330 am pdt Wed apr 26 2017

Synopsis
Weak weather system will bring light precipitation today. Dry
with gusty north winds developing late in the week.

Discussion
Clouds and even a few light showers have been increasing across
interior norcal overnight as the latest weather system moves into
the region. Current temperatures are considerably milder compared
to 24 hours ago and generally range from the mid 30s to mid 40s in
the mountains with mainly 50s elsewhere.

Only light amounts of precipitation are expected across the region
into this evening as the system slides down in west-northwest flow
over the eastern pacific ridge. Rain totals in the valley will
likely only amount to a few hundredths of an inch while some
northern sierra locales may see between a quarter and half an
inch. Snow levels will be above 8k feet through the event, so
little or no impact to travel expected through the higher northern
sierra passes.

Amplifying upper air pattern forecast across western north america
beginning Thursday as the trough deepens to our east around the
four corners region by Saturday while upstream ridging over the
eastern pacific edges onto the west coast. This will bring a
return of dry and milder weather to interior norcal along with
periods of breezy north winds to the central valley.

.Extended discussion (Sunday through Wednesday)
high amplitude upper ridging in the epac extends over interior
norcal through the weekend resulting in dry conditions with above
normal temperatures. Ridging may weaken some over northern
portions of ca Monday as a short wave trough digs through the
pacnw into the great basin. This could bring minor cooling over
northern portions of the forecast area Monday. High pressure
rebuilds behind the wave Monday night into Tuesday resulting in a
return of gusty northerly wind. Breezy conditions continue into
Wednesday as ridge axis shifts inland and temperatures increase to
upwards of 15+ degrees above normal.

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.
