The National Weather Service has issued a winter storm watch for Eastern Oregon, with heavy snowfall possible in the forecast Sunday night through Tuesday.
According to the notice, snow between 4 and 8 inches is possible in portions of northeast Oregon, including Umatilla, Morrow, Union and Wallowa counties. As much as a foot of snow is expected at higher elevations.
The winter storm is the result of a moist airmass over Oregon expected to combine with cold air moving southward.
Temperatures will drop later in the week, dipping into single digits and teens, according to the forecast.
