AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
209 PM PDT WED MAR 30 2016

.SYNOPSIS...A GRADUAL WARMING TREND WILL PERSIST, ESPECIALLY
INLAND, THROUGH SATURDAY AS HIGH PRESSURE BUILDS ALONG THE WEST
COAST. A WEAK STORM SYSTEM WILL THEN PUSH INLAND TO OUR NORTH AND
MAY RESULT IN LIGHT PRECIPITATION OVER THE NORTH BAY ON MONDAY
ALONG WITH SLIGHTLY COOLER TEMPERATURES REGION-WIDE. DRY
CONDITIONS LIKELY RETURN AND TEMPERATURES REBOUND BY THE MIDDLE OF
NEXT WEEK.

&&

.DISCUSSION...AS OF 02:09 PM PDT WEDNESDAY...A COOL AND DRY AIR
MASS REMAINS ALOFT AS A BROAD MID/UPPER LEVEL TROUGH CONTINUES TO
STRETCH ACROSS MUCH OF THE SOUTHWESTERN PORTION OF THE COUNTRY.
MEANWHILE, MOISTURE IN THE BOUNDARY LAYER CONTINUES TO INCREASE
AND WILL LIKELY RESULT IN INCREASED COVERAGE OF LOW LEVEL CLOUDS
OVERNIGHT INTO THURSDAY MORNING. IN ADDITION, THE LATEST SHORT-
TERM FORECAST MODELS SHOW THE POSSIBILITY OF PATCHY FOG AND
DRIZZLE ALONG THE COAST EARLY THURSDAY MORNING WITH FOG EXTENDED
NORTHWARD INTO THE NORTH BAY VALLEYS.

A SLIGHT WARMING TREND WILL CONTINUE THROUGH THE REMAINDER OF THE
WEEK AS THE AFOREMENTIONED TROUGH SHIFTS AWAY FROM THE WEST COAST
AND HIGH PRESSURE BUILDS OVER THE EASTERN PACIFIC. WHILE INLAND
TEMPERATURES WILL BE WARMER AS THE AIR MASS ALOFT WARMS, THE
MARINE INFLUENCE WILL KEEP COOLER CONDITIONS NEAR THE COAST WITH
OVERNIGHT/EARLY MORNING STRATUS POSSIBLE THROUGH AT LEAST LATE
WEEK.

THE UPPER LEVEL RIDGE IS THEN FORECAST TO FLATTEN LATE IN THE
UPCOMING WEEKEND AHEAD OF AN APPROACHING MID/UPPER LEVEL TROUGH.
THIS SYSTEM IS CURRENTLY FORECAST TO PUSH INLAND TO OUR NORTH AND
MAY RESULT IN LIGHT PRECIPITATION OVER THE NORTH BAY ON MONDAY.
WHILE THE BEST MOISTURE AND UPPER LEVEL SUPPORT APPEARS TO BE
NORTH OF THE REGION, THE 12Z RUNS OF THE GFS AND CANADIAN MODEL
ARE NOW SHOWING RAINFALL AMOUNTS OF AROUND 0.05" TO 0.20" ACROSS A
GOOD PORTION OF THE REGION. MEANWHILE, THE ECMWF SHOWS A
DISSIPATING FRONTAL BOUNDARY WITH NO MEASURABLE RAINFALL FROM THIS
SYSTEM ON MONDAY. WILL KEEP AN EYE ON THE LATEST FORECAST TRENDS
IN THE COMING DAYS AND ADJUST THE FORECAST ACCORDINGLY.

DRY CONDITIONS AND WARMER DAYTIME TEMPERATURES WILL LIKELY RETURN
TUESDAY INTO WEDNESDAY AS THE MONDAY SYSTEM SHIFTS INLAND AND IS
REPLACED BY A BUILDING MID/UPPER LEVEL RIDGE.

&&

.AVIATION...AS OF 10:25 AM PDT WEDNESDAY...ANY LINGERING CLOUDS
WILL CONTINUE TO ERODE THROUGH 18Z. FORECASTING VFR THIS AFTERNOON
WITH LIGHT TO MODERATE WINDS. ONSHORE FLOW REMAINS TONIGHT WITH A
RETURN OF STRATUS...POSSIBLY MORE WIDESPREAD THAN THIS MORNING.
SOME OF THE MODEL GUIDANCE EVEN SUGGESTS DRIZZLE LATE TONIGHT.

VICINITY OF KSFO...VFR TODAY. A FEW LINGERING CLOUDS POSSIBLE OVER
THE EAST BAY AND NORTH OF SFO THROUGH 18Z. WILL BRING MVFR CIGS
BACK IN TONIGHT AFTER 06Z THROUGH 17-18Z THURSDAY.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY TERMINALS...VFR TODAY. MVFR TO POSS IFR CIGS RETURN
EARLY THIS EVENING.

&&

.MARINE...AS OF 10:22 AM PDT WEDNESDAY...LIGHT TO MODERATE
NORTHERLY WINDS WILL PREVAIL ALONG THE CENTRAL COAST THROUGH
FRIDAY. A LONGER PERIOD SOUTHERLY SWELL WILL ENTER THE COASTAL
WATERS WEDNESDAY AND WEDNESDAY NIGHT. A LONGER PERIOD
NORTHWESTERLY SWELL ENTERS THE COASTAL WATERS THURSDAY.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
     .TNGT...NONE.
