DISCUSSION
SOUNDING LIKE A BROKEN RECORD FROM THE PREVIOUS DAYS THIS WEEK,
DENSE FOG CONTINUES TO BE A WEATHER CONCERN AND TRAVEL HAZARD
THIS MORNING WITH A DENSE FOG ADVISORY REMAINING IN EFFECT UNTIL
AT LEAST 11 AM. ONCE AGAIN, OBSERVATIONS, SATELLITE, AND
TRAFFIC CAMERAS WILL CONTINUE TO BE MONITORED AND AN EXTENSION
WILL BE POSSIBLE PENDING THOSE ANALYSES. A GRADUAL CLEARING IS
EXPECTED INTO THE LATER AFTERNOON, BUT DENSE FOG RISK ONCE AGAIN
RETURNS THIS EVENING AND INTO TOMORROW MORNING. WE CONTINUE TO
HIGHLIGHT HIGH TO VERY HIGH RISK CATEGORIES ON THE FOG SEVERITY
INDEX FOR THIS CONTINUED FOG THREAT. WIDESPREAD DENSE FOG, WITH
SOME VISIBILITIES DOWN TO A COUPLE TO A FEW HUNDRED FEET
CONTINUE TO BE PROBABLE GIVEN THIS STAGNANT PATTERN WE ARE IN.
FOGGY CONDITIONS WILL LIKELY CONTINUE UNTIL A PATTERN CHANGE
OCCURS, HOWEVER, THAT DOES NOT LOOK LIKE TO BE THE CASE
UNTIL AT LEAST LATE NEXT WEEK WHERE RIDGING MAY FINALLY BEGIN TO
BREAK DOWN. THOUGH CONFIDENCE IN THAT OCCURING AT THIS TIME IS
LOW. NEVERTHELESS, EXPECT SIMILAR CONDITIONS THROUGH MUCH OF THE
FORECAST PERIOD.
ASIDE FROM THE DENSE FOG, TEMPERATURES CONTINUE TO BE MILD AND
WARM DURING THE AFTERNOONS WITH HIGH TEMEPRATURES IN THE LOW TO
MID 60S IN THE VALLEY, AND NEAR 70S IN THE DESERT REGIONS.
COOLER TEMPERATURES ARE CERTAINLY EXPECTED IN THE HIGHER TERRAIN
AREAS, BUT STILL MILD FOR THIS TIME OF YEAR. TEMPERATURES AT
NIGHT REMAIN IN THE 40S ACROSS THE VALLEY, WITH TEMPERATURES IN
THE 30S TO SOME BELOW FREEZING IN THE DESERT AND HIGHER TERRAIN.
BREEZY CONDITIONS OF 30-35 MPH EASTERLY WINDS WILL BE EXPECTED
DURING THE MORNING HOURS SATURDAY FOR MOUNTAIN PEAKS AND HIGHER
ELEVATION AREAS IN THE SIERRA NEVADA'S AND THE KERN COUNTY
MOUNTAINS.
AVIATION
LIFR AND IFR CONDITIONS CONTINUE AT TERMINAL SITES. SIMILAR TO
PREVIOUS MORNINGS, EXPECT THESE CONDITIONS TO LINGER THROUGH
AROUND 19-21Z BEFORE SEEING IMPROVEMENTS. LIFR AND IFR
CONDITIONS WILL ONCE AGAIN EMERGE THIS EVENING AND THROUGH
SATURDAY MORNING. EXPECT CONDITIONS TO DETERIORATE FROM 02-04Z
AS REFLECTED IN THE TAFS. THOSE CONDITIONS WILL CONTINUE THROUGH
THE END OF THE 18Z TAF PERIOD.
