747 pm pst Fri feb 23 2018

Synopsis
23 734 pm
temperatures will warm to near normal this weekend then cool again
through the coming week. There is a slight chance of precipitation
Monday and Tuesday and again late in the week but rain or snowfall
amounts would likely be light.

Short term (fri-mon)
23 746 pm

Update...

winds switched from west to east very quickly this evening. This
switch from west to east dropped the wind speeds significantly
and the wind advisories were dropped from all areas. Once again
max temps remained in the 50s for most of the csts and vlys with
just a couple of readings in the lower 60s along the coasts. Dry
north flow will set up aloft along with a slight rise in hgts. The
00z NAM confirms the current forecast for the weekend which looks
pretty good. There will be several degrees of warming each day
and by Sunday MAX temps will be near normal.

The clear skies and cool airmass will combine to bring freezing to
near freezing temps to many vly and inland areas early Saturday
morning and the current suite of frost advisories and freeze
warnings looks on track.

Still low temps will be tricky tonight because the of the offshore
flow. Areas that stay breezy will not see much cooling but in
areas that are wind sheltered (and often times there is not much
distance between a breezy area and a calm one) temps will plummet.

Will update the forecast soon to adjust the winds and remove the
advisory headlines.

***from previous discussion***
trough moved through earlier this morning and now we're firmly in
the north northwest flow behind it. Advisory level winds have been
fairly isolated so far but should see speeds increasing as we
move into the later part of the afternoon so will leave them be
for now. Otherwise we'll transition to a weak offshore flow
pattern over the weekend with warming temps. Still another chilly
night tonight with a series of freeze frost hazards in effect.

Like the highs, overnight lows should warm up a couple degrees
each night through early next week. Offshore gradients peak Sunday
morning, and Sunday should be our warmest day, however without
much in the way of upper support winds should remain below
advisory levels.

Gradients turn onshore Monday ahead of the next trough dropping
south along the west coast. This will cool temps off a few
degrees, especially closer to the coast. That trough, though a
little farther west than the recent troughs, still has a
significant over land component and thus has limited moisture
available to it and really no southerly flow to help it survive
the turn around pt conception. So while chances for rain to the
north are reasonably high, southern areas may get shutout again or
at most get a few hundredths Monday night. And pretty cold air
with it as well so low snow levels again for the mountains and
possibly another inch or two of snow, especially north facing
slopes.

Long term (tue-fri)
23 134 pm
cool and breezy again Tuesday behind the Monday trough but dry
through at least Wednesday and likely Thursday as well. Might have
another round of frost freeze hazards for Tuesday morning in wind
protected areas. The last few model runs of the GFS and now the
latest ECMWF have trended much weaker with the weather system for
the end of next week. Both now push the low east into montana
rather than drop it south off the california coast as they once
did. So while there's still a chance of rain the amounts are a
small fraction of what they were at one time. In fact some of the
ensemble members don't have any rain over the area, though most
support at least some light rain on Friday and a few are still
even holding out for the bigger rain producer that earlier
operational runs supported. Since our Friday pops were already
pretty conservative those have been left alone and we'll see how
this evolves over the next few days. Given the pattern this season
it's hard not to favor the drier scenario now offered by a
majority of the solutions.

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.
