Synopsis Isolated showers will be possible across the region
through early afternoon, especially along coastal areas of the
central coast. Dry conditions develop tonight ahead of the next
frontal system that will bring widespread rainfall to the region
Friday into Friday night. Mainly dry conditions return for a
majority of the weekend with unsettled weather likely throughout
at least the first half of next week.

Discussion As of 08:34 am pdt Thursday... Current radar imagery
shows a few isolated showers over the coastal waters with mainly
dry conditions over land. Satellite imagery and surface analysis
show a weak low and surface boundary offshore west of monterey
county. High res models continue to show the possibility of
isolated light showers, mainly south of the bay area, into the
early evening. However, any widespread rainfall is unlikely with
shower chances diminishing throughout the day. Temperatures across
the region this morning have been mainly in the 40s with areas in
the north bay in the upper 30s, about 5 to 10 degrees cooler than
this time yesterday. High temperatures this afternoon will be in
the upper 50s along the coast and over the sf peninsula with
inland locations reaching the mid 60s.

Once isolated showers clear out into this evening expect dry
conditions tonight before rain chances return ahead of an
approaching front. High res models show showers arriving early
tomorrow morning and spreading from northwest to southeast across
the region throughout the day with the main frontal boundary
arriving in the afternoon. The santa cruz mountains northward
still appear to see the highest rainfall totals with lesser
amounts in urban areas and for the southern portion of the region
(1.00"-1.50" coastal ranges and north bay, 0.50"-0.75" most urban
areas, and less than 0.25" elsewhere). Locally breezy conditions
are expected ahead of and in the wake of the frontal passage with
gusts around 35 to 40 mph. Expect post frontal showers to
continue into tomorrow night before showers diminish Saturday
morning. No updates needed to the forecast this morning, for
additional details see the previous discussion below.

Prev discussion As of 03:46 am pdt Thursday... A weak short-
wave disturbance approaching the coast this morning has resulted
rain showers off of the big sur coast which are beginning to push
inland. Elsewhere, mainly dry weather conditions prevail with
temperatures ranging from the upper 30s in the north bay valleys
to middle upper 40s elsewhere (near 50 around san francisco). As
the weak system pushes inland through the day, cannot rule out
isolated showers from the big sur coast up to the santa cruz
mountains. The short-range models do indicate the potential for
isolated showers as far north as the greater san francisco bay
area as well. However, widespread rainfall is unlikely with any
lingering showers likely to diminish through the evening. Daytime
temperatures are forecast to warm into the upper 50s near the
coast to middle 60s inland.

Dry weather conditions are then forecast tonight into early Friday
morning ahead of an approaching frontal boundary. This next system
will move from northwest to southeast across the region on Friday
with light to occasionally moderate rainfall. Most indications are
the santa cruz mountains northward through the north bay will see the
most with amounts from 0.50" to 0.75" in most urban areas (lesser
amounts in the east bay valleys and south bay). Meanwhile, 1.00" to
1.50" will be possible in the coastal ranges and north bay hills.

Rainfall amounts will tapper off across the central coast with most
locations picking up less than 0.25". Locally breezy conditions are
also expected ahead of and in wake of the frontal passage with gusts
to around 35 to 40 mph. Post frontal showers may linger into Friday
night before diminishing region-wide on Saturday. Saturday and
Sunday appear to be mainly dry in between weather systems with
daytime temperatures generally in the 60s on Saturday to potentially
upper 60s (inland) by Sunday.

Weather conditions next week continue to look unsettled with another
round of precipitation returning as early as Sunday night. However,
the forecast models don't agree on the specifics to timing, amounts
and location of heaviest precipitation at this time. With this said,
the ensembles point toward the potential for more widespread
rainfall through at least the first half of next week. The forecast
will be worth monitoring in the coming days.

Aviation As of 4:38 am pdt Thursday... For 12z tafs. Infrared
satellite imagery shows an upper level low spinning southeastward
toward the central coast this morning. There have been some echos
on radar overnight, but there returns have trended downward in
coverage over the past several hours. With the isolated showers
mainly confined from mry and points south,VFR conditions are
generally expected to prevail at the TAF sites through the day.

The exception to this would be sts and perhaps lvk where some
patching morning fog may bring reduced visibilities. Light winds
this morning are forecast to become onshore this afternoon. By the
end of the TAF period, the next storm system will be approaching
the region with winds expected to become southerly once again in
the 24-36 hour timeframe.

Vicinity of ksfo...VFR conditions are forecast to prevail through
the day. Winds will remain relatively light in the morning and
will become onshore around 10-15 kt this afternoon. High clouds
will increase through the period with winds becoming southerly by
the end of the 30 hour TAF as the next system approaches.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Isolated showers have been detected
within the vicinity of mry this morning as an upper level low
tracks southeasterly along toward the central coast. Other than
a stray shower or two over the next few hours, offshore winds
this morning will become onshore this afternoon for both mry and
sns.

Cwsu oakland forecast... Vaps this afternoon through the evening.

Confidence: med
yesterday's trough and low has moved east with a hang back low
southeast of monterey. The low layers remain moist over the area and
there is patchy low clouds in the bay... Mainly in the east bay. As
of now I do not foresee them expanding enough to interfere with
the approach.

Marine As of 03:46 am pdt Thursday... Rain shower chances will
continue through the early morning hours, mainly from pigeon point
and locations south. Weak high pressure will build off the
southern california coast through the day bringing light west to
northwest winds. Winds will turn southerly and increase on Friday
as a frontal system moves in. A moderate- period west swell will
continue through Thursday before a longer period west to northwest
swell arrives on Friday.
