.SHORT TERM...Morning update...The region will be under a northwest
flow today. Meanwhile a surface low will track across British
Columbia. Surface pressure gradients have tightened up across
eastern Washington with locations in the Washington lower basin and
foothills starting to push sustained winds near 30 mph with gusts to
around 40 mph. Should see these winds increase a bit more late this
morning, peaking around noon into the early afternoon. Thus have
issued wind advisories for the Washington lower basin and foothills.
Will see breezy conditions in the lower basin and foothills in
Oregon and in portions of the Kittitas valley. Precip will limited
mainly to the Cascade crest area, with some light precip possible in
the Blues. 90

.LONG TERM...Friday night through Tuesday. The extended will be
fairly active as several systems move across the Pacific northwest
associated with a large upper level trough centered offshore.
Periods of rain and higher elevation snow are likely with a good
west to southwest flow aloft into the region. Both GFS and EURO
bring snow levels down to 1500-3000 feet by Sun/Mon as a cold upper
level system moves across the area. High temperatures look to be
mostly in the 30s and 40s with overnight lows in the 20s and 30s.
Stronger winds aloft at 850 and 700mb could produce occasional
breezy to windy conditions.
