AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
1045 PM PDT THU JUN 28 2012

.DISCUSSION...AS OF 8:59 PM PDT THURSDAY...STRATUS HAS FILLED IN
ALONG THE COAST THIS EVENING AND HAS BEGUN TO INTRUDE INLAND THROUGH
COASTAL GAPS AND VALLEYS. AN APPROACHING TROUGH SITUATED OFF THE
CALIFORNIA COAST WILL DEEPEN THE MARINE LAYER OVERNIGHT TO BETWEEN
1200 AND 1500 FEET. BOTH THE FORT ORD PROFILER AND BODEGA BAY
PROFILER PRESENTLY DEPICT THE MARINE LAYER TO BE AROUND 1200
FEET. THE TROUGH WILL ALSO CONTINUE TO STRENGTHEN THE ONSHORE
GRADIENT WHICH CURRENTLY STANDS AT NEARLY 7 MB FROM SFO-WMC AND
NEARLY 4 MB FROM SFO-SAC. THE DEEPER MARINE LAYER AND TIGHTER
ONSHORE GRADIENT WILL RESULT IN A DECENT ONSHORE PUSH OF THE
STRATUS OVERNIGHT AND INTO THE MORNING HOURS. TEMPERATURES ACROSS
THE REGION WILL DROP ON AVERAGE 5 DEGREES ON FRIDAY AS A RESULT OF
THE MORNING OVERCAST AND INLAND PUSH OF MARINE AIR. THE MARINE
LAYER WILL LIKELY DEEPEN FURTHER OVER THE WEEKEND AS A SLIGHTLY
DEEPER TROUGH MOVES ACROSS THE REGION. THE ONSHORE GRADIENT WILL
REMAIN MODERATELY STRONG AND NIGHT AND MORNING LOW CLOUDS WILL
PERSIST. TEMPERATURES WILL COOL SLIGHTLY THROUGH THE WEEKEND THEN
REBOUND EARLY NEXT WEEK AS HIGH PRESSURE BUILDS OVER THE EASTERN
PACIFIC. ALTHOUGH WE WILL SEE A SLIGHT WARMING TREND EARLY NEXT
WEEK TEMPERATURES WILL REMAIN SLIGHTLY BELOW NORMAL FOR THIS TIME
OF YEAR. MODELS ARE IN FAIRLY GOOD AGREEMENT AND THE FORECAST
REMAINS ON TRACK. NO UPDATED REQUIRED THIS EVENING.

&&

.AVIATION...AS OF 10:45 PM PDT THURSDAY...SURFACE GRADIENTS ARE
TRENDING MORE STRONGLY ONSHORE AND AN APPROACHING SHORTWAVE TROUGH
ALOFT WILL ENHANCE ONSHORE PUSH OVERNIGHT INTO FRIDAY.
THEREFORE...EXPECT LOW CIGS TO BECOME WIDESPREAD OVERNIGHT AND
REMAIN AT MOST TERMINALS UNTIL LATE MORNING OR EARLY AFTERNOON
FRIDAY. EARLY RETURN OF LOW CLOUDS EXPECTED AGAIN ON FRIDAY
EVENING.

VICINITY OF KSFO...IFR CIGS OVERNIGHT. CIGS MAY LIFT TO MVFR
AROUND MID MORNING ON FRIDAY BUT CLEARING NOT EXPECTED UNTIL ABOUT
