Discussion Morning update. It was looking like the back end of
the system was already well onshore earlier this morning, but
latest IR satellite is showing a band of rapidly cooling cloud tops
extending from the mouth of the columbia to the southwest. This
should result in a slowing of the front and another round behind the
the main band moving through the region at this time. Sven

Previous discussion A cold front is approaching the coast this
morning and will bring rain to much of our area, snow to the
mountains, and wind to the coast, shasta valley, and east side
today.

Judging by a wind shift and pressure changes, the front passed
buoy 02 around 1 am local time, which means it is around 250
miles offshore at this hour. The models are all in lock step with
the timing and show it arriving at the coast late this morning
and then marching across the rest of our area through tonight.

The same caveats we've been talking about for the last several
days still apply this morning. That is: winds aloft being westerly
are not as favorable for heavy snow in the shasta area nor strong
winds in the shasta valley as the more common southerly flow would
be. Nevertheless, there will be impacts from snow in the
mountains and wind in the valleys, so the high wind and winter
storm warnings for portions of siskiyou county remain in effect.

The heaviest snow is most likely to impact higher areas such as
the road the mt. Shasta ski area and highway 89 between mt. Shasta
city and mccloud. It is certainly going to snow around mt. Shasta
city, but it wouldn't be surprising to see most of the
accumulations on the trees and grassy areas with roadways just wet
as snow melts. This won't be the case higher up in the siskiyous
and cascades. With snow levels staying at or below 4000 feet
today, we will see all snow over most of the higher passes,
including i-5 at siskiyou summit where up to 4 inches are
possible.

The westerly winds aloft and orientation of the front itself are,
however, favorable for wind impacting more of the coast than
usual. Winds are already gusting to 50 mph at the CAPE blanco, and
with the front still well offshore, this will only increase
through this morning. As the front arrives at the coast late this
morning, winds turn more onshore, and this is when wind impacts
are most likely at the coast. Winds may also impact portions of
the rogue valley. Despite the unfavorable winds aloft, latest mos
guidance does show some wind mixing into the medford area late
this morning and early afternoon.

This front moves off tonight, and much of Monday should be dry.

The next frontal system brings rain back to the coast Tuesday as
its warm front moves across the area. This will be followed by
another strong cold front Tuesday night and Wednesday. This front
has much more southerly flow aloft, and thus impacts from snow and
wind are likely to be more typical. It is also a slow moving
front, and thus precipitation amounts are expected to be much more
significant. The latest forecast has 3-6 inches of rain along the
south coast and into the coastal mountains. This heavy
precipitation is also likely to produce significant snows in the
cascades and siskiyous, possibly including mt. Shasta city again.

We also increased winds in the usual spots for Wednesday. After
that, we settle into a cool, wet period for the rest of the week.

Snow is likely to continue to pile up in the mountains, and this
will eventually include the coastal mountains as snow levels lower
later this week. A lot of changes were made to the forecast
between Tuesday and the end of the week. -wright

Aviation 21 12z TAF cycle...VFR conditions prevail with high
level clouds are streaming over the area ahead of a strong front
that will reach the coast later this morning. Expect CIGS to lower
to MVFR as the front moves inland, possibly lowering to ifr in heavy
rain with frontal passage, especially along the coast.

The main concern with this front will be strong winds aloft leading
to llws for TAF sites along the coast and west of the cascades
through the morning, strong, gusty winds east of the cascades
through this evening, and strong winds over mountain ranges leading
to mountain wave turbulence. Winds will diminish from west to east
beginning later this afternoon. Freezing levels will remain low,
around 3500 feet, so any precipitation east of the cascades will be
snow. Br-y

Marine Updated 815 am pst Sunday 21 jan 2018... A strong front
will move through the waters today. Gales are expected over much of
the waters with storm force winds occurring mainly north of pistol
river and beyond 1 to 2 nm from shore, except near shore within the
vicinity of CAPE blanco. Very steep and hazardous wind driven seas
will peak early this afternoon at around 23 feet. Winds will
diminish this afternoon and seas will gradually diminish this
evening, but will remain very steep and hazardous at 15 to 18 feet
through Monday morning. Seas will remain elevated through at least
Monday night.

Active weather will continue through the week. The next system is
expected Tuesday morning and another round of gales will be possible
ahead of this system. Fb

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.
