.KEY MESSAGES...

- Low impact weather through Wednesday

- Windy and wet Thursday into Friday

- Mountain snow late Thursday through the weekend

&&

.SYNOPSIS...
Dry, mild conditions continue into the middle of the week. Wet
and windy weather returns Thursday and Friday with snow on the
mountain passes starting Thursday night and lasting into Sunday.

&&

.DISCUSSION...
Today and Tuesday: A pattern change begins today as a trough
begins to dig into the region and flattens the ridge. A weak
wave of moisture will push across the Inland Northwest and bring
mainly mountain showers. Snow levels will drop from 7000ft to
around 4000ft by Tuesday morning. Precip will start as rain
before changing to snow for the Cascades will the rest of the
mountain areas can expect rain or rain/snow mix. Accumulations
are not expected to be as the Cascades have around 20-30% chance
of greater than an inch. While the weak wave passes, a
deepening trough will begin to form along the coast.

Wednesday through Friday: The trough will bring a round of
widespread precip with mountain snow and lowland rains across
the region. The west to east movement will bring the higher snow
amounts to Cascades with around 3 to 6 inches through Friday.
Ensembles have increased the snow amounts slightly from previous
runs. Probability of at least an inch is around 60%. The Idaho
Panhandle and northern mountains will struggle to get more than
inch with around 25% chance. While the low lands will receive
rain, the timing could lead to a possible snow mix Thursday
night into Friday morning. Snow levels will dip below 3000ft
through Friday morning. Highs will start in the 50s and upper
40s and drop a few degrees by Friday. Overnight lows will follow
the same pattern drop into the 20s and low 30s.

The Weekend: Ensembles are expecting another system over the
weekend. Timing between the ensembles are coming in better
agreement for a late Saturday early Sunday morning passage.
Another round of widespread precip over the weekend is expected.
The northern portions of the Basin could see more snow from the
system with very limited accumulations. /JDC

.AVIATION...
12Z TAFS: VFR conditions will prevail through the forecast
period. Around 18Z, a front will move through, bringing lower
ceilings to all TAF sites and rain chances to KGEG/KSFF/KCOE/KPUW.
Ensembles are showing 40-60% chance for MVFR ceilings over
these locations from 18-02Z but the 06z KOTX sounding suggests
lots of dry air to overcome. Chances for rain continue through
06z in southeast WA. Models hinting at lower cigs developing in
eastern WA/north ID Tuesday morning but chances are not high
(20-40% chance).

.FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
High confidence for VFR conditions to persist. Low confidence
for MVFR conditions for KGEG/KSFF/KCOE/KPUW.
-----------------------

Confidence descriptors:
Low - Less than a 30 percent chance
Moderate - 30 to 70 percent chance
High - Greater than a 70 percent chance
