area forecast discussion
national weather service sacramento ca
330 am pdt Wed jul 17 2019

Synopsis
Dry weather with seasonably hot temperatures continue, gradually
cooling by late this week. Breezy winds through the delta and
over the sierra crest at times.

Discussion
Not much change in the overall pattern as a weak trough lingers
along the west coast into the weekend. Therefore, dry conditions
and seasonably hot temperatures will continue. Temperatures in the
delta breeze influenced areas will vary slightly day-to-day
depending on the depth of the marine layer and strength of onshore
flow.

Extended discussion (Sunday through Wednesday)
Current extended forecast remains dry as norcal remains under the
western portion of a strong high pressure ridge over the western
u.S. Should see fairly stable conditions under upper southwest
flow between this high pressure ridge and troughing over the
eastern pacific. Operational GFS has been hinting at bringing
monsoon moisture up the sierra in more southerly flow for some
possible sierra thunderstorms early next week. GEFS ensemble
members not really backing up this idea at this time so have kept
sierra afternoon thunderstorms out of the forecast. With norcal
being under the western fringe of the western u.S. Ridge, the cwa
will not see the full effects of subsidence warming and as a
result, daytime temperatures through the extended will stay near
or just slightly above normal with no heat wave expected. Winds
should remain fairly light except for occasionally breezy through
the delta and over the sierra crest.

Aviation
Vfr conditions next 24 hours. Southwest wind gusts 20-30 kts
vicinity delta; otherwise, sustained winds generally below 15
knots.

Sto watches warnings advisories None.

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.
