A few inches of snow possible above 7000 feet. Showers possible

early next week. Slightly cooler temperatures for the second half
of the week but remaining dry and warmer than normal.

Discussion
Back edge of frontal band dropping southeast through northern
california now along a line from about blue canyon to modesto.

Precipitation amounts with this system have maxed out around 1
inch with around 1 2 inch common. The front will drop southeast of
the CWA by 18z. Models bring another shortwave system through the
pacific northwest this afternoon for a continued threat of
showers over the northern mountains through this evening.

Temperatures continue to cool today with daytime highs expected
to drop to about 10 to 15 degrees below normal. Upper ridging will
bring some warming on Saturday but another shortwave riding over
this ridge will bring another threat of light showers over the
northern mountains again through the day. The upper ridge
continues to build over the west coast on Sunday for more warming
with any precipitation threat being pushed well north of the
forecast area. Highs on Sunday with push upward to near normal for
this time of year. Daytime highs are forecast to climb another 5
to 10 degrees on Monday as the upper ridge amplifies along the
west coast.

.Extended discussion (Tuesday through Friday)
warm and dry conditions will dominate norcal during the extended
forecast period as high pressure lingers over the region. Daytime
highs will range 10-15 degrees above normal through Thursday.

Valley highs will remain in the mid to high 80s while the

gusty winds Monday in the western sacramento valley as the ridge
axis increases over the west coast. Hec jbb

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.
