Synopsis
Rain and snow will linger over the idaho panhandle overnight
leading to further heavy mountain accumulations. It will be windy
overnight and into Wednesday with gusts to 40 mph over the
palouse. A series of weather systems Thursday through the weekend
will bring the potential for a mix of rain and snow in the
lowlands and snow over the mountains.

Discussion
Winter weather advisories have been taken down across the northern
portion of the upper columbia basin to the coeur d'alene area and
down on the palouse. The idaho palouse zone was cancelled early as
it looks like the valley locations have warmed up to the point
that the snow has switched over to rain. There is a change that
the precip will switch briefly back over to snow with the cold
front passage, but not enough to be a significant enough issue to
keep highlights going for these areas. No changes have been made
to the winter storm warnings. The next area that will likely see
snow end will be the okanogan highlands and I anticipate that this
advisory will be able to come down on schedule as the cold front
is tracking as advertised. Svh

Aviation
00z tafs:
a cold front will sweep across the region this evening with
precipitation filling back in across eastern wa. This will lead to
a period of light -fzra at keat and a mix of rain snow across the
spokane coeur d'alene corridor. A strong low level jet across the
basin and into eastern wa and the id panhandle will also result in
low level wind shear with south-southeasterly winds at the
surface turning westerly 40-55 kts at the top of the mix layer between
15-25 kft agl. Cold front will reach the id panhandle between
06-08z. Strong westerly winds will then mix down to the surface.

Difficult to say how much low clouds will be around after midnight
due to the strong mixing, but also a moist boundary layer.

Leaning toward a stratus deck with MVFR conditions at kgeg, ksff,
kcoe and kpuw through late tonight, but too much wind for any fog.

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.
