area forecast discussion
national weather service sacramento ca
330 am pdt Tue oct 16 2018

Synopsis
Warm and dry weather continues this week. Locally gusty easterly
winds continue in the sierra and foothills this morning.

Discussion
Satellite imagery indicates the area of stronger subsidence has
shifted south. Easterly pressure gradients remain tight (rno-sac
is around 8.5 mbs), but a little weaker compared to 24 hours ago.

Still seeing local wind gusts in the 30-50 mph range across the
northern sierra west slopes and foothills.

Dry weather with mild days and cool nights will continue through
the week as the ridge over the eastern pacific moves onto the west
coast. Enough easterly gradient lingers tonight for continued
locally breezy conditions in the sierra, but likely weaker than
the past couple of nights.

.Extended discussion (Saturday through Tuesday)
weekend starts out with a rex type block pattern over the west
coast with upper level high pressure ridge over the pacific
northwest and norcal and a low off the socal coast. Daytime highs
Saturday and Sunday will remain a few to several degrees above
normal with relatively low humidity but winds should be relatively
light. Upper ridge is forecast to shift inland early next week
bringing a cooling trend down to slightly above normal. A weak
pacific storm system is forecast by the ECMWF to bring a threat of
precipitation to the northern CWA next Tuesday. GFS keeps this
system a bit farther north keeping any precip threat north of the
forecast area. Both models have been consistent with their
solutions over the last couple runs but model to model discrepancy
brings low confidence in end of extended forecast. For now, took
a middle of the road approach keeping precipitation chances low
for this time frame. Either way, slightly more cooling should
bring daytime temperatures down to normal.

Aviation
Vfr conditions next 24 hours. Winds generally below 12 kts at taf
sites with local NE to E surface wind gusts up to 25 to 30 kts
over eastern foothills and sierra nevada through 18z.

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.
