What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS San Francisco Bay Area, CA wrote its last area forecast discussion before this gale warning went out at May 21, 10:44 AM PDT, 3 hours 53 minutes earlier.
Area forecast discussion, May 21, 10:44 AM PDT, 3 hours 53 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
1044 AM PDT Thu May 21 2020
.SYNOPSIS...High pressure will gradually build over the region
through the remainder of the week and more so into the upcoming
holiday weekend. Thus, look for dry conditions and a warming trend
with temperatures trending to above seasonal averages by Saturday.
&&
.DISCUSSION...as of 07:35 AM PDT Thursday... 12Z KOAK sounding
looks warmer in the lower levels this morning as warmer air
advects into the region under increasing pressure aloft. This will
bring a short term warming trend to the region from yesterday
into today, with temperatures roughly 2-6 degrees warmer this
afternoon versus during the day yesterday. Afternoon highs will
peak in the 60s to mid 70s along the coast/shorelines and upper
70s to low 80s inland. By late this evening through tonight, an
upper low presently over the Pacific Northwest will descend
southward and suppress the weak high pressure and result in a very
marginal (1-2 degree) cooling trend from today into Friday. Then,
a high amplitude high pressure ridge will begin to build into the
region later Friday and herald in an extended warming/drying
period that will persist from the Memorial Day weekend through at
least mid week next week. Temperatures reach their peak between
Monday and Wednesday as 850mb temperatures rise up to 23-24C,
potentially bringing the warmest temperatures of the year for most
inland locations, with the most extreme inland locations
potentially reaching for the triple digit mark.
Current forecast package looks on tracking with no changes
planned for this morning. Please see previous discussion for more
details on the current forecast.
.PREVIOUS DISCUSSION...as of 3:44 AM PDT Thursday...No rain in
the forecast the next seven day as high pressure generally prevail
with the first potential heat event of the season.
Overnight satellite imagery shows a shallow marine layer
developing along the immediate coast and moving locally inland.
Much of the cloud cover is confined to the coastal waters south of
the Golden Gate, Monterey Peninsula, near Hollister, and East Bay
Hills. Airport sensors have the clouds deck sitting around 1k
feet. Unlike yesterday, do expect more sunshine along the coast
leading to warmer temperatures. Inland areas will once again see
sunshine with slightly warmer temperatures as well. Highs this
afternoon will max out 60s/70s coast and 70s/80s inland.
A trough sweeping through the PacNW later Thursday night and
Friday will usher in a quick shot of cooler weather and
potentially more night/morning clouds. Temperatures will cool
roughly 1-3 degrees from Thursday to Friday. Regarding clouds,
lowering 500 mb heights and cooler temperatures will help to
develop a shallow marine layer. Counter acting the marine layer
will be weak dry north winds at at 925 mb. Therefore, clouds will
likely be confined along the immediate coast.
No major shift in the forecast for the upcoming holiday weekend
through the middle of next week. The main weather impact for the
Bay Area, and California for that matter, will be the heat. Models
continue to advertise a solid warm up beginning Saturday and
lasting well into next week. The peak of the heat appears to be
next Tuesday and Wednesday with 500 mb heights at almost 590 DAM
with 850 mb temps 22-24C. That would yield a potential for the
first triple digits across the interior. Delving into the ensemble
data reveals some spread, but consensus is on the warmer end of
the envelop. Further analysis of ensemble data compare to
climatology shows more on the extreme end of climo for early next
week. So what does all of this mean? Confidence remains high that
the Bay Area will likely experience the first real heat of the
year with highs in the 90s across the interior, poss 100 far
interior. Farther to the east in the Central Valley highs will
easily surpass 100 degrees. As always with lack of offshore flow
the battle ground will be the Bay Shoreline and coastal areas.
Given the lack of offshore flow and lingering onshore flow
temperatures will be tempered at the coast. However, that does not
mean highs won't be above average, just not really hot. To throw
some more wrinkles in the longer range forecast is a lurking cut
off low off the West Coast next week and above normal sea surface
temperatures. The lurking low remains well offshore through
Wednesday, but may try to usher in some low clouds near the coast.
As for the sea surface temperatures (SST), readings are usually
in the low 50s for this time of year, but recent obs have temps in
the mid-upper 50s. The colder SST and general NW/onshore flow are
some of the drivers of May Gray. So maybe less stratus/May Gray?
The weather may not be as intriguing to some like
hurricanes/tornadoes/thunderstorms, but the nuances of
heat/microclimates make forecasting the weather challenging
nonetheless. Definitely stay tuned to the forecast as details of
the upcoming heat event become more clear.
&&
.AVIATION...as of 10:48 AM PDT Thursday...for 18z TAFs. Drier air
drives mostly clear skies over the Bay Area providing VFR
conditions. The lone exception is the patch of stratus clinging
to the Monterey Peninsula. Winds will remain onshore, but increase
this afternoon, with stronger gusts possible for coastal
terminals. Winds will remain breezy into Thursday night/Friday
morning, as higher clouds build around the region.
Vicinity of KSFO...VFR with onshore winds. Winds are forecast to
increase with gust up to 25 kts after 21Z. Winds will remain
strong through the evening. Cooler temperatures will aide in
developing a shallow marine layer overnight; however, it is
forecast at this time to develop and remain over the coast for low
confidence in providing MVFR conditions Friday morning
SFO Bridge Approach...Similar to KSFO.
Monterey Bay Terminals...A pesky patch of stratus refuses to let
go of the Monterey peninsula keeping KMRY at IFR longer than
anticipated, while the remainder of the area is VFR as forecast.
Winds will remain onshore and increase this afternoon, with an
occasional stronger gusts possible, which will help mix out the
remainder of the stratus. Lower clouds are set to return late
Thursday evening and into Friday morning.
&&
.MARINE...as of 8:34 AM PDT Thursday...As high pressure remains
nearly stationary over the Pacific, moderate-to-strong northwest
winds will be present over the waters through Sunday. Winds will
decrease Sunday and Monday as a ridge builds from the high into
the Pacific Northwest.
