Area Forecast Discussion
National Weather Service San Francisco Bay Area
210 PM PDT Sun May 23 2021
.SYNOPSIS...Building high pressure will result in minor warming
through Monday. Night and morning coastal clouds will become more
common. Slight cool down on Tuesday, then the region warms again.
&&
.DISCUSSION...as of 01:45 PM PDT Sunday...Mostly clear skies this
afternoon for our forecast area. Just some lingering patchy
stratus near Pt Reyes, along the SF Peninsula coast, and over
Monterey Bay. Temperatures this afternoon are currently in the 60s
up to mid 70s and we'll probably see a few more degrees of warming
this afternoon. Expect coastal and valley stratus intrusion again
this evening into tomorrow morning.
High pressure ridge axis is just offshore and will continue to
nudge inland such that the axis should be directly over our CWA
tomorrow. That means we'll have another nice warm-up tomorrow with
daytime highs warmer than today....coastal influenced areas
tomorrow will be in the mid 50s to mid 70s and inland areas will
be mid 70s to mid 80s. Could see a bit of a breezy
afternoon/evening on Monday with some spots having gusts peak in
the 20-25 mph range, while other gusts in our CWA should be
15-20 mph.
On Tuesday, we'll notice a bit of a cooldown as the ridge weakens
and an upper level trough from the Pacific NW swings across
NorCal. This cool down will be brief and generally equate to highs
similar to today (Sunday). Then temperatures rebound on Wednesday
and Thursday with another mild warm up. Overall, this "roller-
coaster" thermometer will be more like a kiddie ride since the
temperature swings won't be that intense this week. Most sites in
our region will remain within 5-6 degrees of normal.
Forecast remains on track with no precipitation expected in the 7
day forecast.

.AVIATION...as of 10:31 AM PDT Sunday...For the 18z TAFs. Stratus
is slowly dissipating around the SF Bay Area while lingering
along the San Mateo Coast and southward. VFR conditions
anticipated over the next couple of hours for all sites through
the late afternoon/early evening. Low clouds look to return this
evening and overnight along the coast and around the Bay Area.
Expect MVFR/IFR cigs to prevail overnight and through mid to late
tomorrow morning. Breezy onshore winds this afternoon around
10-15 kt with locally higher gusts possible.
Vicinity of KSFO...Some low clouds linger around the bay this
morning with MVFR conditions still possible over the next couple
of hours. VFR conditions this afternoon and evening before MVFR
cigs return overnight. W/NW winds this afternoon around 15 kt with
gusts of 20-25 kt possible.
SFO Bridge Approach...Similar to KSFO.
Monterey Bay Terminals...VFR conditions to prevail through the
late afternoon, though satellite currently shows some low clouds
streaming over the Monterey Peninsula. Would not be surprised to
see intermittent MVFR conditions at KMRY today. Stratus returns in
the early evening, confidence low on exact timing. MVFR/IFR
conditions overnight and through mid/late tomorrow morning. W/NW
winds this afternoon 10-15 kt.
&&
.MARINE...as of 01:45 PM PDT Sunday...For today, easing northwest
winds through this morning, then winds strengthen in the afternoon
and evening, particularly along the coast. Then, moderate locally
gusty northwest winds persist on Monday, again especially along
the coast, before strengthening further to locally gale force by
Tuesday. Mixed seas will prevail otherwise with a lighter
northwest swell and a longer period southerly swell.
