area forecast discussion
national weather service san francisco bay area
1056 pm pdt Sun may 26 2019

Synopsis Scattered showers are possible through this evening,
mainly south of san francisco. Dry but cool conditions are
forecast for memorial day. A gradual warming trend is expected
over the next few days with temperatures expected to return to
near normal by midweek. Dry conditions are forecast for the
remainder of the week and into next weekend.

Discussion As of 8:55 pm pdt Sunday... An unseasonably cold
weather system produced scattered showers late last night and
today, with the most numerous showers occurring across southern
portions of of our forecast area. There was also an isolated
thunderstorm early this afternoon near gilroy in the southern
santa clara valley. A few locations in the hills of northern
monterey county picked up slightly more than a half inch of rain
over the past 24 hours, otherwise rainfall amounts were mostly
less than a quarter inch. The monterey climate station accumulated
0.22" of rain in the past 24 hours, boosting its monthly total to
2.77", which makes the current month the wettest may on record in
monterey. The previous record for may was 2.67" in 1998 (monterey
rainfall records go back to 1949).

Shower activity has been ending from north to south since early
afternoon as the upper low moves off to the southeast. Current
kmux radar shows only isolated showers across the southern half of
our area. Based on the 00z NAM and latest hrrr, a few showers may
linger across the southern portion of our area until late tonight,
but dry conditions will return to all areas by Monday morning.

Memorial day is forecast to be a dry and partly cloudy day with
highs mostly in the 60s to around 70. Tomorrow's temperatures will
be about 5 degrees warmer than today, but still well below normal.

The upper trough currently centered over california is forecast to
shift eastward over the next few days while an upper ridge over
the eastern pacific edges closer to the west coast. In between,
our area will be under dry northwesterly flow aloft with
gradually increasing heights. This will result in warming through
midweek. By Wednesday, temperatures are forecast to return to near
seasonal averages for the first time in several days.

Although dry weather is currently forecast through the week, a
couple of weak disturbances moving through the northwesterly flow
aloft could produce brief light precipitation in california at
times this week. Currently, precipitation potential looks to be
confined to areas to our east.

Longer range models indicate the upper ridge over the eastern
pacific will finally build eastward over california by next
weekend. Thus, we may see warmer than normal temperatures develop
next weekend, or early in the following week.

Aviation As of 10:56 pm pdt Sunday... Scattered showers remain
this evening, mainly south of sf bay. The upper low which caused
more widespread showers and isolated thunderstorms earlier in the
day is departing to our southeast, and showers will continue to
decrease in coverage overnight. A few isolated showers may linger
near the monterey bay terminals into early Monday morning before
ending completely. A mix ofVFR MVFR currently with MVFR
conditions becoming more widespread overnight and into Monday.

Models at this time do not bring much clearing Monday afternoon so
could see CIGS continuing through most of Monday. Light winds
overnight becoming onshore with 10-15 kt on Monday afternoon.

Vicinity of ksfo... Showers have generally ended for the night at
the terminal. Expect CIGS of 1500-2500 feet overnight continuing
through Monday morning. CIGS expected to lift to 2500-3500 Monday
afternoon but may not completely erode. West winds 5-10 kt
overnight with 10-15 kt and gusts to 20 kt Monday afternoon.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Vcsh through the overnight hours with a
few isolated showers possibly lingering into Monday morning. Cigs
of 1000-2000 feet expected overnight through Monday morning. MVFR
likely to persist into Monday afternoon with CIGS of 2000-3000
feet.

Marine As of 8:44 pm pdt Sunday... Low pressure moving inland
across california will bring breezy northwest winds through
tonight. Winds will decrease on Monday morning before becoming
breezy again Monday afternoon. Northwest winds will strengthen
further and become breezy to gusty on Tuesday and Wednesday.

Moderate northwest swell continues into the upcoming week with
steep fresh seas generated by gusty winds.

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.
