.PREV DISCUSSION... /issued 229 PM PST Wed Jan 1 2020/

SHORT TERM...Today through Friday Night...
A compact shortwave trough continues to move across the region
through fast northwest flow. This feature will be the main weather
maker in the near term, bringing moderate snow to the Cascades
and Blues/Wallowas of northeast Oregon and southeast Washington.
It will also foster unseasonably warm temperatures and windy
conditions through the rest of the afternoon. At this time, given
the rather high snow levels, total snow accumulations look to
remain below advisory criteria, but this will need to be monitored
closely as snow levels begin to fall later today into tonight.
Still expect several inches of snow for elevations above 4000 to
5000 ft.

As we head into Thursday and Friday, a high amplitude ridge will
build in across the Pacific Coast, shifting eastward with time. On
the northern periphery of this feature, another weak shortwave
will continue to generate snow accumulations over the Washington
Cascades through Friday morning. This area of high pressure will
nose into the region for much of the day on Friday with drier and
continued mild temperatures.

Late Friday night into Saturday morning, another storm system
will begin bearing down on the Pacific Coast. This will bring
increasing chances for valley rain and mountain snow as we head
into the weekend.

79/Austin

LONG TERM...Saturday through Wednesday...
A weather system will affect the two state area this weekend with
rain and snow. A challenge could be along the east slopes of the
wa cascades where cold air may be trapped and any pcpn that falls
could be a wintery mix for Saturday morning and perhaps into
portions of the gorge. Meanwhile snow should fall across the
higher elevations while rain showers are expected elsewhere.
Several disturbances will continue to enter the pacnw into the
beginning of the week and keep the unsettled weather in the
forecast with mountains snow and valley rain. A ridge of high
pressure is forecast to build into wa/or Tuesday and drier
conditions are expected. Another weather system is likely for the
middle of the week with increasing clouds and showers possible on
Wednesday. Temperatures through the period should remain slightly
above normal.
