Area Forecast Discussion
National Weather Service Medford OR
853 AM PST Tue Jan 10 2017
.DISCUSSION...Steady precipitation is already moving into the area
this morning and will become heavy late this morning through this
afternoon. A quick look at several road cameras show mostly wet
roads along the I-5 corridor with road slush up towards Siskiyou
summit. Meanwhile the Cascade passes and roads east of the
Cascades remain snow covered. Snow levels will continue to rise
during the day and should peak out between 5000 and 5500 feet late
this afternoon. Therefore we should see a transition from snow to
rain at least for a brief time in this time period before snow
levels come back down again this evening and tonight.
Flooding will continue to be a concern, especially during the
period of heavy precipitation. The combination of heavy rain and
snow melt at the lower elevations, especially in areas that
picked up accumulating snow yesterday evening and night will lead
to elevated flood concerns.
The short range models (RAP) suggest precipitation will be
heaviest from around 10 am pst until around 2 pm pdt, but find
this suspect. The NAM and GFS is showing heavy precipitation
persisting until early this evening and we'll follow the timing
of these.
Precipitation rates will gradually decrease tonight, but snow
levels will be coming back down again as colder air moves in. So
we could be dealing with accumulating snow for the Cascade Passes,
Siksyou summit and possibly the summits north of Grants Pass. This
will be looked at in more detail this morning. -Petrucelli

.AVIATION...10/06Z TAF CYCLE...From the Cascades west...MVFR
cigs with areas of IFR cigs/vsbys in rain and snow showers with
higher terrain obscured through tonight. It will remain MVFR with
areas of IFR Tuesday, but precipitation will become all rain below
5000 feet. Precipitation will increase into Tuesday evening and will
be heavy at times. Higher terrain will remain obscured.
East of the Cascades....Areas of MVFR cigs/vsbys and local IFR
cigs/vsbys in light to moderate snow showers. Areas of higher
terrain obscured. Snow showers will increase later tonight into
Tuesday and thus the areas of MVFR will also increase. The snow
will change to rain below 5000 feet Tuesday. It will also be
windy Tuesday.

.MARINE...Updated 230 AM PST Tuesday 10 January 2017...
A strong area of low pressure will bring gales to the northern
California and far southern portion of the Oregon waters for a few
hours from late this morning into the afternoon. Models are coming
into a better agreement on the track of the low. This will bring
shifting winds with a period of easterly winds likely over the
northern portion of the waters while the strong southerly winds
occur over the far south.

.PREV DISCUSSION... /Issued 455 AM PST Tue Jan 10 2017/
DISCUSSION...
Winter weather paid yet another visit to West Side Valleys last
evening through this morning with wet snow falling down to about
1000 feet, and locally lower in the Grant Pass area. Most areas
received 1-3 inches, though there were 4-6 inch reports in the
Grant Pass and higher portions of the Gold Hill areas.
Temperatures have been hovering between 31 and 35 in many
interior West Side valleys overnight. A winter weather advisory
remains in effect for elevations above 1000 feet in Douglas
County, where colder air at the surface is overlaid by colder air
aloft, supporting cooler temperatures and still some snowfall in
places like Camas Valley and Barton Road.
Temperatures have been edging up south of the Umpqua Divide in the
last hour, albeit only by about a degree. This has been enough to
help clear the roads per road cameras. Also of note, it is above
freezing in many of the East Side valleys this morning, and, with
the later arrival of precipitation at Mount Shasta, we expect snow
impacts there to be above about 4,000 feet.
To summarize, today will be the day that will push streams,
rivers, and creeks highest in this recent stretch of storminess.
Mainstem river flooding is expected on the Coquille River at
Coquille and on the South fork at Myrtle Point, as well as on the
Rogue River at Agness. Heavy rainfall today is expected to push
many streams and creeks to very near or even over their banks and
we expect some urban flooding and plenty of ponding on roadways on
the West Side. An Areal Flood Advisory has been issued for this.
Josephine, Siskiyou, and Curry Counties are likely to experience
the bulk of the impacts from the storm activity today.
Of note, there is a possibility of a period of convectively driven
high winds in the coastal waters and in the coastal counties that
could push inland late this morning through this afternoon and
evening. Today's front will be very dynamic, with 700 mb winds
reaching 90 knots over some areas. This means the peaks of the
Cascades will experience life threatening weather today.
Snow levels rise today, but then come back down to potentially
problematic levels late tonight through Thursday morning on the
West Side with some impacts again possible in this time period,
especially in the Sexton/Canyon Pass areas.
It does appear we'll see some colder and drier weather beginning
Thursday into Friday. BTL
