..DISCUSSION FROM SFOFWFMTR
A WEAK UPPER LEVEL TROUGH HAS PRODUCED PATCHY LIGHT RAIN ACROSS
PORTIONS OF SONOMA COUNTY OVERNIGHT, PRIMARILY OVER THE COASTAL
RANGES WITH ONLY A FEW HUNDREDTHS OF AN INCH EXPECTED WHERE RAIN
DOES FALL, AND DECREASING CHANCES OF THUNDERSTORMS THAT WERE ALREADY
LOW. A ROBUST MARINE LAYER BETWEEN 2000-2500FT WILL PERSIST TODAY
INTO SATURDAY WITH BELOW NORMAL TEMPERATURES. A WARMING TREND BEGINS
ON SUNDAY AND PICKS UP MOMENTUM BY THE MIDDLE OF NEXT WEEK WITH
DRIER CONDITIONS AND A COMPRESSED MARINE LAYER EXPECTED TO REMAIN
CLOSER TO THE COASTLINE.
..DISCUSSION FROM SFOFWFEKA
HOT AND DRY CONDITIONS HAVE CONTINUED QUICKLY EASE TODAY WITH MOST
INTERIOR VALLEYS STRUGGLING TO REACH 80 AND RH RATCHETING UPWARD
CLOSER TO 30 PERCENT. CONDITIONS WILL FURTHER EASE THROUGH FRIDAY
WITH INCREASING MARINE INFLUENCE CLOSE TO SHORE. WINDS WILL MOSTLY
REMAIN MODERATE AND TERRAIN DRIVEN. THUNDERSTORMS CHANCES INCREASE
EARLY FRIDAY MORNING WITH STORMS MOST LIKELY TO FORM OVER HIGH
TERRAIN IN NORTHERN HUMBOLDT AND TRINITY COUNTIES EARLY IN THE
MORNING. UNCERTAINTY REMAINS HIGH (20% CHANCE OF STORMS), BUT ANY
STORMS THAT DO FORM WILL BE MOSTLY DRY AND FAST MOVING. ISOLATED
THUNDERSTORMS MAY ALSO DEVELOP IN NORTHEAST TRINITY COUNTY SATURDAY
AFTERNOON, AND POSSIBLY AGAIN TUESDAY.
