229 pm pst Sun feb 17 2019

Short term Tonight through Wednesday night... Current
observations are showing shower activity largely along the
cascades and portions of klamath and siskiyou counties. These
showers are producing light snowfall accumulations, and will
generally decrease in coverage later this evening. Skies should
otherwise clear out this afternoon and evening, with few clouds
here and there. This has made for a relatively difficult minimum
temperature forecast, where areas which continue to see clouds
will remain somewhat warmer than those that are able to see the
clear night sky. Also imagine some of the west side valleys could
see some freezing fog. Have left it out of the rogue valley for
now as soundings show a little bit of low level dryness.

Have lowered temperatures a bit, especially across our colder
spots east of the cascades (sprague river, christmas valley etc.)
to the low single digits. It wouldn't surprise me if we saw
reports of negative temperatures tomorrow morning in those places.

Additionally, kept temperatures near freezing along the coast.

Have issued a freeze warning on the assumption that the coast will
clear out. If it doesn't outright freeze, expect heavy, widespread
frost.

This overall break in our active pattern will continue on Monday
and most of Tuesday providing another relatively benign, yet
colder than normal, couple of days. This break in the active
weather pattern, however, will be short- lived as the next system
will travel down the pacific northwest on Tuesday night and
Wednesday. Since temperatures will not have rebound toward normal,
this means we will have to deal with another round of low pass
snow, and possibly flirt with snow on the valley floors. Snow
levels will be around 1500 to 2000 feet depending on where you
live. Since precipitation on Tuesday night starts of showery,
thanks to relatively unstable conditions, snow impacts will
largely depend on if heavy showers briefly bring snow levels down
to the valley floors on Tuesday night Wednesday morning. Come 9-10
am on Wednesday, the snow impacts will should be limited to areas
above 2000 feet (largely the higher passes). That's not to say
that snow won't fall at the lower passes, it's more likely that
the snow will melt as it falls. Granted, if the timing of this
system does change and the majority of the snow falls at night (not
super likely as models have shown consistency), there could be
more snow impacts for the low passes.

As precipitation continues through Wednesday night, snow levels
will drop down to the valley floors yet again--this is when the
front will finally arrive across southern oregon and northern
california. At the same time, the passage of the front will also
largely shut off the showers. So whether or not the valleys
receive any snow will depend on whether or not the snow levels
lower before the showers end. Overall, could see a similar skiff
of snow in valleys like we saw this morning. -schaaf

Long term Thursday 12z until Monday 12z...

the start of the forecast period starts with a deep area of low
pressure moving through california. Showers will linger Thursday
morning as this low departs. However, most of the moisture will be
depleted into Thursday morning, so just look for some very light
showers.

High pressure will build Thursday evening and Friday morning. East
of the cascades, we'll see some cold temperatures with lows falling
into the single digits.

As for the next system, both models have a system sliding down from
the gulf of alaska with an established area of high pressure off the
coast of california. With the high pressure setting up farther
north, we would then see less rain Saturday and into Sunday. If it
sets up farther south, there is higher potential for a weak
atmospheric river event. Overall, there are still some major
differences in the models next weekend, but its safe to say we have
a good chance of seeing more precipitation next weekend.

Aviation For the 17 18z tafs... Isolated to scattered snow
showers with mountain obscuration continue across the area this
morning. Conditions may briefly lower to ifr in any of these snow
showers, but conditions will be MVFR or better outside the
showers. Showers will continue to drift through the area today,
but the trend is for showers to decrease through the day, and by
evening, they will likely have ended. Conditions will generally
trend towardsVFR this afternoon, but ifr conditions will return
late tonight to interior valleys west of the cascades as lower
ceilings form with reduced visibility. -wright keene

Marine Updated 200 pm pst Sunday 17 february 2019... Steep
northwest swell will gradually subside through tonight, dropping
below 10 feet in the northern waters by Monday morning. Then seas
lower below 10 feet south of CAPE blanco Monday evening. Winds
will be from the north at 15 to 20 kt through Monday. Seas will
subside further Monday night into Tuesday morning. Then another
front brings increasing northwest winds and seas Wednesday into
Thursday. Latest data suggests northwest winds will peak at 25 to
30 kt late Wednesday afternoon. Winds and seas subside Thursday
into Friday.
