Synopsis Typical march pattern, as will maintain cool temperatures
and plenty of clouds, along with occasional showers. May see a brief
break in the weather Monday into tue, but then will see return of
clouds and occasional precipitation. Though snow will fall in the
cascades, precipitation not all that heavy so snow accumulations
generally in the few inches per day range.

Short term Today through Monday... Generally, not a lot of change
in the overall weather pattern. Cool upper low pres will sit over the
pac NW this weekend. With the main upper low centered over the great
basin, will continue to see counter-clockwise circulation which will
keep some instability over the cascades, and to some degree a bit
farther to the west. But, overall flow aloft will trend back to the
north or northwesterly later in the day, with will push the best
chance of showers back to over cascades and eastward. Will keep a mix
of mostly clouds and some sunny breaks for areas to west of the
cascades, but will also keep a minor chance of showers.

Next disturbance will drop southward from british columbia today and
tonight. But, appears the it will track offshore along the coast as
it drops southward. This will keep highest chance of showers along
the coast coast mtns and westward later tonight into early sun
morning. But as the day progresses, showers will spread farther
inland. This low will sit off the oregon coast Sun night into mon,
though it will be weakening and ever so slowly drifting west a tad
more. This will allow for much less chance of showers on mon, so will
trend forecasts in that direction.

Snow levels will continue to hover 2000 to 3000 feet. But, rainfall
amounts will not be all that much. Would only expect a few inches at
worst today, then again on Sun for the cascades. dean

Long term Monday night through Friday... Not much change to the
long term forecast today. Weak shortwave ridging will persist Monday
night and into Tuesday as a large low remains in place over the
pacific ocean off the coast of california. This will bring another
dry day Tuesday for most locations with valley temperatures warming
to near or slightly above seasonal norms. However, the pattern will
shift later Tuesday as the california low interactions with a
shortwave trough to provide for the low to open into a trough and
advance eastward into the western u.S., bringing a return of rain to
the region by Tuesday night. This opens the door for another cold air
mass to move into the pacific NW during the middle to late stages of
next week, bringing cooler temperatures and a return to widespread
precipitation. Snow levels rise to around 5000 feet in the warm
sector late Tuesday through Wednesday evening, but will again lower
well below the cascade passes by late next week. Cullen

Aviation Light winds and plenty of low level moisture should
lead to MVFR thresholds developing for several hours this
morning at many TAF sites. Daytime heating should then result in
predominantlyVFR conditions areawide this afternoon. Additional
flight restrictions may develop after 09z Sunday, but confidence
is low in whether or not it will end up being MVFR stratus or
lifr fog at this point.

Kpdx and approaches... Light winds and plenty of low level moisture
should lead to a mix of MVFR andVFR conditions this morning.

Expect conditions to improve to predominantlyVFR this afternoon.

Flight restrictions may return after 09z Sunday, but confidence
is low. neuman

Marine High pressure will slowly build across the waters through
early next week. A series of weak fronts will likely bring higher
(above 10 ft) seas and periods of small craft advisory level
wind gusts of 25 kt to the waters during the latter half of next
week. neuman

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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 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.
