..DISCUSSION FROM SFOFWFMTR
COOL CONDITIONS AND ONSHORE WINDS PREVAIL AS A DEEPENING TROUGH
APPROACHES THE REGION. CHANCES FOR RAIN ARRIVE LATE TUESDAY WITH
SHOWERS ACROSS MOST OF THE REGION THROUGH THURSDAY. WETTING RAINS
ARE EXPECTED ACROSS THE CENTRAL COAST WITH A SLIGHT CHANCE FOR
THUNDERSTORMS LATE TUESDAY NIGHT INTO WEDNESDAY. ACROSS THE SF BAY
AREA, CHANCES FOR WETTING RAINS ARE INCREASING, MAINLY ACROSS THE
HIGHER ELEVATIONS.
..DISCUSSION FROM SFOFWFEKA
AN AREA OF LOW PRESSURE WILL SLIDE SOUTH JUST OFF THE NORTHWEST
CALIFORNIA COAST THROUGH MONDAY NIGHT. A FEW LIGHT SHOWERS WILL BE
POSSIBLE BUT WETTING RAINS ARE UNLIKELY THROUGH TUESDAY. BETTER
CHANCES (30-40%) FOR WETTING RAINS WILL EXIST WEDNESDAY INTO
THURSDAY IN TRINITY, LAKE, AND SOUTHERN AND EASTERN MENDOCINO
COUNTIES AS MOISTURE MOVES INTO THE AREA ON THE NORTH AND EAST SIDE
OF THE LOW AS IT MOVES EAST-NORTHEAST OUT OF THE STATE. THE LOW
WILL DELIVER SOME INSTABILITY TO THE REGION WEDNESDAY, INCREASING
MIXING HEIGHTS AND BRINGING A LOW (8 TO 10%) CHANCE FOR
THUNDERSTORMS FOR EASTERN TRINITY COUNTY AND SOUTHWARD.
