But before that happens, we have to get through Tuesday. Portland has a slight chance of snow showers through the morning before showers taper off and leave mostly cloudy skies with some possible sun breaks. The snow level will start low but then rise to about 1,000 feet by the afternoon. The high temp will be near 43 degrees.

As bitter Canadian winds travel south, temperatures will continue to shimmy down the thermometer. Monday will likely bring mean flakes around Puget Sound.
