correction...

.SHORT TERM...Tonight through Tuesday. Numerous winter weather
advisories and warning are in effect through Tuesday morning. A
vigorous winter storm will track across the two state area tonight
producing accumulating snow. The snow may be initially delayed in
Bend and Redmond due to some downsloping. Otherwise the snow should
persist overnight and into tomorrow especially south of the or/wa
state line. However a brief break in between systems is possible
over south central Washington Monday morning before resuming Monday
afternoon.

Meanwhile an upslope flow along the Blue mountains will produce
heavy snow that has prompted a winter storm warning for this
area. A challenge could be with warmer air that may override the
below freezing surface temps to produce freezing rain over central
Oregon and into the foothills of the blue mountains. Another
challenge is whether the warmer air can mix toward the surface
Monday afternoon and evening especially over central Oregon and at
this time the confidence is low. Some drier air is forecast to push
north and decrease pops in and near Grant county Monday night along
with possible gusty winds that could reach into the foothills of the
blue mountains Tuesday morning.

.LONG TERM...Tuesday night through Sunday...

Tuesday night through Wednesday night...Upper-level low continues to
dip south off the west coast with attendant trough digging south
into the PacNW. Good west to southwest flow ahead of the low will
bring increased temps and thickness aloft and a good plume of Pacific
moisture. Expect likely precip to continue into central OR and
Blues/Wallowas Tues night into Wednesday as the nose of 150kt jet
streak moves inland, with a less chance elsewhere into the Columbia
Basin. With the recent snowfall and cold snap, there is the concern
with the models trending warmer aloft, that freezing rain is
possible in the Columbia Basin, since surface and 2m air temps might
struggle to climb above freezing. Have kept at a slight chance for
now. As the low works inland and the cold front sweeps across the
region Wednesday into Wednesday night, expect a good chance of snow
showers across the area, along with colder temps. Breezy southerly
winds ahead of the low will dissipate through the night Tuesday.

Thursday through Sunday. A ridge is expected to move through the
area Thursday with mainly dry conditions.  The next system will be
nearing the coast Thursday night with moisture spreading into the
area on Friday and a chance of snow through the weekend.
Temperatures will continue to be below normal.  93

&&

.AVIATION...00z Tafs. Brief break between systems through the
evening, but IFR/MVFR conditions will spread from west to east
overnight as the next system spread light snow overnight. Winds will
generally be light, except for RDM/BND where south winds 15-20kts
with gusts to 25kt will begin around 04z and continue through the
period.
