY
SUNDAY AFTERNOON, PARTICULARLY IN SOUTHERN MENDOCINO AND LAKE
COUNTY. STOUT OVERNIGHT RECOVERIES ARE EXPECTED FOR COASTAL RIVER
VALLEYS AS THE MARINE LAYER DEEPENS. A SLIGHT CHANCE OF VERY LIGHT
RAIN SHOWERS EXISTS FOR HUMBOLDT, DEL NORTE, TRINITY, AND WESTERN
MENDOCINO MONDAY NIGHT INTO TUESDAY. SOME INSTABILITY MAY ARRIVE
WITH A PASSING AREA OF LOW PRESSURE. THUNDERSTORM CHANCES ARE
CURRENTLY LOW, LESS THAN 10%, BUT THE THREAT MAY DEVELOP FOR THE
SOUTHERN REGION OVER LAKE AND MENDOCINO COUNTIES. THE LOW MAY TAP
INTO SOME SUBTROPICAL MOISTURE MID LATE IN T HE WEEK WHICH MAY
BRING MORE PRODUCTIVE SHOWERS OR SOME THUNDERSTORMS TO THE SOUTHERN
ZONES. COOLER AND UNSETTLED WEATHER IS EXPECTED THROUGH THE COMING
WORK WEEK AS THE LOW STALLS SOMEWHERE OFF THE CENTRAL .
