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 Apr 30, 5:01 PM PDT, 3 hours 56 minutes earlier.
Area forecast discussion, Apr 30, 5:01 PM PDT, 3 hours 56 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
501 PM PDT Mon Apr 30 2018
.SYNOPSIS...An upper level trough and weak weather disturbances
will impact the region through Tuesday resulting in a slight
chance of showers in the hills/mountains. High pressure will then
build over the region late in the week to produce a warming and
drying trend into the upcoming weekend.
&&
.DISCUSSION...as of 01:43 PM PDT Monday...As the HRRR and local
WRF suggested, showers have developed over portions of Napa County
this afternoon with a decent amount of cumulus clouds. This is
all in response to a colder air mass aloft and a weak short-wave
disturbance approaching from the northwest. Elsewhere, a mix of
sun and clouds persist with temperatures ranging from the upper
50s to middle 60s. Look for showers to diminish this evening by
around sunset with overnight temperatures likely to fall into the
40s for most urban locations.
Cannot rule out sprinkles or light rain showers over the northwest
facing slopes across the Central Coast (similar to this morning)
late tonight into early Tuesday morning as the broad mid/upper level
trough drops southward across the region. In addition, another short-
wave trough/vort max will pass over the region Tuesday afternoon and
evening to provide another chance of rain showers, mainly over the
hills/mountains of Monterey and San Benito Counties.
High pressure is then forecast to build out over the eastern Pacific
in wake of the passing mid/upper level trough. By late week, the
ridge of high pressure will shift toward the coast and will allow
for a warming and drying trend heading into the upcoming weekend. By
Thursday, 70s will be more common inland for afternoon temperatures
with lower/middle 60s at the coast. Temperatures are then likely to
warm into the lower 80s on Friday across the warmer inland locations
with upper 60s to lower 70s at the coast. Mild and dry weather
appears to persist heading into next week as well with the region
dominated by the ridge of high pressure.
&&
.AVIATION...As of 4:40 PM PDT Monday...For 00z Tafs. Despite the
lack of a marine layer patchy clouds persist across the region.
The only terminals currently being impacted are in the Monterey
Bay vicinity. VFR conditions expected across the area tonight with
MVFR cigs expected to only scatter out temporarily this evening
over Monterey Bay area terminals before returning once again
tonight.
Moderate confidence overall given the multiple cloud layers.
Vicinity of KSFO...VFR conditions will prevail through the
forecast period with few to sct clouds decks possible overnight.
Gusty westerly winds this afternoon of 15 to 25 kt will ease late
tonight into Tuesday morning. Moderate winds expected to ramp up
once again Tuesday afternoon.
SFO Bridge Approach...Similar to KSFO with possible cigs expected
late tonight into Tuesday morning near the San Mateo bridge
affecting the approach. Clearing anticipated Tuesday afternoon.
Monterey Bay Terminals...Borderline MVFR/VFR cigs persist over
area terminals and surrounding areas. Cigs anticipated to scatter
out temporarily before returning this evening. MVFR cigs expected
overnight. Cigs will scatter out around 18z Tuesday over KSNS
while KMRY will once again likely only see partial clearing if at
all. Moderate and gusty winds of 15 to 25 kt will gradually ease
late tonight to around 10 kt.
&&
.MARINE...as of 04:39 PM PDT Monday...A strong pressure gradient
over the waters will continue to produce gale force winds,
especially over the northern outer waters overnight into Tuesday
along with gusty winds along the Big Sur coast. The strong winds
will produce fresh and choppy seas with short periods. Winds will
gradually ease later Tuesday into Wednesday. Lighter wind and
seas are forecast Thursday and Friday as high pressure returns
and surface gradients relax.
