area forecast discussion
national weather service san francisco bay area
926 am pst Mon jan 21 2019

Synopsis Residual showers are expected to continue this morning
as a cold upper level low exits the area. Dry conditions are
expected to prevail districtwide by mid morning. Dry weather,
cool overnight temperatures, and progressively warmer days are
then forecast through the end of next weekend as strong high
pressure builds over the west coast.

Discussion As of 08:50 am pst Monday... Lingering showers over
portions of the central coast continue to diminish in coverage
this morning and should come to an end in the next hour or two.

Meanwhile, sky conditions have cleared for much of the san
francisco bay area northward where temperatures cooled in the the
30s for the colder inland valley locations with 40s for the
remainder of the region. Seasonably cool and breezy conditions
will persist today with most locations warming into the 50s. With
this said, the ongoing forecast remains on track and no updates
are anticipated at this time.

Prev discussion As of 3:00 am pst Monday... Kmux continues to
show some shower activity from about santa cruz southward as the
cold upper level trough edges eastward. These residual showers
will persist early but decrease during the morning. By this
afternoon, dry and cool conditions will settle in. Highs today are
expected to be cool and generally in the 50s.

As an upper level ridge begins to build over the eastern pacific,
a surface high will build into the great basin. This will result
in some gusty winds tonight mainly over the north bay mountains
and east bay hills. Strongest winds are anticipated to be limited
to just the higher elevations, thus, a wind advisory isn't
expected to be needed. This gradient will relax on Tuesday, and
high pressure will bring warmer temperatures to the district by
Wednesday, when highs are forecast to warm into the 60s. This
trend will continue through the week with warmest inland areas
likely see highs warming into he 70s. This ridge will remain
anchored along the coast through the week keeping dry conditions
then through the period.

showers continue to linger around the southern portion of the
region this morning. Expect showers to diminish over the next

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
