LIGHT SNOW POSSIBLE ACROSS ALL ELEVATIONS OF NORTHWEST OREGON
LATE TONIGHT INTO FRIDAY MORNING...

CHANCE FOR SIGNIFICANT LOW ELEVATION SNOW ACROSS SOUTHWEST
WASHINGTON AND NORTHWEST OREGON FRIDAY NIGHT AND SATURDAY...

A cold air mass will remain over the Pacific Northwest through the
weekend, potentially lingering well into next week. This will
result in additional chances for low elevation snowfall for
southwest Washington and northwest Oregon, both along the coast
and inland.

The next chance for low elevation snow will be later tonight into
Friday morning, mainly across western Oregon. A band of light
precipitation is expected to develop over the region during this
time, which will likely result in some snow flurries with little
to no accumulation for many locations. However, there are some
indications that a steadier snow band may develop, which could
result in anywhere from a dusting to up to one inch of snow on the
ground by Friday morning. Temperatures will be cold enough for
snow to stick to paved surfaces, so even a small amount of snow
could cause travel issues during the Friday morning commute.

A more significant weather system will arrive Friday night and
Saturday. Snow levels are expected to rise during the day Friday,
with precipitation likely to fall as mainly rain below 1000 feet
through early Friday evening. However, snow levels will be
lowering again Friday night, likely reaching the lowest elevations
by Saturday morning. Heating of the day may allow general snow
levels to rise a few hundred feet above sea level by early
Saturday afternoon, but accumulating snow will still be possible
down to the lowest elevations in any heavier showers. Any wet or
slushy roadways Saturday evening are expected to freeze quickly
overnight, likely remaining frozen well into the day Sunday.
