Synopsis
A strong weather system will bring moderate to heavy snow
accumulations tonight to much of the area with only the deeper
portions of the western columbia basin escaping with minor
overnight accumulations. Breezy and unsettled conditions will
continue through Wednesday. Expect generally dry weather with
occasional fog and seasonable temperatures from Thursday through
the weekend.

Discussion
Today through Thursday: our widespread winter storm is exiting the
region early this morning. The heavy band of snow has moved east
of our region. I will be gradually taking down the warnings and
advisories, starting with spokane and the palouse. The panhandle
and northeast wa warnings will end at 4am, with the central
panhandle warning continuing through the day.

A secondary band of rain and snow will move down from canada
across the panhandle and extreme eastern wa, but any additional
snow accumulations from this band will be very light.

High pressure will build into the area quickly today. I don't
expect much wind in the valleys today. As such, we should have a
fairly moist atmosphere tonight, which coupled with the clearing
skies, should result in the development of fairly widespread fog
and low clouds overnight. These will persist all day on Thursday
over most of the lower elevations, with sunshine in the cascades.

Rj
Thursday night to Tuesday: the weather pattern becomes
relatively quiet as the region will be dominated by a west to
northwest flow, with a ridge of high pressure building along the
west coast. A couple shortwave disturbances pivot by in that flow,
the first around Thursday night into Friday and the second toward
Sunday or Sunday night. The first wave brings snow shower chances
along the wa id border counties eastward. Precipitation looks
relatively light but some minor impacts are possible through the
panhandle mountains. The threat retreats into the idaho panhandle
mountains by Friday evening and wanes. The second wave brings the
next precipitation threat to the cascades, north-central and
eastern wa and id Sunday. Outside of the mountains the
precipitation threat looks limited. This system looks relatively
mild with mountain snow and valley rain snow mix, but overall
precipitation looks light. Some blustery conditions come in later
Sunday into Sunday evening on the backside of this wave, which
ushers in another cooling trend. Another system will nose toward
the region going into later Tuesday (into next Wednesday).

Otherwise expect dry conditions with some areas of low clouds and
patchy fog in the overnight morning hours. Cote’

Aviation
12z: snow will be ending at the geg sff coe airports early this
morning. An additional band of rain and snow will move through
these airports later this morning for continued ifr conditions
until mid day. Expect lifr fog and low clouds to form tonight and
persist into Thursday. Dense fog at keat and kmwh should also
burn off this afternoon, but will reform overnight tonight. Kpuw
will probably maintain a low cloud deck for much of today and
tonight. Rj

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.
