Synopsis High pressure aloft will shift east of the region
later today as a front approaches the area. The front will spread
rain across western washington on Wednesday. Weak high pressure
will build back into the area on Thursday. A series of weather
systems will pass mainly to our north Friday into the weekend
keeping temperatures near normal and bringing a chance of showers
to mainly the coast and north interior.

Short term today through Thursday Mostly clear skies prevail
across western washington early this morning with temperatures
most areas falling into the 50s as of 2 am pdt. A few spots in the
southwest interior may dip into the upper 40s before sunrise... A
sign of the longer nights ahead. High pressure aloft will weaken
and shift east of the region today as a fairly potent system
offshore sends a front our direction. The front will weaken as the
parent surface low shifts into the central b.C. Coast tonight, but
it will hold together well enough to bring a soaking rain to
coastal areas by daybreak Wednesday.

That rain will spread into the puget sound area by mid morning
Wednesday. Models have bounced around a bit with regards to qpf,
but seem to be settling on an inch or more for much of the coast
and possibly a quarter to half inch or so for the puget sound
area. Along with all the clouds will come cooler temperatures with
highs mostly in the 60s across the area. The front will quickly
shift east of the cascades Wednesday evening. Mesoscale models
shows a fairly well defined convergence zone developing near the
king snohomish county line Wednesday night before dissipating it
by daybreak Thursday. Weak high pressure aloft will build into the
region on Thursday with some Sun breaking out by mid or late
afternoon and high temperatures returning to something that
resembles normal.

Long term Friday through Monday Upper ridging gets flattened
fairly quickly by later Friday as the first of series of weather
systems move into british columbia. For the most part, the weekend
looks dry with exception of a few showers possible near the coast
and across the north interior. Persistent onshore flow will keep
temperatures near normal. Both the GFS and euro are hinting at the
return of high pressure aloft by Monday. If the models maintain
their current trends, we could be in for a bit of a pattern change
to close out august with higher amplitude ridging and much warmer
temperatures. 27

Aviation An upper ridge over the area will shift inland today
and tonight as a frontal system approaches from the west with
increasing southwest flow aloft. The aforementioned front will
reach the coast later tonight. The air mass is dry and stable.

Low clouds will be patchy at best this morning with weak onshore
flow. There could also be a few patches of fog in the usual valley
locations this morning. Moisture will increase from the west
tonight as a front moves into the area. Low clouds should develop
at the coast tonight and then spread into the interior on
Wednesday.

Ksea... High clouds at times today. Mid clouds should arrive
Wednesday morning with ceilings lowering further by late morning
as a front arrives. Light northerly wind early this morning will
turn southerly today. Schneider

Marine Weak onshore flow will continue today with a ridge along
the coast and lower pressure east of the cascades.

A fairly vigorous frontal system - at least for august - will
move through the area tonight and Wednesday. Small craft advisory
strength southerly winds will develop most areas as the front
moves into the area tonight and Wednesday morning with westerly
winds behind the front later Wednesday and Wednesday night.

Onshore flow will resume on Thursday and continue through the end
of the week. A weak front will brush the area later Friday and
Saturday with minimal affect on the winds. Schneider

Hydrology The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.

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.
