Area Forecast Discussion
National Weather Service San Francisco Bay Area
524 PM PDT TUE SEP 6 2016

.SYNOPSIS...A warming trend will continue today and peak on
Wednesday as high pressure builds over our region. Low clouds
will be limited and remain mostly confined to coastal areas
through midweek as well. Onshore flow will increase late in the
week as the high pressure weakens and allows for temperatures to
fall back to near seasonal averages.

&&

.DISCUSSION...as of 1:30 PM PDT Tuesday...As expected today has
turned out to be sunny across our entire region due to a moderate
northerly flow at the surface, a building ridge of high pressure,
and a marine layer that is virtually nil. Satellite does show some
clouds well to our west, however these are not forecast to return
for at least a couple of days.

Temperatures have been running ahead of yesterday at this time
with a few spots more than 10 degrees warmer. Even coastal spots
have seen a decent bump in numbers with many locations near
beaches in the mid 60s to mid 70s.

The ridge of high pressure will further build into our region for
tomorrow while 850 MB temps increase another degree or so. This
will help to produce some of the warmest highs we have had in a
long time -- especially at the coast. In some cases, Wednesday
will be the warmest since June (although we will generally be far
from any records) with beaches getting into the 70s to mid 80s.
Inland spots will see very warm to hot readings with widespread
upper 80s to around 100. A few of our warmest locations will soar
into the lower 100s.

Temperatures will slowly decrease starting on thursday as the
ridge flattens out and the surface flow begins to switch to more
onshore. Look for a 3 to 7 degree drop on Thursday and Friday
which will cool us back into the normal/slightly below normal
range. The marine layer will also start to rebuild with overnight
clouds and patchy fog expected at the coast and some adjacent
valley spots.

Longer range forecast continues the dry weather through the end of
next week.

&&

.AVIATION...as of 5:00 PM PDT Tuesday...For 00Z Tafs. Mainly clear
skies will prevail through the forecast period. Low clouds are
anticipated to return to the coast tonight with minimal intrusion
inland under a very shallow marine layer. Moderate west winds
expected through this evening with light and variable winds
overnight.

Vicinity of KSFO...VFR. Moderate onshore flow around 20 kt will
gradually ease this evening becoming light overnight.

High confidence.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals...VFR conditions through at least 04Z and
06z tonight for KSNS and KMRY respectively. LIFR to VLIFR
conditions expected again between 07Z and 16Z. VFR conditions will
return once the fog and low clouds clear around 16Z. Light to
moderate westerly winds becoming light and variable overnight.

&&

.FIRE WEATHER...as of 03:55 AM PDT Tuesday...The warming and
drying trend that got underway on Monday will continue today
before peaking Wednesday afternoon as high pressure builds over
the region. Temperatures above the compressed marine layer (around
500-800 feet in depth) are already much warmer compared to 24
hours ago based off of current observations. With this, do expect
relative humidity recoveries to be poor in the hills the next
couple of days. Mostly light northerly winds will persist and
become light offshore at times tonight through Wednesday. Winds
are then expected to become light and variable to light southerly
Wednesday night and Thursday. As the ridge aloft weakens late in
the week, onshore flow will increase, temperatures will cool and
the marine layer is forecast to deepen slightly through the
upcoming weekend.

&&

.MARINE...as of 1:43 PM PDT Tuesday...Not much to update from
last marine package. Gusty northwest winds will prevail over the
coastal waters through tomorrow and into thursday morning for the
outer waters. Small craft advisory will be monitored for the
northern San Francisco bay tomorrow afternoon. Surface high
pressure then builds in Thursday evening and will make winds
light and variable through at least the weekend.
