209 pm pdt Wed oct 16 2019

Synopsis Light rain will be possible across portions of the
region this evening into early Thursday morning as a weak cold
front sweeps through northern and central california. Cooler,
breezy conditions develop in wake of the frontal passage by
Thursday afternoon and will continue into Saturday. A warming and
drying trend is then forecast late in the weekend and into early
next week.

Discussion As of 02:10 pm pdt Wednesday... Only minor
adjustments were made to the forecast this afternoon. High clouds
ahead of an upper trough and cold front continue to spread through
the region. Temperatures so far today have been cooler under the
extensive cloud cover and a cooler air mass beginning to advect
into the region. The cold front will begin to move into the north
bay this evening and push into the greater bay area late in the
evening, continuing through the remainder of the forecast area
overnight. Showers will accompany the cold front but rainfall will
be scattered and light. The cold front will also weaken as it
moves through the forecast area, so the highest precipitation
totals will be across northern sonoma county (up to 0.10) with a
hundredth or two elsewhere. Any rain which occurs create
temporary slick roads overnight, but otherwise impacts should be
minimal. Rainfall for most areas will end before sunrise Thursday,
with only a few isolated showers remaining in the hills of
monterey county Thursday morning.

Cooler temperatures will continue through Thursday and winds will
increase behind the cold front. The strongest winds will be felt
along the coast and in the hills with gusts up to 25-35 mph with
isolated gusts to 40 mph. Valley locations can expect to see
gusts 15-25 mph Thursday afternoon. Winds will decrease after
sunset, but breezy winds will develop once again on Friday.

Temperatures will remain cool as northwesterly flow continues to
bring in cool air behind the departing trough. Coastal areas will
see highs in the 60s while inland areas only warm into the low
70s.

Another weak system will move through the region on Friday night
and Saturday. This will bring a chance of showers to the north bay
on Saturday morning, with dry conditions elsewhere. Cool
temperatures will continue on Saturday.

A ridge of high pressure over the northern pacific will then
begin to amplify on Sunday and shift towards the west coast early
next week. A robust warming trend will develop as a result with
highs near the coast in the 70s to low 80s and inland temperatures
in the 80s early next week. Ensemble forecasts indicate this
pattern is likely to persist through much of the week as the ridge
remains centered just off of the west coast. Periods of offshore
flow will likely develop next week, but the details remain
uncertain at this time.

Aviation As of 10:40 am pdt Tuesday... High clouds continue to
stream over the area at around 15,000 to 20,000 ft agl. Patches of
low clouds remain around the monterey bay withVFR conditions
observed elsewhere. ExpectVFR conditions to prevail into this
evening before a cold front moving from NW to SE provides a slight
chance of showers along with lowering cigs. MVFR to ifr cigs
expected overnight and into tomorrow morning. Low confidence on
timing and height of cigs. Light winds this morning to turn
onshore this afternoon around 10-15 kt. Winds may briefly turn
southerly ahead of the front as it moves through overnight before
turning back out of the W nw.

Vicinity of ksfo... Low clouds have mainly cleared out of the
terminal with a small patch of stratus still over the smb.VFR
conditions to prevail into this evening before CIGS lower
overnight. Slight chance of showers overnight accompanying
lowering CIGS due to a passing cold front.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Low clouds remain over kmry and are
expected to be clearing out within the next hour or so. High
clouds will continue through today before CIGS lower this evening
and overnight ahead of a cold front. Ifr MVFR conditions expected
overnight with a slight chance of showers early tomorrow morning.

Marine As of 02:02 pm pdt Wednesday... Light northwesterly
winds will persist over the coastal waters this afternoon. Winds
will then briefly turn southerly from north to south late this
afternoon and tonight as a weak cold front moves through the
waters bringing some light rain. Northwest winds will return and
gradually increase behind the front tomorrow. Expect locally
stronger winds along the big sur coast through much of the
weekend. A large northwest swell will arrive tomorrow and build
into Friday. These swells will create hazardous seas over the
waters tomorrow and Friday.

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.
