AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
458 AM PDT MON AUG 31 2015

.SYNOPSIS...GENERALLY DRY WEATHER CONDITIONS WILL PERSIST ACROSS THE
REGION THROUGH THE UPCOMING WORK WEEK. DAYTIME TEMPERATURES NEAR
THE COAST WILL CONTINUE TO BE NEAR NORMAL...WHILE INLAND AREAS
WILL BE SLIGHTLY BELOW SEASONAL AVERAGES.

&&

.DISCUSSION...AS OF 3:15 AM PDT MONDAY...A STRONG NORTHERLY
SURFACE FLOW THIS MORNING HAS HELPED TO KEEP VIRTUALLY OUR ENTIRE
AREA CLOUD FREE SO FAR. LAST FEW FRAMES SHOW ONE PATCH OF CLOUDS
OFF THE SAN MATEO COAST HEADING TO THE SOUTH. THIS AREA WILL
LIKELY EXPEND OVER THE NEXT FEW HOURS AND IMPACT AT LEAST SOUTHERN
MONTEREY BAY COASTLINE. OUTSIDE OF THAT...SHOULD BE A MOSTLY
SUNNY START TO THE DAY. TEMPS ARE RUNNING CLOSE TO WHERE WE WERE
YESTERDAY AND HIGHS ARE EXPECTED TO BE CLOSE TO THE VALUES WE HIT
ON SUNDAY. LOOK FOR UPPER 60S TO UPPER 70S AT THE COAST WITH UPPER
70S TO NEAR 90 FOR INLAND SPOTS. ONE DIFFERENCE FROM YESTERDAY IS
WINDS FOR THE AFTERNOON SHOULD BE SLIGHTLY LESS ALTHOUGH WE WILL
STILL SEE LOCAL GUSTS TO AROUND 30 MPH.

FOR THE REST OF THE WEEK QUIET WEATHER IS EXPECTED AS THE OVERALL
SYNOPTIC PATTERN HAS A LONGWAVE TROF OVER THE WESTERN THIRD OF THE
CONUS WHILE A RIDGE AXIS IS EXPECTED OVER THE EASTERN THIRD. THIS
WILL PRODUCE TEMPS AT OR A BIT COOLER THAN NORMAL INLAND WHILE
COASTAL SPOTS WILL BE AT OR SLIGHTLY ABOVE NORMAL DUE TO OFFSHORE
FLOW AND ABUNDANT SUNSHINE. THE STORM TRACK WILL REMAIN WELL TO
OUR NORTH.

FURTHER OUT...NO SIGN OF RAIN THROUGH AT LEAST THE MIDDLE OF NEXT
WEEK.
&&

.AVIATION...AS OF 4:55 AM PDT MONDAY...SURFACE HIGH PRESSURE OFF
THE CALIFORNIA COAST EXTENDS INTO THE OREGON COAST. THIS IS
PRODUCING A DRY NORTHERLY FLOW WHICH WILL KEEP THE SFO BAY AREA
FREE OF THE STRATUS TODAY. STRATUS ALONG THE SAN MATEO COAST WILL
SPREAD SOUTH INTO THE MRY BAY AREA BRINGING IFR CIGS TO MRY AND
POSSIBLY SNS EARLY THIS MORNING.

VICINITY OF KSFO...VFR. WEST WINDS GUSTING TO 25 KT AFTER 20Z.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...IFR CIGS AT MRY CLEARING 16Z OR
EARLIER. VFR EXPECTED AT SNS DUE TO THE PATCHY NATURE OF THE CIGS
BUT CANNOT RULE OUT THE POSSIBILITY OF BRIEF IFR CIGS 13Z-16Z.

&&

.MARINE...AS OF 03:05 AM PDT MONDAY...HIGH PRESSURE OFF THE
CALIFORNIA COAST EXTENDS INTO THE OREGON COAST. GUSTY NORTHWEST
WINDS WILL CONTINUE OVER THE COASTAL WATERS THROUGH TUESDAY. WINDS
WILL DECREASE LATE TUESDAY AS THE HIGH WEAKENS.
