AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
415 PM PDT SAT AUG 30 2014

.SYNOPSIS...DRY WEATHER CONDITIONS WITH NEAR SEASONAL TEMPERATURES
WILL PERSIST THROUGH THE FIRST HALF OF THE UPCOMING WORK WEEK.
TEMPERATURES ARE THEN FORECAST TO COOL SLIGHTLY FOR THE LATTER HALF
OF THE WEEK AS AN UPPER LEVEL TROUGH IMPACTS THE REGION.

&&

.DISCUSSION...AS OF 02:15 PM PDT SATURDAY...WARM TEMPERATURES AND
FAIR WEATHER CONDITIONS PREVAIL ACROSS THE REGION THIS AFTERNOON
UNDER MOSTLY SUNNY SKIES. FEW/SCT HIGH CLOUDS STREAMING OVER THE
CENTRAL COAST ARE A RESULT OF MOISTURE ALOFT ASSOCIATED WITH THE
MID/UPPER LEVEL TROUGH THAT CONTINUES TO PUSH THROUGH THE WESTERN
CONUS.

WEAK RIDGING ALOFT WILL BUILD ACROSS THE EASTERN PACIFIC THROUGH
EARLY NEXT WEEK AS THE UPPER TROUGH PUSHES EASTWARD AND WILL RESULT
IN DRY WEATHER CONDITIONS AND TEMPERATURES AT OR SLIGHTLY ABOVE
SEASONAL AVERAGES. OVERNIGHT AND EARLY MORNING COASTAL CLOUDS WILL
ALSO BE LIKELY WITH PERSISTENT ONSHORE FLOW AND A MODEST MARINE
LAYER IN PLACE.

THE FORECAST MODELS ARE IN SOMEWHAT OF AN AGREEMENT IN BRINGING A
MID/UPPER LEVEL TROUGH AND/OR CLOSED LOW INTO NORTHERN CALIFORNIA
DURING THE LATTER HALF OF NEXT WEEK. DO SHOW A SLIGHT COOLING
TREND FOR THURSDAY AND FRIDAY AS 850MB TEMPERATURES DROP BY A FEW
DEGREES. OTHERWISE...THIS SYSTEM APPEARS TO BE DRY AND WILL KEEP
PRECIPITATION CHANCES AT ZERO THROUGH THE EXTENDED.

AFTERNOON FOLLOWING FAST BURN OFF THIS MORNING. STRATUS REDEVELOPMENT
