AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
635 PM PDT TUE JUL 21 2015

.SYNOPSIS...LINGERING MID-LEVEL MOISTURE OVER THE SOUTHEASTERN
PORTION OF THE REGION HAS THE POTENTIAL TO RESULT IN AN ISOLATED
SHOWER OR THUNDERSTORM THROUGH THIS EVENING. OTHERWISE...TYPICAL
JULY WEATHER CONDITIONS WILL PERSIST THROUGH THE UPCOMING WEEKEND
ALONG WITH TEMPERATURES ON THE COOL SIDE OF NORMAL.

&&

.DISCUSSION...AS OF 02:39 PM PDT TUESDAY...REMNANT MOISTURE OVER
THE REGION HAS ALLOWED FOR CU DEVELOPMENT THIS AFTERNOON OVER
SOUTHERN MONTEREY AND SAN BENITO COUNTIES. THIS IS WHERE WE WILL
CONTINUE TO CARRY A SLIGHT CHANCE OF CONVECTION THROUGH THE
EVENING HOURS. OTHERWISE...THE MARINE LAYER THAT RETURNED
OVERNIGHT HAS KEPT MOSTLY CLOUDY CONDITIONS ALONG MANY COASTAL
AREAS WHERE TEMPERATURES HAVE BEEN A GOOD 10 DEGREES COOLER
COMPARED TO YESTERDAY.

A MARINE LAYER OF AROUND 1500 FEET WILL PERSIST THROUGH AT LEAST
MIDWEEK AND RESULT IN OVERNIGHT COASTAL CLOUDS...PATCHY FOG AND
POSSIBLE COASTAL DRIZZLE. HOWEVER...CHANCES FOR CONVECTION DIMINISH
TONIGHT AS A MID/UPPER LEVEL TROUGH APPROACHES FROM THE NORTH. THIS
WILL HELP DRY OUT MID-LEVEL MOISTURE AND...OUTSIDE OF THE COASTAL
DRIZZLE...MOST AREAS WILL REMAIN DRY THROUGH THE REMAINDER OF THE
WEEK. TEMPERATURES WILL REMAIN ON THE COOL SIDE OF NORMAL THROUGH
THURSDAY AS THE AFOREMENTIONED TROUGH SWINGS ACROSS CENTRAL
CALIFORNIA.

THE FORECAST MODELS GENERALLY AGREE THAT THE UPPER LEVEL WILL SHIFT
TO OUR EAST FRIDAY INTO SATURDAY WITH ZONAL FLOW DEVELOPING ALOFT.
INLAND TEMPERATURES WILL SLOWLY REBOUND TO NEAR SEASONAL AVERAGES
WITH ONGOING DRY CONDITIONS INTO EARLY NEXT WEEK.

&&

.AVIATION...AS OF 6:20 PM PDT TUESDAY...THE MARINE INVERSION IS
BASED BETWEEN 1700 AND 1800 FEET. THE SFO-SAC GRADIENT IS STRONG
AT 4.7 MB AND THE ACV-SFO GRADIENT IS 2.4 MB. ONSHORE WINDS WILL
CONTINUE TO USHER STRATUS AND FOG INLAND TONIGHT. THE MARINE LAYER
MAY BE DEEP ENOUGH TO PRODUCE PATCHY DRIZZLE AT THE IMMEDIATE
COAST LATE.

LATE AFTERNOON INSTABILITY WELL INLAND OVER THE SOUTHERN FORECAST
AREA LED TO A T-STORM WITH ECHO TOPS TO 40 THOUSAND FEET OVER SE
SAN BENITO COUNTY. SURFACE BASED INSTABILITY WILL DIMINISH BUT
MARGINAL MID LEVEL INSTABILITY HANGS AROUND IN THE SOUTHERN AREA
OVERNIGHT AND A SEPERATE AREA OF MID LEVEL INSTABILITY ORIENTED
NE-SW STRETCHES FROM NAPA COUNTY TO SAN MATEO COUNTY EARLY WEDNESDAY
...09Z-12Z. THIS COULD BE ENOUGH FOR A FEW ISOLATED SHOWERS
LATE...MUCH LESS CERTAIN ABOUT POSSIBLE ISOLATED LIGHTNING STRIKES.
LATE NIGHT ISOLATED SHOWERY WEATHER NOT PRESENTLY IN THE GRIDS OR
00Z TAFS...BUT MAY BE CONSIDERED WITH AN EVENING UPDATE.

VICINITY OF KSFO...WESTERLY WIND GUSTS TO 25 KNOTS IS HELPING TO
USHER IN THE STRATUS EARLY THIS EVENING. WESTERLY WINDS WILL
GRADUALLY SETTLE BELOW 20 KNOTS BEGINNING 04Z. MVFR CIGS TRANSTION
TO IFR BEGINNING 08Z.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...MVFR CIGS FOLLOWED BY IFR CIGS
BEGINNING 04Z. CLEARING RETURNS BY LATE WEDNESDAY MORNING.

&&

.MARINE...AS OF 02:39 PM PDT TUESDAY...HIGH PRESSURE WILL REMAIN
OFF THE PACIFIC NORTHWEST COAST THROUGH FRIDAY. THIS WILL KEEP
MODERATE NORTHWEST WINDS ACROSS THE COASTAL WATERS WITH THE
STRONGEST WINDS OVER THE NORTHERN WATERS.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .TNGT...SCA...PT ARENA TO PIGEON PT 10-60 NM
             SCA...PT ARENA TO PT REYES 0-10 NM UNTIL 3 AM
