Discussion 28/12z NAM in.

The northern hemispheric projection continues to show a wave
number of four around the globe and occasionally hints at a five
over the next several days. This argues for a moderately
progressive pattern. That is what we will get over the next few
days... But it will slow down towards the end of the week. Overall
the pattern looks quite spring like... With weaker storms driven by
low amplitude upper level troughs. The primary storm track will
remain to the north of the area... But there will be some action
down here.

A long wave ridge continues to build into the west coast this
morning. There was some light shower activity over the
umpqua... Western siskiyou county... And the coast earlier this
morning but all appears quiet now.

The ridge will bring dry and warmer weather to the area today.

The ridge axis will flatten and break to the east of the area late
tonight into early Wednesday. A short wave riding up the back
side of the ridge will move onshore to the north of the area
Wednesday morning. A warm front will move onshore Tuesday
night... Followed by a trailing cold front Wednesday afternoon.

With most of the upper level support remaining to the north... Both
fronts will be relatively weak this far south. Even so... Most if
not all of the medford CWA will get some light precipitation
Tuesday night into Wednesday night. Snow levels will be way up
there... Around 8000 feet. A stronger short wave with a more
southerly trajectory will move onshore late Wednesday night or
early Thursday morning with the long wave trough. This along with
short waves diving down the back side of the trough will support
post-frontal showers lasting into Thursday evening... But shower
intensity and coverage will diminish through the day Thursday.

Snow levels will drop to 3000-4000 feet with the trough... But the
heaviest precipitation will have already fallen by that time.

Cold air will pour into the region behind the system, and this
transition will result in gusty northwest winds across the east
side Thursday afternoon and evening. Temperatures will then be
much colder over the entire region, although not much below
normal for this time of year. Areas of frost are possible in the
west side valleys Friday morning, where some sensitive vegetation
may have started spring growth.

After that... Another long wave ridge will build into the west
coast and this will bring another round of dry and warmer weather
beginning Friday and continuing into Saturday.

Aviation 28/12z TAF cycle...VFR conditions are expected across
the area today with partial mountain obscurations. Rain and mid
level clouds will increase tonight as a front approaches the area.

Ceilings will lower at the coast and approach MVFR around 06z.

Inland expectVFR to continue tonight but mountain obscurations will
increase from the cascades west. /cc

Marine Updated 300 am pdt Tuesday 28 march 2017... High pressure
will remain over the waters today and seas will be dominated by a
west swell at 12 seconds and another west swell at 18 seconds. Seas
will remain high and steep through Wednesday night... Largely due to
a front which will bring increasing southerly winds and steep seas
Tuesday night into Wednesday morning. Wind speeds are expected to
reach advisory strength for areas north of gold beach. Winds will
decrease Wednesday evening and then veer to the north Wednesday
night into Thursday. Winds may reach advisory strength in the outer
waters south of gold beach late Thursday afternoon into Saturday.

Confidence is low in the forecast beginning Saturday and into early
next week with additional storms possible. /cc

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.
