Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... A 1028 mb high pressure center about 1000 miles west of cape mendocino will nudge closer to the coast through Monday. As a result, gusty northwest winds will continue over the coastal waters into midweek. Gale force gusts are most likely along the big sur coast Monday afternoon and evening. These strong northwest winds will generate steep fresh swell resulting in hazardous seas conditions. A long-period southerly swell will continue through Monday before swell periods begin to subside.

Area Forecast Discussion National Weather Service Sacramento CA 158 PM PDT Sun Jul 5 2020

SYNOPSIS. Dry weather with seasonable temperatures for the week.

DISCUSSION. Another hot and dry day is in store for interior NorCal. Early afternoon temperatures are around 2 to 5 degrees warmer than yesterday, especially in the northern Sacramento Valley thanks to a northerly wind. However, models indicate the winds will shift to the south to southwest in the Sacramento Valley this afternoon as the upper level pattern begins to flatten out over the area, bringing the return of onshore flow. This will keep afternoon high temperatures from rising too much more as they are expected to peak in the upper 90s across the Valley, though can't rule out a few locations reaching the century mark in the northern Valley if the winds don't shift as early as expected.

The upper trough slowly deepening over the area will cool temperatures a few degrees and allow onshore flow to continue through midweek, though dry weather will remain. Daytime temperatures will hover right around normal through midweek. Valley highs are forecast in the 90s with upper 60s to 80s in the mountains.

A shortwave is expected to move through NorCal tomorrow which will bring gusty winds to the area. Strongest winds are expected in the Delta region and over the Sierra crest with westerly wind gusts up to 30 to 40 mph. Fire weather concerns are low with these winds as humidities will be increasing somewhat because of the onshore flow. However, grasses are cured in the Valley and lower foothills, so fire safety should always be practiced during this time of year. HEC

EXTENDED DISCUSSION (Thursday THROUGH Sunday). Ensembles continue to indicate an upper level trough deepening over the eastern Pacific Thursday with strong high pressure over the Central US. Overall the forecast for the end of the week is similar to previous days with continued onshore flow and near normal temperatures. Ensembles then indicate the monsoon high pressure developing over the Desert SW Friday into the weekend. This high pressure looks to build west through the weekend, raising heights over NorCal and causing temperatures to rise for the weekend. At this point, Valley temperatures are forecast in the upper 90s to low 100s for the weekend with mountain temperatures in the 70s to 80s. HEC

AVIATION. VFR conditions continue the next 24 hours. Winds remain under 10 knots into the overnight except in the Delta where gusts up to 25 knots will be possible after 0z. Breezy west and south winds tomorrow with strong winds up to 35 knots in the Delta.

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.
