Area Forecast Discussion
National Weather Service Medford OR
1112 PM PDT Mon Apr 10 2017

The Aviation section has been updated...

.DISCUSSION...
No updates are needed tonight as the forecast is well on track.

In addition to the information in the previous discussion, it
does appear that the mountains above 4000 feet will get another
round of significant snowfall Wednesday evening into Thursday.
There still is a fair amount of model spread in terms of amounts,
but areas above 5000 feet should see at least another 4 inches.
The NAM12 and ECMWF indicate 10 inches or more of new snow could
fall above 5kft in the Mount Shasta area, but other guidance
indicates lesser amounts. BTL

&&

.AVIATION...11/06Z TAF CYCLE...
VFR conditions will prevail overnight through Tuesday morning as mid
level clouds increase under an overcast high cloud deck. On Tuesday
terrain will become partially obscured as rainfall begins during the
morning some areas of MVFR CIG/VIS could develop, especially along
and near the coast and coastal ranges. Tuesday evening low pressure
is expected to move up the coast turning winds to the south over the
coastal waters and resulting a low level jet stream along and near
the coast. Significant low level turbulence and wind shear is
expected along and near the coast, to include in the North Bend area
in the 03Z-09Z time frame Tuesday evening. MVFR ceilings are also
expected along and near the coast Tuesday evening. BTL

&&

.MARINE...Updated 845 PM PDT Monday, 10 April 2017...Winds will
remain fairly light and variable and seas will gradually subside
through Tuesday morning as weak high pressure moves across the
waters. However, low pressure is already forming near 35N/140W,
and this low will strengthen and then turn north and move along
the PacNW coast Tuesday night into Wednesday. A warm front
associated with this low will cause rain to begin Tuesday morning
and persist through the day under a general east wind. Models are
in decent agreement today, and show similar timing, track, and
strength of the low, so confidence is growing that this storm will
bring gale force winds and very heavy seas to our area. That
said, small deviations in track and strength will have a large
impact on conditions, so confidence is not high enough yet to
upgrade the gale watch to a warning. However, the gale watch will
be expanded a little to cover potential changes in these details.
Mariners should assume the potential for gale force winds over
most of the waters between Tuesday evening and Wednesday morning
and prepare accordingly.

The weather will likely remain unsettled through Friday, followed
by a period of quieter conditions Saturday and Sunday. BTL/Wright

&&

.PREV DISCUSSION... /Issued 256 PM PDT Mon Apr 10 2017/

SHORT TERM...Isolated to scattered light showers are continuing
western portions of the area today, mainly over the coastal
mountains and into Douglas County. These showers will diminish
this evening. There will be a brief break in the active weather
tonight followed by a couple low pressure system moving into the
area late Tuesday through Wednesday night. These systems will
bring another round of gusty and potentially strong winds and
precipitation.

The first low pressure system will approach the Northern
California coast on Tuesday then will move northward along the
Southern Oregon coast Tuesday evening and night. As this low moves
along the coast, models show that it will deepen to around 996 to
1000 mb. The close approach to the coast, will allow a 7 to 8 mb
pressure gradient to develop along the coast from Arcata to North
Bend and inland from Medford to Redding. As a result, gusty south
winds are expected to develop over the area Tuesday evening
through early Wednesday morning with strongest winds expected over
the mountains, in the Shasta Valley and in the Summer Lake area.
Winds in these areas may gusts to around 60 mph. A high wind
watch has been issued for the Shasta and Summer Lake areas as well
as higher terrain in Lake and Modoc counties. Please see the
NPWMFR for details. Along the coast, winds are likely to gust to
around 45 to 50 mph with this low passage Tuesday night. Coastal
headlands and Cape Blanco may see stronger wind gusts to 60 mph.
These winds are expected to lower Wednesday morning as the low
shift northward. However winds will remain gusty across the area
Wednesday into Wednesday night as a front moves inland.

Snow levels will rise during the day Tuesday and Tuesday night to
around 5000 to 6000 feet as precipitation spreads inland.
Precipitation will be most widespread and continuous along the
coast, in the Mount Shasta area and into portions of the west
side, including the Southern Oregon Cascades, the Umpqua Valley
and Joesphine county. Overall, expect light to moderate
precipitation with locally heavy rain in Curry County.

This low will shift northward on Wednesday and another weaker low
approaches from the west and bring a cold front inland Wednesday
evening and night. As the front moves into the coast Wednesday
afternoon and inland Wednesday evening and night, expect
precipitation to increase across the area. Snow levels will lower
with the frontal passage Wednesday night down to around 4000 feet.
Models show the potential for significant snow accumulations over
the higher mountain passes in the Cascades. Also moderate to
heavy snow is possible in the Mount Shasta area. Around 5 to 10
inches of snow is forecast Wednesday night in the Southern Oregon
Cascades, mainly above 4500 feet. Lighter snow of 2 to 4 inches is
possible at Siskiyou Summit. In the Mount Shasta area, over 1
foot of snow is possible Wednesday evening and night above 5000
feet elevation with 3 to 7 inches possible between 4000 and 5000
feet elevation. There remains some uncertainty in how quickly snow
levels will lower Wednesday evening and night. This will factor
into how much snow may fall over area passes.

LONG TERM...The operational models are in fairly good
agreement through the forecast period. It will remain fairly active
with the only break in the action next Saturday into at least Sunday
morning. Not only will the pattern be active, but each storm is
expected to bring a cool air mass overhead, so we could be looking
at accumulating snow over the higher passes (Diamond Lake, Crater
Lake and possibly Lake of the Woods) and possibly in the vicinity of
Mount Shasta City.Snow could occur near and at Siksyou summit, but
with a strong April sun and warmer road temperatures, they should
remain wet most of the time during the day. However could not rule
out some road snow if heavier showers are in the area during the
night. This would be the case for Thursday night and Sunday night.
Keep in mind it's still a ways out there and details could change
from one day to the next, so stay tuned for the latest updates.
Right now it looks like the first half of next weekend will be dry
and milder. The models suggest the active pattern will continue into
the start of next week with a mean trough remaining over the area
and temperatures slightly below normal. -Petrucelli
