455 am pst Tue nov 20 2018

Synopsis
Dry with near to above normal daytime temperatures today with
smoke in the valley due to the camp wildfire. Cooler and wetter
weather starts tomorrow and will continue through the holiday
weekend. Snow over the higher elevations of the sierra will make
travel difficult for the thanksgiving travel weekend.

Discussion
Satellite imagery this morning shows a pacific trough digging into
baja california which will help nudge the persistent west coast
ridge eastwards. Behind this ridge is another area of low pressure
which will slowly be advancing towards the region. Rain is
forecast to spread into the coastal range late tonight and into
tomorrow morning and eventually encompass all of norcal by
tomorrow afternoon and evening. With that being said, commuters
and holiday travels are urged to allow extra time for travel
since this is the first widespread rain of the season and roads
will be particularly slippery due to an accumulation of oil
through the summer and early fall.

In addition to our wet roads in the valley, those that need to
travel over the sierra tomorrow should be mindful of the snow
levels since they are forecast to fall to around 6000 feet in the
evening hours. Accumulating snow is forecast at these levels,
thus the winter storm watch remains in effect from tomorrow
afternoon through Friday morning.

Thanksgiving day we will see our first system exiting, with
another and more potent storm arriving in the afternoon and
evening. There may be a brief lull in the intensity of rain
during the day, but it will remain possible through the day with
some light snow continuing through the mountains. Come Thursday
afternoon and evening, southerly winds will be ramping up and
become quite breezy which will then last into the overnight hours.

Periods of moderate to heavy rain are expected, with the heaviest
expected Thursday night into early Friday for areas north of i80.

Snow impacts will be a problem for those needing to travel, thus
we extended the winter storm watch through Friday morning.

Conditions will gradually improve on Friday as the low exits the
region and snow levels start to rise.

Newly burned areas will likely see ash flow from moderate rain.

The major question is whether rain intensity could reach levels
sufficient to cause more hazardous debris flows as a cold front
moves inland. There is still quite a bit uncertainty, but there is enough
potential to keep the flash flood watch in effect for debris
flows at the mendocino complex, the carr, delta, hirz fires and
the camp fire. Flooding outside of the burn areas is not expected,
except for local ponding on roads with clogged drains. Kr ek
.Extended discussion (Saturday through Tuesday)
drier weather is expected by Saturday afternoon as the trough
shifts eastward into the great basin. Then, ridge of high
pressure is expected to build into ca, bringing dry conditions
into early next week. A weak system moves north of the forecast
area late Saturday into early Sunday, and might bring some light
precipitation mainly over the northern mountains. Model guidance
indicates the possibility of additional precipitation moving
across interior norcal by the middle of next week, but model
differences exist in terms of timing and precipitation amounts.

Forecast highs will be in the mid 50s to low 60s across the
central valley, and 40s to 50s over the mountains.

Aviation
Widespread MVFR with local ifr likely to continue in the central
valley as smoke from the camp fire persists; improving conditions
mainly after 03z-06z Wednesday. Otherwise,VFR conditions
elsewhere. Winds less than 10 knots at TAF sites. Precipitation
will be reaching the coastal range mainly after 09z-12z
Wednesday.
