Discussion Yet another system brings snow to the already
healthy snow pack in the higher elevations. Although the 700 mb
winds are slightly more west from the south to southwest direction
normally desired, the gradient briefly peaks around 7 mb from rdd
to mfr and this should bring winds to advisory levels in the
southern shasta valley today, and the winds are already gusting to
near 30 mph at the weed airport at this time. With the gradient at
the coast not tightening as much as we look for and a slightly
offshore component to the winds am not expecting winds to reach
warning levels there. A cold air mass moves in behind the front
this afternoon with 500 mb temperatures moving over the region,
lowering to near -28 c this evening into Monday morning. East of
the cascades the edge of this cold air mass combines with the warm
flow from the south, bringing li's down to near -2 in lake and
klamath counties and possible thunderstorms. The strong lapse
rates keep healthy shower activity with snow levels down to the
cascade passes and over siskiyou summit. With warmer road
temperatures with the higher Sun angles however, snow should melt
quickly and travel impacts should not be long lasting. With the
colder air mass moving in towards Monday morning the impacts may
last a little longer. The cold air mass aloft will shift east
Monday afternoon as an upper level ridge builds into the region.

Tuesday will see a break in the action before the upper ridge
shifts east ahead of the next system that moves in Tuesday night.

The axis of this vigorous jet is well north of the area, but moves
south with the left exit region of the jet over the forecast area
Wednesday evening. Sven

Aviation 26/06z TAF cycle...VFR will continue tonight with
occasional MVFR cigs. Mountains and terrain will be partly obscured.

A cold front will arrive at the coast early this morning and weaken
as it spreads inland through the day. Ahead of this front, a
stronger SW winds aloft could lead to llws at north bend early this
morning, then mid to late morning at roseburg and medford. The front
will also bring increased coverage of MVFR for areas west of the
cascades with local ifr over the coastal range. Snow levels will be
around 5000 to 5500 feet msl. -petrucelli

Marine Updated 230 am pdt Sunday 26 march 2017... South winds are
already increasing and are approaching small craft ahead of the next
front that is still west of the waters. South winds will ramp up
further to gales in the next few hours with gales expected to last
into the afternoon. Steep seas are also expected. The models are in
pretty good agreement pushing the front onshore this evening at
which point winds will decrease and become southwest. However seas
will remain steep through this evening. Seas will decrease tonight
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. Steep seas could
linger through at least Wednesday night. -petrucelli

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.
