Sunday 8:15 p.m. update:
This Evening: Scattered showers, mix of snow possible at times all elevations. Best chance of a dusting will be above 500 feet. Icy spots will develop, the city center of Portland will likely remain just above freezing.
Monday: Morning icy spots, scattered showers, snow mix, no big deal. A heavy band of moisture will arrive during the afternoon, likely by 2:00 p.m. Snow levels will sharply fall. Accumulations in the hills near and above 500 feet could reach 4" of snow. The city center of Portland could see rain chance to snow - I am not sure. Arctic air will quickly arrive late day or early evening. If we still have moisture and I think we will, 1-2" of snow will accumulate on the valley floor. The afternoon rush could be in the middle of a "mini" snow storm. It is possible that Portland stays above freezing, but I think we get snow, at least in the evening.
Tuesday: Arctic Air. Very Cold. Early Flurries, Temperatures In The 20S. Becoming Partly Cloudy, Highs Near Freezing.
