Discussion Some light precipitation continues near the
cascades and over the east side early this morning as energy aloft
rotates around the closed low that moved through northern
california and into nevada last night. Snow levels there are
generally in the 5000-6000 foot range, though we have seen some
wet snow mixing in on some of the web cams at highway 395 at
alkali lake and at the highway 97 and 138 interchange. So, snow
levels may be locally around 4500 feet early this morning. This
precipitation should tend to fall apart by this afternoon as that
energy exits to the east.

Areas west of the cascades will be between systems today, so most
locations will squeeze out a dry day. Fog low clouds will shroud
some areas for a few hours this morning. Rain chances will
increase along the coast again mid-late this afternoon as yet
another potent disturbance arrives on a strong westerly jet.

Breezy conditions will develop again this afternoon. This system
will move through the area tonight into Tuesday with more showers.

Models are showing some instability over the coastal waters
tonight, and then over inland areas on Tuesday, so we have
included a slight chance of thunderstorms. Some snow will impact
roadways above 5500 feet with a winter weather advisory in place
from midnight tonight until 8 am Tuesday. Please see wswmfr for
specific details, but the main takeaway is if you are planning to
travel through the mountains tonight into Tuesday morning, please
be prepared for wintry conditions. Even though snow could continue
Tuesday afternoon, expect most will melt on roadways due to the
strong may Sun and higher road surface temperatures. Overall, it
will be quite cool for late may with high temperatures averaging
10-15 degrees below normal.

Showers diminish, but don't go away completely Tuesday night into
Wednesday morning as the upper trough moves into the great basin.

Back side energy will probably re-energize showers Wednesday
afternoon evening, especially from the cascades eastward. Expect a
little boost to afternoon temperatures, with highs of 65-70
degrees for west side valleys and mostly 55-60 east of the
cascades.

On Thursday Friday, we'll likely see temperatures rebound closer
to where they should be for this time of year. The forecast area
will be directly between a ridge aloft amplifying out near 140w
and the long wave trough that extends from the great basin to the
intermountain west. Expect northerly flow to continue, but with
some modification of the air mass aloft. Shower chances should be
lower, but still can't rule them out here or there, especially
near the cascades and from winter rim to the warners.

Meanwhile, with the ridge amplifying along 140w, another
disturbance will drop southward along the bc coast. This system
will develop into a trough closed low over the pacnw, and then
move southward into california this weekend. Since there are
differences with respect to the details, we have utilized a
multi-model blend of solutions (nbm) for the extended forecast.

But, overall, this should keep us in a showery pattern, with some
potential for thunderstorms, especially along and east of the
cascades. -spilde

Aviation For the 20 12z tafs... Ifr low clouds and fog will
thicken at the coast and in southwest oregon valleys until sunrise,
then dissipate rapidly by around 16z. Otherwise,VFR conditions will
prevail through this afternoon. An incoming front will bring
widespread showers beginning this afternoon over the coastal waters
and spreading inland this evening with the higher terrain becoming
obscured. Also, areas of MVFR CIGS vsbys are likely to develop west
of the cascades.

Marine Updated 230 am pdt Monday 20 may 2019... A cold front
will move through the waters today into this evening. South winds
will increase to advisory strength by noon, and gusts may briefly
reach gale force as winds peak early this evening. The associated
low will follow tonight into Tuesday with a building west swell.

This swell is expected to peak on Tuesday morning at 14 to 16 feet
at 14 seconds.

Offshore high pressure will rebuild Wednesday and persist through
the remainder of the week. This will bring moderate to strong north
winds and steep to very steep shorter period seas with a dominant
mix of wind wave and fresh swell. Winds will be strongest and seas
will be highest beyond 8 nm from shore, especially south of gold
beach.
