The year will go out on a brisk, clear note in the Portland metro area.

Some early fog is expected to dissipate in the morning, the National Weather Service said, giving way to mostly sunny conditions with a high in the low 40s.

New Year's Eve revelers will see some clouds roll in at night, with the overnight low between 30 and 35.

The new year will begin with partly sunny conditions and a high of 40 to 45. Windy conditions are expected near the gorge.

A mostly clear New Year's Day would allow prime viewing of the first supermoon --a full moon that is full at or near its closest point to earth Earth -- of 2018. A supermoon appears 14 percent bigger and 30 percent brighter than a full moon at its farthest point from Earth, according to NASA.

Cool conditions will persist through the week, with highs remaining in the 40s. The metro area is expected to remain dry until at least Wednesday night, when rain returns to the forecast.
