Synopsis
A storm system will bring snow later today through Wednesday with
heavy snow accumulations over southeastern washington and lower
idaho panhandle. Another round of snow is likely by the end of the
week into the weekend as cold temperatures persist.

Discussion
Some significant changes to the snow amounts were made with this
ongoing winter storm moving into the region. Not much more snow is
expected across the northeast mountains and into the northern
panhandle with drier air moving in. Radar returns have shown a
decreasing trend up across this area. Models are in good
agreement with a surface low spinning up east of the cascades over
southern wa right now (10 pm). Satellite image shows a cellular
looking cloud pattern west of the cascades indicating very cold
and unstable air. As this cold shifts in over the region, we will
see our lapse rates steepen considerably with high snow ratios
under more convective snow showers. Higher resolution convective
allowing models indicate an axis of moderate to heavy snow bands
developing on the northern fringe of the surface low from around
moses lake to ritzville to pullman. I added the moses lake area to
the winter weather advisory with a couple inches of snow expected
overnight into Wednesday morning. I only expected up to another
inch of additional snow for the coeur d'alene area and downgraded
this area to an advisory from a warning. Svh

Aviation
06z tafs: a stratiform shield of light snow will fall across the
spokane coeur d'alene corridor down to the palouse and l-c valley
and into the idaho panhandle into the overnight period. Snow is
expected to become more convective in nature late tonight into
Wednesday morning as colder and more unstable air moves in. A
surface low developing over southern wa will supply the lift with
bands of moderate to heavy snow developing on the northern portion
of the low. These bands are expected with the area from keat to
kykm to klws and kgeg. Snowfall rates within these bands could be
as much as 1 inch per hour. Pullman will continue to see snow
showers into Wednesday afternoon with low ifr conditions until
then. Svh

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.
