Synopsis
A cold front pushing through the area from the west this evening
will conitnue to bring clouds and showers to the region. An upper
low will slowly move east across southwest bc through the rest of
this week, allowing for scattered showers to linger Thursday and
Friday but decrease each day. A ridge of high pressure will build
in over the pacific NW by this weekend and produce a significant
drying and warming trend with temperatures reaching above normal
for several days this weekend and into next week.

Short term tonight through Saturday
As of 0300z or 800 pm pdt this evening, radar shows showers
continuing across the area. Surface observations depict a
continued southerly flow over puget sound with dew points
remaining from the upper 50s to mid 60s and temperatures generally
in the low to mid 60s. It has been a cloudy and wet july day, and
rainfall amounts were enough to break daily records at the
airports in bellingham and at quillayute. Rainfall totals depict
that a few spots exceeded an inch of rain today, especially in the
southwest facing slopes of the olympics and some spots in the
north cascades. Generally, however, rainfall totals were less than
a quarter of an inch in the lowlands. Showers will continue but
slowly diminish in coverage overnight from west to east. Thursday
will feature little change in the mid level features over the area
but a low will drift slowly east across southwest bc. This will
provide a few showers Thursday. While the bulk of these will be
confined to more northern and mountain areas, there should be a
chance of showers for most all areas Thursday afternoon except for
far southwest portions of our region. Temperatures will rebound
slightly tomorrow but remain in the upper 60s to low 70s. By
Friday this low over southwest bc will exit east and 500 mb
heights are expected to rise slightly throughout the day. This
will set the stage for a warming trend Friday by several degrees,
to push highs above normal. Showers will diminsh to the point
where only high terrain in the olympics and north cascades might
see a few. Otherwise it looks to be dry with less cloudiness. More
substantial increases in 500mb heights are set to take place
Saturday and so the surface temperatures should see a strong
rebound from the cool weather of today. With skies becoming
sunny, temps will reach into the low 80s in many areas by
Saturday. Johnson

Long term Sunday through Wednesday
Regionally, a four corners high builds strongly Sunday and early
next week, affecting heights over the pacific northwest as well.

Heights will be in the 580s through Wednesday at least.

Southwesterly flow aloft should give sunny skies and highs in the
80s. Varying degrees of low level onshore flow will keep
temperatures from getting much warmer than that. The GFS brings an
upper trough close to the coast by Wednesday and the euro brings
it close about a day sooner. Upper flow turns more southerly by
Wednesday, perhaps bringing a chance of showers to the mountains,
but for now have kept the forecast dry. Burke

Aviation
A cold front pushing across the olympic peninsula will bring a
continued chance of showers and breezy winds from the sw
overnight. Winds should diminish to around 10 knots or less after
10-12z. Showers will diminish as well. Through that time however,
skies will remain variable and bouncing fromVFR to occasional ifr
if any showers move overhead. The general trend will be for
conditions to slowly improve to the MVFR-vfr range for ceilings
during the 15-18z thu. Time frame. Winds will slowly shift more
westerly during this time period but remain around 10 knots.

Ksea...

southwest winds around 10-12 knots will persist through the
period, except they will shift more westerly after about 17z
Thursday. Showers will coninue this evening with reduction of
visby CIGS into the MVFR category. Showers will diminish by 12z
Thursday. However, MVFR conditions will persist with slow
improvement toVFR Thursday afternoon.

Marine Westerly gales are expected as the surface cold front
slowly passes through the central and eastern strait of juan de
fuca. Westerly gales also possible Thursday night in the central
and eastern strait of juan de fuca. Onshore flow Thursday will
ease Friday and then the winds over the weekend should more
typical summertime diurnal sea- breezes with advisory level
westerlies likely in the central and eastern strait of juan de
fuca for the late afternoon and evening hours.

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.
