Synopsis Rain showers will persist over the region this morning
before diminishing in coverage this afternoon. Isolated showers
may linger across the central coast tonight into early Thursday
morning yet most locations will remain dry. Another frontal system
pushes across the region on Friday with mainly dry weather
expected Saturday into Sunday. Unsettled weather returns for the
first half of next week along with seasonably cool temperatures.

Discussion As of 08:45 am pdt Wednesday... Latest radar imagery
shows the last of the main surge of precipitation is lifting
northeastward out of the north bay at this hour. Precipitation
totals came in close to previous estimates, with 1.00-2.00 inches
of rain over the higher terrain of the big sur and santa cruz
mountains, and generally around 1 4-1 2" (and locally higher) of
rain for most urban locations. That said, additional rainfall is
anticipated to fall in the form of scattered showers and
potentially an isolated thunderstorm or two through the day today,
though the majority of the rain from this system has passed. Peak
wind gusts, similarly, were on target with gusts late yesterday
ranging from 40 to 50 mph in the windier locations. Temperatures
are actually a few degrees warmer this morning versus 24 hours ago
owing to the higher dew points and nocturnal insulating cloud
cover, though daytime temperatures are expected to be below
seasonal normals for this time of the year (mid 50s to low 60s).

Speaking of this time of the year, spring officially begins at
258pm later today!
a secondary disturbance will traverse the backside of the broader
trough later today and into tonight which will spawn a secondary
weaker pulse of showery activity across the broader region. Short
term models continue to struggle defining where and when this
showery activity will develop, though the latest trends are
towards pulling rain farther offshore and mainly over the
orographically enhanced regions of the higher terrain and sierra
nevada inland. This means most lower lying urban areas should see
only lighter accumulations if any. These showers will pop up late
tonight and taper off through Thursday morning, mainly over the
higher terrain.

A transitory ridge will develop through most of Thursday with a
slight warming drying trend evident through the day. Another storm
system will arrive from the gulf of alaska by sunrise Friday,
impacting the north bay first before shifting southward throughout
the day Friday. Precipitation amounts will be highest over the
north bay and progressively lower the farther southward inland the
system progresses. A few lingering showers are possible into early
Saturday however most of the weekend will see a general
drying warming trend as another ridge passes overhead.

A third storm system will impact the region early next week. Mid
and long term models and ensemble members are peppering the mon-
wed period with various amounts of precipitation though there is
little consensus on the coverage or intensity of this rain.

Models do seem to be converging on the Monday morning timeframe
for an initial arrival time of the rains, though they disagree on
the duration or when if there will be breaks in the rain through
wed with the euro coming in noticeably wetter than other models.

See previous discussion for more information about the current
forecast package.

Previous discussion As of 03:48 am pdt Wednesday... Rain
showers are currently spreading inland across much of the region
this morning as a negatively tilted mid upper level trough
approaches the coast. Rainfall during the past 6 hours has been
greatest over the santa cruz mountains and along the santa lucia
range with 0.50" to 1.00" reported. Elsewhere, rainfall amounts
range from a few hundredths of an inch to around 0.25". Expecting
showers to spread northward through the remainder of the morning
before tapering off through the afternoon. While isolated showers
may linger into the late afternoon and evening, most areas will
see mainly dry conditions. A secondary short-wave disturbance
forecast to approach the coast late tonight into Thursday will
produce rain showers mainly offshore and over portions of the
central coast while most areas will remain dry through Thursday
night.

Another quick moving system will push a frontal boundary through the
region on Friday with light rain spreading from north to south.

Showers will then linger into Friday night before tapering off
Saturday morning. This will result in mainly dry conditions through
the first half of Sunday along with slightly warmer daytime
temperatures.

Medium range forecast models and ensemble members continue to
suggest a return to unsettled weather conditions during the first
half of next week. However, confidence remains low on the details
with respect to when, where and how much precipitation to expect.

Overall, look for periods of wet weather early next week with the
potential for more widespread rainfall and seasonably cool
temperatures.

Aviation As of 10:31 am pdt Wednesday... For 18z tafs. MVFR
conditions expected to continue into the afternoon with vis
temporarily reduced during heavier showers. The main band of
showers has already moved through this morning, but expect
scattered showers to linger into tonight. Additionally, there is a
slight chance of isolated thunderstorms today, but confidence is
low therefore vcts kept out of the tafs. Winds will continue to
gradually veer from out of the S SE to out of the W SW into this
afternoon and is forecast increase in speed through the early
evening. CIGS expected to lift toVFR late this afternoon and
become more scattered, although occasional bkn MVFR CIGS through
tomorrow morning will be possible.

Vicinity of ksfo... MVFR conditions to prevail through much of the
day along with scattered showers. CIGS will become more widely
scattered late this afternoon, but occasional MVFR bkn CIGS are
still possible into tomorrow morning. Showers will taper off this
evening and tonight. Patchy low CIGS possible around the bay area
tomorrow morning. SW winds to continue through late tonight with
winds gusting 20-25 kt this afternoon. Winds to diminish overnight.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... MVFRVFR conditions through the day with
rain rain showers impacting mry and sns. Winds will turn more
westerly through the rest of the morning and by mid-day. Showers
will linger into the late afternoon. Expecting CIGS to lift into
this evening.

Marine As of 08:45 am pdt Wednesday... Southerly winds will
continue to gradually veer out of the west over the coastal waters
this morning behind the cold front. A combination of west swell
and locally generated wind waves will allow for hazardous sea
conditions to continue today, particularly for smaller vessels.

Another west to northwest swell will arrive this weekend.
