Showers Expected in Seattle for the Weekend

Bryan Dijkhuizen

A few showers are expected to pass over southwest Washington late this afternoon. Through the weekend and into Monday, the weather will remain dry.

A northerly flow will be present above, resulting in a little warming of the air mass, but high temperatures will likely not rise beyond the mid-50s, and low temperatures will be mostly in the 30s, with a little frost possible in the locations that do achieve clear skies at night.

The skies have been a bit sluggish to clear in some regions this Friday afternoon, but the low clouds and morning fog should be spotty during the weekend.

A cold front is expected to travel over the region by the middle of next week, despite the fact that the models disagree on the intensity of a shortwave and front around Tuesday. Unlike the American model, the Canadian model is rapid and showery.

The coldest air is expected to arrive on Tuesday morning, with a spell of Fraser outflow expected around Wednesday morning.

The GFS seems to be somewhere in the middle, with a cold front passing through Tuesday night, followed by a brief period of mild outflow and temperatures that don't actually drop much on Wednesday morning.

In reality, the GFS does not predict much precipitation, except modest convergence zone enhanced snow over the central Cascades on Tuesday night and Wednesday.

A weak system hitting Western Washington on Thursday in the northwest flow aloft, according to the GFS, might bring dry weather to the region on Thursday and Friday next week.
