Synopsis A weakening storm system will bring light rainfall to
mainly the northern half of the region through Tuesday morning.

Conditions then dry out late Tuesday into Wednesday before another
weak system brings additional rainfall to much of the region.

With a colder air mass in place, lingering showers are likely on
Friday. A drying trend and cooler temperatures are forecast for
the weekend before a third, potentially stronger system, arrives
late in the weekend.

Discussion As of 9:01 pm pst Monday... Models appear to have a
good handle on the current weather situation this evening. Light
rain has been reported over sonoma and marin for the last few
hours with accumulations anywhere from a hundredth to just under
a tenth of an inch. The approaching system will bring light rain
to the north bay region through late this evening with light
rain spreading south across the greater san francisco bay area
overnight. While the north bay area will see the bulk of the
precip with storm totals around 0.3" to 0.5", models indicate the
trailing end of the frontal boundary will deposit anywhere from
0.1" to 0.2" across the bay area as the front dissipates. The
santa cruz mountain will likely see slightly more due to the
terrain unfortunately little to none is expected from the
monterey bay south.

So far the winds have stayed fairly light with sustained winds
around 5 to 10 mph. Higher elevations in the north and east
bays continue to see elevated gusts to around 20 mph. Breezy
conditions are expected to accompany frontal passage overnight
however widespread gusty winds are not anticipated.

Weak ridging, anticipated for Tuesday and Wednesday, will bring
a return to dry conditions and near normal temperatures as the
region transitions between system.

From previous discussion... Our next system is forecast to arrive
late Wednesday into Thursday and bring additional rainfall to the
region. This system too appears to be generally weak as the bulk
of mid upper level support remains well north of the region.

However, much colder air is forecast to advect southward and
result in lowering snow levels across the state. With a colder air
mass and mid upper level trough aloft, do expect lingering post
frontal showers into Friday. Additional rainfall amounts range
from around 1 4" to 1 2" for most urban areas (greatest in the
north bay and along the coast) with less than 1 4" for our drier
inland valleys. Coastal ranges in the north bay could see upwards
of around 1" with amounts closer to 1 2" for the coastal ranges to
the south.

As conditions dry out late Friday into Saturday, colder overnight
conditions are likely. Look for widespread 30s inland with lower 40s
near the coast Friday night into Saturday morning and again Saturday
night into Sunday morning. Much of this will depend on how much
clearing occurs this weekend so be sure to check back for updated
forecast information.

The forecast models continue to show the potential for a stronger
system to impact the region late in the weekend into early next
week. However, the models and run-to-run solutions do differ on the
details at this time. With that said, do look for widespread
rainfall and slightly stronger winds with this third system. Again,
stay tuned for additional details on potential impacts.

Aviation As of 10:00 pm pst Monday... Little change from the
previous TAF package as light rain is forecast to move across
some of the terminals tonight. Main focus will be north of san
jose. CIGS remain tricky although koak has now dropped down to
MVFR level along with ksts. That should continue into the morning.

Winds generally under 10 kt. Moderate confidence.

Vicinity of ksfo... Latest cig is around 035 which is close to
thinking from the previous package. Would expect it to drop to
around 025 in the next couple of hours. Models continue to show
rain returning around 10z possibly lasting for a few hours.

However, generally returning to dry weather by or even before 14z.

Vfr after 16z. Moderate confidence.

Sfo bridge approach... Rain favored for northern portion of the
approach over the southern portion. Otherwise similar to sfo.

Monterey bay terminals... GenerallyVFR through the period as the
system will be too far to the north. Potential for mvrf at kmry
after 10z. Ksns has already dropped down to ifr and will likely be
there all night.VFR after 16z tomorrow. Moderate to high
confidence.

Marine As of 8:09 pm pst Monday... Southwesterly winds will
continue tonight as a storm system approaches from the west. A
longer period swell will continue to impact the coast through
Tuesday. A larger and more powerful swell will arrive Wednesday
night or Thursday morning.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
