The strongest winds will occur off of the big sur coast where gale force gusts are likely through this evening. These strong winds will continue to generate steep fresh swell and hazardous seas conditions. Winds will begin to diminish late in the week.

Area Forecast Discussion National Weather Service Sacramento CA 201 PM PDT Tue Jul 7 2020

SYNOPSIS. Dry weather with seasonably warm temperatures for the week.

DISCUSSION. A trough of low pressure passed through the region last night and now a more zonal flow pattern will set up the next couple of days. Flow through the Delta will be weaker which will allow for temperatures to warm several degrees the next several days. Another trough will start to deepen off the Pacific Northwest late Friday that may help to increase flow through the Delta Friday night.

EXTENDED DISCUSSION (Saturday THROUGH Tuesday).

A trough will deepen slightly and move closer to the Pacific Northwest coast by Saturday. This should help to keep stronger flow through the Delta this weekend and maybe cool the Sacramento region by a few degrees otherwise most other locations should not be changing that much through the weekend. Little change is expected the first part of next week with continued breezy conditions through the Delta and warm inland.

AVIATION.

VFR conditions the next 24 hours. Wind remain under 10 knots except for in the Delta where gusts up to 25 knots are expected.

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.
