Synopsis
Lingering mountain showers today then another storm moves
through Sunday into Monday. Drier Tuesday followed by a threat
of another storm midweek.

Discussion
Some lingering showers over the mountains will end by 7 pm this
evening per the hrrr. The next system will start to spread some
light precipitation over the area first late tonight up north than
mostly over the mountains during the day with chances of showers
for the valley. Precipitation chances increase Sunday night when
the heaviest precipitation is expected to occur.

Models indicate lingering showers on Monday for the western
slopes before ending Monday evening. Monday morning is when the
snow levels will be the lowest and likely below 4000 feet, but
by then the system will be near its end. 3-6 inches of new
snowfall above 4000 feet with up to 10 inches across the peaks
looks possible.

Rainfall amounts for the valley will be less than a quarter inch
to one half to an inch for the foothills and mountains.

Northerly winds will develop for Monday and Tuesday and may be
breezy. After a couple of cool days temperatures will warm into
the 70s on Tuesday in the valley and 50s in the mountains.

.Extended discussion (Wednesday through Saturday)
high pressure is expected through most of the extended period.

High temperatures will rise into the mid 70s in the valley and
50s in the mountains starting Wednesday. A brief shortwave trough
will push a surface cold front into the area on Thursday,
dropping temperatures by around 5 degrees and possibly bringing
light precipitation to the northern portions of the area and the
sierra. Otherwise, warm and dry weather with breezy northerly
winds will persist through the end of the week. Hec

Aviation
Vfr conditions expected at TAF sites with light winds less than
10 kts. Rain moves into the region Sunday after 18z.

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.
