Rain showers along the front will move ashore around noon and spread inland during the late afternoon hours. Steady rain is expected to continue until around midnight before decreasing into the early morning hours.

Rainfall totals look to be about 1 to 2 inches at the coast and higher terrain, while the inland valleys will be closer to 0.75 to 1 inch.

The other factor will be winds, especially along the coast. Models show the potential for winds 40 to 50 mph as the front comes ashore. Wind will be less of a factor inland, but it will still be breezy at times gusting to 25 to 30 mph.

Another disturbance will move through on Thursday morning, with steady rain during the midday hours. Rain will turn to showers by the afternoon. Showery weather is expected to continue on Friday as the upper low moves through the region.

Another disturbance will bring more showers on Saturday before drier weather moves in on Sunday and Monday. This dry spell will be short-lived as another system arrives next Tuesday, continuing the relatively active pattern we're seeing. 

In addition to the rain we will see this week, snow in the Cascades will also be a factor. A Winter Storm Warning goes into effect at 4 p.m. Wednesday from Santiam Pass and north, while south Santiam Pass starts at midnight Thursday morning. Both will expire at noon on Friday.

The snow level will be dropping over the next several days, starting at around 6,000 feet on Wednesday and dropping to 4,500 feet by Thursday night and down to 2,500 feet by Saturday. The current forecast is for 12 to 24 inches of snow above 4,500 feet. For reference, Santiam Pass is 4,766 feet and Willamette Pass is 5,090 feet. The majority of accumulation will fall tonight and Thursday afternoon.
