.SYNOPSIS...
The Inland Northwest continues to be under an active pattern
with several opportunities for impactful mountain snow, light
lowland rain and snow, and breezy winds. A strong low will be
moving along the coast and bring gusty winds to the Basin. Snow
could impact travel through North Washington.

&&

.DISCUSSION...
Today and Wednesday: The upper level trough will remain just
off the West Coast. A strong low will slide South to North along
the Oregon/Washington coastline. Ensembles have come into
better agreement for the track of the low. It will swing a band
of moisture through the Inland Northwest later today and into
Wednesday. Most of the region will see rain as snow levels are
expected to be above 4000 ft for most areas. Rain amounts will
be around a tenth or two. The exception will be the Cascades and
northern valleys. The band will not scour out the cold air and
snow levels remain below 3000 ft. The snow ranged 2 to 5 inches
starting Tuesday night through Wednesday afternoon. Wednesday
afternoon winds behind the band will be breezy. The further west
trend of the low has led to lighter winds speeds than previous
runs. Gusts of 20 to 30 mph are expected. Highs will be in the
30s to 40s. Lows will be in the 30s.

Thursday through Saturday: Weather will be fairly benign to
start Thursday. Another low will being to bring a cold front into
the Pacific Northwest on late Thursday and bring another round
of precip to the Inland Northwest. It is expected to bring
mainly rain for most of the area. The area of snow will be over
the Idaho this time. Rain amounts are still expected to be
light with around a tenth or two. Snow amounts for the Panhandle
range from 2 to 4 for the lower elevations and 3 to 6 inches
for the higher terrain through Saturday morning. Highs will be
in the 30s to 40s. Lows will be in the 30s.

Late Saturday through Monday: Ensembles are showing a broad
shallow ridge building over the region as the Low exits the
region. It will bring a break from the seemingly continuous wet
pattern and drop temperatures closer to season normals. Highs
will be in the 30s. Lows will be in the 20s.

.AVIATION...
18Z TAFs: A frontal passage will result in precipitation at TAF
sites starting around 0Z. Precipitation will be mostly rain
except for at KEAT, which will see a mix of rain and snow. With
increased cloud cover, ceilings will decline back down to
MVFR/IFR. Right now models aren`t favoring LIFR conditions for
anyone but KLWS, and even that will be brief and has moderate
confidence. It will continue raining through the end of this
forecast period and into the next period. Around 16-17Z, wind
gusts will increase to ~20-25kts for KGEG/KSFF/KCOE/KPUW/KMWH.
These wind gusts are expected to continue into the next forecast
period as well.

.FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Moderate to
high confidence for MVFR and local IFR conditions developing
with precipitation. Moderate confidence in precipitation type
being mostly rain except for KEAT, which will get a rain/snow
mix. Moderate confidence in windy conditions developing post
frontal passage. /AS
