..DISCUSSION FROM MONTEREY
QUIET CONDITIONS INTO THIS WEEKEND WITH A COOLING TREND EXTENDING
INTO NEXT WEEK. NO MAJOR IMPACTS EXPECTED OUTSIDE OF BREEZY ONSHORE
DIURNAL WINDS EACH AFTERNOON; MAINLY AROUND FAVORED GAPS AND PASSES.
IMPROVING HUMIDITY THROUGH THE FORECAST PERIOD WITH A POTENTIAL
PATTERN CHANGE BRINGING IN EVEN DEEPER MOISTURE BY EARLY NEXT WEEK.
NOTE: ALL WINDS ARE 20-FOOT WINDS UNLESS OTHERWISE SPECIFIED.
THUNDERSTORMS IMPLY STRONG, GUSTY AND ERRATIC WINDS.
..DISCUSSION FROM LOS ANGELES/OXNARD
THE MONSOONAL MOISTURE AND INSTABILITY CONTINUE TO DIMINISH ACROSS
OUR MOUNTAINS AND DESERTS, WITH THE THUNDERSTORM PROBABILITY ONLY
5 TO 15 PERCENT ACROSS THE SAN GABRIEL MOUNTAINS AND NORTHERN
VENTURA COUNTY MOUNTAINS. IF ANY STORMS WERE TO DEVELOP, THE MAIN
THREATS WOULD BE ISOLATED DRY LIGHTNING STRIKES AND GUSTY WINDS AS
MOISTURE REMAINS LIMITED.
AS THE UPPER LEVEL RIDGE OF HIGH PRESSURE CONTINUED TO WEAKEN AND
ONSHORE FLOW NEAR THE SURFACE GRADUALLY INCREASES, THERE WILL
CONTINUE TO BE A SLIGHT DOWNWARD TREND IN TEMPERATURES THE NEXT FEW
DAYS, BUT STILL VERY WARM ACROSS THE INTERIOR WITH TEMPERATURES WELL
INTO THE 90S. THE VERY WARM TEMPERATURES COMBINED WITH RESIDUAL
INSTABILITY WILL RESULT IN MODERATELY DEEP MIXING HEIGHTS BETWEEN
10,000 AND 13,000 FEET EACH AFTERNOON THROUGH SATURDAY. AS A RESULT,
THERE IS STILL AN ELEVATED RISK FOR LARGE PLUME DOMINATED FIRES
ACROSS THE INTERIOR.
WITH A DRYING AIR MASS, THE HUMIDITY LEVELS WILL TREND DOWN THE NEXT
FEW DAYS, WITH MINIMUMS BETWEEN 10 AND 20 PERCENT BECOMING COMMON BY
FRIDAY AND SATURDAY. TYPICAL DIURNAL WINDS ARE ANTICIPATED FOR THE
NEXT SEVERAL DAYS, EXCEPT FOR SUNDOWNER WINDS FOR SOUTHWESTERN SANTA
BARBARA COUNTY DURING THE EVENINGS (NORTHWEST 15 TO 25 MPH WITH GUST
TO 35 MPH).
