Area Forecast Discussion
National Weather Service San Francisco CA
254 AM PST Sun Dec 1 2024

...New SYNOPSIS, SHORT TERM, LONG TERM...

.SYNOPSIS...
Issued at 241 AM PST Sun Dec 1 2024

Warm and dry conditions persist through at least the first week of
December.

&&

.SHORT TERM...
(Today and tonight)
Issued at 241 AM PST Sun Dec 1 2024

Building high pressure across the West Coast and an upper-level low
off the California Coast remains the name of the game. The upper-
level low is responsible for the returns visible on KMUX trekking
northwards out of San Luis Obispo County. At first glance the
radar may look impressive, but surface dew point depressions
quickly negate that. For what it`s worth, locations to the south
have not even recorded any measurable rainfall. If anything,
expect virga and a colorful sunrise. Aside from that, the first
day of December and meteorological winter will feel anything but
with temperatures up to 15 degrees above average as high pressure
continues to build into place. For you climate buffs, while
Monterey Airport is not yet a climate site due to it being too
young (less than 30 years old), it did break a record for daily
maximum temperature on November 30th by reaching 70 degrees,
breaking the previous record of 69 degrees set in 2008 and again
in 2021.

&&

.LONG TERM...
(Monday through Saturday)
Issued at 241 AM PST Sun Dec 1 2024

High confidence in ridging dominating the pattern at least through
the first week of December. As a result, above average temperatures
and dry conditions are expected.

&&

.AVIATION...
(06Z TAFS)
Issued at 926 PM PST Sat Nov 30 2024

No major changes to the forecast as VFR conditions prevail. Some
hi-res guidance has KSTS shows going down to IFR or LIFR status
for a few hours overnight, and given the previous trends, opted to
keep that in their forecast. Not sure if that will pan out given
the high clouds that have moved in, thus confidence is medium to
low for IFR/LIFR conditions.

Vicinity of SFO... VFR conditions will prevail with light east to
southeast winds of less than 10kt forecast. Winds could be variable
at times

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR conditions will prevail with high
clouds filtering into the region. Winds should generally be light
and offshore for the period, but may be variable at times.

&&

.MARINE...
Issued at 926 PM PST Sat Nov 30 2024

Weak to moderate northerly winds continue over the waters with
light seas through the forecast period. Longer period swells
arrive early in the work week.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
