AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1029 PM PDT TUE SEP 6 2011

.DISCUSSION...AS OF 9:00 PM PDT TUESDAY...WIDESPREAD STRATUS
PERSISTS ALONG THE COAST THIS EVENING ACCOMPANIED BY A SHALLOW
800 FOOT MARINE LAYER. LOW CLOUDS AND PATCHY DENSE FOG ANTICIPATED
TO MAKE LITTLE PROGRESS INLAND OVERNIGHT AS A RESULT OF THE
SHALLOW MARINE INVERSION. AN EARLY BURN OFF OF THE STRATUS IS
ANTICIPATED WEDNESDAY MORNING.

WARM TEMPERATURES AND LOW HUMIDITY ARE ANTICIPATED AGAIN TOMORROW
UNDER THE INFLUENCE OF A WARM UPPER LEVEL RIDGE. WARM TEMPERATURES
WILL CONTINUE THROUGH THE SECOND HALF OF THE WEEK HOWEVER THEY
WILL BE ON THE DECLINE. COASTAL REGIONS WILL SEE THE MOST COOLING
AS A COOLER AIRMASS IS USHERED IN OVER THE REGION AND THE MARINE
LAYER DEEPENS ALLOWING STRATUS TO PENETRATE FARTHER INLAND. INLAND
TEMPERATURES WILL SEE ONLY SUBTLE CHANGES THROUGH THE SHORT TERM.
AN UPPER LEVEL LOW IS FORECAST TO CUT OFF OVER THE WESTERN U.S.
THIS WEEKEND LEADING TO A MORE SIGNIFICANT DROP IN TEMPERATURES
ACROSS THE DISTRICT.

FROM PREVIOUS DISCUSSION...THIS IS A LOW CONFIDENCE FORECAST AS
CLOSED UPPER LOWS ARE NEVER PREDICTABLE WITH HIGH CONFIDENCE.
WHAT IT IMPLIES IS THAT IT COULD BEGIN TO DRAW SOME SUB-TROPICAL
MOISTURE NORTHWARD FROM SOCAL. PROBABILITIES LOOK BETTER FOR
T-STORM AND SHOWER ACTIVITY OVER SOCAL BUT THE QUESTION IS HOW
MUCH OF THIS MOISTURE WILL BE DRAWN NORTHWARD TO OUR FORECAST
AREA? THIS IS MANY DAYS OUT AND THERE IS TOO LARGE OF A RISK TO
HANG MY HAT ON T-STORMS AT THIS POINT. THEREFORE IT IS BEST TO
JUST WATCH AND SEE HOW THE OVERALL SYNOPTIC PATTERN EVOLVES AND
WHETHER OR NOT THERE ARE ANY MODEL TRENDS TO GO ON. OTHERWISE IT'S
GOING TO BE JUST THE USUAL LATE SUMMER WEATHER REGIME ACROSS THE
REGION THIS WEEK.

&&

.AVIATION...AS OF 10:29 PM TUESDAY...A VERY SHALLOW MARINE LAYER
PERSISTS ALONG THE COAST AND FOG IS MOVING IN. MARINE LAYER DEPTH IS
AROUND 1000 FEET...THUS MAIN PROBLEM AREAS WILL BE MAINLY AROUND THE
MONTEREY BAY AND POSSIBLY NEAR SFO AND OAK.

VICINITY OF KSFO...VFR CONDITIONS EXPECTED THROUGH THE EVENING
AND MOST OF THE NIGHT. LIFR CIGS AND IFR VIS POSSIBLE AGAIN THROUGH
THE SF BAY AFTER MIDNIGHT THROUGH MID-MORNING.

KSFO BRIDGE APPROACH...SIMILAR TO KSFO.

MONTEREY BAY AREA TERMINALS...LIFR CIGS AND VIS EXPECTED TONIGHT
THROUGH MID-MORNING WEDNESDAY.
