Synopsis
After a dry but cloudy Saturday, another weather system will bring
more snow on Sunday. A warm and wind weather system will arrive on
Tuesday into Wednesday bringing the potential for heavy mountain
snows and mix of rain and snow in the lower elevations. The
weather will then be dry and cold for the remainder of the week.

Discussion
Morning update: snow has exited the region. A drier northwest flow
is delivering sunshine across the northern mountains. Slightly
different picture for the cascades which is being infiltrated by
mid and high level moisture as the next storm system approaches
the coast. Meanwhile, valleys are plugged with low clouds. On the
higher benches, these low clouds are touching the ground resulting
in dense fog. I think we will see some clearing of the low clouds
around the northern valleys and east slopes but confidence is low.

Aviation
18z tafs: all terminals experiencing ifr stratus this morning.

Expect CIGS to lift a little later this afternoon. There is a
drier NW flow above the boundary layer but confidence is low how
much this can erode the low clouds. Based on regional cams,
thinking keat will stand the best shot for this to break up. Cigs
to lower again this evening but boundary layer winds do start to
increase from the south tonight ahead of the next storm system.

This could lead to some clearing from south to north for locations
like klws, kpuw, kmwh, keat. Otherwise, top down moistening to
bring -sn to the terminals 10-14z. Very little precipitation
expected for kmwh keat so went with vcsh but these areas may see
brief mix of sleet freezing rain with only trace amounts. Sb

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
