What forecasters said that day
The local office's own words before this small craft advisory 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 small craft advisory went out at Aug 13, 11:11 PM PDT, 3 hours 48 minutes earlier.
Area forecast discussion, Aug 13, 11:11 PM PDT, 3 hours 48 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
1111 PM PDT Fri Aug 13 2021
.SYNOPSIS...An interior warming trend is forecast through the
upcoming weekend as high pressure builds westward. Elevated
moisture from remnant tropical moisture will also push inland
through Saturday morning resulting mainly increased high
cloudiness. A region-wide cooling trend is then expected through
early next week.
&&
.DISCUSSION...as of 08:45 PM PDT Friday...Dynamic weather over
the region today featuring a weak 586dm low pressure disturbance
just offshore nestled up on the western periphery of a much
stronger 597dm high pressure monsoonal ridge. Satellite imagery
depicts marine stratus within the first 1500 feet of the coastal
interface, with mid level monsoonal moisture farther east over the
Sierra Nevada, and even higher, the tropical moisture from the
remnants of TS Kevin moving NE. This tropical moisture is riding
up along a warm air mass boundary that is nestled in a corridor
parallel of the coast between the offshore low and monsoonal high
and spreading altocumulus (high cloud) over the area for most,
with some deeper convective cells generating virga or sprinkles
for some in the Bay Area (0.01" was reported at one site on the SF
Peninsula). In addition, there were numerous reports of erratic
gusty winds associated with the arrival of this warm air mass
boundary and these higher based showers, indicative of outflow
boundaries. Interestingly enough, these outflow boundaries were
coinciding with the peak of this evening's seabreeze and in some
locations created a coupling effect with erratic gusty winds in
the tangible 30-45mph range. Between these high clouds covering
most of the region tonight and the encroachment of the marine
stratus near shore, it is unlikely the Perseids will be visible
for most again tonight. Otherwise, mild concentrations of wildfire
smoke will continue permeate the region through the coming days.
For information on the upcoming weekend's forecast and beyond,
please review the previous forecast discussion as there is little
change this evening:
All attention then turns to the high pressure to our east as it
builds westward through the weekended. Forecast ensembles indicate
a 596-598 dm at 500 mb nudging toward the coast resulting in
warming 850 mb temperatures. With values at this level forecast to
reach between 25-28 deg C both Saturday and Sunday, look for a
warming trend across the interior. There remains a great deal of
uncertainty however in exactly how much the persistent marine
influence and even smoke aloft will limit heating in the coastal
valleys. That said, confidence is high with respect to the marine
layer keeping temperatures near the immediate coast in the upper
60s to 70s with better chances for 80s to 90s further inland. With
the warming air mass aloft, looking for temperatures across the
far interior to reach between 100 and 108 deg F both Saturday and
Sunday afternoon. That said, this heat should be limited in
coverage to the region's typical hot spots and thus heat products
have not been issued at this time. It is also worth noting that
locations above the marine inversion will remain mild to very warm
during the overnight hours. Look for 50s to lower 60s in the
lower elevations while the hills, ridges and peaks only cool into
the 70s if not lower 80s through the this weekend. Given this
complex forecast, we will closely monitor the heat potential
through the weekend and make any necessary adjustments along the
way.
Temperatures begin to cool on Monday as a mid/upper level trough
drops southward down the West Coast. Further cooling is likely
through the middle of next week as the trough deepens and promotes
increased onshore flow. With a deepening marine layer also likely
as a result , look for more night/morning low clouds spreading
inland each day along with near to slightly below normal
temperatures.
&&
.AVIATION...as of 11:12 PM PDT Friday...For the 06z TAFs. VFR
across terminals currently, with night satellite revealing coastal
stratus around Monterey Bay. View of any stratus farther north is
obstructed by high clouds. Coastal profilers show marine layer
depth around 1800 ft at Fort Ord, but much more compressed at
Bodega Bay. High confidence in low CIGs filling in around Monterey
Bay terminals overnight, but low confidence in CIGs around SF Bay
as high clouds have slowed marine layer development there.
Scattered echos also showing up on local radar over the coastal
waters, heading towards North Bay. Little, if any impacts expected
at terminals. There also have been hints of patchy light coastal
drizzle developing overnight into Saturday per recent WRF- ARW
model output and to a much lesser extent by the GFS model. Low
clouds clear early to mid-morning leading to VFR conditions
region-wide Saturday.
Vicinity of KSFO...VFR. SCT mid/high clouds from tropical moisture
passing overhead. There may be stratus along the coast, but view
is currently obstructed on satellite. Chance of IFR level CIGs
developing in the early morning hours near the terminal but low
confidence at this point. Light WNW seabreeze easing overnight.
VFR conditions prevail Saturday with continued moderate onshore
winds.
KSFO Bridge Approach...Similar to KSFO.
Monterey Bay...VFR conditions currently at area terminals but
stratus filling in around KMRY, viewed on satellite imagery.
Conditions reduce to IFR/LIFR area-wide overnight with low CIGs
and areas of BR. May see some patchy light drizzle overnight and
Saturday morning, as per some hi-res model members. Not included
in TAFs but will update as necessary. Conditions lifting to MVFR-
VFR by mid to late morning.
&&
.MARINE...as of 8:45 PM PDT Friday...A few showers aloft moving
across the northern coastal waters this evening may produce
locally gusty and erratic outflow winds tonight. Otherwise areas
of gusty northwest winds developing, specifically near where
typical coastal jets set up, through the weekend. Gusty onshore
winds redeveloping Saturday afternoon and evening from the Golden
Gate to the West Delta. The sea state continues to be driven by a
weak southerly and northwesterly swell, as well as northwest wind
waves. Stronger northwest winds persisting into early next week.
