Area Forecast Discussion
National Weather Service Medford OR
225 PM PST Wed Jan 11 2017

.DISCUSSION...

SHORT TERM...Scattered showers will continue over our CWA
tonight... and diminish by tomorrow morning. Snow levels should
hover around 2000 feet... though lower in the Coastal Range. Snow
is possible at the valley floor in the Illinois Valley, though
snow amounts should be under an inch.

A ridge will begin building over the PacNW... which will bring dry,
cold conditions with easterly flow starting tomorrow, and
continuing until the weekend. Expect overnight lows tonight to be
5 to 10 degrees below normal in most areas... and up 15 degrees
below normal east of the Cascades. Most of the coast is under
either freeze warning or frost advisory tonight. Patchy freezing
fog is expected in west side valleys early tomorrow morning, and
during the next several mornings due to stable conditions and
moisture availability. Overnight lows Thursday into Friday will be
around 10 degrees below normal west of the Cascades, and 15 to 25
degrees below normal in the Cascades and east. Dry weather will
continue, but temperatures will begin to warm Friday into
Saturday. -MSC

LONG TERM...Sunday morning through Wednesday night...the extended
period continues with the quiet weather from the short term.
A shortwave disturbance will ride over the upper level ridge in
place Sunday, but models have trended weaker with any moisture
associated with this shortwave. It's more likely that we'll just see
some increased high level cloud cover instead of precipitation, so
have removed mention of showers at the coast for this time. The
upper level ridge axis rebounds behind this shortwave with the axis
extending off the coast and reaching into British Columbia. Monday
also looks to be quiet as the ridge moves inland. The EC shows a
stronger shortwave behind the ridge and brushes a weak front through
the northern portions of the forecast area. The GFS on the other
hand, keeps it dry through Monday night. Even if the EC is right, it
looks like rain amounts would be light and focused mainly along the
coast and north of the Umpqua Divide. Once the ridge moves off to
the east Monday night, the storm door will open again.

Confidence is increasing in the wet, active pattern that will resume
on Tuesday. A lot can change between now and then in regards to
timing and details, but currently it looks like heavy rain and
strong winds will be in place by Tuesday morning. Snow levels will
be high during this time, around 8,000 feet, which could lead to
another round of flooding concerns. However, the soggy pattern looks
to continue through the end of the week and the models are currently
trending lower with snow levels as the week progresses on. This
could result in snow at lower elevations which could alleviate the
flooding threat. However, it's too soon to delve into specifics at
this time. So this will be something to watch and fine tune as
details become more clear. In the meantime, enjoy the break in the
weather! /BR-y

.AVIATION...11/18Z TAF CYCLE...Widespread MVFR conditions with
terrain obscurations will likely continue for the rest of the
morning and into the early afternoon. Conditions may improve between
the scattered showers that are expected to linger through late
afternoon into the evening. Snow levels will linger around 2500 feet
through the day, lowering tonight as conditions begin to dry out.
With all the recent moisture, clearing skies, and stable conditions
developing over the area overnight, expect IFR/LIFR fog and low
clouds to develop in the valleys west of the Cascades. /BR-y
