..DISCUSSION FROM SFOFWFMTR
A DRY COLD FRONT WILL SLICE THROUGH THE BAY AREA AND CENTRAL COAST
DURING THE PRE-DAWN HOURS ON FRIDAY. THIS WILL TRANSLATE INTO AN
INCREASE IN NORTHERLY 20 FOOT WINDS TO AROUND 15 MPH AND LEAD TO
GOOD TO EXCELLENT MORNING HUMIDITY RECOVERY; MAINLY ACROSS THE NORTH
AND EAST BAY. FARTHER SOUTH, ACROSS THE DIABLO RANGE AND CENTRAL
COAST, RH RECOVERY WILL REMAIN POOR. MORNING HUMIDITY VALUES BETWEEN
30 AND 40 PERCENT ARE FORECAST. MAX RH TRENDS WILL IMPROVE THROUGH
SUNDAY MORNING AREA WIDE, THOUGH ACROSS THE SANTA LUCIA RANGE RH
RECOVERY WILL REMAIN MODERATE. THEREAFTER, A FEW BURSTS OF OFFSHORE
FLOW ARE ANTICIPATED. WHILE WIND GUSTS ABOVE 30 MPH MAY BE CONFINED
TO THE HIGHEST ELEVATIONS, THE PRIMARY FIRE WEATHER CONCERN WILL BE
THE POOR RH RECOVERY. THIS WILL BE ESPECIALLY TRUE ACROSS THE SANTA
LUCIA RANGE WHERE MAX HUMIDITY VALUES MAY STRUGGLE TO CLIMB ABOVE
30 PERCENT. OTHERWISE, DAILY AFTERNOON HUMIDITY WILL FALL DOWN TO
NEAR 20 PERCENT ACROSS THE INTERIOR.
..DISCUSSION FROM SFOFWFEKA
A LOW PRESSURE SYSTEM ARRIVING THIS EVENING INTO FRIDAY WILL BRING
COOLER TEMPERATURES ALONG WITH WETTING RAIN ACROSS DEL NORTE AND
NORTHERN HUMBOLDT COUNTIES, WHILE AREAS TO THE SOUTH REMAIN MOSTLY
DRY. BREEZY WEST-SOUTHWEST WINDS THIS AFTERNOON WILL BRING ELEVATED
FIRE WEATHER CONDITIONS IN LAKE, EASTERN MENDOCINO, AND TRINITY
COUNTIES THIS AFTERNOON. RELATIVE HUMIDITY WILL RISE FRIDAY, EVEN
IN AREAS THAT DO NOT RECEIVE RAIN. BREEZY WEST- NORTHWEST WINDS ARE
LIKELY AGAIN IN FRIDAY AFTERNOON IN THE INTERIOR. OFFSHORE FLOW
RETURNS DRIER AIR FRIDAY NIGHT INTO SATURDAY.
