329 pm pst Mon nov 19 2018

Synopsis
Dry with near to above normal daytime temperatures and cool
nights through Tuesday with smoke in the valley due to the camp
wildfire. Cooler and wetter weather is expected by midweek and
for the holiday weekend. Snow over the higher elevations of the
sierra for possible travel difficulties during thanksgiving travel
weekend.

Discussion
One more day of dry weather with hazy smoky conditions is expected
on Tuesday. The morning will be cool once again, with lows
dropping into the 30s across the valley and delta. Increasing
clouds are expected through the day, with slightly cooler high
temperatures than today.

A pacific trough will move into baja california by early Tuesday,
helping to shift the persistent west coast ridge eastward. A
pacific trough approaches Tuesday night, with rain spreading into
the coastal range late night and moving through the rest of the
area by Wednesday morning. Wet roads on the first widespread rain
of the season will be particularly slippery due to an accumulation
of oil through the summer and early fall. Commuters and holiday
traveler on Wednesday are urged to allow extra time.

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 issue a flash flood watch 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.

Snow levels will gradually be decreasing during through the
afternoon and will fall to around 6000 feet in the evening hours.

A winter storm watch is in effect from Wednesday afternoon through
early Thursday morning. For those traveling over the sierra passes,
accumulating snow is expected to be a problem starting at
elevations around 6000-6500 feet
thanksgiving day will see our first wet system exiting, with
another wet storm arriving in the afternoon and evening. There
may be a brief lull in intensity during the day, but rain remains
possible through the day with some light snow continuing through
the mountains. Periods of moderate to heavy rain are expected,
with the heaviest expected late night Thursday into early Friday
for areas north of i80. This will limit snow impacts over i80 and
highway 50 to some degrees.

Temperatures Wednesday and Thursday will not be as cool in the
morning hours, due to cloud cover limiting radiational cooling.

This means lows generally in the mid 40s for much of the valley
and foothills. Daytime highs will be cooler, though, remaining in
the 50s for those areas. Ek
.Extended discussion (Friday through Monday)
another system is forecast to move across northern california Friday
morning until Saturday early afternoon. The heaviest precipitation
still looks to impact the area Friday with amounts tapering off by
Saturday morning. A slight warming will raise snow levels to nearly
7000 feet Friday night, allowing mostly all of the precipitation to
fall as rain. Friday night into Saturday an additional half to two
and a half inches of rain may be seen, with the heaviest amounts in
the foothills and mountain areas. As always, post thanksgiving
holiday travelers should leave more time for driving and expect some
delays. There is still a concern for possible debris flow over
previously burned areas but there is low confidence for rain rates
at this time.

Another shortwave may move southeast across the central valley
Saturday into Sunday leaving a small chance for additional, light
rainfall over the mountains and foothills. Dry conditions are
expected for Monday.

High temperatures Friday through Monday remain just below
climatology, generally topping out in the mid to upper 50s in the
valley, and in the 40s at higher elevations.

Aviation
Widespread MVFR with local ifr likely to continue in the central
valley the next 24 hours as smoke from the camp fire persists.VFR
conditions elsewhere. Generally light winds at TAF sites. High
clouds are moving northeast across TAF sites this afternoon.

Sto watches warnings advisories
Flash flood watch from Wednesday afternoon through Friday
morning for central sacramento valley-clear lake southern lake
county-mountains southwestern shasta county to northern lake
county-northeast foothills sacramento valley-northern sacramento
valley-shasta lake area northern shasta county-western plumas
county lassen park.

Winter storm watch from Wednesday afternoon through late
Wednesday night for west slope northern sierra nevada-western
plumas county lassen park.
