Synopsis
Breezy north winds will continue in the sacramento valley before
decreasing later today. A chance of showers for the region around
mid-week, otherwise dry conditions through the end of next week.

Discussion
Other than a few high clouds passing overhead, skies are clear
across the region early this morning. Gusty northerly winds
continue in the sacramento valley with local gusts of 35-45 mph
still occurring in the vacaville and fairfield area. Easterly
surface gradients have increased compared to 24 hours ago (rno-sac
is currently around 9 mbs) resulting in locally gusty winds across
the northern sierra nevada and foothills.

Northerly winds will decrease later this afternoon as the upper
ridge builds over the region and surface pressure gradients relax.

A fast moving weather system will brush through the region Tuesday
night into Wednesday and may bring several inches of snow to the
mountains with minimal QPF in the valley. Colder air moving over
the region may keep daytime highs in the 50s for the valley to the
30s for the mountains.

.Extended discussion (Thursday through Sunday)
dry weather returns for late-week behind the exiting trough with
gusty north winds likely to develop through the central valley in
its wake.

Aviation
Vfr conditions next 24 hours. Northerly wind gusts 20-30 kts will
continue in the sacramento valley thru about 00z Monday.

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.
