Synopsis
Widespread shower activity today with snow being forecast for the
higher sierra elevations. Afternoon mountain showers or
thunderstorms continue through next week, with highs returning to
near normal by Tuesday.

Discussion
Satellite imagery this afternoon shows a broad low pressure system
churning over california. This system has brought widespread
showers to the region including a few isolated thunderstorms to
the northern san joaquin valley. Most of the thunderstorm
activity has been south of the cwa, but that doesn't mean we're in
the clear just yet. Convective parameters from model guidance and
the SPC mesoscale analysis page show that at least the southern
portion of the sacramento valley, northern san joaquin valley, and
the eastern foothills all still have a chance for tstorm activity
this afternoon and evening. The other area of concern with these
cool convective showers is how much they'll cool the airmass.

Spotter reports and posts to social media from cedar ridge and
arnold show that snow levels have been able to dip to around
4800-5000 ft for the southern portion of zone 69. Not much is
expected in the way of accumulation, but it is possible for some
snow to stick on trees and some grassy surfaces. Farther up the
mountains, accumulating snow is still in the forecast for
elevations above 5000-6000 feet thus the winter weather advisory
remains in effect.

As the low exits the region on Monday, mountain showers will
become more isolated and scattered in nature. Elsewhere, dry
conditions are anticipated. In terms of temperatures, highs will
be as much as 5 to 15 degrees below normal for Monday before
becoming seasonal on Tuesday.

.Extended discussion (Thursday through Sunday)
long wave trough remains near 120w through the extended period
with mainly weak short waves tracking through. This will keep an
unsettled weather pattern with a threat of showers and afternoon
thunderstorms. Best chances will be over the eastern foothills and
mountains. High temperatures expected to be close to average for
late may.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

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.
