Portland-area weather: More rain Sunday after a record-setting day; sewage … – OregonLive.com
Wow, that was a wet Jan. 17 like we hadn’t seen in a while. In fact, ever.
Portland hit two records for the date: With 1.8 inches of rain, the day easily surpassed the .16 of an inch Jan. 17 typically sees and just squeaked by the 1.76 inches that fell on the date in 1976.
And the 59 degree high temperature on Saturday matched the record set in 1975. On Jan. 17, the average is 47 degrees.
It rained so much that untreated sewage flowed into the Willamette River. Officials warned the public against contacting the river from the Morrison Bridge to the Columbia River, and the water will remain unsafe until 48 hours after the combined sewer system stops overflowing. Portland’s office of Environmental Services hasn’t yet said when that will be.
So what now? Well, Sunday will be wet again, though not quite like Saturday. Showers are likely before 10 p.m., with the National Weather Service putting the chance of precipitation at 70 percent, though it predicts between a tenth and a quarter of an inch of precipitation is possible.
The high drops down a bit to 55 degrees, but it is predicted to get colder later Sunday, with a low of 43.
At the coast, isolated thunderstorms are possible. In the Cascades, snow levels will drop down to the passes, the weather services says.
Martin Luther King Jr. Day will see a 30 percent chance of precipitation, then things clear up for a few days. Wet weather could return Thursday, which holds a slight chance of rain, but the sun comes back Friday.
