Synopsis
A weather system passing through the inland northwest this morning
will bring light to moderate accumulations of snow to northeast
washington and the idaho panhandle especially over higher
elevations as well as near the cascade crest. An active but
relatively mild weather pattern will persist through the next week
with more mountain snow and generally rain or light accumulations
of wet snow in the valleys.

Discussion
Morning update: a warm front passing through eastern wa N idaho
this morning will continue to lift north and east through the
morning. The forecast has been updated based on latest radar
trends. For the remainder of this morning additional precipitation
will be focused over the idaho panhandle and extreme NE washington
as drier air is moving in from the southwest. Snow levels are near
the valley floors but accumulations should not last long in the
valleys as temperatures rise above freezing for most areas by late
morning. Moist upslope into the cascade crest will generate
additional snow as well but strong downslope flow off the cascades
will focus most of this snow near the crest. Current winter
highlights going through noon look in good shape as snow levels
rise behind the warm front in the afternoon. Jw

Aviation
18z tafs: a warm front will continue to lift north and east this
morning with increased drying in the boundary layer from the
south.VFR conditions have already developed at all TAF sites
except kcoe but the drier air will move into here by 20z. For
keat... Greater protection of the dry air could allow patchy fog to
develop late tonight but with most guidance leaning away from this
kept conditionsVFR. Winds will be occasionally gusty out of the
south with gusts 15-20 kts, locally stronger of 20-25 kts kpuw klws
with a stronger pressure gradient in this area. Jw

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
