Synopsis
Weak weather systems will bring light precipitation through
Wednesday. Gusty north winds develop late in the week.

Discussion
Break in precip across interior norcal early this morning as
short-wave ridging from the eastern pacific begins to build in.

However, skies remain partly to mostly cloudy across the region as
deep moisture continues to stream across the pacific. Current
temperatures are generally in the 30s in the mountains with 40s to
lower 50s elsewhere - slightly cooler in most areas compared to 24
hours ago.

The next system will move into the pacnw today, however some
showers will make it far south as the northern mountains and
northern coast range. Another system will follow quickly on its
heels spreading shower chances further south later tonight and
Wednesday. Only light amounts of QPF are forecast and snow levels
will rise to above 8k feet, so expect little or no impact to
travel across the northern sierra passes.

Stronger ridging from the eastern pacific builds over the area
bringing a return of dry weather along with warmer temperatures as
highs are expected to return to close to average for late april.

Breezy northerly winds will also develop across the region.

.Extended discussion (Saturday through Tuesday)
high amplitude upper ridging in the epac extends over interior
norcal through the weekend resulting in dry conditions with above
normal temperatures. Breezy northerly winds from Friday continue
into Saturday. Ridging weakens over northern portions of ca Monday
as a short wave trough digs through the pacnw into the great
basin. This will result in minor cooling over northern portions of
the forecast area. High pressure rebuilds behind the wave Monday
night into Tuesday resulting in a return of breezy northerly wind.

Low level CAA with this flow will offset downslope warming and
maintain slightly cooler temps of northern portions Tuesday.

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.
