Synopsis
Hot and dry weather today. Widespread triple heat across the
valley this weekend. A little cooler next week. Slight chance of
sierra thunderstorms Sunday afternoon and into early next week.

Discussion
High pressure aloft over the southwest u.S. Bringing fair skies
to the CWA this morning with temperatures running just a bit
higher that 24 hours ago. Upper ridge is forecast to back eastward
over the state today bringing a warm up of several degrees. The
northern sacramento valley could see daytime highs today near 110
degrees. Will leave the heat advisory up as is with heat risk
criteria still being met. Sub tropical moisture and instability
appear to remain south of the forecast area today so have left
any shower or thunderstorm out of the forecast for now. Models in
good agreement in moving a weak upper low in off the north coast
on Sunday. More onshore flow and a slight airmass cooling will
bring slightly cooler temperatures. Bigger impact may be push of
sub tropical air northward up the sierra crest. GFS shows
instability along the crest as well so an afternoon slight
thunderstorm chance along the sierra crest seems a reasonable
forecast threat. Upper low digs a bit farther southward on Monday.

Southeast flow aloft will continue to bring moisture and
instability up the sierra crest so thunderstorm threat continues.

More airmass cooling should drop daytime highs most valley
locations down to below the century mark. Upper low remains
centered around the north coast on Tuesday bringing still more
cooling. Daytime highs next Tuesday are forecast to drop to near
or even a little below normal. Upper level southerly flow will
continue to bring afternoon and evening thunderstorm threat up the
sierra and cascade crest.

.Extended discussion (Wednesday through Saturday)
computer models have come into better agreement with the handling
of the offshore upper low, with the GFS and ECMWF now pushing the
system inland on Wednesday. As such, thunderstorm chances should
continue across norcal mountains through midweek. Drier weather
ensues toward the end of next week with a slight warming trend and
forecast temperatures a few degrees warmer than normal.

Aviation
MainlyVFR conditions the next 24 hours across interior norcal,
except reduced visibilities in smoke near the detwiler fire. Winds
will remain light today, except gusts to 25 kt near the delta and
over higher terrain.

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.
