Synopsis Seasonably mild conditions will persist through
Tuesday. A frontal system will move through the region late
Wednesday and may produce light rain over the northern portions of
the north bay. Post-frontal breezy conditions and cooler
temperatures are expected from late Wednesday through Thursday and
may persist into the upcoming weekend.

Discussion As of 03:27 am pdt Monday... Patchy low clouds
persist along portions of the coast this morning and have spread
locally inland down into the salinas valley. Meanwhile, more
widespread fog is being reported over the sonoma valley with
temperatures ranging from the middle 40s to lower 50s region-wide.

This is in response to a mid upper level trough over much of the
west coast. Low clouds and fog will begin to dissipate after
sunrise with temperatures warming into the 70s to lower 80s inland
this afternoon. Coastal locations will likely only warm into the
upper 60s to lower 70s as onshore flow persists.

Temperatures look to warm by a few degrees heading into Tuesday
as a weak short-wave ridge will move over the region in wake of
the exiting mid upper level trough. Conditions will cool slightly
over the northern portion of the region on Wednesday in advance of
an approaching weather system. The core of this system will push
inland over the pacific northwest and drive a weak frontal
boundary into northern california late Wednesday into Wednesday
night. Thus, a slight chance of rain remains in the forecast for
the north bay. However, measurable rainfall south of northern
sonoma county appear unlikely as the frontal system dissipates
Wednesday night into Thursday morning. This system will also
result in cooler temperatures region-wide through late week.

In addition, locally gusty post-frontal northwest winds are
expected Wednesday into Thursday, primarily in coastal locations.

Breezy conditions will likely continue through late week and
potentially into the upcoming weekend with temperatures near to
slightly below seasonal averages. Ongoing dry weather conditions
are also likely to persist late in the forecast period.

Aviation As of 10:35 pm pdt Sunday... For 06z tafs. Patchy low
clouds continue to develop along the coast with some inland
intrusion visible on satellite. Gradual deepening of the marine
layer and expansion of coastal stratus will bring patchy low
clouds to coastal terminals overnight. However, it may be one of
those night where the stratus moves in and out bringing tempo cigs
to the some terminals. Light and locally variable winds will
prevail overnight.

Vicinity of ksfo...VFR conditions will prevail through the
forecast period with patchy low clouds likely peeking through
coastal gaps early Monday morning. Light and locally variable
winds will prevail overnight.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals...VFR conditions will prevail through late
tonight. Patchy low clouds may bring temporary CIGS to area
terminals between 07z and 14z early Monday morning. Light
offshore or locally variable winds expected overnight.

Marine As of 03:27 am pdt Monday... Generally light northwest
winds will prevail over the coastal waters through columbus day.

Mixed seas will continue over the next few days with a light
shorter period northwest swell and a light southerly swell. A
larger northwest swell is forecast to arrive later this week with
forerunners expected in the next couple days.

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.
