Short term There will be a day of quiet weather before the next
storm impacts our forecast area. For tonight stable atmosphere
returns with low clouds and fog in the valleys. The next front
however will approach the coast a warm front. This front could
provide enough lift for occasional light rain at the curry county
coast and the higher terrain of western siskiyou county. Rain is
expected to move into the coastal waters Wednesday morning but
precipitation should hold off from reaching the coast until
Wednesday afternoon. South to north pressure gradients increase
significantly in the afternoon, enough for wind advisory level in
the shasta valley and part of klamath and lake counties.

Confidence is high on measurable rain at the coast and the umpqua
basin for Wednesday afternoon, but low for the rogue valley.

Increasing southeast winds Wednesday afternoon and early evening
will lead to downsloping condition for the rogue valley and rain
could hold off until late Wednesday evening. Also with southeast
winds into jackson county, we are leaning toward a warm day and
medford- ashland could see high temperature around or into the
lower 60s Thursday.

The cold front is expected to move slowly into our area. Snow
levels on Thursday lower to around 6000 feet from cascades west
and around 7000 feet east, then 3500-4000 feet Thursday night and
Friday and 2500 feet Friday night. Between 8-12 inches of snow is
expected at crater lake and mount ashland in the two day stretch
from Thursday to Friday night. Fb

Long term Saturday through Tuesday.

The general consensus is the pattern will remain fairly active
during this time period. There will be some breaks in the action,
but not for an extended period of time. There are difference in
the timing of the next front on Saturday. Particularly with the
ecmwf which is about 12 hours slower with the arrival of the front
and colder air. The GFS and canadian are in better agreement. The
slower arrival of the front shown by the ECMWF is from the most
recent run. The previous run was similar to the GFS (still with
some minor differences). The forecast for Saturday will lean
towards the GFS canadian solution. With that said, winds will be
the main impact Saturday afternoon through Saturday night. Winds
have a chance to reach warning criteria at the coast late Saturday
afternoon and evening. High end advisory levels are likely in the
shasta valley and portions of the eastside Saturday night into
Sunday morning with some areas like weed and summer lake reaching
high wind criteria. Precipitation on Saturday should be on the
light side overall. Saturday night into Sunday will be highly
dependent on the timing of the front. Even then, it looks like the
highest precip amounts will be in the usual areas. The coast and
coastal mountains and the cascades. Snowfall accumulations will
also be dependent on the timing of the front. Thus, confidence is
low with rainfall and snowfall accumulations and could change from
what's currently in the forecast, so watch for updates on this.

Depending on how things shake out this weekend we could catch a
relative break in the action Monday. Moist northwest flow on Monday
will result in showers mainly confined to the coast. Tuesday will be
a wild card. The ECMWF shows a dry solution while the GFS and
canadian show moisture being directed into northern california
towards modoc and siskiyou county. -petrucelli

Aviation 16 18z TAF cycle...VFR conditions will prevail into this
evening, then areas of ifr CIGS vsbys will develop in the west side
valleys tonight, persisting into Wednesday morning. Areas of MVFR
cigs will develop at the coast during the day Wednesday and winds
will increase as well as a front approaches the area.

Marine Updated 230 pm pst Tuesday 16 jan 2018... Conditions
will be hazardous to small craft through tonight due to steep
westerly swell and increasing south winds. A strong front will move
through the coastal waters Wednesday with strong south gales to most
of the area and storm force winds and or gusts beyond 15 nm of the
coast north of CAPE blanco. The front will move onshore Wednesday
evening, with a very high and dangerous westerly swell to follow
late Wednesday night into Thursday. The latest model runs indicate
that the swell will peak at around 27 feet early Thursday. A high
surf warning is in effect. Bar conditions will be dangerous with
extremely rough surf. Seas will remain elevated with weaker systems
moving through Thursday night into Friday. Another strong front will
move through Saturday night into Sunday.
