UPDATE
AIR QUALITY ISSUES UPDATED.
KEY MESSAGES
1. DENSE FOG IN THE VALLEY IS EXPECTED FOR THE NEXT SEVERAL DAYS.
2. SLIGHT CHANCE OF SNOW ABOVE 7,000 FEET IN THE SIERRA NEVADA
THURSDAY AND FRIDAY. OTHERWISE, DRY CONDITIONS WILL PREVAIL FOR THE
WEEK.
DISCUSSION
THE FOG IS SLOW LIFTING THIS MORNING AS A CUTOFF LOW SPINS OFF
THE COAST OF CALIFORNIA. MODEL ENSEMBLES CONTINUE TO FAVOR THIS
LOW TO SLIDE INTO OUR AREA LATE TONIGHT THROUGH FRIDAY. HOWEVER,
THE WINDS IN THE VALLEY WILL REMAIN LIGHT AND DIURNAL EVEN WITH
THIS LOW WHICH WILL KEEP THE POTENTIAL FOR FOG INTO THE WEEKEND.
THIS SYSTEM IS NOT EXPECTED TO BRING RAIN TO THE VALLEY AS THERE
IS A 10 PERCENT CHANCE OR LESS OF ANY RAIN FOR MOST LOCATIONS
EXCEPT FOR BAKERSFIELD WHICH HAS A 20 PERCENT CHANCE. IN THE
SIERRA NEVADA, THERE IS A 55 TO 75 PERCENT CHANCE OF AT LEAST A
TRACE OF SNOW ABOVE 7,000 FEET THROUGH FRIDAY WITH THIS SYSTEM.
HIGHER PROBABILITIES OF A TRACE OF SNOW IS SEEN IN THE TULARE
COUNTY PORTION OF THE SIERRA NEVADA.
AFTER THE LOW SLIDES OUT FRIDAY, A WEAK RIDGE SLOWLY SLIDES IN
PROVIDING ENOUGH STABILITY THAT THE POTENTIAL FOR FOG WILL BE
HIGHER. THE CPC HAVE A 60 TO 70 PERCENT CHANCE OF ABOVE AVERAGE
TEMPERATURES IN BOTH ITS 6-10 AND 8-14 DAY OUTLOOKS. THE CPC
ALSO HINTS AT A PATTERN CHANGE FROM BEING 40 TO 50 PERCENT
CHANCE OF BELOW AVERAGE PRECIPITATION IN THE 6-10 DAY OUTLOOK TO
BEING NEAR NORMAL IN THE 8-14 DAY OUTLOOK.
AVIATION
MVFR TO IFR CONDITIONS CONTINUE AT MANY LOCATIONS IN THE CENTRAL
VALLEY DUE TO SOME LINGERING BR AND LOWERED CIGS. CONDITIONS
SHOULD CONTINUE TO GENERALLY IMPROVE, WITH SOME VFR CONDITIONS
POSSIBLE IN SPOTS DURING THE REST OF THE AFTERNOON. INTO
TONIGHT, IFR AND LIFR CONDITIONS WILL ONCE AGAIN DEVELOP FROM
AREAS OF FOG AND LOW CIGS DURING THE LATE EVENING AND INTO
THURSDAY. CURRENT THINKING IS FOG IS NOT AS WIDESPREAD DENSE AS
PREVIOUS DAYS, BUT STILL EXPECT THAT FOG TO BE AROUND THE AREA.
