A late season “atmospheric river” is moving over the Northwest, which means heavy rain and humid conditions will continue through at least Saturday.
After that, the National Weather Service says showers and cool weather are expected Sunday and Monday.
The forecast is the latest in a bout of “June gloom” weather.
More than an inch of rain fell in Astoria Thursday, nearly doubling the record of rainfall for the day, set more than 90 years ago.
The June 9 calendar day rainfall for Astoria, OR ended up at 1.23 inches. This shatters the record for the date of 0.72 inches set in 1931. #orwx #pdxtst #AtmosphericRiver

The heavy rain and snowmelt mean the Columbia River will be nearing minor flood stage later in the weekend. Drivers can expect more frequent Interstate Bridge lifts as a result.
The region should see at least a couple of dry days by the middle of the week.
