412 am pst Tue dec 18 2018

Synopsis
Light rain north of marysville today and tonight. Dry Wednesday
then light rain spreading across the region late Thursday and
Friday. A period of heavier precipitation early next week.

Discussion
Dry over the CWA this morning under high pressure ridging. Some
morning fog has formed from about sacramento southward, but clouds
spilling over the ridge ahead of the next weak frontal band
precluding much fog development farther north. Some light showers
are already showing up over the north coast with light
precipitation expected to spread over the northern CWA later this
morning. Building upper ridge will bring clearing by Wednesday
morning so patchy morning valley fog may pop up again from about
sacramento southward. Otherwise, fair skies are expected Wednesday
afternoon with daytime highs climbing to around 10 degrees above
normal. Another fair night Wednesday will bring more patchy valley
fog early Thursday. Another pacific frontal band pushes through
late Thursday and Friday. Precipitation amounts are expected to be
light again with this system but snow levels will be below pass
levels so minor mountain travel impacts are likely.

.Extended discussion (Saturday through Tuesday)
an active pacific storm track should keep additional chances for
precipitation into the weekend as well as early next week.

Beginning Saturday, the start of the day is forecast to remain dry
ahead of the next shortwave trough nearing the northern
california coast by the evening. Model guidance continue to be at
odds with one another as the 00z ECMWF favors a much wetter
scenario across the region. This would mainly impact the second
half of the weekend if this were to verify. On the contrary, the
06z and 00z GFS runs support a storm track farther north.

Unsettled conditions can be expected but specific impacts still
remain nebulous given model differences at hand.

Looking into next week, christmas eve could prove to be quite wet
across the region. The mentioned runs of the GFS and ECMWF each
show a much more impressive trough sweeping through northern
california by Monday. However, ensemble forecast solutions show a
great deal of uncertainty with the timing and strength of this
system. Stay tuned to future updates as this feature becomes
better resolved. Given the current guidance available, it could be
a very cold system which would lower snow levels over the sierra
and southern cascade ranges. Some lingering showers could extend
into christmas morning while a slightly cooler air mass enters the
picture. Bro

Aviation
Local ifr lifr visibilities and ceilings possible from krbl-kmod
through about 18-20z Tuesday. Chance of light rain across the
northern mountains and N sac valley after 12-18z Tuesday, with
local MVFR ifr conditions in rain showers. Decreasing
precipitation expected after 12z Wednesday. Light winds at taf
sites.

Sto watches warnings advisories
None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
