Synopsis
Northeast winds will continue to gradually push smoke out of the
idaho panhandle and eastern washington today, while smoke
from fires to the north and east replace it to some degree.

Lighter winds in north central washington may do little to improve
the east slopes of the cascades. Wednesday will feature warm
temperatures and light winds. The arrival of a vigorous cold front
on Thursday will produce breezy west winds. Much cooler and
cleaner air is expected by Friday into the weekend. There may even
be a decent chance for showers Sunday and Monday.

Discussion
Tonight through Thursday night: well now that the upper level low
that was earlier advertised to retrogress back off the coast and
eject as an open wave on Wednesday is instead going to drift away
via a different route through oregon and southern idaho then up into
montana by Wednesday. This different route leaves the positively
tilted ridge of high pressure lingering and slowly sagging overhead
of eastern washington and north idaho through Wednesday. Subtle
changes to note with this occurrence is a surge of marine moisture
into western washington Wednesday and some minor disturbances riding
along Wednesday afternoon and evening with the proper timing to get
the winds somewhat gusty and downvalley late Wednesday
afternoon early evening. This is all followed by a more proper and
vigorous cold front passage Thursday bringing more widespread gusty
wind. Perhaps some minor pops for sparse and spotty post frontal
convection may be introduced for Thursday night but the cooling of
the front will definitely be noticeable by viewing the cooler
forecast high temperatures for Friday. Guidance best handling the
temperatures, as far as not overforecast the highs too substantially
given the smoke nuisance complicating the radiational heating during
the day, has been the consraw so have been utilizing it for max
temps thru Thursday and as such have been cutting back slightly on
what the bccconall and bccconraw suggests for overnight lows based
on somewhat similar smoke issue (efficient radiational cooling at
night). Pelatti

Aviation
18z tafs: positively tilted flop-over ridge to keep a dry and
smokey northeast flow over the aviation area. Minor improvements
in visibility will happen from time to time with the best
improvement expected with Thursday's cold front passage,
otherwise MVFR visibilities due to smoke to prevail. Pelatti

Fire weather The flop over ridge keeps widespread fair to poor
overnight relative humidity recoveries in place for the next two
nights (tonight and Wednesday night) until thurday's cold front
helps to wipe out the associated lower level subsidence inversion.

Before that time the marine surge into the west side of
washington tomorrow will help kick up winds in some of the cascade
gaps late tomorrow afternoon and evening which will be highlighted
with some gusty wind and low relative humidity wording in the fire
weather products. Wednesday night into Thursday the high level
haines creeps up to 5 (moderate) over a large portion of the
cascades and remains that way until the front pushes through
Thursday afternoon (pushing the high level haines of 5 into the
basin). Winds should be breezy gusty with this vigorous cold front
passage Thursday so more liberal use of the same gusty wind and
low relative humidity wording gets utilized in the fire weather
forecast. Pelatti

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.
