MARINE LAYER STRATUS WITH PATCHY FOG WILL REOCCUR EACH NIGHT
THROUGH LATE NEXT WEEK. TEMPERATURES WILL VERY GRADUALLY COOL
OVER THE NEXT FEW DAYS BEFORE STABILIZING. EXPECT BELOW NORMAL
TEMPERATURES THROUGH LATE NEXT WEEK, TRENDING TOWARD NORMAL BY
NEXT WEEKEND. WINDS WILL REMAIN ELEVATED THROUGHOUT THE PERIOD
ACROSS THE ANTELOPE VALLEY AND FOOTHILLS, BUT WINDS WILL REMAIN
FAIRLY MILD ELSEWHERE.
SHORT TERM (TDY-TUE)
27/1228 PM.
TROUGHING OVER CA WELL INTO NEXT WEEK WILL MEAN A FAIRLY STABLE
FORECAST BETWEEN NOW AND THEN. ONSHORE FLOW AT THE SURFACE AND
DEEPENING OF THE MARINE LAYER WILL KEEP LOW STRATUS/FOG ALONG THE
COASTS AND COASTAL VALLEYS DURING THE EVENINGS AND MORNINGS/EARLY
AFTERNOONS.
WIND ADVISORIES REMAIN IN EFFECT THROUGH EARLY SUNDAY MORNING IN
THE ANTELOPE VALLEY AND WESTERN ANTELOPE VALLEY FOOTHILLS, AND
BEGINNING AT 5 PM PDT ACROSS THE SW SANTA BARBARA COAST AND THE
WESTERN SANTA YNEZ MOUNTAIN RANGE. SUSTAINED WINDS WILL RANGE 20
TO 30 MPH WITH GUSTS UP TO AROUND 50 MPH. WINDS HAVE BEEN LATE TO
REALIZE ACROSS THE ANTELOPE VALLEY, WITH GUSTS LARGELY BELOW
ADVISORY THRESHOLD STILL EARLY THIS MORNING. OFFSHORE SUNDOWNER
WINDS IN THE SANTA BARBARA ARE EXPECTED TO BE SLIGHTLY STRONGER
THIS EVENING THROUGH EARLY SUNDAY THAN THE PREVIOUS NIGHT AS THE
PRESSURE GRADIENT PEAKS.
ANOTHER LOW WILL DROP INTO NORTHERN CA ON MONDAY AND CONTINUE
ROTATING SOUTHWARD BEFORE LIFTING NORTHEASTWARD INTO NEVADA
TUESDAY. THIS WILL KEEP BELOW NORMAL TEMPERATURES IN THE FORECAST
THROUGH LATE NEXT WEEK. EXPECT DAYTIME HIGHS TO REMAIN MOSTLY
STABLE IN THE 70S AND LOW 80S IN THE VALLEYS, FAIRLY MILD WINDS
WITH GUSTS BELOW 15 TO 20 MPH OUTSIDE OF THE ANTELOPE VALLEY, AND
NO PRECIPITATION FORECAST WITH THE EXCEPTION OF THE POTENTIAL FOR
SOME LIGHT DRIZZLE TO FALL OUT OF THE LOW STRATUS DECK.
LONG TERM (WED-SAT)
27/1224 PM.
AFTER SEVERAL DAYS OF STABLE TEMPERATURES, ENSEMBLES INDICATE A
CHANGE IN THE UPPER-LEVEL PATTERN BY FRIDAY/SATURDAY OF NEXT WEEK
WHEN HIGH PRESSURE TAKES CONTROL OF OUR WEATHER PATTERN. THIS
MARKS A TRANSITION TO A GRADUAL WARMING TREND BEGINNING THURSDAY
AND NEAR-NORMAL TO SLIGHTLY ABOVE NORMAL TEMPERATURES DURING THE
HOLIDAY WEEKEND. THERE IS VARIATION AMONGST ENSEMBLES AS TO THE
STRENGTH OF HIGH PRESSURE, WHICH RESULTS IN SOME UNCERTAINTY WITH
REGARD TO HOW WARM OUR VALLEYS WILL GET DURING THE HOLIDAY. THE
NATIONAL BLEND OF MODELS INDICATES THE MOST WIDESPREAD HIGH
TEMPERATURES ON JULY 4TH BEING THE UPPER 70S AND 80S WITH FEWER
VALLEY AREAS WARMING INTO THE 90S.
