area forecast discussion
national weather service medford or
846 pm pst Tue jan 23 2018

Discussion No updates planned for this evening. The frontal
system is now about 150 miles west of CAPE blanco, and it has
started to slow down as it approaches the coast. Latest guidance
show it taking its sweet time from here on out, and the earliest
any guidance has it arriving at the coast is around mid-morning
tomorrow. Models also indicate a secondary front and wind surge
arriving late morning or early afternoon, and this is really what
forces the whole mess inland. Until then, it will remain windy
over the waters, coast, shasta valley, and portions of the east
side. This slowing many delay the onset of precipitation inland,
but not to enough of a degree to be worth meddling with the
forecast. All current headlines seem to be on track and remain in
effect. -wright

Aviation 24 00z TAF cycle... A cold front moving inland this
evening will bring rain, widespread MVFR ceilings and mountain
obscuration to the area. South winds will also be gusty at the
coast and east of the cascades. Low level wind shear will be a
concern along the coast and for west side terminals until around
10z Wednesday. Fb br-y

Prev discussion issued 302 pm pst Tue jan 23 2018
short term... A low moving into british columbia is bringing a
cold front near the coast late today which will gradually move
onshore this evening. An upper trough will drop down off the
pacific northwest coast tonight into Wednesday and the surface
front will gradually move eastward across the area through
Wednesday. With this frontal passage, expect areas of strong winds
and heavy mountain snow. Area of moderate snow are expected near
mount shasta city and for areas east of the cascades in klamath
and western lake counties as well. Behind this front, the concern
will shift to lower elevation snow late Wednesday night and
Thursday as snow levels drop to around 2000 feet and locally
lower.

Models remain on track showing this front bringing heavy rain to
the coast with inland areas seeing significant snow over the
higher mountains from the cascades west, with areas of light to
moderate snow east of the cascades. Ahead of the front, expect
strong southerly winds to develop along the coast late this
afternoon into this evening. Winds have begun to increase along
the coast early this afternoon with gusts to around 40 mph. Winds
are forecast to increase further with gusts to 60 mph by this
evening for areas along the coast. For inland areas, strong winds
are also expected to develop late today into Wednesday in the
shasta valley and for areas east of the cascades. Inland areas
will see strong winds persist into early Wednesday afternoon in
the shasta valley and into Wednesday evening east of the cascades
as the front gradually moves across the area. High wind warnings
and wind advisories are in effect for these areas. Please see the
npwmfr for details.

Heavy rain is expected to develop along the coast and in the
coastal mountains by this evening and peak overnight into
Wednesday morning with amounts of 2 to 4 inches of rain expected
for coastal areas. This heavy rain will bring rapid rises on area
streams and rises on area rivers. Localized ponding of water on
roadways is also expected for coastal areas through Wednesday
morning. A hydrologic outlook has been issued for rises on area
rivers. Please see the esfmfr for details.

For areas further inland, moderate precipitation will
spread across western portions of the area this evening and
into Wednesday. A mix of light to moderate precipitation will
spread east of the cascades late tonight and Wednesday. Snow
levels are forecast around 5000 feet in the cascades this evening
as precipitation spreads inland, lowering to 4000 feet late
tonight into Wednesday. Precipitation along with lowering snow
levels, will bring significant snow to the higher mountain passes
in the cascades, over the higher mountains in the siskiyous and to
portions of western, southern-central and eastern siskiyou
county. Snow levels are also expected to lower down to around 3000
feet at times in the mount shasta area on Wednesday. Also with
this frontal band, expect areas of moderate to locally heavy snow
to develop east of the cascades in northern and central klamath
county and over the higher terrain in western lake county on
Wednesday. Of note, strong gusty winds over the mountains and east
of the cascades may bring blowing snow and limited visibilities at
times on Wednesday. Winter storm warnings and winter weather
advisories are in effect. Please see the wswmfr for details.

The upper trough will move overhead Wednesday night and Thursday.

Of concern, models show a shortwave low moving around the trough
and into the region on Thursday. This will bring another round of
precipitation with relatively low snow levels. Snow levels down
to 1500 to 2000 feet are possible Wednesday night and Thursday
morning with light snow accumulations possible on lower mountains
in western areas, including the sexton summit area. Snow levels
may rise slightly during the day Thursday to 2500 feet. Given
model variability and the potential for impacts, will continue
to monitor the track and timing of this shortwave with future
model runs. Moderate snow accumulations are possible Wednesday
night and Thursday over the mountains west of the cascades at and
above 2000 feet elevation and in the mount shasta city area.

Showers are expected to continue into Friday as the upper trough
moves east of the area but moist onshore flow continues. Snow
levels Thursday night into Friday are expected to be around 1500
to 2500 feet and the best area for showers will be along the
coast and inland across douglas and josephine counties and into
the cascades.

Long term... Friday evening through Tuesday. The active pattern
will continue. The ec and GFS have come into better agreement
for this forecast cycle. Considering the run to run changes, and
somewhat inconsistent trends, forecast confidence is not high, but
has improved over yesterday. A low will drift into the marine
waters Friday evening, pushing a warm front through the medford
cwa, bringing a substantial round of precipitation during the day
Saturday, along with some gusty south or southwest winds in the
usual areas... The coast, the shasta valley, and the east side.

Warm air advection will cause rising snow levels throughout the
day. Expect snow levels around 2500 to 3000 feet when
precipitation begins Friday night... Then snow levels will reach
6000 to 6500 feet Saturday night. Another stream of moisture with
subtropical origins will impact the pacific northwest Sunday into
Monday. Right now, it looks like most impacts will be felt in
northern oregon and southern washington, so kept pops as mostly
chance in southern oregon northern cal for now... This feature
will need to be monitored. If the track shifts south, there could
be river flooding concerns. -msc
marine... Updated 200 pm pst Tuesday 23 jan 2018... Seas are
steep and hazardous and will continue to build into this evening
as a cold front approaches. Gales will persist into early
Wednesday morning. Winds will diminish to advisory strength later
Wednesday after the front has moved inland, but seas will remain
high and steep. The next front will bring thunderstorms potential
Wednesday night and Thursday.

Seas will peak again at around 18 to 20 feet Thursday evening.

Winds will slightly decrease Friday then increase again ahead of
the next strong front Friday evening. A series of fronts are
expected to move through this weekend into early next week. -fb

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
