Updated marine and aviation discussion
Discussion As we head farther and farther into spring, nature
finally realizes that maybe it has overreacted in its
overcompensation for the several past years of drought and is
allowing longer periods of relief between the periods of hosing.

Generally light showers will continue to taper off through the
day. A weak upper level ridge will build over the region, dropping
off the showers, but onshore flow will continue to bring in
clouds and keep the area cool. However, at least it won't be
pouring rain through the weekend, at least until the next system
comes in Sunday and that's something nice isn't it? If you like to
be wet then happiness arrives again Sunday with yet another
system moving in on the left exit region of a 120 kt jet. This
will bring increased winds ahead of the front in the shasta and
illinois valleys, but they should stay below advisory strength
withonly weak to moderate gradients. 700 mb winds become more
westerly as the bulk of the moisture moves in, and this flow
pattern will still bring increased precipitation to the mt shasta
area, but not as much as if the flow was more and stronger
southerly. A cold air mass moves in behind the front Sunday
afternoon with 500 mb temps of around -27c moving in Sunday
afternoon into the evening. With a high of 54 this means that
there should be enough instability to bring a slight chance of
showers as several strong vort axises move through and the GFS is
showing li's of below -1 over portions of the east side Sunday
afternoon. Showers continue through Monday morning as a deep
upper level trough moves through before tapering off Monday
afternoon as an upper level right once again builds over the
area. This will bring a break in the action Tuesday before the
next hosing arrives Wednesday. Sven

Aviation 25/12z TAF cycle...VFR CIGS are expected to be the
predominate condition for the next 24 hours. The exception will be
in the mount shasta area where ifr CIGS will linger for most of the
morning before improving. Also MVFR CIGS near lakeview are expected
until at least 18z. Still could not rule out brief ifr CIGS in
klamath falls around daybreak, but confidence is not high enough to
include it in the taf. This will need to be watched closely, so
watch for updates on this. -petrucelli

Marine Updated 456 am pdt Saturday 25 march 2017... Seas have
diminished some this morning and should remain below 10 feet for
most of the morning. Buoy 46002 last reported seas just over 11
feet, but several other ones are less than 10 feet. Despite this,
we'll keep the small craft headline out with seas expected to
increase above 10 feet later this morning due to an increasing west
swell. Winds for the most part are not expected to be a concern
through this evening. A front will move towards the waters later
tonight with increasing south winds. Right now they should remain
below small craft until later tonight, then will ramp up fairly
quickly to gales by Sunday morning as the front reaches the outer
waters. Steep seas are also expected. Kept the gale watch out, but
suspect this will be upgraded to a warning later today. The models
are in pretty good agreement pushing the front onshore Sunday
evening at which point winds will decrease and become southwest.

However seas will remain steep through Sunday evening. Seas will
decrease Sunday night into early Monday morning, then a combination
of a longer period and shorter period west swell is due to move in
Monday afternoon resulting in combined seas between 10-13 feet.

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.
