area forecast discussion
national weather service medford or
802 pm pdt Thu oct 19 2017

Discussion 20 00z NAM in.

A strong front is now moving through the medford cwa, bringing
areas of strong winds and heavy rain. The steady precipitation
will change to showers behind the front. Snow levels are
currently quite high, around 7500 feet, but they will drop to 4000
to 4500 feet Friday morning, which is after the heaviest
precipitation is over with. Shower activity will continue into
Friday, but they will be lighter in intensity with less coverage.

The upper trough driving the front will break to the east of the
area Friday and a broad and flat long wave ridge will build in
from the southwest. This will push a warm front north through the
area Saturday. The models are indicating that this system will be
quite wet with plenty of overrunning. Given the low snow levels
that will be in place at the beginning of the event, around 4000
feet, some of the mountainous areas could get a significant shot
of snow late Friday night into Saturday morning before the snow
levels rocket back up to near 10000 feet Saturday afternoon.

Precipitation will diminish quickly Saturday afternoon into
Saturday evening.

The ridge will break to the east of the area Saturday evening, and
flow aloft will turn westerly rather than southwesterly, because
the upstream trough is relatively weak. That trough will ride up
and over the ridge, moving onshore Sunday night. The associated
front will be weak this far south, and won't amount to much in
terms of wind and precipitation. It will bring small craft
south winds to the coastal waters.

The long wave ridge will build in more strongly beginning on
Sunday, and this will bring drier and warmer weather to the area.

Long term discussion... Monday 23 oct through Thursday 26 oct 2017.

High pressure will build into the area and bring dry weather
early next week. Warmer temperatures are expected Monday and
Tuesday with highs in the 70s for western valleys and in the 60s
for eastern valleys. This ridge is forecast to weaken Tuesday
night and Wednesday as a front moves inland to the north. A slight
chance for light precipitation is expected on Wednesday for
portions of the coast and the umpqua valley.

Aviation 20 00z TAF cycle... From the cascades west... A cold front
is now moving through the area, bringing areas of MVFR ifr
cigs vsbys in showers and extensive obscuration of higher terrain.

There will also be low level wind shear ahead of and with the front.

Conditions will improve Friday morning to local MVFR CIGS in showers
with areas of higher terrain obscured. This will persist into Friday
evening. East of the cascades... It will be quite windy with plenty
of turbulence ahead of the front, but conditions will be mostlyVFR
with some obscuration of higher terrain. After the front passes,
area of MVFR CIGS vsbys will develop with more obscuration of higher
terrain. Conditions will improve to isolated MVFR CIGS by Friday
afternoon, but winds will pick up again Friday afternoon.

Marine Updated 800 pm pdt Thursday 19 october 2017... Heavy long
period northwest swell is now building into the waters. This is
creating very high and steep seas along with dangerous surf and
bar conditions. Combined seas will peak at around 21 feet this
evening, then slowly subside into Friday night. However, around
that time another round of strong south winds will develop as a
warm front moves through the area. Gale force winds are likely
over most of the area. Winds and seas will subside again Saturday.

A thermal trough will set up along the coast early next week, and
this will bring strong north winds and steep seas south of cape
blanco beginning Monday and continuing through Tuesday.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
