Synopsis
Dry weather into next week with mild days and chilly nights.

Discussion
Strong upper high continues over the west with dry weather, chilly
nights, and mild days. Afternoon temps running from 0 to 7 degrees
warmer than 24 hours ago... Warmest in the northern sacramento
valley. Krdd currently at 72 which already breaks the previous
record of 71, set in 2012. The city record is 74 which was set in
1925. Krbl is reporting 70 this hours which is two degrees below
the record.

Upper high shifts slightly east Monday into Tuesday as short wave
trough rides the ridge towards b.C. Ridge then retrogrades back to
the west coast Wednesday with dry weather persisting. Some
morning patchy fog or frost will continue to be possible in the
central valley over the next several days. Highs temperatures will
continue to be above normal through midweek with record highs
possible in portions of the northern sacramento valley.

Pch
.Extended discussion (Thursday through Sunday)
interior norcal will remain under a dry airmass with above normal
temperatures as a ridge of high pressure remains in control.

Upper level ridging is progged to weaken and retrograde offshore
as a shortwave trough moves through the west coast late this week.

However, the forecast area will likely remain dry. Locally breezy
north winds will be possible as the system moves through. Beyond
that, guidance indicates a series of disturbances coming down the
ridge but it appears that there will be no precipitation chances
through at least next weekend.

Aviation
Vfr conditions over interior norcal next 24 hours except for
MVFR ifr vsbys possible in br fg over the central valley between
08z-18z Tuesday. Surface winds generally below 10 kts.

Sto watches warnings advisories
None.

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.
