area forecast discussion
national weather service sacramento ca
1010 pm pdt Sat sep 23 2017

Synopsis
Warmer and drier into next week with breezy north winds.

Discussion
Air mass decoupling with nocturnal cooling and formation of the
radiative inversion has allowed nly winds to subside. 925 mbs winds
10-18 kts on the lee-side of the coastal range forecast overnite
with the highest winds in the lake co area which will keep rhs low
(recover poor) maintaining rfw conditions. Modest nly winds expected
on Sun will keep rh low again with redevelopment of the nly barrier
winds again Sun evening on the west side of the sac vly and lee side
of the coastal range. Jhm
a ridge of high pressure will build over the region and remain in
place through midweek. Little change in winds expected the next
couple of days with northerly winds in the valley being the
strongest during the day and easterly winds in the mountains being
the strongest at night and in the morning hours. Temperatures
will warm a little each of the next several days topping out in
the 90s by the middle of next week.

.Extended discussion (Wednesday through Saturday)
an upper ridge of high pressure over the epac will nudge towards
the pacific northwest and build over the area by mid-week. As a
result, dry conditions and above temperatures are expected across
interior norcal. Meanwhile, an upper level low will develop over
the great basin and retrograde over southern california. This will
act to limit warming over the region to some extent. However,
daytime highs will likely remain 5-10 degrees above normal in the
extended period. By the end of the forecast period, the ridge will
slowly be displaced as a trough approaches the pacific northwest.

A portion of that upper energy could extend into our area and
keep temperatures from trending upward as indicated by the ecmwf
but the GFS keeps the area warmer.

Aviation
Vfr conditions expected for valley TAF sites for the next 24
hours. Breezy valley winds will increase Sunday afternoon after 18z.

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.
