.SHORT TERM...Tonight through Tuesday night...A shortwave ridge
continues to move over the area today as a trough remains off
the Pacific NW coast. Southwest flow continues into Monday with
slightly warmer temperatures Monday afternoon. As the trough
slowly moves southeastward, snow showers develop over the higher
terrain of eastern OR on Monday. The trough finally moves inland
on Tuesday and shower chances increase to 60-90 percent. Snow
levels will be around 3500-4500 feet during the precipitation.
Snow amounts will be variable due to the showery nature, but
general snow accumulations of 2 to 4 inches across the
mountains, with higher amounts of 4 to 8 inches over the Elkhorn
and Wallowa Mountains in eastern OR. Showers taper off on
Tuesday evening with cool northwest flow, except near the NV
border where snow showers continue into Wednesday morning.

.LONG TERM...Wednesday through Sunday...Cool northwest flow
continues over the long term, keeping temperatures around 5
degrees below normal. A cold front moves across the area on
Friday bringing breezy conditions and light snow showers to the
mountains. Most of the energy will remain to the north, so
accumulations will be minimal. Stagnant conditions expected
Saturday through the following week with poor mixing as a ridge
amplifies over the western US and inversion conditions
developing.
