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.

Synopsis Dry conditions will return by Saturday. A warming
trend is forecast through the memorial day weekend as high
pressure builds over california. Cooler weather is then expected
to return by the middle of next week as another upper trough
approaches the coast.

Discussion As of 9:05 pm pdt Friday... Latest satellite and 00z
nam initialization indicate the upper low that brought scattered
light showers to our region last night and today is currently
centered over central california, and is drifting slowly to the
southeast. Radar data indicate that isolated showers ended around
sunset. However, the latest hrrr and NAM forecast isolated light
precipitation overnight. Will therefore leave slight shower
chances in the forecast overnight, but most areas will almost
certainly remain dry.

Dry weather is expected in all areas by Saturday morning as the
upper low moves well to our southeast. Moisture wrapping around
the departing upper low may keep some clouds over our area into
the morning hours, but expect mostly sunny skies by afternoon.

Temperatures are forecast to be slightly warmer on Saturday, but
still cooler than normal.

A robust warming trend is then forecast for Sunday and memorial
day as an upper ridge over the eastern pacific builds eastward
over california. 850 mb temperatures are forecast to warm from
about 5 deg c at the present time up to nearly 20 deg c by
Monday. In addition, onshore flow will gradually weaken through
the holiday weekend. Temperatures will warm back to around normal
on Sunday and then several degrees above normal on Monday. Some
of the warmest inland areas are forecast to see high temperatures
in the low to mid 90s by memorial day. Based on the boundary
layer rh forecast from the latest WRF model, we will likely see
areas of low clouds in coastal areas through Sunday, but enough
drying is expected in the boundary layer by Monday for more
widespread coastal clearing.

The models agree that an upper trough will approach from the
northwest on Tuesday. This will likely trigger an increase in
onshore flow and result in cooling at the coast and in the
coastal valleys. However, inland valleys will probably remain warm
into Tuesday. Widespread cooling is then expected by Wednesday of
next week as the trough deepens along the west coast. No
precipitation is expected through next week except for perhaps
night and morning coastal drizzle around midweek.

Aviation As of 4:42 pm pdt Friday... For 00z tafs. Kmux doppler
radar continues to show a few showers across the region therefore
have maintained vcsh in the tafs this afternoon. The chance of
showers will continue to taper. Confidence is low with respect to
cigs as the upper low moves directly over the forecast area this
evening. Anticipate a mixed bag of clouds through tonight with
cigs between 2000 to 5000 ft. Light onshore flow is expected
overnight into Saturday.

Vicinity of ksfo... CIGS remain around 2000 ft occasionally
lifting to 3000 ft. Borderline MVFRVFR conditions will continue
through tonight with broken CIGS temporarily scattering at times
late this afternoon early evening. Moderate southwest winds will
veer increasingly to west this evening. Vcsh due to occasional
weak showers through 04-05z Saturday.

Sfo bridge approach... Similar to ksfo.

Monterey bay terminals... Borderline MVFRVFR CIGS expected to
return around 03z this evening. Moderate winds will ease this
evening. Vcsh due to occasional weak showers through 03z
Saturday.

Marine As of 2:12 pm pdt Friday... Light winds will continue
this afternoon across the waters before increasing and becoming
northwesterly this evening. Winds will remain gusty through the
weekend and into the start of next week. Blustery winds early next
week will generate steep wind waves creating hazardous seas. A
mixed northwest and southwest swell will continue through the
forecast period.
