area forecast discussion

815 pm pdt Sat mar 25 2017

Discussion Mostly dry conditions are being observed across the forecast
area this evening. We are in between weather systems, with high
clouds streaming out ahead of the next storm. A warm front will
arrive Sunday morning and spread precipitation across most of
northern california and southern oregon, followed by a cold front
Sunday evening into Monday morning. Snow levels should be just
high enough to not cause major impacts on the front end of the
system tomorrow, around 4500 to 5000 feet with road temperatures
warming to above freezing in most places before the heaviest
precipitation arrives. So, in short, expect brief snow impacts to
some passes around 5000 feet in the morning before road conditions
become wet later in the morning... With more sustained winter
weather impacts above 5000 feet. Indications are that the higher
impact winter weather will occur Sunday night into Monday morning
as the cooler air mass arrives. Finally, we'll have to monitor
highway 97 near chemult where some snow on roadways is possible. A
winter weather advisory at wswmfr has been issued for these
expected late season travel impacts.

Wind impacts do not look very impressive with the upcoming front
with 10000 foot winds peaking at 30-40 kt and local guidance
suggesting sub-advisory wind gusts in the most wind-prone areas
like the east side and shasta valley.

Please see the previous winter weather discussion for details on
the upcoming weather system and another storm mid to late week.

Aviation 26/00z TAF cycle...VFR will continue tonight with
occasional MVFR cigs. Mountains and terrain will be partly obscured.

A cold front will sweep across the coast early Sunday morning and
weaken as it spreads inland through the day. Ahead of this front, a
stronger SW winds aloft could lead to llws at the three west side
tafs as early as midnight local time. The front will also bring
increased coverage of MVFR for areas west of the cascades with local
ifr over the coastal range. Precipitation will be mainly light to
moderate with locally heavy amounts in curry county from late
morning into the afternoon. The freezing level will be around 5000
to 5500 feet msl. /fb

Marine Updated 200 pm pdt Saturday 25 march 2017... Seas are
hovering around 10 feet this afternoon and are expected to remain
around 10 feet overnight. As a result we will maintain the small
craft advisory for seas into tonight and expand the hazard coverage
closer to shore. Winds for the most part are not expected to be a
concern through this evening; however, a front will move towards the
waters later tonight. South winds will ramp up fairly quickly to
small craft advisory after midnight, then to gales by Sunday
morning. Steep seas are also expected. The models are in pretty good
agreement pushing the front onshore Sunday evening at which point
winds will decrease and become southwest. However seas will remain
steep through Sunday evening. Seas will decrease Sunday night into
early Monday morning, then a combination of a longer period and
shorter period west swell is due to move in Monday afternoon
resulting in combined seas between 10-13 feet. /fb

Prev discussion /issued 245 pm pdt Sat mar 25 2017/
discussion... 25/12z nam/gfs/ec in.

The northern hemispheric projection shows a wave number of four
around the globe... Which argues for a slow progressive pattern.

That is indeed what we will get over the next several days.

Overall the pattern looks quite spring like... With weaker storms
driven by low amplitude upper level troughs. The primary storm
track will remain to the north of the area... But there will be
some action down here.

A weak upper level trough is now moving through the area...

bringing isolated to scattered shower activity. Amounts are quite
light and the bulk of it is falling from the cascades west.

The showers will diminish through this evening as a flat ridge
builds over the area. The break will be short-lived, as the next
system will move in tonight.

Sunday through Monday morning look to be fairly wet as an upper
level trough approaches the coast and sends several short waves
out ahead of it. The first of these short waves will support a
surface front which will move onshore early Sunday morning. This
will bring precipitation to all of the west side and most of the
east side Sunday... Along with gusty winds over the ridges... In
the shasta valley... And east of the cascades. At this time it
appears that winds will remain below advisory criteria. With the
cold core aloft... Isolated thunderstorms are also possible
Sunday... Mostly along the coast and over the coastal waters. There
may be a few on the east side as well. Snow levels will rise to
4500-6000 feet Sunday... Then fall to around 3500-4500 feet Sunday
night.

Subsequent short waves will support plenty of shower activity
Sunday night into Monday. The last of the short waves and the
long wave trough will move through the area Monday. Showers will
diminish in the wake of the trough. Snow levels will be 3500-4000
feet or so.

After that, there will be a longer break in the action as a long
wave ridge moves toward the west coast. This will bring dry and
warmer weather to the area. The ridge axis will break to the east
of the area Tuesday night. After that, there are significant model
differences regarding the timing and strength of the next front.

In any case, that system looks to be moderate at best.

Long term... Wednesday through Saturday.

Model agreement diminishes on Wednesday with the 12z ECMWF colder,
wetter, and faster with the arrival of a warm front than the 12z gfs
or GFS ensemble mean. Based upon the previous run of data and recent
model performance, the forecast still leans toward the ECMWF with
the probability of precipitation south and east of the umpqua divide
only nudged a bit lower. For much of southwest oregon, rain is still
likely on Wednesday.

The trailing cold front is likely to arrive Wednesday evening or
late Wednesday night and continue across our area through Thursday
with a higher probability of widespread rain and snow. The model
trend has been to send the upper trough on more of a southeast
rather than east trajectory. As a result, temperatures and snow
levels for Wednesday night into Thursday have been adjusted
lower... Expected to be around 7000 feet ahead of the front then down
to 4000 feet as precipitation tapers to scattered/numerous light
showers/snow showers during Thursday afternoon and evening.

A cold northerly flow with diminishing cloud cover is expected
Thursday night into Friday morning with low temperatures likely to
be a couple to several degrees below normal for most of our area.

A high pressure ridge is likely to bring a warming and drying trend
Friday into Saturday with the storm track pushed northward into
canada. -dw
