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 systems
will pass generally to our north Friday into the weekend keeping
temperatures near normal and bringing a chance of showers mainly
to the coast and northern areas.

Short term today through Thursday Mostly sunny skies this
morning with generally light surface flow. Dry weather through
today as an upper level ridge slides east of the area this
afternoon. High temperatures will be in the 70s to low 80s. High
clouds will increase through the afternoon ahead of the next
fairly potent frontal system near 45n 135w. The surface low will
shift into central b.C. Coast tonight as the front holds together
to bring a soaking rain to coastal areas by later tonight.

The rain will spread into the puget sound area by mid morning on
Wednesday. Models have fluctuated a bit on QPF amounts but seem to
be settling around an inch for the coast with possibly a quarter
of an inch to a half an inch or so in spots for the puget sound
area. The front will quickly slide through the area Wednesday and
be east of the cascades by the evening. Mesoscale models do
suggest convergence zone formation Wednesday night over snohomish
county and drifting south into king county before dissipating by
daybreak on Thursday. Cloudy skies with cooler temperatures on
Wednesday with highs in the 60s.

A few lingering showers possible Thursday morning, especially in
the cascades, otherwise dry weather expected with weak high
pressure aloft. Some Sun during the hours of Thursday afternoon
with highs in the mid 60s to mid 70s across the area. Jd

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 approaching frontal system will bring increasing mid
and high level clouds and strengthening southwest flow aloft. The
front is expected to reach the coast this evening will reach the
coast after midnight with low clouds and rain spreading inland
through the morning. Conditions will remainVFR across the area
through much of the avignon with ceilings lowering to MVFR levels
along the coast after 06z and then through the interior 12-15z. Ifr
conditions are possible Wednesday morning at some locations as rain
moves onshore and inland.

Ksea... Increasing mid and high level clouds today.VFR conditions
will persist through this evening with ceilings lowering around
daybreak to MVFR levels and as rain moves through the metro area
through the morning. Light northerly winds will become southerly 6
to 8 kt around 18z.

Marine Weak onshore flow today ahead of a fairly vigorous
frontal system approaching the coastal waters. Increasing
southerlies ahead of the front will result in small craft advisory
conditions most waters as the front moves into the area tonight and
Wednesday morning. Onshore flow and westerlies will follow behind
the front later Wednesday and Wednesday night.

Onshore flow will linger continue through the end of the week with
periods of small craft conditions possible in the central and
eastern strait. A weak front will brush the area later Friday and
Saturday with minimal affect on the winds.

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

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.
