area forecast discussion
national weather service sacramento ca
855 am pdt Tue jun 27 2017

Synopsis
Near average temps thru mid-week followed by a warming trend.

Discussion
15z temps running very similar to yesterday as the patchy early
morning stratus erodes dissipates. Noticeable changes taking place
as the delta breeze weakens, e.G. Suu now 15kts compared to 23g29kts
yesterday. Considering the weakening delta breeze, today will be a
little warmer, especially in the delta influenced areas. Hourly
updated lav guidance running just slightly cooler than our forecast
maxes today, but probably not worth an update as the temps are
expected to be within a couple of degrees or so of the forecast
highs, unlike yesterday which trended several degrees cooler than
forecast.

Yesterday's short wave trof is nor over id and moving farther away
allowing flat ridging to build in its wake. However, a weak trof
will move into the pac NW today with a weak short wave moving across
norcal early this evening. Hence, the delta breeze should increase
again, but likely not as strong as the recent past. Marginal
instability forecast over the NRN mtns, mostly over the trinity alps
and siskiyous where short-lived convection may materialize, just n
or our cwa. Jhm
warming returns wed-fri as ridging over the eastern pacific moves
onto the west coast. This will suppress the marine layer weakening
onshore flow and result in modest synoptic warming. Triple digit
heat will likely return to the northern sacramento valley thu-fri.

.Extended discussion (Saturday through Tuesday)
dry weather is expected to continue through the extended period.

A weak upper trough is projected to move through northern
california on Saturday, bringing a brief cooldown. Otherwise,
temperatures through the extended period should remain on the
order of 5-10 degrees warmer than normal. Dang

Aviation
Vfr conditions the next 24 hours. South to west winds 5 to 15 kt
will continue today, with afternoon gusts up to 25 kt possible.

Near the delta... Sw wind gusts up to 30 kt expected. Dang

Sto watches warnings advisories None.

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.
