A storm train will continue to unleash rain in Seattle and snow in the Washington Cascades through the weekend.
The first storm in the series arrived on Wednesday, bringing breezy conditions and rain during the afternoon and overnight.
Steadier rain will fall in Seattle Thursday as a more potent storm arrives. While rain and low clouds may result in some travel delays, the brunt of the rain will be delivered farther south across northern California.
Colder air will allow snow to mix in with rain at major mountain pass level on Thursday. A wintry mix of rain and snow will make roads slippery along heavily traveled mountain passes such as Snoqualmie along I-90 in Washington through the rest of the week. Check with the Washington Department of Travel for any travel restrictions.
Stormy weather will persist straight through the weekend. Southwestern Oregon may get in on some of the heaviest rain of the storms by Sunday. The potential exists for localized flooding along streams and rivers.
Mountain snow may become an even bigger problem for travelers over the weekend as even colder air arrives. Icy and snow-packed roads are possible.
