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 Jun 30, 11:43 PM PDT, 3 hours 16 minutes earlier.
Area forecast discussion, Jun 30, 11:43 PM PDT, 3 hours 16 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
1143 PM PDT Wed Jun 30 2021
.SYNOPSIS...A prevailing, seasonable weather pattern will lead into
the Fourth of July holiday weekend. Temperatures will remain near
seasonal normals with a well established marine layer resulting in
low clouds, fog and possibly patchy light drizzle spreading inland
during the night and morning hours.
&&
.DISCUSSION...as of 09:01 PM PDT Wednesday...Models remain
consistent when looking at broader weather pattern heading into
the holiday weekend. The upper level trough west of Seattle will
continue to track northward into British Columbia. Meanwhile, the
high pressure will slowly build over eastern California and
gradually migrate and take up residence over the Four Corners of
the desert southwest. Temperatures at 850 mb will likely stay
between 22 and 24 degrees Celsius through the weekend. This will
keep temperatures approximately normal at surface in the 80s and
low 90s for inland areas and higher elevations. Coastal regions
will continually see cooler afternoon temperatures in the 60s and
low 70s due to the well defined marine layer and persistent
onshore flow. With such a persistent pattern, patchy coastal
drizzle was left in the forecast, as some low clouds map cause a
bucket tip or two Thursday morning. The next chance for a stronger
trough over the Pacific approaching the California coast look to
be next week. But ensembles are keeping it closer to the
California/Oregon border, with no significant moisture plume.
West/northwest winds over the ocean will likely increase, but stay
confined to the coast. Tomorrow starts "No Sky July" for the Bay
Area, and it does not appear that will be losing the marine layer
anytime soon.
&&
.PREV DISCUSSION...as of 01:50 PM PDT Wednesday...Very little day-to-
day change anticipated across the region through the upcoming
holiday weekend. This is as high pressure aloft builds over the
Desert Southwest while weak low pressure develops well off of the
California Coast. Look for this pattern to support a continued
well defined marine layer with the typical ebb and flow of marine
stratus and potentially patchy coastal drizzle through the
remainder of the week. As clouds retreat back to the coast each
afternoon, mostly sunny conditions inland will give way to
widespread 80s to 90s while coastal areas hold in the 60s to lower
70s.
Ensemble members are showing little change in the broader pattern
aloft with high pressure to our east and troughing to the north
heading into next week. Thus, a rather quiet weather pattern with
minor day-to-day changes look to continue through much of next week
as well.
