updated aviation section...

Update No significant changes are necessary this morning, as
conditions across the area are coming along well in regards to he
forecast. The exception is fog, which has developed in some of
the valleys of the west side and along the coast. Have updated to
add fog, but have left the remainder of the inherited forecast as
it was. Major forecast efforts today will focus on the upcoming
system for this evening and tonight, and the next system due in
late this weekend. For more information, see the previous
discussion below. -bpn

Aviation 23/12z TAF cycle... Updated 9am pdt...

ifr to MVFR low clouds and patchy ifr to lifr fog has formed since
sunrise across many valley areas this morning. Expect this to
dissipate over the course of the morning leading toVFR as a frontal
system approaches. Southerly winds will increase ahead of the cold
front today, so expect increased turbulence, especially over and
near high terrain and east of the cascades. Winds at the coast will
also become gusty late this afternoon. Ceilings will gradually lower
this evening, from west to east across the forecast area, and expect
mountain obscuration to follow. Btl/sk

Marine Updated 300 am pdt Thursday 23 march 2017... A strong front
offshore will move toward the coastal waters late this morning.

Widespread gales can be expected early this afternoon through this
evening, especially beyond 10 nm from shore, but also closer to
shore near CAPE blanco. A few gusts to storm force are possible.

Seas will become steep to very steep during this time period and
persist through tonight. Winds and seas will decrease Friday into
Saturday... But seas likely remain quite steep. Another strong front
is due to arrive on Sunday. -spilde/sk

Prev discussion /issued 604 am pdt Thu mar 23 2017/
discussion... A frontal boundary will bring gusty winds to our
forecast area this afternoon. Wind advisory continue for the
shasta valley and part of east side of the cascades along with the
warner mountains of modoc county this afternoon through tonight.

Wind forecast at the coast is a little trickier. We generally look
at oth to acv pressure gradient and the character of the low
pressure as well as how the low level winds align against the
coastal range. In this case, while winds at h925 and h850 hpa are
in the 50-60kt range, the gradient is only 6.0 and the low is
farther offshore and not deepening. Also h925 wind direction is
more out of the south and southeast and does not have the sw
direction that forces mass onto the coastal range. I feel that the
coastal headlands and the higher terrain in the coastal range
could see the very strong winds and the high wind watch was
canceled. The coast will still be very windy but the strongest
winds will be mainly at the headlands.

The front is expected to spread precipitation into SW oregon this
afternoon with snow levels around 5000 feet. The front is
expected to move inland tonight and somewhat stalls over the
cascades not exiting until Friday. Crater lake, mt ashland and mt
shasta could see around a foot of new snow by Friday morning.

Precipitation is expected to taper off to light showers by Friday
evening. Scattered showers will continue into Saturday except for
the coast and the umpqua basin where precipitation is expected to
be steadier. Saturday night could be dry but both the GFS and the
ecmwf bring another front inland on Sunday. /fb

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
