Short term A cold front is making its way through the forecast
area this afternoon, bringing areas of precipitation and breezy
winds. So far, the big winners on precipitation amounts are along
the coast with between 0.50" to 0.75" reported along the curry
coast and coastal mountains. Elsewhere, amounts range from 0.25"
to 0.50" roughly west of i-5 with generally less than tenth of an
inch east of i-5. Some light precipitation will continue through
the remainder of the afternoon, but guidance indicates that the
heaviest precipitation has already fallen today. Winds are breezy
across the area as well, especially in the shasta valley where
winds have gusted to 45 mph in the past hour. A wind advisory
remains in effect for this until late this afternoon, and details
can be found at npwmfr.

Winds diminish this evening, and precipitation will become
showery west of the cascades overnight. East of the cascades,
shortwave energy moves through the area as the upper level trough
swings inland. This will generate another round of precipitation
across the east side as snow levels lower to around 4000 feet
tonight. Expect a brief period of snow accumulation late tonight
into Saturday morning of around 1 to 3 inches with locally higher
amounts for the warners, including cedar pass, of 3 to 5 inches.

While these amounts aren't enough to warrant any headlines, it has
been over a week since accumulating snow occurred east of the
cascades, so if you're traveling Saturday morning be prepared for
possible wintry conditions.

Meanwhile, as the trough swings inland late tonight into
Saturday, temperatures aloft will cool significantly, creating an
unstable air mass. Have maintained the thunderstorm mention in
the forecast for areas west of the cascades through Saturday
afternoon. Small hail will be possible with showers thunderstorms,
especially in the afternoon as daytime heating contributes to
instability.

Showers should taper off after sunset Saturday as the trough
moves to the east. A brief period of ridging will build into the
area Saturday night, leading to clearing skies and near-freezing
temperatures for many valleys west of the cascades. Areas of frost
will be possible Sunday morning, so those with agricultural
interests should take any necessary precautions to protect
vegetation.

The next system arrives Monday, and, while similar to today, this
one will be a bit more impactful than the system moving through
today. Winds will be breezy to gusty in the usual places, and the
trajectory of the system favors the heaviest precipitation along
the curry coast, western siskiyou county and south central
siskiyou county. The trajectory also favors high precipitation
rates around the black butte mt. Shasta area. Have maintained snow
levels of around 3500 to 4000 feet in this area, and this would
indicate a brief period of potential advisory level snow amounts
Monday morning. For the remainder of the area, this system will be
colder than today's, with snow levels hovering around 4000 feet.

We'll be keeping an eye for any additional potential winter
weather impacts. Precipitation will taper off Monday evening, and
we'll be in a relative break as we head into the extended. Br-y

Long term Tuesday through Friday... An active pattern continues
with south to southwest flow aloft on Tuesday and a low pressure
system moving into the area late Tuesday through Wednesday. During
the day on Tuesday, expect showers to increase, especially across
southern and western portions of the area as a frontal system
approaches from the west. This front will spread light to moderate
precipitation across the CWA Tuesday evening through Wednesday
morning. Heaviest precipitation is expected across curry, southern
josephine and western and south central siskiyou counties. Snow
levels are expected around 3500 to 4500 feet during this period.

Current models support light to moderate accumulating snow possible
on higher passes Tuesday evening through Wednesday morning.

The closed low will push into the oregon coast on Wednesday with
widespread showers expected over the area. Given the cold low
nearing the coast on Wednesday, may also see enough instability and
upper level dynamics for thunderstorms, especially over the marine
waters and into the coast. However the track of the low may be just
north of the cwa, so will continue to monitor this potential. Breezy
to gusty south winds are expected over the area on Wednesday, with
strong winds possible in the shasta valley and gusty winds east of
the cascades. Then the low will move inland and open up into an
upper trough on Thursday. This will result in continued showers.

Snow levels are expected to be around 3500 to 4500 feet Wednesday
and Thursday but may lower to 3000 feet at times, Wednesday night
and Thursday morning. On Friday, the upper trough may begin to shift
eastward. However, depending on how quickly this trough shifts out
of the area, lingering showers are possible. -cc

Aviation For the 22 18z tafs... A cold front moving through today
will bring valley rain and mountain snow above 4000 to 5000 ft msl
elevations today, followed by showers this evening through tonight.

MVFR conditions are likely along the coast and coastal mountains
through this evening. Conditions will gradually improve overnight.

Vfr and scattered MVFR conditions are likely farther inland and east
of the cascades the rest of today and overnight. Areas of terrain
obscuration can also be expected. Conditions east of the cascades
may become mostly MVFR after 22z with plenty of mountain tops
obscured. These conditions will continue through 18z Saturday.

Marine Updated 200 pm pdt Friday, 22 march 2019...

a cold front will move onshore this evening which will
allow gale gusts to decrease below gale force values.

Winds will shift to the west and align with the primary swell and
allow chaotic seas to end overnight. However, a large west swell
will keep seas over 10 feet through Sunday morning. Hence the small
craft advisory for hazardous seas. This will also result in
hazardous bar conditions and higher than average surf before
diminishing Sunday morning.

After a brief break in the action Sunday, another robust frontal
system is expected to arrive Sunday night into Monday morning. The
latest model solutions suggest it looks similar to the front that
moved through today so have trended the winds higher and forecasted
another bump in wind waves. This system could warrant another gale
warning but have left that out for now. Conditions should improve by
Tuesday, but long-term guidance suggests unsettled weather will
continue into next week, although exact details are uncertain at
this time. -sargeant
