Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Light to moderate winds will once again prevail over the coastal waters. Winds will be locally stronger north of point reyes. Winds along the coast will turn southerly on Friday as low pressure develops off the southern california coast. Monsoonal moisture from the se will leave a very slight chance of Thunderstorms Thursday and Friday. A southerly swell will arrive Saturday night and continue through early next week.

Synopsis Seasonably warm temperatures will persist region-wide
through the forecast period with marine air keeping conditions
cooler at the coast. Monsoon moisture will spread over the region
and provide a slight chance of high-based convection today and
Friday along with an increase in cloud cover. Drier conditions
then return by the weekend.

Discussion As of 08:57 am pdt Thursday... Update this morning to
diminish chances of high-based convection over the region for
today as the deeper moisture appears to be a bit further south
than previously though. Vandenberg afb 12z upper air sounding
showed a pwat value of 1.54" with MUCAPE of 716 j kg with showers
and thunderstorms showing up earlier this morning south of
our region. Cannot rule out a rouge high-based shower or
thunderstorm over the far southern coastal waters or monterey
county later this afternoon, yet do believe convection will be
limited at best over these areas and remain to our south. With
this said, have increased inland temperatures a bit as it appears
high level clouds will not be as thick over our region today.

The latest 12z forecast guidance does show increased moisture and
instability over portions of the region from late tonight into
Friday morning. Thus, will leave chances of high-based convection
in the forecast for this timeframe at this time. For additional
information, please see the forecast discussion below and look for
our full afternoon update due out around 2 pm pdt.

Prev discussion As of 2:25 am pdt Thursday... The marine layer
depth remains around 1500 feet deep, per the fort ord profiler,
and low clouds have once again moved into inland valleys. Areas of
coastal fog and light drizzle are expected by morning. High
pressure aloft will result in another warm day with highs in the
60s to mid 70s at the coast, to the 80s and 90s inland.

More interesting is the influx of monsoonal moisture into the
southern third of our district from the desert southwest, as can
be seen on satellite water vapor imagery. Local radars are
showing fast-moving widely-scattered showers moving from east to
west across northern san luis obispo county, and one cell with a
50 dbz core now quickly moving across extreme southern monterey
county. No nearby lightning detected as of now, but increased
chances of this are expected later today as the moisture continues
to filter northward into more of our cwa. The possibility for
high-based thunderstorm activity will persist into Friday.

Drier southwest flow aloft is then forecast to develop by the
weekend which should end chances for high-based convection over
the area. High pressure will also continue to keep high
temperatures at or above seasonal normals, especially across
inland areas heading into early next week. Marine air is expected
to keep near-coastal areas cooler.

Aviation As of 5:02 am pdt Thursday... Weather conditions are
similarly conducive to ifr lifr on the coast and around the bays
this morning as compared to yesterday morning. It'sVFR inland.

Mid to high level clouds are moving in from the southeast; a high
cloud based shower with echo tops briefly to 30-32 thousand feet
passed westward over southern monterey county earlier this morning
otherwise it's been quiet weatherwise. Inspection of (limitedly
available) weather obs in the vicinity of the shower over southern
monterey county had not shown any increase in surface based winds
of any kind, and no lightning with this cell. Ingredients for
isolated t-storm development appears a bit disorganized today,
tonight and Friday; convective inhibition present offsetting mid
level convective potential (where best potential is) as well as
for surface based convection. 12z tafs are a mix of ifr lifr due
to stratus and fog, and mid to high level cloud cover this morning
with general trend toVFR this afternoon.

Vicinity of ksfo... 5 min observations indicating MVFR broken cig;
12z TAF forecasts ifr cig until 16z. Light W wind increasing and
becoming w-nw and gusty to 20-23 knots this afternoon. Slightly
higher than moderate confidenceVFR returns by 16z this morning.

Fairly good chancesVFR holds through the afternoon and evening.

Sfo bridge approach... San mateo bridge MVFR cig, ksql ifr cig.

Clearing may not be as quick as it was yesterday morning, add to
this scattered mid to high level clouds entering the picture from
the south which could hold low CIGS in place a bit longer this
morning. Low confidence forecast.

Monterey bay terminals... Ifr lifr this morning, low clouds
clearing beginning 17z-20z. Mid and high clouds this afternoon and
evening,VFR. Low confidence ifr forecast mid to late evening.

Marine As of 08:57 am pdt Thursday... Light to moderate winds
will once again prevail over the coastal waters. Winds will be
locally stronger north of point reyes. Winds along the coast will
turn southerly on Friday as low pressure develops off the southern
california coast. Monsoonal moisture from the SE will leave a
very slight chance of thunderstorms Thursday and Friday. A
southerly swell will arrive Saturday night and continue through
early next week.
