Seattle weather: Widespread rain, mountain snow Tuesday

Tuesday holiday travel in western Washington will be impacted by widespread lowland rain and several inches of mountain snow.

After a dry start, widespread rain will develop by midday Tuesday. 0.5 to 0.75 inches of rain is possible in the Puget Sound lowlands Tuesday with cool high temperatures in the mid 40s.

By the numbers:

The biggest travel impacts will be felt in the Cascades. Even though warmer air is moving in, heavier precipitation could push cold air down from the higher levels of the atmosphere. Three to eight inches of snow is possible at Snoqualmie and Blewett passes.

Six to 10 inches of snow is possible at Stevens and White passes by Wednesday morning. Late Tuesday night, freezing rain or a wintry mix is possible over the passes.

Will it rain on Thanksgiving in Seattle?

What's next:

On Wednesday, the Puget Sound area will get a nice break from the rain. It looks mainly dry through the daylight hours. Widespread rain returns late Wednesday night into early Thursday morning.

For Thanksgiving, it will be wet at times with on and off showers throughout the day. Snow levels will be higher, so it will be just rain over the Cascade passes.

Black Friday and the weekend look dry!
