429 pm pst Mon jan 22 2018

Synopsis Central coast lingering showers will quickly end this
evening. Otherwise look for partly cloudy skies tonight with
patchy fog developing in the valleys. Dry and seasonably cool
weather forecast Tuesday. Next front arrives weds morning or
midday in the north bay and then spreads rain southward later weds
afternoon into weds night for the bay area into the central
coast. Steady rain quickly turns to showers before sunrise
Thursday. A round of more organized showers is possible Thursday
afternoon as the upper low moves inland. Dry weather forecast
Friday through the weekend and into early next week.

Discussion As of 2:05 pm pst Monday... Kmux radar picking up
the last few showers across the central coast as the frontal band
that passed through the area last night and this morning
dissipates. Short term concern for tonight will be some fog
development with moist boundary layer and high pressure building
in which should strengthen valley inversions.

Outside of morning fog no real weather concerns for Tuesday with
dry and seasonably cool weather forecast as high pressure briefly
builds.

Run of the mill pacific frontal passage on tap for weds. As has
been the trend of late, the models seem to be showing a less
robust frontal passage. Latest timing would bring steady frontal
rains into the north bay later weds morning or around midday.

Front will then slide southward through the bay area weds
afternoon and evening. Similar to todays front, the rain will
weaken and become more disorganized by the time it reaches the
central coast. The north bay coastal hills will be the winners
once again with 1-2 inches of rain possible while amounts will
drop off sharply over the bay area and central coast. Winds
associated with the front will be fairly light too, some gusts in
the 25-35 mph range as the front passes through.

Any steady rain will quickly turn to showers before sunrise
Thursday. Cold air aloft and an associated shortwave are forecast
to pass through on Thursday afternoon. This should produce an
organized area of rain and isolated thunderstorms, especially
focused from about the santa cruz mtns northward. Some brief heavy
rain and small hail will be possible as this feature passes
through.

Dry weather returns Thursday night into Friday. Latest model
trends show above average confidence for dry conditions Friday
through the weekend and into early next week. Some of the gfs
solutions keep the storm track just to our north but ensembles
suggest another west coast ridge could become entrenched so the
wed-thu rain may be the last significant rainfall for awhile.

Aviation As of 4:30 pm pst Monday... A weak front is now south
of the mry bay area. CIGS have started to break out except in the
mry bay area but abundant moisture remains over the area behind
the front. Therefore expect MVFR CIGS to redevelop in the sfo bay
area by around midnight. With light northeast flow expected later
tonight this could bring some fog from the inland valley into sfo
oak and the approach. Areas of dense fog is expected in the north
bay valleys while vsbys could drop as low as 1-3 miles in the sfo
bay area between 12z and 17z.

Vicinity of ksfo... MVFR CIGS expected to redevelop after 08z.

Vsbys may drop down to 1-3 miles between 12z and 17z. West winds
to 10 kts becoming light northeast after 08z.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... MVFR CIGS will be breaking up in the next
hour and there will be a brief period ofVFR. However MVFR cigs
are expected to return after 05-06z due to abundant low-level
moisture.

Marine As of 4:30 pm pst Monday... Switch to northwesterly
winds is progressing down the coast behind the dissipating cold
front, now located along the northern big sur coast. Small craft
advisories remain in place due to hazardous sea conditions caused
by large swells. These swells will continue to gradually decrease
through Tuesday. However, the next frontal system is set to arrive
mid-week bringing back strengthening southerly winds and
increasing northwest swell.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
