Synopsis An upper trough will bring clouds and a few showers
Tuesday and Tuesday night. Weak high pressure aloft will bring dry
and warmer weather Wednesday and Thursday. A weak frontal system
will bring another chance of showers later Friday. Dry onshore flow
will prevail next weekend.

Short term today through Thursday An upper trough is
approaching the region today and will move through the area tonight.

Onshore flow continues to push stratus inland from the coast this
morning. Most of the lowlands with the exception of parts of the
north interior should be covered by later this morning then low
clouds will lift and burn off. The clouds and stronger onshore flow
will cool highs to near or slightly below normal. Southerly flow
aloft and some instability over the cascades will produce a slight
chance of thunderstorms this afternoon and evening. As the upper
trough moves through the region, there's a chance of a few showers
over the lowlands from about seattle northward late this afternoon
through early Wednesday morning. A few showers will probably linger
over the cascades on Wednesday. Otherwise, it looks mainly dry as
weak high pressure aloft moves over the area. Morning clouds should
burn off for a partly to mostly sunny afternoon. Highs will warm a
few degrees. The drying and modest warming trend should continue
into Thursday with a flat upper ridge over the area and high
temperatures a few degrees above normal.

Long term Friday through Monday Upper ridging weakens
on Friday with another trough clipping the area Friday night. It
might be strong enough to produce a few showers over the northern
half of the forecast area. Clouds and a few showers could linger
into the first part of Saturday then upper ridging rebuilds for the
second half of the weekend with dry and warmer conditions. Much like
the pattern of the past week or two, models flatten the ridge again
early next week for increasing onshore flow and cooler temperatures
but generally dry conditions.

Aviation Upper level trough moving through the area late today.

Southwesterly flow aloft becoming northwesterly Wednesday morning.

Low level onshore flow today increasing tonight behind the trough.

Stratus with ceilings below 1000 feet along the coast, moving down
the strait of juan de fuca into whidbey island and through the
lower chehalis valley into the southern portion of the hood canal
at 3 am 10z. Mid level clouds over the eastern portion of the
area. Stratus will continue to slowly move inland reaching the
puget sound area 12z-14z. The layer over the puget sound will be
shallow and retreat west of the puget sound by late morning.

Stratus will continue to retreat back to the coast by early
afternoon with mid level clouds over the area. Increasing onshore
flow tonight behind the trough will bring stratus back into the
interior 06z-09z with ceilings in the 1000-2000 foot range.

Ksea... Stratus reaching the terminal about 14z with ceilings
around 1000 feet lasting until around 18z. Mid level clouds this
afternoon. Stratus returning to the terminal around 08z tonight
with ceilings 1000-2000 feet. Light and variable winds becoming
west southwesterly 4 to 8 knots this afternoon. Felton

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.
